## Job description

Our team builds the platform Apple's engineers use to work with AI agents: the coding agents themselves, the registry and marketplace that distributes the tools and extensions they run, and the sandboxing, identity, and supply-chain controls that make it safe to give an agent real access. We work closely with frontier labs and the teams that run Apple's model-serving infrastructure to bring the best models into engineers' hands quickly and safely.

Our customers are Apple's own developers, MLEs, and data scientists — the people building the products Apple customers love. We're a small team with unusually wide surface area. In a given month you might harden a CLI that ships to thousands of engineers, isolate an agent inside a VM, design the trust model for a plugin ecosystem, or make a new model available across every harness we support. We ship on short cycles and we live on everything we build.

Our systems have to scale, stay highly available, and "just work." That's a tall order, and we're looking for talented and passionate engineers who love dealing with such challenges.
