As a Senior Front-end Developer, you play a key role in shaping the user experience of our platform. You’ll build intuitive interfaces that make daily work smoother for planners, operators, drivers, and office teams. You turn ideas into fast, friendly screens, and you help guide the technical direction of our front-end.

You’ll work closely with designers, back-end developers, and product owners to create features that feel natural to use. You understand how to balance functionality with simplicity and you enjoy improving both.

Importantly, you’ll focus exclusively on new front-end development. You won’t be required to maintain or work on legacy software, giving you the space to build modern, forward-looking solutions using up-to-date technologies and best practices.

You’re comfortable taking ownership, making decisions, and helping others grow. You have experience with modern frameworks and know how to write clean, maintainable code. You think ahead, spot problems early, and enjoy shaping a product that thousands of people rely on every day.

Most importantly, you like working with people. You share your knowledge, ask questions, and enjoy solving things together.

You’ll join a multidisciplinary product team where collaboration is the norm. You work alongside designers who care about user experience, back-end developers who build the solid foundation behind our platform, and product owners who keep everything clear and focused.

The atmosphere is open and informal: we share ideas early, ask questions freely, and discuss solutions together. You’ll have a big influence on the front-end direction, but you’ll never have to do it alone, the team is experienced, supportive, and always ready to help each other move forward.

We work with short communication lines, quick decisions, and plenty of freedom to try new approaches. It’s a place where your ideas matter and where you can genuinely shape the product.

You don’t need to tick every box perfectly, but these are the skills and experiences that will help you feel confident and effective in this role.
