Full Stack Software Engineer

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.

• Experience with C# and .NET
• Frontend development experience with React
• Proficiency with cloud platforms (preferably AWS, within a serverless architecture)
• 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
• 3 years of hands-on experience in a Full Stack Engineering

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.
