Senior Software Engineer Platform Apps & Technologies

Our team builds the platform Apples 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 Apples model-serving infrastructure to bring the best models into engineers hands quickly and safely. Our customers are Apples own developers MLEs and data scientists the people building the products Apple customers a small team with unusually wide surface 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. Thats a tall order and were looking for talented and passionate engineers who love dealing with such challenges.

Were looking for a backend engineer to own and grow the service behind our marketplace and plugin ecosystem the system that lets Apples engineers discover install and trust the MCP servers plugins and skills that extend their agents. This is the registry the API and the database that every harness we ship reads work across the full backend surface: schema design for a growing catalog of plugins/servers/endorsements the content hosting and pipelines that ingest plugin source auth and the supply-chain checks that keep a plugin marketplace from becoming an attack vector. Youll also help harden the service itself for production: real uptime expectations safe staging/prod rollouts and the kind of database and caching decisions that hold up as the catalog and install volume be successful here if you enjoy owning a service end to end and if you like working close to a genuinely new problem space (agent/plugin distribution) where the right abstractions arent settled yet. Youll collaborate closely with the engineers building the client-side harnesses that consume this API and with the security-minded reviewers who keep the catalog safe.
