Product Engineer

Department: Engineering

Location: San Francisco

Employment Type: FullTime

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.
