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. .
Skills
* 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
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.
