Founding Engineer

Job description

Hobbes is a self-improving agent that runs product demos today and full sales conversations soon. Arjun (CTO) and Chirag (CEO) are the team today. You'd be the second engineer: real-time voice, generative UI that redraws itself based on who's watching, custom LLM orchestration, eval loops that actually move the needle. The roadmap isn't written. You'll help write it. ## About Hobbes A company's most valuable asset is the conversation it has with a buyer. Most B2B websites lose that conversation at the "request a demo" form. Hobbes runs real, conversational product demos 24/7. That's Phase 1. The real bet is a self-improving agentic layer that runs the revenue side of a business. Every conversation a prospect has with the agent is logged, measured, and fed back into the product. Five prospects tell Hobbes they want to buy but need Hubspot integrated as a non-starter? Hobbes creates the PR autonomously and updates those prospects that it's ready to go-live. We have secured $6M in funding and have tripled since February, mostly on inbound. One customer 2x'd their revenue within 8 weeks of deploying Hobbes. Another closed a deal within 2-hours of Hobbes going live on their site. ## What you'll build - The agent. LLM orchestration, conversation flow, tool use, voice. - Generative UI that adapts in real time to what the prospect cares about. - The eval loop. Demos get smarter without manual intervention. - The platform customers use to configure, review, and tune their agent. - And yes: CSS, migration scripts, customer debugging. Early-stage means all of it. ## What we're looking for - You've shipped LLM systems to production and can talk about what broke and what you did about it. - You move fast without creating hidden problems. You've also killed features that weren't working. - You take ownership without being asked. ## Comp - **Base:** $180-230K - **Equity:** Founding-caliber - **Location:** In-person, San Francisco ## Process 4 rounds: Arjun, Chirag, async case study, paid 3-day work trial in the office. About 2 weeks from first conversation to offer.
