Founding AI Engineer

Job description

ABOUT THE ROLE

Join an early-stage B2B SaaS team building a real-time AI voice agent for sales conversations. You will lead the agent's technical direction and help develop a product that joins live calls, runs browser-based demos, and follows up with prospects.

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 low-latency requirements. - Create evaluation pipelines and work with call data to measure and improve agent performance, using fine-tuning where useful. - Improve the reliability of browser-based product demos conducted during live sales conversations. - Ship product features end to end with 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 or buy.

WHAT WE'RE LOOKING FOR - Typically 4 to 7 years of AI engineering experience, with a technical degree or equivalent background in a field such as math, physics, or engineering. - Hands-on experience shipping AI agents in production and owning their lifecycle, including evaluations, observability, and cost optimization. - At least one year of experience with real-time or voice AI systems, such as WebRTC, LiveKit, or streaming applications. - Experience with TypeScript, Node.js, and Next.js, plus browser automation tools such as Playwright. - Background in voice AI, AI sales, browser agents, sales technology, or customer-facing engineering at a startup or other fast-growing technology company.
