Ventajas
The people are amazing, and the work is incredibly interesting and rewarding. You learn A LOT and get to use what you learn in school. You can be working on cutting edge stuff.
Desventajas
Pay is below market for my current qualifications and experience. Benefits are quite decent. Plenty of bureaucracy makes prototyping (manufacturing and procurement) activities a nightmare. Management is switching gears to defence which I have serious ethical concerns about, because the CEO is from a defence background, that's all he knows. The technology the company works on can easily be ported to civilian applications that have more stable long term prospects, but because the CEO knows defence, MDA does defence. Management claims to listen (Just Ask) but doesn't actually listen and take employees requests seriously, even about important matters. As a result, there aren't enough parking spots in the new building, even though the company had been warned for months leading up to the move that this was a concern. Depending on how hard you push, the advancement opportunities for younger employees are mixed. Some get trainings and put on projects they want, others eventually leave for this reason. Recently the company is pushing for 4-day RTO, which has angered quite a few employees. Lots of us can do work from home with no trouble. If they have to work on hardware, they accommodate accordingly. Mandating this is a bad decision.
