Founding Senior Software Engineer - Voice AI $125K - $175K + 0.50% – 1.00% equity New York City (in-person preferred) We're partnering with a fast-growing voice AI startup that's redefining how frontline teams are trained and supported in real-time. Since launch earlier this year, they’ve landed 4 of the top 10 auto insurers in North America and are already training thousands of claims adjusters through intelligent, interactive voice simulations. This is an opportunity to join as one of the first engineers and take full ownership across the stack - from building agentic voice AI systems to designing new customer-facing features that rethink how enterprises onboard and empower their people. What you’ll do: Build features end-to-end across frontend, backend, infra, and database layers Own and refine LLM prompts, agent logic, and AI tooling Work directly with enterprise customers—from onboarding to post-sales iteration Research advancements in voice AI (LLMs, STT, TTS, etc.) and ship prototypes that move the needle Collaborate closely with the founders on product roadmap, GTM support, and hiring You’ll thrive here if you: Have 3+ years’ experience building full-stack products from scratch Enjoy ownership and autonomy - you'll lead initiatives from 0 to 1 Are excited about experimenting with new LLM-driven UX patterns and workflows Have experience (or strong curiosity) working with tools like WebSockets, WebRTC, real-time voice streaming, or similar Are product-minded and love building for real users Bonus: Have startup/founder experience, or have built/used LLMs in production Interview Process: 30-min intro call

- you’ll work on a live, scoped project with the team. Ideally in-person (NYC), but remote options are possible too. Decision made within 24 hours post-trial. Why this role? If you're looking to accelerate your career by 3-4 years in one move, this is it. You’ll be a core contributor shaping the product, the tech, and the team - while building things that make an immediate, measurable impact. Want to learn more or apply?
