Together with your team(s), you shape the digital experience of millions of passengers, from booking to boarding. As a Full Stack Developer in the Onboard Portal & Inflight Connectivity team, your work directly contributes to smooth, reliable and memorable journeys in the air.

At KLM, we believe great technology is built by diverse teams. Different perspectives make better products, and that’s exactly what we aim for.

What will you do?

As a Full Stack Developer, you play a key role in designing and evolving our inflight connectivity platform. This platform connects onboard systems, applications and devices with each other and with the internet, in a complex, safety-critical environment.

In addition, you will:

• Monitor and continuously improve product quality within a fast-evolving codebase and diverse infrastructure;
• Contribute to architecture and design decisions, aligned with modern industry best practices;
• Work across the full development lifecycle: specification, design, development, testing, delivery, maintenance and support;
• Collaborate closely with colleagues, product owners and external partners;
• Actively contribute to DevOps practices and a culture of shared ownership.

Where do you land?

You will join the Commercial Digital domain within KLM/Air France, organised according to SAFe principles. You’ll work in a small, committed team that values collaboration, quality and continuous improvement. Together with connectivity suppliers and internal stakeholders, you help build innovative solutions that enhance the passenger experience worldwide.
