Founding AI Engineer

ABOUT THE ROLE

Join an early-stage B2B SaaS team as its founding AI engineer, building the core of a real-time voice agent that supports sales conversations and product demos. You will own the agent's technical direction, from architecture and model choices to measuring and improving performance.

WHAT YOU'LL DO

• Build agent reasoning, tool use, memory, and recovery for live conversations, while meeting tight latency requirements.
• Develop evaluation pipelines and use call data to drive measurable improvements, including fine-tuning where it is effective.
• Improve the reliability of browser automation so the agent can demonstrate products in a live browser while speaking with buyers.
• Ship product features end to end using TypeScript, Node.js, and Next.js.
• Work with customers and design partners to shape the product, and set direction on models, methods, and build-versus-buy decisions.

WHAT WE'RE LOOKING FOR

• Four to seven years of AI engineering experience, including hands-on experience shipping AI agents in production from end to end.
• At least one year working with real-time or voice AI systems, such as WebRTC, LiveKit, streaming, or other low-latency applications.
• Experience with agent evaluation, observability, and cost optimization, plus TypeScript, Node.js, and Next.js.
• Background in voice AI, AI sales, browser agents, sales technology, or another fast-growing AI product environment.
• Experience with browser automation tools such as Playwright and working directly with customers or design partners is valuable.
• A computer science degree or another technical background, with strong technical fundamentals.
