**Description**:
We’re looking for a Brazil-based Full Stack Developer (solo or a small team) who can take ownership of delivery, maintenance, and continuous iteration. You’ll work directly with the founder, under NDA, with a long-term collaboration mindset.
**Responsibilities**:
- Design and implement APIs, business logic, and database structure
- Create and maintain admin panels for frequent data entry and updates
- Implement user authentication, roles, and permissions
- Improve performance, reliability, and scalability as the product grows
- Maintain the existing system: bug fixes, refactors, upgrades, and new features
- Propose practical technical improvements (architecture, tooling, security, DX)
- Communicate clearly: progress updates, tradeoffs, and realistic timelines
What This Is NOT
- Not a WordPress site
- Not a short-term freelance gig
- Not a design-only role
**Requirements**:
- Based in Brazil (mandatory)
- Strong experience with both frontend and backend development
- Comfortable working on long-term projects, not one-off builds
- Able to maintain, improve, and scale an existing system
- Willing to work under NDA
**Nice to have**:
- Experience with SaaS or internal platforms
- Experience owning projects end-to-end
- Ability to suggest architecture and process improvements
- Familiarity with secure development practices (auth, data protection, auditability)
**Benefits**:
- Long-term collaboration (not a short gig)
- Direct access to decision-making (work with the founder, fast feedback loops)
- Flexible engagement model:
- monthly retainer, or
- phased delivery (milestones) with ongoing maintenance
- Opportunity to shape a real system and improve it continuously
