Job description

Senior Full-Stack Engineer (AI Products)

Location: George, Western Cape | On-site

AI agents aren't products until people can use them. That's where you come in.

About The Role

You'll turn powerful AI systems into real, usable products; the kind customers and teams rely on every day. At ARC AI, we're building intelligent agents that operate in a regulated insurance environment, and your role is to make them work in the real world.

This means designing and building the interfaces, APIs, and product layer that sit between AI and people. You'll shape how users interact with AI: from chat interfaces and workflows to human-in-the-loop review systems that keep humans in control of agent decisions before they reach customers. Ensuring everything works smoothly, even when the AI doesn't.

You'll own the full stack: frontend experiences that handle streaming responses and unpredictable outputs, backend services that connect AI to core systems, and the pipelines that ship it all into production.

You'll also build the observability and feedback loops that help us continuously improve how these agents perform in production, not just in evaluation, but in the real product.

This is a hands-on, high-ownership role where what you build is the product, seen and used by customers and leadership alike.
