• MariaDB: Housing our user and translation data.
• CloudFlare: Our layer for DNS management, Workers, CDN, and more.

• Document processes and features as you learn and build
• Share ideas and propose technical improvements to our stack.

A typical day at Sitly

It’s Thursday, one of the two days you work from the office. You arrive at our office at the Rokin just across the metro station in the centre of Amsterdam. You grab a coffee before the team stand-up begins. Some of your teammates join remotely, while others are there in person. You share what you’ve been working on and sync on priorities for the week. You’re currently building a new API feature to improve sitter-parent communication, and you plan to pair up later with your onboarding buddy, our API specialist, for feedback on your implementation.

After the stand-up, you catch up with the product owner and team lead, who also work from the office a couple of days a week. Together, you review an upcoming feature and share your ideas on how to prioritise a few technical improvements. You bring your own perspective on how to enhance the platform. Your suggestions are well received and included in the implementation.

Around noon, a couple of colleagues put together one of their legendary shared lunches, something they enjoy doing for the team. You all take your time to connect over food and laughter, sometimes heading up to the rooftop terrace for a coffee and some fresh air.

In the afternoon, you continue working on your feature, write tests, and pick up a code review request from a remote teammate.

Required skills

• Seasoned full-stack developer with experience delivering features end to end.
• Expert in Node.js, with strong knowledge of Express, TypeScript, and backend architecture.
• Proactive: you take initiative, suggest improvements, prioritise, and take ownership.
• Strong grasp of clean code, best practices, and scalable systems.
• Solid experience with SQL and Git workflows.
• Fluent in HTML, CSS, JavaScript, and familiar with CSS preprocessors.
• Experience with an SPA framework (Angular, React, or Vue). Angular is a plus, not a must.
• Bonus: experience with AWS, Cloudflare, ELK stack or Jenkins.
• Fluent in English, written and spoken.
