Rosebank, Johannesburg
- Hybrid after onboarding
- Permanent
Own a live platform. Set the standard. Build the team's engineering foundations.
Our client runs a live, revenue-generating retail-media and connectivity platform used every day by consumers across South Africa's informal-trade market, with some of the country's best-known consumer brands buying media and insights on top of the data. Product development is moving in-house, and they are building a small engineering team from scratch. This is the first and most senior hire.
What You'll Own
- The .NET 8 API, the databases, the Azure environments and the release pipeline
- Taking over the platform from the current development partner and becoming the person who understands how it runs end to end
- Setting coding and release standards, and mentoring a second engineer into the API
- Working across API, database and frontend when the work needs it
What You'll Bring
- Solid commercial C# / .NET experience (the codebase is .NET 8: Minimal APIs, EF Core, Identity/JWT)
- SQL Server and relational data modelling, including migrations on a large existing schema
- Azure in production: App Service or containers, CI/CD pipelines, configuration and secrets
- Experience taking over or working on a system you didn't build
- A full-stack mindset, self-direction and genuine curiosity about the product and its users
Nice to have:
MassTransit / Azure Service Bus or other event-driven work, ClickHouse or another columnar database, captive portal / WISP / ISP exposure, daily use of AI coding tools. No networking or hardware certifications needed.
Why this role
- Real ownership: you set the standards for a new in-house team
- A full roadmap: owner portal (PWA), a client data product, data pipelines, hardware integrations and automated reporting
- Modern stack, senior technical lead for support, and AI-assisted development in daily use
- Work that reaches thousands of small businesses and their customers
Work model:
office-based in Rosebank for the first three months while you learn the platform and the team, then hybrid: three days in the office, two from home.
Package:
market-related, depending on experience.
