Founding AI Engineer
Confirmed on the employer's own hiring board on Nov 2, 2026. First seen by Alion on Nov 1, 2026.
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.
