Full Stack or Backend GenAI Developer – AI Coding Product
.
VibeLevel.ai is an AI-native technical assessment platform redefining how engineering talent is evaluated. We measure how developers collaborate with AI — not just whether they can code — using real IDE-based assessments, and multi-dimension evaluation. We're an early-stage founding team building a global product.
We can offer a founding-team seat on a global AI product and a genuine path to Co-Founder or CTO with equity. If you're optimizing for learning, ownership, and long-term upside over short-term pay, we would like to you to explore this.
We're looking for a mid-level full stack or backend engineer with a product mindset and genuine fire for building AI-native systems. You'll work directly with the founding team, own features end-to-end, and use AI coding tools — Claude Code, GitHub Copilot — as a core part of how you work, not an afterthought. If you want to ship a global AI product and grow into a technical leadership role, read on.
• Design and build scalable agentic REST APIs and background processing pipelines
• Extend our LLM-based scoring engine — multi-dimension candidate evaluation, structured outputs, streaming
• Build async task processing — scoring pipelines, resume analysis, webhook handlers
• Work with cloud storage, session persistence, and PostgreSQL at scale
• Collaborate on LangChain / LangGraph multi-agent workflows
• Write clean, well-tested, observable code with proper logging and error handling
• Use Claude Code and GitHub Copilot as expert AI collaborators to deliver fast, reliable, production-grade code
• 1–3 years of backend development experience (mandatory)
• LangChain and multi-agent AI systems experience deployed to Production
• Strong Python — FastAPI, async/await, Pydantic
• PostgreSQL — Building scalable and schema evoluation/fleaxbile data model design experience
• Expertise with LLM SDK's — prompt engineering, func tool calling, context management, structured outputs, chat session mgt
• CloudFare, Vercel, Fly.io, Docker, CI/CD
• Proficient with AI coding assistants (Claude Code, GitHub Copilot, Cursor) in daily workflow
• Full stack experience — Next.js or modern frontend frameworks (React, TypeScript)
• SaaS billing / subscription systems (Stripe, Paddle)
• Background in EdTech, HRTech, or developer tools
Apply at https://www.vibelevel.ai/apply/5LmRgicc
If your application is shortlisted you will be invited to complete a live coding assessment using an AI assistant — we evaluate how you collaborate with AI, not just the output.
You get only 1 attempt for the live coding assessment so familiarize with the platform we are providing a similar challenge to practice first here https://www.vibelevel.ai/practice/236bab3f
