Are you a Senior Backend Developer who wants to own features end-to-end and build products used at scale?

  • Design, build and ship high-quality backend features end-to-end
  • Take ownership of services from concept → production → optimisation
  • Develop scalable APIs using Node.js / TypeScript
  • Work closely with Product, Design and Tech Leads on roadmap and delivery
  • Improve deployment, testing and engineering standards across the team
  • Mentor others and champion best practices and clean code
  • AWS (ECS, CDK, SNS, SQS, DynamoDB)
  • REST APIs, HTTP, JSON services
  • Automated testing (Jest)
  • CI/CD (GitHub Actions / similar)

What you get:

  • Salary up to 80k plus bonus
  • Fully Remote working
  • Private medical cover
  • And more!
