Skyscanner operates in a Tribes and Squads model and we have built an engineering culture where there is a high level of trust, autonomy and transparency. Our engineers work in autonomous squads where they can create their own backlog, ship code whenever they want and don’t have dependencies in order to deliver to the traveller. Our engine uses global scale services, big data and machine learning to assemble, normalise and make sense of real time information from our thousands of partners. Skyscanner can offer you large scale, complex problems where you can reach over 90 million monthly active users whilst enjoying a high level of autonomy and influence and a flexible working environment where you can thrive.

Our engineering principles are:

  • We have a clear definition of success for every piece of work.
  • We ship multiple times a day and deliver customer value week in, week out.
  • We use design reviews to validate every significant change.
  • We deliver our products using our defined technology standards.
  • We peer review every change.
  • Our Definitions of Done include being live in production… responsibly.
  • You build it, you run it.

Most importantly, these are organic beliefs. We iterate. We learn. We grow. And our principles adapt with us.

Do you relish in technical leadership? Would you consider yourself an authority in your domain? Can you enable teams to move faster, smarter and more efficiently in a continuous delivery manner? If you enjoy collaboratively guiding company wide technology initiatives and principles, then this could be the role for you.
