Senior Software Engineer

We are currently looking for Senior Software Engineers that have experience with our Backend tech stack (TypeScript, Node & AWS)

You'll be building brilliant tech that makes a real difference. We're talking about systems that deliver educational content to millions, supporting teachers across every time zone, and making learning accessible globally. Plus, you'll be part of our international expansion, working with autonomous, product-centric teams who are passionate about what they do.

You’ll use our tech stack..

• React + Next.js + TypeScript for our frontend code
• Node.js + TypeScript for our backend code
• AWS Lambda for serverless computing
• S3 for scalable storage, and NoSQL databases like DynamoDB
• SQS/SNS for messaging
• Continuous deployment with Terraform (IaC) and GitHub Actions
• Vitest + React Testing Library for unit tests and Playwright for browser-based tests / smoke tests

..to craft web applications and digital products that have real impact. These include:

• Discovery & Navigation: Helping our customers find their way around Twinkl's enormous content library by delivering a thoughtful and polished user experience.
• Maths: A React-based game platform designed to support learners through interactive exercises and gamified challenges aligned with educational curricula. It includes progress tracking, adaptive difficulty, and teacher-friendly reporting

Requirements

• Experience with React/Next.js + TypeScript for frontend and/or Node.js + TypeScript for backend.
  • If you can do both, great! But we do understand that not every engineer has a perfect blend of frontend and backend expertise, and that’s okay! If you are experienced in our stack but lean more to one end, but have the desire to learn and grow into a full stack role, we want to hear from you.
• Experience owning your code end-to-end, from design through deployment, in a collaborative DevOps environment.
• You have extensive experience in web development, particularly in large-scale, cloud-based systems with CI/CD practices.
• You bring deep expertise in modern frontend frameworks (especially React) and essential web technologies—HTML, CSS, JavaScript, TypeScript, and accessibility (a11y).
• You are experienced with automated testing and familiar with TDD.
• You’ve worked in product-centric teams that prioritise strong engineering principles like TDD and pair programming and you have a passion for contributing to and strengthening that culture.
• You value Cross-Functional Collaboration and continuous improvement.
