Full Stack Engineer (Preferred Backend Focus) - AI SE SaaS

We're looking for a FULL STACK ENGINEER - for building a AI SEO Workflows tool.

We've bootstrapped the agency too $2M ARR in 2 years, now we're building a competitor too AirOps.com .

There are already 5X full time people on the SaaS.

This SaaS will be a COMPLEX SEO/AEO workflows tool such as:

• Content Creation
• Internal Linking
• On Page SEO
• Reddit 
• ...etc

Think of a similar tool to AirOps but 10X better that actually works.

You'll work in tandem with our CTO and another full stack engineer.

This is not a no-code role.

We are not looking for Zapier-only, Make-only, Bubble-only, or "AI chatbot" builders. We are looking for someone who can build proper software solutions using code, APIs, databases, backend functions, and secure deployment practices.

Our core stack is Supabase, Vercel, TypeScript/JavaScript, Node.js, APIs, serverless functions, and modern frontend frameworks.

This is a full time role, if you are freelance and an amazing person, we would still consider but we are looking for full time ideally!
