Job description

About the Company Our client is a seed-stage AI startup in San Francisco building a personal work agent delivered as a browser: it uses your existing logins, sessions, and context to complete work on your behalf across the web. Its browser agent posts top-tier results on industry web-agent benchmarks and runs local-first, with memory and data protected on the user's device. Tens of thousands of people already use the product, and usage is growing rapidly week over week. About the Role The company is hiring a Product Engineer (Member of Technical Staff) to own features end-to-end, from the first line of code through delivery to users. The team is small and talent-dense, and everyone ships with broad ownership. You will work directly with the founders, hear from users daily, and build screens and product surfaces that make the agent more useful for tens of thousands of people. This is a zero-to-one role for someone with strong product sense who can compose interfaces, make clear calls on what to ship, and take full credit for the work. What You'll Own • Build product features end-to-end: design the interaction, write the code, and get it shipped to users yourself • Listen to user feedback from the community and interviews, triage what matters, and fix issues directly • Compose UI and UX components to build polished, usable product screens without relying on a dedicated design engineer • Demo your work to the team and the user community, and iterate based on what you learn • Work directly alongside the founders and CPO on product direction, contributing to architecture and scope decisions Requirements Must-Have • 1+ years of real engineering experience (internships do not count toward this bar) • TypeScript proficiency: able to read, write, and ship production TypeScript code • Demonstrated ability to build features end-to-end and zero-to-one, owning the entire scope from design through delivery • Strong product sense: can make clear calls on what to ship and why, and can explain those decisions • Comfortable composing UI and UX components to build complete product screens (not a design engineer, but capable of building screens independently) • In-person at the San Francisco office five days a week, or willing to relocate to San Francisco Nice-to-Have • Big tech background paired with startup experience • Active user of AI tools beyond basic chat interfaces (e.g., Claude Code and similar developer tooling) • Hands-on experience with AI browser agents or personal productivity agents • Portfolio of shipped product work that can be reviewed and discussed Key Details • Location: San Francisco, CA (in-person, 5 days a week; relocation support available) • Employment: Full-time • Experience: 1+ years (excluding internships) • Salary: $160,000 – $300,000 USD per year • Equity: 0.5% – 1.5% • Visa Sponsorship: OPT only Benefits & Perks • 0.5% – 1.5% equity • Co-living house (relocation support available) Interview Process • Intro call with a founder • Technical/coding round with the CTO • Behavioral round with the team • Offer Required Candidate Questions Please include the following with your application: • Link to your portfolio
