Work with customers and design partners to shape the product, and set direction on models, methods, and build-versus-buy decisions.
What We're Looking For
Four to seven years of AI engineering experience, including hands-on experience shipping AI agents in production from end to end.
At least one year working with real-time or voice AI systems, such as WebRTC, LiveKit, streaming, or other low-latency applications.
Experience with agent evaluation, observability, and cost optimization, plus TypeScript, Node.js, and Next.js.
Background in voice AI, AI sales, browser agents, sales technology, or another fast-growing AI product environment.
Experience with browser automation tools such as Playwright and working directly with customers or design partners is valuable.
A computer science degree or another technical background, with strong technical fundamentals.
