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
