About the Role
Join an early-stage B2B SaaS team as its founding AI engineer, building the core of a real-time voice agent that conducts sales conversations, demonstrates products in a browser, and follows up with prospects. You will lead the agent's technical direction and help shape its next capabilities.
What You'll Do
- Build the agent's reasoning, tool use, memory, and ability to recover when live conversations go off script while meeting strict latency requirements.
- Develop evaluation pipelines and use real sales-call data to drive measurable improvements, including fine-tuning 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.
- Work directly with customers and design partners to shape the product and guide decisions about models, architecture, and build-versus-buy tradeoffs.
What We're Looking For
- Four to seven years of experience as an AI engineer, including at least one year working with real-time or voice AI systems.
- Experience shipping AI agents to production and owning the workflow, including evaluations, observability, and cost optimization.
- Hands-on experience with voice AI, real-time applications, browser automation, or AI sales products.
- Proficiency in TypeScript, Node.js, and Next.js; familiarity with WebRTC, LiveKit, Playwright, LLM APIs, and agent evaluation methods is relevant.
- A CS degree or another technical background, such as mathematics, physics, or engineering.
- Customer-facing engineering, design partner collaboration, sales technology, or startup experience is valuable.
