Founding Product Engineer

About the Role

This is a founding-level product engineering role at an early-stage AI consumer startup building an ambient intelligence system that lives across phone, watch, and desktop. You'll own the entire product surface end-to-end — from UX and UI through to the underlying AI agent and ASR pipeline — working directly with the Head of Product to ship features fast, with minimal spec and maximum ownership.

This is a role for a true superstar generalist: someone who combines sharp product judgment with the technical range to build across platforms and AI systems independently. No visa sponsorship is available for this role.

What You'll Do

• Own features end-to-end across mobile, watch, desktop, and the agent/ASR pipeline underneath them.

• Turn Slack threads and one-line asks into shipped, polished product — partnering directly with the Head of Product.

• Make independent UX, UI, backend, and AI/ML trade-offs based on what each feature actually needs.

• Ship improvements to ASR latency and accuracy, wearable reliability, cross-platform meeting detection, and agent responsiveness.

• Take features from design through ship through iteration, driven by real user feedback — no waiting for the next directive.

• Help shape and execute the product roadmap alongside Product and Design.

What We're Looking For

Required (dealbreakers):

• 2+ years of full-time engineering experience shipping consumer features end-to-end across mobile, desktop, wearable, or backend platforms.

• Demonstrated capability across UX, UI, backend, and AI/ML — with shipped end-to-end consumer features across at least two of: mobile, desktop, wearable, or backend.

• Founding or early-stage startup engineering experience (pre-Series B or equivalent scale).

Also required:

• Full-stack product development: ability to make independent trade-offs and ship with minimal specification.

• Real-time and streaming systems experience — built or shipped features requiring low-latency or continuous data pipelines.

• Mobile platform development (iOS, Android, or cross-platform frameworks) with shipped consumer apps.

• Backend systems development — designed and shipped server-side features, APIs, or agent systems.

• Strong product sense demonstrated through shipped work: knows what's worth building and executes without detailed specs.

Nice to have:

• iOS or watchOS development with shipped applications.

• Speech, audio, or ASR ML pipeline experience (audio processing, speech recognition, or similar).

• AI-native consumer app experience — shipped features in LLM-powered or agent-based products.

• Agent or LLM feature-building — implemented agentic workflows or LLM-based features in production.

• Hardware-adjacent or wearable startup background.

Location

This is a hybrid role based in San Francisco, CA. You'll be expected to work in-person regularly with the founding team.

Compensation & Benefits

Compensation details will be discussed during the interview process. As a founding team member, equity will be a meaningful component of the package.
