Hiring elite Python talent across Engineering, Data, AI & ML for New England tech companies l Founder l Vice President, USA | Tech Podcast Host I 20+

A stealthy, high-growth YC startup at the frontier of applied LLMs and conversational AI is hiring a talented Full-Stack Engineer to help power the next trillion voice interactions. Theyve already deployed AI agents that resolve over a million support tickets monthly, and thats just for one early client.

Backed by a recent Series A raise (at a strong 9-figure valuation) and with multi-year contracts signed across crypto, food delivery, and other high-volume industries, theyre rapidly becoming a go-to partner for elite AI-driven customer support.

This is an opportunity to work closely with a tight-knit team of world-class engineers, ship real product fast, and help define how AI transforms enterprise support, without endless layers of process or bureaucracy.

Why This Role?

  • Impact from Day 1 - Youll contribute directly to systems used by some of the most recognizable consumer brands.
  • Real Ownership - Your work will shape architecture, product direction, and performance at scale.
  • Fast-Paced Growth - Theyre backed by YC and top-tier VCs.
  • Top-Tier Colleagues - Collaborate with engineers and founders from elite technical and entrepreneurial backgrounds.

What Were Looking For

  • 35 years of full-time software engineering experience
  • Strong Python backend skills (Django is a plus)
  • Solid frontend experience with React, Next.js, and ShadCN
  • Hands-on experience with AWS or GCP
  • A CS degree from a top-tier university (especially valuable with lighter experience)
  • An entrepreneurial streak, bonus if you've worked at or founded a startup
  • Grit and productivity - you enjoy working hard, iterating quickly, and delivering independently

Green Flags

  • Experience with LLM agents, AI tooling, or other applied ML products
  • Previous startup or early-stage company experience
  • GitHub full of independent, shipped full-stack projects
  • Familiarity with Docker, Kubernetes, or scalable cloud infrastructure

What Youll Get

  • Lifestyle Perks: Full medical/dental/vision, wellness stipend, Equinox membership, daily meals/snacks/coffee
  • Visa Support: H-1B, O-1, and OPT candidates welcome
  • Environment: Fast, lean, hands-on, and ambitious, with a real shot at changing the landscape of enterprise AI

If youre an engineer whos hungry to move fast, ship serious product, and leave your mark on a fast-scaling, AI-native company, this is your chance. Apply now to join a team thats building the future, one intelligent conversation at a time.
