At CSGPT, we’re building the future of Agentic AI — systems that don’t just answer questions, but take action. Think: tools that orchestrate workflows, make decisions, and get things done — autonomously.

To make that possible, we’re building out our backend and AI infrastructure. We process data, connect to APIs, train small models, and build smart agents that users can trust.

We already have first customers who we were able to learn a ton from and now we are scaling so we need a Backend/AI Engineer to help us push this vision forward.

What you'll work on:

• Shape how our AI agents make decisions and take actions in the real world
• Ship fast, test with users, and iterate
• Work on small model training and evaluation
• Build and maintain our backend systems (Node.js + Firebase, PostgreSQL)
• Integrate LLMs into smart workflows

We’re a small team — so this isn’t a narrow, “just write the endpoints” type of job. You’ll touch product logic, AI capabilities, and system architecture.

The stack:

• Node.js, Firebase (Functions, Firestore, Auth)
• Python (for AI logic and integrations)
• PostgreSQL
• GCP
• Git workflows
• Bonus: Make.com, Zapier, or n8n
• Extra bonus: you've already built your own AI agents

Who we’re looking for:

• You write clean, maintainable backend code and you know how to test it
• You understand that requirements sometimes shift fast in a startup and are okay with a bit of ambiguity (you don't just follow requirements)
• AND most of all - you genuinely love building AI products and do it because it's fun, not just because it's your job

What you can expect from us:

• A product-first, async-first culture
• Full remote flexibility and minimal meetings
• Room to try bold ideas and fail safely
• Competitive salary, based on your experience
• A fast-growing area where you’ll learn a lot, quickly

This role isn’t a good fit if:

• You prefer clear, unchanging specs over exploratory work
• You need tight day-to-day management or don’t like async work
• You’re early in your career — we love mentoring, but need someone experienced at this stage

If that sounds like your role - apply to this job and we'd be happy to have a chat and get to know you!
