With strategic long-term investments into what we believe the future of travel can be, we are opening up new career opportunities that will have a strong impact on our mission.

At, historically, we’ve had some really mature tooling for rolling out changes and monitoring them. However as we work on migrating to Kubernetes on private and public cloud, and the company grows, the variety of ways we roll out changes and platforms we run on has grown. This growth has also been accelerated by a move to service-oriented architecture.

This means that there is a huge opportunity for working on exciting projects around what we call release orchestration and release verification. Release orchestration has historically been our primary focus, working on strengthening the tooling for deploying changes as fast and safely as possible, and easily being able to monitor who is rolling out which services and statistics around that. One of the areas we want to focus on going forward is around release verification, improving observability and confidence around rolling out changes. has a lot of mature observability tooling around monitoring services, but there is a huge opportunity to improve some of that when focusing on release verification and canary analysis, especially when adopting more modern developments around statistics and machine learning.
