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
