About the Role

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

What You'll Do

Build the agent's reasoning, tool use, and memory, including ways to recover when live conversations go off script while meeting real-time latency requirements.

Develop evaluation pipelines and work with sales-call data to drive measurable improvements, including fine-tuning where it is effective.

Improve the reliability of browser automation so the agent can deliver live product demonstrations while speaking with prospective customers.

Ship end-to-end product features using TypeScript, Node.js, and Next.js.

Work directly with customers and design partners to shape product development.

Set technical direction for models and methods, and decide what to build, buy, and develop next.

What We're Looking For

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

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

At least one year working with real-time voice systems, such as WebRTC or LiveKit, or browser agents using tools such as Playwright.

Proficiency in TypeScript, Node.js, and Next.js, along with experience using LLM APIs and browser automation.

Background in voice AI, AI sales, browser agents, or other fast-growing AI products; experience with sales technology or go-to-market tools is useful.

Experience working directly with customers or design partners in an engineering role.
