JOB OVERVIEW

We are a SaaS company (influencer marketing platform, real paying customers) looking for ONE strong developer to become our long-term technical owner. This is a stable, full-time, direct position - not project-based.

IMPORTANT - READ BEFORE APPLYING: Our codebase was built fast using AI tools (Lovable) and has real technical debt: 266K lines of code, 274 backend edge functions with duplication, 554 database migrations, 4,300-line React components, no tests, TypeScript strict mode disabled. Your first months will be untangling and stabilizing this - not building shiny new features. If that excites you, keep reading. If you only enjoy greenfield projects, this is not for you.

YOUR RESPONSIBILITIES:
- Refactor large components into maintainable modules
- Consolidate duplicated Supabase edge functions
- Gradually enable TypeScript strict mode and fix what surfaces
- Add automated tests to critical flows (payments, contracts, WhatsApp webhooks)
- Fix recurring bugs at the root cause, not the symptom
- Use Claude Code / Codex daily to move fast - but with real engineering judgment behind it

REQUIREMENTS:
- Solid professional development experience with real production systems (not only AI-generated projects)
- Strong React + TypeScript, strong PostgreSQL
- Real experience inheriting and cleaning up messy production codebases
- Excellent written English, reliable internet, able to work independently
- Experience with Supabase (or Firebase + willingness to learn fast)
- 3-4 hours daily overlap with Israel time (GMT+3)

HOW TO APPLY - VIA WHATSAPP ONLY:
Click to message us on WhatsApp: ----------
1. Start your message with the word REFACTOR so we know you read this
2. Include a link to a project where you inherited messy code and improved it - tell us what you found and fixed
3. One paragraph: how would you safely break down a 4,300-line React component without freezing development?

Messages missing any of these three will not be answered. Our screening assistant will ask you a few technical questions first - answer them seriously, they d ---------- who gets an interview.

HIRING PROCESS: WhatsApp screening -> short interview -> paid test task (3-5 hours, we pay $50) -> full-time offer.

COMPENSATION: $750/month full-time. Long-term stable role with an owner who invests in you.
