Full Stack Product Engineer

Quill is the private & powerful conversational notetaker that works everywhere and uses conversations to build a personal database of knowledge and contacts.

We believe in a world where humans control AI, not the other way around – which we build into our product with our values of privacy, power, and quality.

We are expanding our team and looking for self-directed builders with taste who can take features from sketch to production, learn from metrics and user feedback, and leverage modern tools to move as fast as possible. We value a small, highly-leveraged team; if you agree that is the most fun way to work, you will fit in well.

You will…

• Own major product initiatives and their success—examples: e2e syncing and backup, support for self-hosted LLMs, or using agents & MCP to enable users to customize powerful workflows and integrations
• Quickly prototype innovative features and turn new AI capabilities into products for our users
• Collaborate with design, founders, and customers to polish UX and delight our users
• Work across our stack(TypeScript, Electron, Node, Postgres, AWS)
• Continually improve code quality and find ways to make AI more successful internally to increase our operational impact and speed.

You probably have…

• 5-8 yrs full-stack experience, at least 3 in seed-to-Series B startups where you shipped user-facing features autonomously.
• Comfort diving into unfamiliar areas—desktop Electron quirks one week, backend performance the next.
• An almost unhealthy interest in AI architecture and capabilities
• Taste for product, for clean, observable code, and for data privacy.

You are excited about…

• Local and distributed AI
• User control
• Privacy
• Nice-to-haves
• Electron or desktop app expertise
• Svelte UI experience
• Design skills

Success after 6 months

• You’ve successfully launched multiple high-impact features end-to-end
• High usage and low error rates on the services you touch
• The rest of the team counts on you for your perspective and trusts you to deliver and ship quickly and reliably

How we work

• Small, senior, high-trust team. Decisions in hours, not weeks.
• Hybrid SF / remote; core overlap 9 am-2 pm PT.
• Equity meaningful; salary benchmarked to top-quartile startups.
