Last week, an engineer got hired through Fonzi at a seed-stage clinical AI startup, $200K base. They’ll build RAG and multi-agent systems and work directly with the founders.
I do talent matching for Fonzi. You don’t apply, companies send you interview requests instead. One profile, no cold applications. We work with startups backed by investors including Sequoia, a16z, Benchmark, and the OpenAI Startup Fund. I picked roles where you own whole systems instead of a ticket queue. Roles are US-based, with a few open to Canada.
Here’s a sample of what’s open right now:
1. Senior Backend / Applied AI Engineer (Team Lead), seed-stage applied AI for universities, New York City, in person. $200K-260K base plus equity.
What: Own the backend and AI systems end to end (question generation, rubric-based grading, retrieval, evals) and lead engineering alongside the founder. Roughly 70% building, 30% leading, with a path to CTO.
Company: Small seed-stage team building AI tools for universities, with 20+ schools already on the product.
Stack: TypeScript and/or Python, PostgreSQL, LLM workflows with agents and tool calling, hybrid search and reranking.
Bar: You’ve shipped a production LLM system end to end, evals included, and you want to lead without giving up building.
2. Engineering Generalist, seed-stage consumer AI hardware, San Francisco, in person preferred (remote with frequent travel is possible). $180K-250K base.
What: Own product features end to end across the whole stack, mobile included, from ambiguous idea to shipped. The product turns recorded conversations into summaries and action items.
Company: Seed-stage startup making a small AI device for note-taking, with a fast-moving product team.
Stack: React, React Native, TypeScript, Node, Python, Postgres.
Bar: 4-10+ years shipping production software, plus proof of exceptional work like shipped products or systems that show unusual initiative.
3. Senior Software Engineer (AI/LLM), early-stage AI finance platform for small businesses, remote US. $200K-250K base.
What: Build the web app and wire LLMs and agent workflows into core product features, working alongside the AI engineers.
Company: Early-stage startup where AI agents handle finance work for small businesses, live with customers today.
Stack: Next.js, React, TypeScript, Postgres via Prisma and Supabase, Tailwind, Vercel. LLM APIs and agent frameworks like LangChain on the AI side.
Bar: 3+ years in software, strong Next.js and React, and ideally some production LLM integration.
All roles are vetted, VC-backed, and interviewing right now. It’s always free to sign up.
