It systems developer jobs

Crisis is the national charity for people experiencing homelessness. We have embarked on our 10-year strategy for ending homelessness. We know it is not inevitable. We know together we can end it.

Location: Based in London, E1 with flexible homeworking arrangements in line with Crisis’ Hybrid Working Policy

Contract: 12-month fixed term contract or secondment opportunity to support our CRM Transformation programme. If you are applying for this as an external secondment, please flag when submitting your application.

About the role

This is a fixed term role with a clear mission, created specifically to support Crisis’ CRM Transformation programme. We are migrating to a new CRM system, Microsoft Dynamics 365, underpinned by a Modern Data Platform, and the next nine to twelve months are critical as the new platform enters live operation. As Interim Business Systems Manager you will sit at the centre of this transition, collaborating with product owners, developers, suppliers and business stakeholders to make the handover from programme delivery to business-as-usual a success, equipping Crisis with impactful, sustainable systems for fundraising and engagement in support of our mission to end homelessness.

Coaching and developing our Product Owners will be at the heart of this role, helping them build the confidence and capability to own their backlogs, prioritise with clarity and bring well-formed decisions to the table, alongside embedding consistent, sustainable development practices across the team. You will also lead key transition deliverables, including the rebuild of Apteco FastStats so that marketing delivery remains robust and well-governed, and provide governance, oversight and transition planning for our Christmas systems cycle.

This role exists to support a defined period of transformation; it is offered on a fixed term basis, and decisions about how the team is shaped beyond the transition will be made as the programme concludes. What we can offer now is a bold, genuinely pivotal piece of work, and the opportunity to leave Crisis with a stronger, more confident and capable systems team.

About you

• Demonstrable experience of leading technology teams through significant change, such as service transition, operating model shifts or go-live readiness
• Strong working knowledge of Microsoft Dynamics 365 or similar enterprise CRM platforms
• A solid grounding in service management principles (ITIL or equivalent), with practical experience of establishing support models and change governance
• A track record of building or improving development practices, from sprint discipline and documentation through to release management and peer review
• Experience of developing product ownership, solution design and business analysis capability in others
• Strong stakeholder management skills and the confidence to work at pace with ambiguity

Do your best work, for the right reasons.

We're looking for a Senior Software Engineer (AI/ML) to help us build beautifully simple, high-impact digital products that support teachers and improve outcomes for pupils across the UK.

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 are looking for an experienced Senior Software Engineer (AI/ML) to join our AI Platform team.

Oak's AI Platform team builds and maintains our core AI infrastructure, including shared services, prompt libraries and reusable pipelines. This is essential in enabling our product squads to deliver safe, effective and scalable AI features that support teachers and pupils across the UK.

You'll take a leading role in shaping Oak's AI Platform, contributing towards the technical direction for reliable, safe and scalable AI capabilities. You'll work with product squads to turn ambiguous problems into robust solutions, provide technical guidance and mentorship to engineers, and help establish the patterns, tooling and standards that enable responsible AI delivery across Oak.

You'll work across the boundary between machine learning and software engineering: taking the same ownership of production reliability, testing and developer experience as other senior engineers on the team, while keeping safety and responsible AI at the centre of what you build.

In this role, you may work on:

• Enhancing Retrieval-Augmented Generation (RAG) pipelines, including context chunking, prompt construction and implementing strategies to improve relevance and accuracy.

• Optimising embedding and vector similarity systems through semantic search, clustering, filtering logic and dimensionality reduction techniques.

• Supporting model evaluation and safety tooling, such as automated test harnesses, hallucination detection, content moderation and input guardrails.

• Contributing to model fine-tuning, prompting and deployment, with a focus on balancing performance, accuracy and cost-effectiveness.

🔧 What You'll Be Doing

• Lead the continuous improvement of Oak's machine learning models and systems, from prototype through to production at scale.

• Develop and maintain highly performant ed-tech applications that are secure, scalable, highly available and accessible to the widest number of users, meeting Government Digital Service standards.

• Be an expert authority within the engineering team on the architecture, code base and AI/ML best practices, providing mentorship to less experienced colleagues.

• Design and coordinate the integration of AI/ML models with existing Oak systems, ensuring robust model serving and end-to-end testing.

• Take responsibility for the operation and reliability of production services you build — monitoring performance, resolving issues, and addressing capacity constraints before they affect users.

• Lead the implementation of new processes or tools that improve the user or developer experience.

• As a member of the Oak team, contribute to the planning and culture of the organisation.

• Work in cross-functional and product-oriented squads with colleagues from across the organisation, as required.

• Deputise for more senior colleagues and take on other general responsibilities as required.

🌱 What We're Looking For

• 5+ years' experience leading the continuous improvement of machine learning models and systems in production, alongside significant experience architecting and building high-performing web applications with modern JavaScript libraries and tools.

• Extensive knowledge of machine learning frameworks and cloud-based machine learning tools, with experience moving models from development to production.

• Understanding of machine learning ethics, fairness frameworks and responsible AI principles, including bias detection and privacy-preserving data practices.

• Experience building evaluation frameworks and automated test harnesses for AI/ML systems from scratch. Including techniques for detecting hallucinations, measuring output quality, and monitoring model performance and safety in production.

• Proven experience proposing and implementing new processes or tools that improve developer experience and lead to higher quality products.

• Experience collaborating with product teams to lead the development of high-quality, high-impact products, with great communication and collaborative skills.

💛 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.

📌 Key Info

• 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 and some questions related to your day-to-day job. Your answers will go through our sift process: all answers will be anonymised, randomised, and then reviewed by a panel of reviewers (real humans), so it's your thinking that gets assessed, not your CV.

If you're shortlisted, we'll invite you to interview across three stages. We're aiming to start interviews the week beginning 17th August 2026.

Stage 1: An introductory call to learn more about your skills and experience, and a chance for you to ask us about the role. This takes about 30 minutes.

Stage 2: A technical interview over Zoom, combining a hands-on pairing session or technical walk-through, followed by some technical interview questions. This takes around two hours.

Stage 3: A collaboration interview, focused on how you work with both engineering and non-engineering colleagues. This takes about 1 hour.

We love giving feedback, so at the end of the application process, we'll share our assessment of your performance.

We are receiving excellent responses to our job advertisements. This may lead us to close the role early, so if you are considering applying, don't leave it too long to avoid missing out.
