Senior Full-Stack Developer

About the Role

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, where your focus will be 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.

What You’ll Do

• 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

What We’re Looking For

• 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

Nice to Have

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

What We Offer

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