Android Software Engineer — Agentic AI Platform

About the role

We're building the operating system for the next generation of computing—one where AI agents replace apps and your technology finally works for you instead of the other way around. We're a stealth-mode startup with a world-class founding team with deep roots in consumer AI, extended reality, and wearable technology, including founders of some of the most recognizable hardware and software platforms of the last decade. We're backed by strategic partnerships with leading silicon and manufacturing companies, and we're hiring our first mobile engineers to build the client experience from the ground up. This is a rare opportunity to build a genuinely novel Android experience—not a phone app, but a platform designed from the start to live on your face. Additional product details shared under NDA.

Responsibilities

• Work across two surfaces simultaneously: a standard Android mobile app that mirrors an iOS experience, and an AOSP-based custom Android build running on wearable hardware.
• Make foundational decisions about how an agentic AI platform feels and behaves in a wearable form factor—a problem with no established conventions and very few reference points.
• Prepare for the platform’s transition from AOSP to RTOS, ensuring architecture decisions today remain viable as hardware evolves.
• Collaborate directly with the CEO and a small, high-trust engineering team across Silicon Valley and Paris, including close work with a China-based firmware team handling hardware bring-up.
• Use AI development tools (Cursor, Claude, Copilot) as a core part of your workflow.

What You'll Build

• A standard Android mobile app at feature parity with our existing iOS experience, delivering the Agentic OS to Android users with the same interaction quality and design integrity.
• An AOSP-based client for wearable hardware, building the application layer on top of a custom Android stack running on constrained hardware.
• The agent interaction surface for wearables, defining how users interact with an always-on AI without touchscreens, keyboards, or conventional UI paradigms.
• A platform architecture designed to survive the transition from AOSP to RTOS, ensuring today’s work remains relevant.
• Close integration with the firmware team, bridging the application layer and hardware bring-up work in Shenzhen.
• On-device processing integrations to minimize cloud dependency and maximize local execution on constrained hardware.

Requirements

• 4+ years of Android engineering experience with strong Kotlin skills.
• Solid understanding of Android platform internals, not just application-layer development but how the platform works beneath the surface.
• AOSP experience—having worked with or built on top of the Android Open Source Project is highly desirable for the wearable work.
• Experience with constrained or non-standard hardware environments (wearables, embedded Android, custom form factors, etc.).
• Comfort working at the intersection of application software and hardware, collaborating closely with firmware engineers.
• Familiarity with RTOS concepts (a plus given the planned platform transition).
• Active user of AI-assisted development tools with a point of view on their effective use.
• Strong written English and proven ability to work effectively in a remote and distributed team.

Nice-to-have Skills

• Experience with voice or audio-first interfaces.
• Always-on background processing expertise.
• Custom input methods or non-touch interaction paradigms.
• Wearable or AR platform development.

Benefits

• Salary: $140,000–$170,000 depending on experience.
• Meaningful early-stage equity.
• Full medical, dental, and vision coverage.
• Fully remote with occasional in-person time in Silicon Valley or Paris for key milestones.
