AI Software Engineer, App Intelligence

Job description

Do you want to build the layer that lets every app on the device do its best work for the user through Siri? App Intelligence is the on-device system that turns app capabilities into things a user can simply ask for — and makes the assistant reliable enough to be trusted with them. We are engineers, scientists, and problem solvers bringing smarter, faster, and more natural interaction with apps to Siri. We are looking for seasoned AI Software Engineers to join our team and be part of this mission. Minimum Qualifications: 4+ years experience developing and shipping production software Strong proficiency in Swift, Objective-C or C++ Experience building product features on top of large language models — designing tool and function-calling interfaces, constructing context, and validating model output Fluency with agentic coding tools for accelerating engineering productivity, with good judgment about where to apply them and how to verify what they produce Exceptional problem-solving skills, and the ability to drive alignment across teams on shared API surfaces Proven ability to excel in a fast-paced development team Preferred Qualifications: Experience designing and developing systems that are efficient in resource constrained environments — latency, memory, and power budgets on device Experience building the scaffolding around models — tool interfaces, retrieval and context construction, output validation — with strong intuition for model behavior and failure modes Experience building key software components and APIs used cross functionally across different applications and platforms, including versioning and compatibility of interfaces that shipped clients depend on Experience with evaluation, benchmarking, and telemetry for systems whose output is probabilistic rather than deterministic
