Title: AI Engineer
Location: San Francisco
Company: Thorin
Stage: Seed | Incubated at 8VC
About the RoleWe're looking for a Software Engineer (AI Engineer) to build the foundation of Thorin's user-facing product. This role is ideal for full-stack generalists who love to ship, own features end-to-end, and bring product ideas to life with speed and polish.
You'll work across the stack - building frontend interfaces, backend logic, and everything in between.
This role is high-ownership and high-agency.
What You'll Do- Build and ship core product features from concept to production
- Own frontend and backend logic across key workflows
- Set quality and velocity benchmarks for a high-performance engineering team
- Help shape product direction through close feedback loops with users and stakeholders
- Move quickly and thoughtfully in a zero-to-one environment
What You Bring- Full-stack experience shipping production-grade SaaS or AI-native applications
- Strong product intuition - you care about the user and sweat the details
- Proven ability to work across the stack: frontend frameworks (React), backend systems (Bun, TypeScript), and APIs
- Comfortable with ambiguity, fast iteration, and early-stage startup dynamics
- Passionate about building software that's useful, fast, and delightful
- Bonus: Experience integrating LLMs or building AI-driven workflows
About the Team & Why Thorin- Work closely with a small, highly driven founding team, design partners, and directly with Joe Lonsdale, who remains deeply involved in product vision, strategy, and hiring
- Operate with high agency, rapid iteration, and direct customer exposure from day one
- Help define how a category-defining AI company goes to market from first principles
- Build with the backing of one of the strongest early-stage venture platforms in the industry
