Senior Software Engineer

Remote (UK-based) | Full-time | Flexible working | Competitive salary + excellent benefits

Do your best work, for the right reasons.

We’re looking for a Senior Software Engineer 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 high-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

You’ll join our AI-Enablement team to build and improve the digital platforms that teachers and pupils rely on every day. Working closely with product managers, designers, researchers, and curriculum specialists, you will develop user-facing applications with AI features utilising technologies such as TypeScript and Next.js. You’ll also interact with our backend systems using PostgreSQL databases and GraphQL APIs. You'll stay ahead of the curve in AI developments across the industry and gain hands-on experience building user-facing AI tools in production.

This is a hands-on role with plenty of scope for technical leadership and mentoring, alongside the opportunity to shape our engineering practices and culture. You'll be part of a supportive and collaborative team that cares deeply about accessibility, usability, and delivering tools that genuinely enhance learning.

�� What You’ll Be Doing

• Development of highly-responsive, accessible web-based AI features

• Designing and writing clean, well-tested code that’s easy to maintain and scale

• Be the expert authority within the engineering team on several important aspects of the code base and maintain a good working knowledge of large parts of the technology stack

• Championing new tools or practices that improve the developer experience

• Supporting and mentoring colleagues across the team

• Taking part in our on-call rota to help keep our products reliable and available

• Collaborating with others across the organisation in multi-disciplinary squads

• Contributing to planning, retros, and the wider culture of Oak

�� What We’re Looking For

• Proven professional experience building AI features with TypeScript and React frameworks (ideally Next.js)

• An understanding of how generative AI works and the ability to balance experimentation on new tools and techniques with building production-ready AI features

• Experience working on cross-functional product teams in agile environments

• Experience building automated test suites and understanding the value of different types of testing (e.g. unit vs integration)

• Desire to build beautiful, easy-to-use digital products with an understanding of the importance of accessibility in all its forms

• Strong collaboration and communication skills

• Comfortable working independently in a remote setup, managing your time and relationships effectively

• A proactive, growth-oriented mindset and a desire to help others thrive

�� 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

  The successful candidate will have a desire to contribute in all areas to ensure Oak's success. You will be comfortable working at pace, with a range of digital systems (including proprietary ones as required), and you will continuously look at ways that the team can keep getting better. You will excel at working as part of a remote team, building relationships and managing your time effectively.

We use the Applied recruitment platform to help reduce bias in our hiring process. 

�� 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
