Pros
Stable revenue stream, no threat of layoffs, decent campus in Natick with some creature comforts (gym, for-pay cafeteria, pastry counter, etc.).Benefits are okay. This company has been around for three decades, and will likely persist for many years to come.
Kontras
Sub-par salaries (by a wide margin). BIZARRE corporate culture of micromanagement and fear. Don't say the phrase "Open Source" anywhere. It's taboo. Don't suggest changing systems or procedures that are already in place. That's taboo. Don't refuse to go to ANY company event. The Eye of Sauron will quickly swivel your way. You WILL feel its baleful, needy glare. The CEO is excessively invested in minutiae to a pathological degree. Whether it's the widgets on your desktop system and its power management settings, or the color of the walls in the hallway, he has a strong opinion about it. I didn't believe the story about him setting guidelines for mounting clocks in conference rooms based on the position of screws in the whiteboards... until I heard about it from multiple coworkers. This place will stress you out while paying less than any other company would consider reasonable. Avoid, avoid, avoid!
