Job Description

Join the UK’s first EdTech unicorn as a Senior Software Engineer on the Trusted Enterprise Platform team. You will build foundational services—including authentication, SSO, and notification delivery—that ensure security and scalability for 1,500+ corporate partners. This role offers the chance to empower thousands of learners through high‑leveraged infrastructure development.

Why this role is remarkable

• Work within a high‑growth environment backed by elite investors like StepStone Group, Lightspeed, and General Catalyst with a $1.7bn valuation.
• Join a culture where AI is the engine; you’ll use cutting‑edge tools like Cursor and Claude to redefine how platform infrastructure is built.

What You Will Do

• Design and maintain mission‑critical services including identity management (SSO/SAML/OAuth) and universal preference systems.
• Build and scale safe release infrastructure that enables product teams to ship code with confidence and high architectural integrity.
• Mentor junior engineers and collaborate with stakeholders to ensure technical debt is managed while delivering incremental value.

The ideal candidate

• 5+ years of backend‑heavy experience building complex data models and APIs using TypeScript or Elixir.
• Strong cloud‑native background with deep expertise in AWS, containerization (Docker/Kubernetes), and Infrastructure‑as‑Code.
• Proven track record of managing enterprise‑scale identity systems or extracting shared services from monolithic architectures.
