- 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.
