Protium is hiring Senior Backend C#/.NET Engineers to join our team in Cape Town.
We’re looking for senior backend engineers who can help us design, build, and ship production-grade APIs, services, integrations, and backend systems using C#, .NET, SQL Server, and Microsoft/Azure technologies.
This is a Cape Town-based hybrid role, with in-person office days typically 2–3 times per week at our Claremont office.
You’ll work on high-quality, API-driven systems where clean architecture, maintainability, performance, security, scalability, operational reliability, and long-term supportability matter.
As a senior engineer, you’ll be expected to take ownership of meaningful areas of delivery, shape technical approaches, make sensible trade-offs, guide implementation, support other developers, and help maintain strong engineering standards across the team.
