About the role

About the Role

Join an early-stage SaaS team as its fifth engineer and own the technical direction of a production AI voice agent for sales. The agent participates in live customer calls, conducts product demonstrations through browser control, and follows up with prospects.

What You'll Do

  • Build agent reasoning, tool use, and memory, including recovery when live calls go off script while meeting real-time latency requirements.
  • Develop evaluation pipelines and data workflows that turn sales-call data into measurable improvements, and fine-tune models where useful.
  • Improve the reliability of browser-based product demonstrations while the agent speaks with buyers.
  • Ship end-to-end product work using TypeScript, Node.js, and Next.js, collaborating directly with customers and design partners.
  • Set the agent's technical direction, including model and tooling choices, build-versus-buy decisions, and future capabilities.

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 with real users or meaningful usage.
  • Experience shipping agents end to end, including evaluation, observability, and cost optimization.
  • Hands-on experience in voice AI, AI sales, browser agents, or a fast-growing AI company, with at least one year working on real-time voice or browser agents.
  • Proficiency in TypeScript, Node.js, and Next.js, plus experience with LLM APIs, WebRTC, LiveKit, Playwright, browser automation, evaluations, fine-tuning, or reinforcement learning.
  • A computer science degree or another technical background, such as mathematics, physics, or engineering.
  • Experience working directly with customers or design partners is valuable, as are startup founding experience and background in sales technology or go-to-market tools.

Base salary: $200,000 to $250,000 annually. Visa sponsorship is available.
