Find jobs that fit your situation.

• You’ll have the unique opportunity to build a backend that serves millions of passengers every day.
• You’ll join a forward-thinking DevOps team where you have the freedom to contribute ideas and experiment with new technologies.
• Our teams have end-to-end responsibility for the entire process: from discovery, user research and design to development and continuous improvement. As teams, we also run and host our own backends: “You build it, you run it, you love it.”

You’ll work from our head office near Utrecht Central Station as well as from home, as part of a multidisciplinary DevOps team. You’ll work alongside another Backend Developer, an iOS Developer and an Android Developer. The team also includes a UX/UI Designer, Scrum Master and Product Owner.

Within the Service domain, there is extensive collaboration with other teams, for example teams that maintain services for the Forgotten Check-out process and teams working on the JeNS chatbot.

Together, we brainstorm innovative solutions, collaborate closely and explore new possibilities both within and beyond our own areas of expertise. And, of course, you’ll spend plenty of time doing what you enjoy most: developing. We support you with the latest technologies.

Our team is one of seven teams jointly responsible for components of the NS app. Backend Developers meet every week to present their work and discuss improvements that benefit multiple teams. These meetings give you the opportunity to make an impact and help shape our technical direction.

Our developer culture values everyone’s input. Nothing is “set in stone.”

Our backend currently consists of serverless applications deployed on AWS. We are actively working towards stateless front-end applications by using a BFF (Backend for Frontend) architecture.

There is also a strong demand for an app that can adapt to passengers as they travel. To achieve this, we use applications outside our own team for content and personalisation. A versatile backend is therefore essential to providing excellent service.

There is a constant challenge to innovate and optimise. We work with a DevOps mindset and aim to make our services as efficient and reliable as possible. You’ll have plenty of room to contribute your own ideas and experiment with new technologies.

• You have a higher professional education level (Dutch HBO level) or equivalent level of working and thinking.
• You have experience developing serverless applications on AWS and deploying applications using CDK.
• You’re willing to learn other technology stacks and expand your knowledge.
• You’re enthusiastic, have a strong sense of responsibility and look beyond your own area of expertise.
• Team spirit. Your flexibility and ability to collaborate make the team stronger.
• You have experience writing automated tests, including unit, integration and end-to-end tests.
• You’re interested in the latest developments in backend technologies.

You are able to communicate effectively in Dutch or English.

At NS, diversity and inclusion matter to us. They make working together more enjoyable and help us achieve better results. Whatever your background or beliefs, we are above all interested in your perspective on this role.

• This role is not available on an interim or freelance basis.

Working at NS means having the opportunity to make a real impact on sustainable mobility. Together, we help keep the Netherlands accessible and connected for everyone.

At NS, you'll enjoy a high degree of freedom and responsibility, and we can promise you one thing: no two days are ever the same.

Our core values are openness and reliability. We are driven by results and continuously strive to move forward.
