Product Engineer

ABOUT THE ROLE This is a hands-on, generalist product engineering role at an early-stage AI consumer startup, where you'll own the app experience end-to-end across iOS, Apple Watch, and Mac — plus the shared backend surfaces powering them. You'll work directly alongside product leadership, making real product tradeoffs and shipping improvements quickly without waiting for a fully-specified backlog. WHAT YOU'LL DO - Own features end-to-end across iOS, watchOS, and Mac, collaborating closely with product leadership and without a fully-defined backlog. - Build and ship user-facing improvements addressing real issues surfaced from early product use — including wearable reliability, cross-platform detection, and agent responsiveness. - Move fluidly between UX, UI, backend, and AI/ML depending on what each feature needs, making scope and design tradeoffs independently. - Integrate agent and LLM-based features — including tool use, memory, and retrieval — directly into the app experience. - Collaborate with an ASR Engineer on shared backend and pipeline surfaces. - Take features from design through ship through iteration based on real user feedback, without waiting for the next instruction. WHAT WE'RE LOOKING FOR - 3+ years shipping consumer product features end-to-end across at least two platforms (mobile, desktop, wearable, or backend). - Proficiency in Swift/SwiftUI for iOS and watchOS, with shipped apps to show for it. - Proficiency in TypeScript/React and Electron for desktop/Mac client development. - Genuine, demonstrated capability across UX, UI, backend, and AI/ML — not deep in one with dabbling in the rest. - Experience building and integrating agent/LLM-based features into production consumer applications. - Background as one of the first engineers at an early-stage or pre-launch startup, shipping with minimal specification. - Track record of making independent UX/scope tradeoff decisions and implementing them without handoff. - Backend experience building shared services and APIs powering multiple client surfaces. - Experience with real-time or streaming systems (e.g. audio processing, live data pipelines) is a strong plus. - Prior work at an AI-native consumer app or hardware-adjacent startup is a plus. - Experience with wearable devices, hardware, or robotics product development is a plus. COMPENSATION & BENEFITS Salary: $150,000 – $200,000 USD annually. Visa sponsorship is not available. LOCATION Hybrid (3 days/week in office) — San Francisco Bay Area, California, United States.
