Software Engineer - Backend & AI Agents

\ _Before you apply \_ Don't use Chat GPT to write this. Spelling mistakes are fine. Generic AI writing is not — we can tell, and we'll skip you. Show us how you think. \ _What we're building \_ Everyone will have their own AI agent. A doctor. A gym owner. A designer. A store. Their own agent, in their voice, on every channel their customers use. 91agents is how they get there. \ _The role \_ You work directly with the founder from day one. You sit inside product decisions. You own what you ship. This is not a role where you wait for tickets. We'll hand you a problem and expect you to run with it. We also expect you to say "I'm stuck" the moment you are. Contract to start. Prove yourself, and it becomes full-time with equity. \ _You should have \_

• Touched LLM finetuning. Lo RA, QLo RA, or a full run — even a small one. You know when finetuning is worth it and when a good prompt is enough. We don't need you finetuning every day. We need to know you're past the tutorial stage.
• Shipped at least one real AI agent. Not a demo. Not a hackathon. Something that ran, had users, and broke in production. We want to hear about the breakage.
• Built with context engineering, memory, and tools. You know when to use multiple agents and when one good agent with good tools does the job. 4. Strong in Node.js + Type Script OR Python + Fast API. Comfortable in the other. Postgres and Docker are basics. 5. Shipped one payment gateway end-to-end. Stripe, Razorpay, Cashfree, or Lemon Squeezy. Webhooks, idempotency, reconciliation — the boring parts. 6. Fluent with Claude Code, Codex, Cursor, or Windsurf. You ship 3x faster because of them.

\ _Bonus \_

• You've built evals, debugged agents, or written prompt regression tests. You've worked with RAG or retrieval at real scale.
• You run a side project that people actually use.

Not for you if

You need a ticket to start. You want stability over growth. You've never shipped an agent. You go silent for days (weekends off is fine — silence is not). \ _For you if \_ You've shipped something real with AI agents and want to do it ten more times this year. You get energy from building, not meetings. You think about what to build even when nobody asked. You want to join something from day one, not after it's figured out. \ _How to apply \_ Email hello@91agents.dev with subject: "I build agents" Send three things: One agent you shipped. What it does. How you built it. What broke, and what you did about it. Your Git Hub or anything live. Links, not PDFs. One thing you'd build or fix on 91agents.dev right now — be specific, and give us one sentence on why. That's it. No CV. No cover letter. Just the work.
