About the job:

You will own the vision and execution of local AI products, from roadmap to release. Half your time goes into code, the other half into alignment: defining what to build, why it matters, and how to ship it well. You will lead a pod of engineers across the stack, ensuring that the power of on-device AI translates into products people actually want to use. This role is for builders who care deeply about the end result: making local, private, and powerful AI accessible through thoughtfully designed products.

Responsibilities:

• Aligning stakeholders on the product roadmap by building mockups and writing product requirements documents (PRD).
• Contributing to the product's codebase (at least 50% of your time should be spent coding).
• Managing a cross-functional team (pod) made of middleware (JS), foundation (C++), QA and documentation engineers to produce high-quality deliverables.
• Regularly assessing, both qualitatively and quantitatively, our position in the market with regards to similar products or platforms.
• Leveraging the expertise of the design, where needed, to ensure a high-quality user/developer experience.
• Leveraging the expertise of technical architects to ensure robust architectural choices and code quality.
• Ensuring stable releases by following precise internal release processes.

Requirements:

• Strong software development skills (preferably in Javascript/Typescript and/or C++).
• Extensive experience with React Native / Expo and cross-platform development.
• Good understanding of how LLMs, transformer architecture and other AI building blocks work.
• Built or been a key technical contributor in one or more small to medium-sized products (think 10k+ active users).
• Experience managing a small, specialized, cross-functional team (pod) of 3-5 people.
• Genuine passion for building good products that improve people's lives.
• Knowledge of AI tools such as Cursor or Claude Code to write good code and iterate quickly.

Bonus points if:

• You have experience with AWS, containerization platforms, orchestration, and automated testing suites (Maestro, Appium).
• You have direct experience in building AI-powered products.
• You understand the difficulties, nuances and importance of p2p technology.
• You share a cool project you built that aligns strongly with our vision for local AI (it’s totally fine if you build it after reading this!).
