Pros

At one point, this was a good company to work for and had the chance to work with some genuinely great colleagues.

Cons

The company has gone downhill fast after changes in tech leadership. The Belfast office has basically been gutted, with a lot of roles offshored to India without any proper handover or knowledge transfer. This was justified by saying the skillset didn’t exist locally, which just wasn’t true. There have been at least three rounds of layoffs in Belfast (and more globally), and they couldn’t really have been handled much worse. These came after asking people to move to reduced working weeks, which didn’t sit right. Headcount in Belfast has gone from around 180 to, I’d say, under 50 in less than a year, and plenty of the ones left are already looking out. Some redundancies even had to be delayed because there were no engineers left to support certain products. Communication from leadership has been poor. Town halls felt completely disconnected from what people were actually dealing with, with no real acknowledgement of the layoffs. Local leadership in Belfast is basically gone. I get that restructuring happens, but this has felt like a mess from start to finish.
