Engineering culture has been destroyed. This has been going on for quite a few years, but in the last 1.5 years, it rapidly increased. Most of the engineers with a deep understanding of the domain/product have left the company. Many of the engineers that are still with the company stopped caring, are worried about their future, and will jump ship when they get a chance.
Engineering managers have little or no experience with distributed systems and are primarily busy with writing reports and updating JIRA. Engineers are replaceable units and their opinions or understanding are ignored. It is a 100% top-down company.
All new hires are from the UK. Offices outside of the UK are closed. There is no career opportunity for engineers outside of the UK and it is likely that you will be replaced at some point.
If you are in the UK and consider joining, be warned. At first glance, it will look fine and it will look like 'leaders' know what they are talking about, but if you dig a bit deeper you will see the sinking ship. Please check the Glassdoor review history of other engineers.
