Key Specialists

KLM is a digital pioneer in aviation. At KLM Tech & Data, key specialists build e-commerce, APIs and apps that make travel easier for customers and colleagues.

At KLM Tech & Data, our key specialists are building the digital backbone of aviation. Developers, analysts and architects collaborate on platforms that support millions of customers and colleagues every day. Their work ranges from e-commerce to crew applications, and from APIs to complex backend systems.

A pivotal component is the Order API, the transactional core behind bookings, payments and upgrades. This story explains how this backbone keeps every flow secure and reliable, while preparing for the ONE Order standard so customers can travel with a single order reference.

This is what it looks like

Our engineering practices mirror that ambition. In API-first working at KLM, engineers describe how microservices and APIs accelerate releases and keep solutions scalable. That is the environment in which key specialists thrive—decoupling domains, securing data flows and automating tests to ship safely.

When KLM launched Premium Comfort, the team implemented the product logic that made it bookable across all channels, a concrete case also highlighted in the Order API story. These choices connect directly to the passenger experience and show how critical the role of our specialists is in shaping innovation.

Room to grow

Joining this team means immersing yourself in an environment where business and technology truly meet. You will work with microservices, cloud platforms and advanced testing frameworks, and you will have the opportunity to specialize in the latest technologies in API design and database architecture. There are also clear pathways to strategic or architectural roles. Training programs, international collaborations and knowledge-sharing networks ensure that you continue to develop.

Your role

As a key specialist, you translate customer and business needs into scalable software. You design and harden APIs, guard the integrity of critical chains and accelerate releases without compromising on security or quality. In doing so, you steer KLM’s digital future—visible in every channel where travelers book, pay and upgrade.
