Job Description

We’re building a team of highly-skilled engineers who want one thing above all else: to write excellent code, every day, and continuously level up technically. 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 back end, building a high-impact, cutting edge product used by hundreds of thousands worldwide
  • 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

Requirements

  • Proficiency with AWS, preferably within a serverless architecture (Lambda, DynamoDB, etc.)
  • Strong experience with C# and the .NET
  • Frontend development experience with React
  • Proven ability to manage external clients and build strong working relationships
  • Demonstrated skill in managing stakeholders across technical and non-technical teams
  • STEM or Computer Science degree, or equivalent practical experience
  • Background in Full Stack Engineering, with a strong focus on backend development

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
  • Monthly Socials
  • A Slack network of 600+ engineers across our extended ecosystem
  • Monthly "Lunch & Tells"
