About us

Christian Aid exists to create a world where everyone can live a full life, free from poverty. We are a global movement of people, churches and local organisations who passionately champion dignity, equality and justice worldwide. We are the changemakers, the peacemakers, the mighty of heart.

We’re committed to building a diverse and inclusive workplace, and recognise the value this brings in forming strong, creative and high performing teams. We welcome applications from all sections of the community, and from those with experience from outside of the voluntary sector. And no, you don’t have to be Christian to work here – we encourage people of all faiths and none to apply. We just ask that everyone lives out our values of dignity, equality, justice and love. We value a good work-life balance, so we’re open to part-time and flexible working. We also offer hybrid working for our office-based colleagues. 

About the role

In this role, you’ll be a senior, hands‑on contributor to the design and delivery of solutions, with a particular focus on our Microsoft Dynamics platform, helping ensure it delivers meaningful outcomes across the organisation. You’ll act as a technical authority within the ICT team, owning complex development work, influencing technical direction, and upholding high standards of quality, security, and maintainability.

Working closely with colleagues across ICT and CRM, you'll solve complex technical challenges, champion best practice, and ensure the delivery of high-quality features that align with organisational goals. You'll build strong, open relationships with internal stakeholders and external suppliers, protect the team's focus, and introduce new technologies where they can add long-term value. As a senior practitioner in the Dynamics ecosystem, you'll provide trusted advice on platform capabilities, integration opportunities, and strategic enhancements that help the organisation get the most from its CRM systems.

About you

You’ll bring substantial hands‑on experience designing and delivering solutions using Microsoft Dynamics and the Power Platform, supported by a relevant professional qualification. You have strong expertise in Dynamics customisation and extension, data modelling, integrations and APIs, and SQL Server, alongside solid experience with modern software engineering practices such as source control, automated testing, code review, and CI/CD.

You’re comfortable taking ownership of complex work in resource‑constrained environments, improving quality and reliability, and working directly with users to translate real needs into effective solutions. You understand the long‑term impact of technical decisions and are able to balance pragmatism with sound design.

Ideally, you’ll also bring Microsoft certifications, experience working in a not‑for‑profit or mission‑driven context, and familiarity with Azure or similar cloud platforms.

Above all, you’re a collaborative and credible senior developer who communicates clearly, works effectively with suppliers and non‑technical colleagues, and influences technical decisions through expertise and judgment. You value learning and contribute positively to a culture of continuous improvement.

Please see the role profile for a detailed breakdown of the skills, knowledge and experience required for this role.

Product Lead – HOSTHub  

(Operational Product Delivery) 

Reports to: Operations Director (Head of Delivery) 
Contract: 1.0 FTE (Temp to Perm) 
Location: Remote (UK or International) 

Role Purpose 

The Product Lead – HOSTHub is responsible for identifying, prioritising, and resolving day-to-day product challenges across HOST’s digital platform. 

HOSTHub serves as the operational backbone of the organisation, enabling delivery across finance, legal, partnerships, and hosted partner services. In this role, the Product Lead ensures the platform functions effectively in practice—by understanding user needs, surfacing issues early, and driving the design, prioritisation, and rapid delivery of solutions. 

While contributing to the longer-term product vision in collaboration with the leadership team and development partners, the primary focus remains on operational product delivery. This includes managing fortnightly sprint cycles, maintaining a dynamic and prioritised backlog, and ensuring continuous alignment between user requirements, internal processes, and platform capabilities. 

The role requires a highly hands-on individual who thrives at the intersection of users, internal teams, and developers, with the ability to translate real-world challenges into clear, actionable product decisions. 

Core Responsibilities 

1. Product Problem Identification and Prioritisation 

Lead the ongoing identification of friction points, inefficiencies, and system gaps across HOSTHub use cases, including those impacting hosted partners, funders, and internal staff workflows. 

Maintain a dynamic, prioritised backlog of product issues and enhancements, informed by user insight and operational impact. 

Work closely with delivery teams across finance, legal, partnerships, and community support to understand how the platform performs in practice and where it falls short of user needs. 

Translate operational challenges into clear, well-defined product requirements that are actionable for development teams. 

Ensure prioritisation is driven by delivery urgency, risk exposure, and opportunities for efficiency, rather than abstract feature development. 

2. Sprint Management and Delivery Execution 

Own the end-to-end delivery of the product, managing fortnightly sprint cycles. 

Set sprint priorities, create and refine tickets, and ensure all development work is well-scoped, logically sequenced, and ready for delivery. 

Collaborate directly with development contractors to run sprint planning, stand-ups (where applicable), and sprint reviews. 

Validate completed work against real user workflows before release to ensure quality and usability. 

