Founding AI Engineer
Confirmed on the employer's own hiring board on Oct 29, 2026. First seen by Alion on Oct 28, 2026.
About the Role
Join an early-stage B2B SaaS team as its fifth engineer and lead the technical direction of a real-time AI voice agent for sales. The agent participates in live customer calls, demonstrates products through browser interactions, and follows up with prospects.
What You'll Do
Build the agent's reasoning, tool use, memory, and ability to recover when live conversations go off script, while meeting real-time latency requirements.
Develop evaluation pipelines and use call data to drive measurable improvements, including fine-tuning where it is effective.
Improve browser automation reliability so the agent can demonstrate products in a live browser while speaking with buyers.
Ship product features end to end using TypeScript, Node.js, and Next.js, working directly with customers and design partners.
Set technical direction for model and method selection, build-versus-buy decisions, and future agent capabilities.
What We're Looking For
Four to seven years of AI engineering experience, including hands-on experience shipping AI agents end to end in production.
At least one year working with real-time or voice AI systems, such as WebRTC, LiveKit, streaming, or other low-latency applications.
Experience with voice AI, AI sales, browser agents, or another fast-growing AI product, plus familiarity with agent evaluation, observability, and cost optimization.
Proficiency in TypeScript, Node.js, and Next.js, with experience in browser automation tools such as Playwright.
A computer science degree or another technical background, with strong software engineering fundamentals.
Startup founder or founding engineer experience is relevant.
Must be based in New York or able to relocate there from the first day.
