Pros

Great culture and prospects. Honest leadership with focus on good work/life balance and part of a larger organisation with plenty of resources. Roles ranging from data engineering to SRE to SWE.

Cons

Can't think of any. Maybe if aviation isn't your thing?

Pros

Brilliant place to work if you want something fast paced and challenging. Engaged cross-functional teams and brilliant top down strategy from senior leaders. The lack of red tape means ideas can be tested fast and decisions made in a timely manner. Pay is highly competitive and the recently updated benefit package is very welcome.

Cons

Sometimes the meeting rooms run a tad bit warm.