Maintain clear visibility of progress, risks, and dependencies, escalating blockers and trade-offs to the Operations Director as needed. 

Provide bi-weekly sprint reports outlining delivered outcomes, outstanding issues, and upcoming priorities. 

3. User Engagement and Feedback Loops 

Establish continuous feedback loops with both internal users (staff teams) and external stakeholders (hosted partners and funders). 

Conduct structured user conversations to understand how systems are used in practice, not just how they were designed to be used. 

Validate proposed solutions with users prior to development where appropriate, ensuring alignment with real needs. 

Ensure user insights consistently inform backlog prioritisation and shape sprint scope. 

Maintain a clear view of user satisfaction grounded in qualitative feedback, not just survey-based metrics. 

4. Cross-Team Operational Alignment 

Act as the central point of coordination across product, delivery teams, and external developers. 

Ensure HOSTHub effectively supports real operational workflows across key service areas, including Project Hosting, Hosted Grantmaking, and Capacity Building. 

Partner closely with Finance, Legal, and Partnerships teams to align system functionality with compliance, contractual, and reporting requirements. 

Identify and resolve misalignments between team processes and platform functionality, either by adapting the system or clarifying and standardising ways of working. 

5. Development Oversight  

Manage the day-to-day relationship with the development team, ensuring requirements are clear and issues are addressed promptly. 

Ensure all development outputs are practical, functional, and aligned with real operational needs. 

Avoid over-specification and unnecessary complexity, prioritising simple, implementable solutions. 

Track defects, rework, and technical debt, incorporating them into sprint priorities where they have a meaningful operational impact. 

6. Data, Workflow, and System Effectiveness 

Ensure HOSTHub captures and delivers data that is accurate, actionable, and aligned with reporting requirements. 

Identify and implement opportunities to automate key workflows, reducing manual effort across teams. 

Partner with internal stakeholders to ensure system logic supports compliance and audit requirements in day-to-day operations. 

Maintain clear, practical documentation of key workflows and system behaviours to support effective operational use. 

7. Risk, Compliance, and System Integrity 

Work closely with the Legal Lead and Operations Director to ensure product decisions do not introduce unmanaged risk. 

Prioritise data protection, security, and system reliability as core product considerations. 

Ensure compliance requirements, including data protection and financial controls, are embedded in how the platform operates in practice. 

Take clear ownership of system incidents or failures, coordinating response and ensuring timely resolution and follow-through. 

8. Contribution to Product Direction 

Contribute to longer-term product thinking, including roadmap development and the ongoing evolution of the system. 

Provide grounded input to strategy based on observed user behaviour, operational constraints, and delivery realities. 

Ensure product direction remains focused on solutions that are practical, scalable, and genuinely valuable to users. 

Key Relationships 

Internal: Operations Director, Finance Team, Legal Lead, Partnerships Director, Community Support Team, Data Analyst, Training Lead. 

External: Developers, technical providers, hosted partners, funders. 

Performance Indicators 

Reliable delivery against sprint commitments, with a clear connection to resolved operational issues. 

Reduction in recurring user-reported problems across key workflows. 

Demonstrable improvements in system usability and efficiency for internal teams and hosted partners. 

A well-maintained backlog with clear, transparent prioritisation rationale. 

Strong alignment between platform functionality and operational delivery needs. 

Timely identification and effective resolution of system risks and critical defects. 

Required Experience 

5–8 years’ experience in hands-on product management or product delivery roles, with clear ownership of day-to-day execution. 

Proven experience managing sprint cycles and working directly with developers to deliver iterative improvements. 

Strong track record of identifying user needs and translating them into effective product solutions. 

Experience working with complex operational systems involving multiple user groups and workflows. 

Ability to operate effectively in environments with evolving and loosely defined requirements. 

Comfortable working across technical and non-technical teams, acting as a practical bridge between them. 

Familiarity with system integrations, workflow tools, and data-driven platforms (e.g. CRM systems, finance platforms automation tools) 

Strong prioritisation skills, with the ability to balance urgency, impact, and feasibility. 

Clear, structured communication style, enabling effective coordination and delivery clarity across teams. 

Platform Engineer

Remote (UK-based) | Full-time | Salary: £71,043 + benefits including 4.5-day week and 11% employer pension

Do your best work, for the right reasons.

Oak is a fully remote, mission-driven organisation offering high levels of flexibility, autonomy, and purpose. We’re a national not-for-profit working in partnership with teachers to create the highest-quality, sequenced curriculum and lesson resources for pupils across all subjects and age groups.

