Respaid (YC S23) builds AI agents that recover unpaid invoices for enterprise clients. Hundreds of thousands of AI-powered calls and emails sent. 460 customers, profitable, growing.
This is not a normal engineering job. And this is not a normal hiring process.
WHY THIS ROLE IS DIFFERENT
We are an AI-native team. Every engineer uses Claude Code, MCP servers, custom skills, and automated QA pipelines daily. Our CLAUDE.md file is 500+ lines of conventions, and our CI runs AI-powered code review on every PR.
You won't just use AI tools. You'll help build the infrastructure that makes the entire team 10x faster.
Stack: Laravel 12 (PHP 8.4), MySQL, Redis, Laravel Nova, RetellAI voice agents, Telnyx, Stripe, SendGrid. AWS Elastic Beanstalk.
NO INTERVIEWS. NO TAKE-HOME ASSIGNMENTS.
Our hiring process IS our dev environment:
- Fork github.com/wwwidr/hiring-challenge
- Read the CLAUDE.md
- Pick a ticket from /tickets
- Ship a PR with tests, following the repo's conventions
- Screen-record your entire session
- AI reviews your PR automatically. Score >= 8/10 = you talk to the CEO.
No leetcode. No whiteboard. We watch your screen recording and read your code.
