Founding AI Engineer

About the Role

Join an early-stage SaaS team as its founding AI engineer, building the core of a real-time AI voice agent for sales. You will own the agent's technical direction and help turn customer conversations into a dependable product.

What You'll Do

• Build the agent's reasoning, tool use, and memory, including its ability to recover when live conversations go off script while meeting latency requirements.

• Develop evaluation pipelines and data workflows that use real sales conversations to measure and improve agent performance, including fine-tuning where useful.

• Improve the reliability of browser automation so the agent can demonstrate products in a live browser while speaking with buyers.

• Ship end-to-end product work with TypeScript, Node.js, and Next.js, collaborating directly with customers and design partners.

• Set technical direction for model and tooling choices, and define the agent's next capabilities.

What We're Looking For

• Four to seven years of experience as an AI engineer, including at least one year owning a user-facing AI agent in production.

• Experience shipping agents end to end, including evaluation, observability, and cost optimization.

• At least one year working with real-time voice technologies such as WebRTC or LiveKit, or browser agents and automation such as Playwright.

• Proficiency in TypeScript, Node.js, and Next.js, with experience using LLM APIs and AI agent systems.

• Background in voice AI, AI sales, browser agents, or a fast-growing AI company; sales technology or go-to-market tooling experience is useful.

• Experience building with customers or design partners and a track record of sustained tenure in recent roles.
