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 product tradeoffs independently, and collaborate closely with a China-based R&D, hardware, and supply-chain team across time zones.

What You'll Do

• Own app 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 quickly, addressing real issues surfaced from early product use such as watch 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 consumer app experience.

• Collaborate with a shared ASR engineer on backend and pipeline surfaces both roles touch.

• 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 of: mobile, desktop, wearable, or backend.

• Proficiency in Swift/SwiftUI for iOS and watchOS, with shipped apps on both platforms.

• Comfort with TypeScript/React and Electron for Mac/desktop client development.

• Genuine, demonstrated capability across UX, UI, backend, and AI/ML, not deep in one area with surface-level familiarity in others.

• Experience as one of the first engineers at an early-stage or pre-launch startup, shipping features with minimal specification.

• Track record of making independent UX and scope tradeoff decisions and implementing them directly without handoff.

• Demonstrated experience building and integrating agent/LLM-based features into production consumer applications.

• Backend development experience building shared services and APIs that power multiple client surfaces.

• Ownership mindset: you make the call, then implement it directly.

• Nice to have: experience with real-time or streaming systems such as audio processing or live data pipelines; prior work at an AI-native consumer app; experience with wearable devices, hardware, or robotics.
