Next.js Engineer (AI-driven)

QIT Software is looking for a top-tier full-stack developer ( PART TIME)  to help us finish what we started. This is not an entry-level role. We're at 80% MVP completion with most UI and flows already designed. We need someone experienced who can quickly onboard, understand complex systems, and execute without babysitting.

You'll work directly with the founder of a fast-moving marketing tech startup. The platform is AI-driven and built to automate complex marketing workflows. If you know how to own a full-stack project and think through the “why” behind every workflow, this is for you.

Requirements: 
- 5+ years full-stack experience
- Pro in Next.js, React, Tailwind, PostgreSQL, Supabase
- Experience with real-world APIs (auth flows, webhooks, token refresh, etc.)
- Familiarity with AI integrations like OpenAI or Claude
- Can work independently and solve problems without constant guidance
- Excellent spoken and written English
- Reliable and responsive during business hours

Responsibilities:
- Build full-stack features using Next.js, React, Supabase
- Write and manage complex PostgreSQL queries and functions
- Implement and troubleshoot Edge Functions, triggers, background jobs
- Integrate with APIs (OpenAI, Claude, Meta, Google Ads, Stripe)
- Work from existing UI/UX and workflows, and fill in the logic gaps
- Own everything from backend logic to clean frontend UI
- Understand user experience and build with the final user in mind

We offer (After switching to the full-time):
- Revision of wages every year or on an individual basis;
- Accounting support and full payment of taxes by the company;
- 100% compensation for remote English lessons;
- 15 paid leaves (PTO) and public holidays.
