- Develop evaluation pipelines and data workflows that turn real sales conversations into measurable improvements, and fine-tune models where useful.
- Improve the reliability of browser-based product demonstrations conducted during live calls.
- Ship end-to-end product work using TypeScript, Node.js, and Next.js, working directly with customers and design partners.
- Set technical direction for model and tooling choices, architecture, and future agent 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 production agent with real users or meaningful usage.
- End-to-end experience shipping production AI agents, including evaluation, observability, and cost optimization.
- At least one year working with real-time voice technologies such as WebRTC, LiveKit, or streaming systems, or browser agents using tools such as Playwright.
- Proficiency in TypeScript, Node.js, and Next.js, with experience using LLM APIs and browser automation.
- Background in voice AI, AI sales, browser agents, or fast-growing AI companies; experience with reinfo
