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.
