You're the kind of person who thrives on solving hard technical problems, learning from brilliant peers, and getting deep into the codebase — day in, day out. This isn’t solo hacker mode. You’ll be part of a high-performing team and expected to navigate real-world, fast-moving client projects. That means collaborating thoughtfully, communicating clearly, and being proactive in unblocking yourself and others. We want engineers who ask great questions, learn from their teammates, and know how to get what they need to do their best work.

Job Responsibility:

  • Focus on the backend, building a high-impact, cutting edge product used by hundreds of thousands worldwide
  • Solve hard technical problems
  • Collaborate thoughtfully, communicate clearly, and be proactive in unblocking yourself and others
  • Ask great questions, learn from teammates, and know how to get what they need to do their best work
  • Navigate real-world, fast-moving client projects

Requirements:

  • AWS expertise, ideally with a Serverless focus (Lambda, DynamoDB)
  • Strong proficiency in C#
  • Solid experience with .NET
  • Proven ability to manage and collaborate with external clients
  • STEM or Computer Science degree, or equivalent professional experience
  • Hands-on experience in a backend-focused role
What we offer:
  • 22 Days annual leave
  • Learning and Development Support throughout your career at Theodo
  • 3 week work from anywhere policy
  • Equipment budget for your tech set up
  • Company pension
