Cape Town, Western Cape, South Africa Theodo UK Full time R250 000 - R500 000 per year

Role Mission

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.

As a Senior Software Engineer, your mission will be to focus on the backend building a high-impact, cutting edge product used by hundreds of thousands worldwide. .

    expertise, ideally with a
    Serverless focus
    (Lambda, DynamoDB)
  • Strong proficiency in
    C#
  • Solid experience with the
    .NET
  • Proven ability to manage and collaborate with external clients
  • STEM or Computer Science degree
    , or equivalent professional experience

What we Offer

Alongside a competitive salary, we also 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 — ask questions, share patterns, or troubleshoot obscure bugs with some of the sharpest devs out there.
  • Monthly "Lunch & Tells" — in-person sessions to share technical discoveries, cool code tricks, or war stories from the field with fellow engineers.

You'll work on a hybrid basis from our office based in Green Point, Cape Town—a vibrant location, with amenities, beaches, parks, and the CBD all within close proximity.

Values

Team Spirit

Our team has a natural ability to work together to achieve a common goal. Taking on the role of a good teammate requires courage; it means challenging and giving each other feedback. It's key to our teams succeeding

Pragmatism

Achieving effective results by utilising resources efficiently and avoiding unnecessary waste of time, energy and money. Emphasising agile practices, employing concise and direct interactions and engaging in first-hand experiences to challenge beliefs

Willingness to Improve
