Product Engineer

ABOUT THE ROLE This is a hands-on, generalist product engineering role at an early-stage ambient AI consumer startup, where you will own the app experience end-to-end across iOS, Apple Watch, and Mac alongside the backend surfaces that power them. You will work directly with product leadership, make real tradeoffs on the fly, and ship user-facing improvements quickly while collaborating across time zones with hardware and R&D teams. WHAT YOU'LL DO - Own features end-to-end across iOS, watchOS, and Mac, working directly with product leadership without a fully specified backlog. - Build and ship user-facing improvements addressing real issues surfaced from early product use, such as wearable tap-target reliability, cross-platform meeting 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, 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 or more years shipping consumer product features end-to-end across at least two of: mobile, desktop, wearable, or backend. - Strong proficiency in Swift/SwiftUI for iOS and watchOS, with shipped apps to show for it. - Proficiency with TypeScript, React, and Electron for desktop/Mac client development. - Genuine, demonstrated capability across UX, UI, backend, and AI/ML, not deep in one area and dabbling in the rest. - Experience as one of the first engineers at an early-stage or pre-launch startup, shipping with minimal specification and undefined requirements. - Hands-on experience building and integrating agent/LLM-based features into production consumer applications. - Backend experience building shared services and APIs that power multiple client surfaces. - Track record of owning features from design through ship through iteration, making independent UX and scope tradeoff decisions and implementing them directly. - Comfort collaborating across time zones with hardware, supply-chain, and R&D teams. - Bonus: experience with real-time or streaming systems such as audio processing or live data pipelines, wearable or hardware product development, or prior work at an AI-native consumer application. COMPENSATION & BENEFITS Salary range: $150,000 to $200,000 USD annually. Visa sponsorship is not available for this role. LOCATION Hybrid, 3 days per week in office. Based in the San Francisco Bay Area, California, United States.
