Website and optimisation manager jobs

Senior Infrastructure EngineerWhat does it take to keep a charity like ours running? What sits behind every support call answered, every research database accessed, every fundraising campaign delivered? Infrastructure. And the people who build, protect and evolve it.

As a Senior Infrastructure Engineer, you'll play a central role in keeping that foundation strong, secure and ready for what comes next. Reporting to the Infrastructure Services Manager, you'll support, maintain and enhance our enterprise infrastructure across Azure cloud, identity, endpoint, network and core platform services. You'll lead on complex incidents, drive root-cause analysis, and bring the kind of calm, expert thinking that keeps services running and colleagues confident. This is a hands-on role with real scope to influence how we design and operate our infrastructure for the long term.

Please note that this is a 12 month fixed term contract position.

About you:

You're an experienced infrastructure professional who brings both depth of technical knowledge and the mindset of a trusted colleague. You understand that the work you do has real consequences for real people, and that motivates you to get things right. You're equally comfortable diving into a complex incident at pace and stepping back to think about how we build more resilient, secure and cost-effective services over time.

You take security seriously, communicate with clarity across technical and non-technical audiences, and you thrive in environments where collaboration and accountability go hand in hand. You're someone who keeps learning, shares what you know, and makes the team around you better.

You'll have:

- A grounding in enterprise infrastructure – servers, directory services, hybrid identity – and the hands-on experience to back it up.
- Managing and supporting Disaster Recovery services to address continuity of vital business functions.
- Subject matter expertise in Azure: cloud platforms, virtual compute, storage, networking and the governance principles that keep it all accountable.
- A security-first mindset, with practical knowledge of MFA, conditional access, privileged access management and vulnerability remediation.
- Proven networking foundations across WAN, VPN, firewalling and secure remote access.
- The discipline to work within ITSM frameworks and the rigour to maintain accurate configuration and asset data.
- Experience working alongside a Managed Service Provider as part of an augmented team, including managing service quality and accountability.
- A track record of producing documentation that works for diverse audiences – runbooks, procedures, service improvement write-ups.
- Genuine curiosity about the infrastructure landscape and a commitment to staying sharp as it evolves.

What you'll focus on:

- Keeping our hybrid infrastructure secure, stable and performing – day in, day out, and under pressure when it counts.
- Owning complex incidents from first response through to root-cause analysis and lasting fixes.
- Working shoulder-to-shoulder with our Security team to embed good practice across everything we build and run.
- Helping us get more from what we have – through cost optimisation, service rationalisation and smarter configuration.
- Being a dependable partner to suppliers and managed service providers, holding them to the standard our users deserve.
- Championing modern identity protection across the organisation.
- Bringing energy and expertise to a team that genuinely wants to do good work together.

The infrastructure you build here will help us reach more people living with dementia, more quickly, more reliably. If you're ready to bring your infrastructure skills and wider technology expertise to a role with real purpose, we'd love to hear from you.

About Alzheimer's Society

Dementia is the UK's biggest killer. One in three people born in the UK today will develop dementia in their lifetime.

At Alzheimer's Society, we're the UK's leading dementia charity and the only one to tackle all aspects of dementia by giving help and hope to people living with dementia today and in the future. We give vital support to people facing the most frightening times of their lives, while also funding groundbreaking research and campaigning to make dementia the priority it should be.

Together with our supporters, we're working towards a world where dementia no longer devastates lives.

Our values make sure that our focus is clear for the challenges and opportunities ahead and remind us of what we all stand for.

Our commitment to Equity, Diversity, Inclusion & Belonging

We need to ensure the voices around our table better reflect and understand the communities we exist to serve. We strongly encourage individuals to apply who have a disability, impairment or health condition or individuals who identify as Black, Asian or from another minority ethnic background, as these groups are currently under-represented at Alzheimer's Society.

We want everyone we work with, as a colleague, volunteer, supporter, or someone we support, to feel included and that they belong at Alzheimer's Society. 

Our Equity, Diversity and Inclusion Strategy here along with our internal employee forum and Employee Lived Experience network groups help us promote inclusion and belonging, becoming an engaged and inclusive organisation for all our people. 

Our hiring process

During your recruitment process we want to make sure that you bring your whole self and can be at your best. We are working hard to ensure our recruitment process is as inclusive as possible, so please do inform us of your experience and anything you think we could do better by completing our candidate survey when you apply.  Please also contact Alzheimer's Society Talent Acquisition Team for application support or any adjustments you might need.

To ensure fairness and consistency to select the best candidate for this role, all our applications are anonymised up until an interview has been confirmed. We recognise the benefits of AI, but if you're considering using it to submit your application, we encourage you to reflect on the value it truly adds. AI tools often lack the personal touch and authenticity that set candidates apart. We want to hear your unique perspective, experiences, and skills, so we encourage you to showcase them in your own voice.

We try to avoid closing roles early where possible, however if we receive a high volume of applications, we may close earlier than the advertised closing date. Should this occur, we will aim to provide you with at least 48 hours' notice.

We are committed to safer recruitment and ensuring the welfare of those we work with, due to the nature of some of our roles, we might need to carry out a Criminal Record Check at the relevant level. You can read more information via our Website.

Giving back to you

Our employees work hard every day to make a true difference in people's lives. We are proud to support them with a range of benefits, recognition and many options for working agilely, all contributing to a strong work life balance. We also have various learning programmes to support you in your development and help you grow to realise your potential and shape a career with Alzheimer's Society.
