Senior Full-Stack Developer

We are hiring a Senior Full-Stack Engineer to join an existing, production-grade platform that is actively evolving and scaling.

This is not a greenfield project — you will be working on a live system with real users, focusing on improving scalability, performance, and architecture while continuing to build new features.

We are looking for someone who thinks beyond code — a developer who understands systems, trade-offs, and long-term maintainability.

• Work on a mature codebase, improving structure, scalability, and performance
• Design and implement backend services using NestJS (Node.js, TypeScript)
• Build and optimise frontend features using Next.js (React)
• Refactor and enhance existing components to meet growing product demands
• Contribute to system architecture decisions and technical direction
• Ensure high standards for code quality, testing, and reliability
• Collaborate closely with product and leadership on feature evolution

• 5+ years of experience building production systems
• Strong expertise in Node.js, TypeScript, and backend architecture
• Hands-on experience with NestJS in real-world, scalable applications
• Solid experience with Next.js / React in production environments
• Experience working on existing, complex systems (not just greenfield projects)
• Ability to take ownership and make technical decisions
• Clear communication and strong English

• Experience scaling products (performance, load, architecture evolution)
• Familiarity with microservices or modular architectures
• AWS Cloud experience
• Experience working in fast-paced, product-driven environments

• Remote-first environment (Portugal-based)
• High ownership and impact on a scaling product
• Direct involvement in technical decisions
• A team focused on building, not bureaucracy
