Senior Fullstack Developer (Node.js)

As a Senior Full Stack Engineer, you'll contribute to building reliable, scalable solutions for our product, Tellent HR. You will shape technical architecture, make key decisions, and promote best engineering practices to ensure high-quality, maintainable code across the full stack.

While your main focus will be on developing backend modules, you’ll have the opportunity to influence frontend features and user experience, working closely with designers and frontend developers. You'll take ownership of critical components, guiding their evolution as the product scales. In addition, you'll mentor team members through code reviews and pair programming, support cross-functional collaboration, and help ensure smooth integration of new features. Your strategic technical input will align system design with business goals, while your hands-on approach will help drive the ongoing improvement of our platform.
