Site Reliability Engineer

TUI Travel’s vision is to make travel experiences special. To fulfil this vision, we never stop looking ahead, seeking new ways to delight our customers and grow our business. We recognise the power of digital and the massive contribution this brings to creating a truly unique and differentiated customer experience.

The Mobility Hub has a commitment to deliver the TUI Mobile App (TDA) for multiple countries across Europe and to all markets at a high level of quality and stability on a reliable and frequent basis. The scope and growth of the TDA is ever increasing and the ability to implement a continuous delivery pipeline that provides a stable delivery process is essential.

Site Reliability Engineers (SREs) are responsible for keeping all production systems running smoothly. SREs are a blend of pragmatic operators and software engineers that apply sound engineering principles, operational discipline, and mature automation to our environments and code base.

Joining the Mobility Hub team as Site Reliability Engineer, you will be key in maturing our organisation in continuous delivery and help with implementing the processes to ensure high availability and quality. I build it, I run it.

You may be a fit to this role if you:

  • Think about systems - edge cases, failure modes, behaviours, specific implementations.
  • Have an urge to collaborate and communicate asynchronously.
  • Have an urge to document all the things you do so you don't need to learn the same thing twice.
  • Have an enthusiastic, go-for-it attitude.
  • Have an urge for delivering quickly and iterating fast.
  • Share our values, and work in accordance with those values.

  • Run our infrastructure with CloudFormation and Terraform (all environments).

  • Debug production issues across services and levels of the stack.
  • Plan the growth of infrastructure.