Our culture has been independently recognised through:

• Flexa verified (93% overall score, including 95% for working hours and 97% for role modelling)

• Escape the City's Top 1% Employers – based on anonymous colleague reviews of culture, development, and impact

• Investors in People Gold - through external accreditation and colleague feedback

�� About the Role

We've built a lot, fast. Now we want to make it last.

As a young organisation, we've used modern technology to move quickly and get remarkable products into teachers' hands. We've proven what's possible. Now we're maturing, making sure the foundations are as strong as what's built on top of them. We see this role as central to that change.

You'll work with engineering, product, and research colleagues to build confidence in using observability principles that deepen our understanding of how teachers and pupils use our products, and help us keep improving them. We work in product squads alongside designers, researchers, and education experts, regularly releasing new features and improvements so teachers and pupils get quick and easy access to the highest quality learning resources.

Alongside other members of the platform engineering group, you'll enable squads to move more quickly by optimising tooling and implementing automations, including the effective and safe use of AI. You'll drive the creation and adoption of engineering standards across code, deployment, security, observability, and monitoring. And you'll be a key driver of automation, working with the rest of the platform team to improve the overall developer experience.

You'll need a good understanding of platform engineering in a SaaS-heavy environment and the value it brings to an organisation. A solid grounding in development practices, security fundamentals, and infrastructure operation matters. But specific technical skills are less important to us than a passion for automation, an ability to understand complex systems, and a pragmatic engineering approach.

As part of the Oak team, you'll contribute to the wider success and culture of the organisation, and support and role model our five values: create the right environment, be a great colleague, own your role but work for the team, make things happen, and keep getting better.

��What you'll be doing:

• Leading continuous improvement of the observability, performance, and reliability of our web applications (Next.js, JavaScript, TypeScript, Node) and serverless functions (Google Cloud Functions, Cloudflare), deployed on Vercel and Cloudflare

• Helping teams maintain high service quality by promoting a culture of quality across engineering and product, and enabling squads to use SLOs and SLAs effectively

• Contributing to the strategy and evolution of our monitoring, logging, and reporting solutions so developers can resolve problems quickly and get meaningful insights into application behaviour

• Identifying and implementing automations that speed up development, improve security, or raise the quality of what we deliver

• Working in cross-functional, product-oriented squads with colleagues from across the organisation

• Deputising for other members of the platform team and taking on broader responsibilities as needed

�� What we're looking for

You'll have strong professional experience working with event-driven architectures using serverless technologies such as Google Cloud Run, AWS Lambda, or Azure Serverless.

Beyond that, you'll bring:

• Demonstrable experience collaboratively designing and implementing observability, monitoring, and reporting solutions for complex cloud infrastructures in a major cloud provider (GCP, AWS, or Azure), including solutions for squad-specific use cases

• Confidence reading and maintaining web application code, with the ability to design and build small apps, preferably in JavaScript or TypeScript

• Experience with cloud computing platforms and a working familiarity with Infrastructure as Code tools

• A collaborative approach, comfortable promoting and leading collaboration with both technical and non-technical stakeholders, and able to frame work in terms of impact.

You'll want to contribute in all areas, not just your own lane. You'll be comfortable working at pace across a range of digital systems, always looking for ways the team can keep getting better. And you'll be excellent at remote working, building relationships and managing your time effectively.

Specific technical skills matter less to us than a sound engineering mindset and the ability to bring others with you.

�� Our Benefits

• 25 days annual leave, plus one extra day for each year of service (up to 28)

• Additional Oak closure days over Christmas/New Year

• 11% employer pension contribution (with no minimum employee contribution)

• A 36-hour working week, with half-days on Fridays or every other Friday off

• Fully remote working — we’ll support your home set-up and offer coworking options if preferred

• Twice-yearly in-person offsites to collaborate, connect, and have fun

• A culture that genuinely supports flexibility, autonomy, and trust

�� Inclusion and Belonging

We believe diverse teams build better products. We warmly welcome applicants from all backgrounds, particularly those who are underrepresented in the tech and education sectors. 

If you're from an underrepresented group, there's a good chance you're discounting yourself before you've even started. That's more common than you'd think, and it means we may miss out on brilliant people. If you're excited by this role but don't meet every requirement, please apply anyway.

We use the Applied platform to help reduce bias in our hiring process. Answers are anonymised and reviewed by a panel of humans.

• Location: Remote, but you must be based in the UK with the legal right to work here

• Sponsorship: Unfortunately, we’re unable to offer visa sponsorship at this time

• Closing date: We’ll be reviewing applications as they come in and may close the role early

If this sounds like the kind of role and team where you could do your life’s best work, we’d love to hear from you.

Next steps

You'll answer a few admin questions followed by three questions about your day-to-day work. Answers are anonymised, randomised, and reviewed by a panel, so it's your thinking that gets assessed, not your CV.
