Full Stack Developer for B2B SaaS
Budget: $8 – $15 USD
We are looking for a Full Stack Developer to collaborate on the ongoing development of a B2B SaaS product focused on the U.S. market.
The product already has a real technical foundation and active development. It is not a greenfield project or a simple MVP, but it is still in a growth and refinement phase. We need someone comfortable working with an existing codebase, respecting architectural decisions, and helping evolve the system.
Scope of work
• Develop new frontend and backend features
• Work within a modular, multi-tenant architecture
• Handle permissions, roles, and real SaaS business logic
• Implement features with practical use of AI (automation, assistance, analysis, productivity)
• Improve performance, UX, and code quality when needed
Main stack
• React + TypeScript
• Full stack mindset (frontend-leaning is fine)
• API design and consumption
• Tailwind CSS or similar approach
AI experience (important)
• Hands-on experience using AI in real products
• Integration with AI APIs for automation or intelligent features
• Understanding of cost, limitations, and production impact of AI
Nice to have
• Experience with B2B SaaS products
• Multi-tenant systems
• Billing or payment systems (e.g. Stripe)
• PostgreSQL and/or Supabase
This is a remote collaboration with flexible hours, focused on ownership, responsibility, and long-term collaboration rather than one-off tasks.
