Vantaggi
They encourage cross-training, most shifts are M-F (8-5). They offer a decent benefit package BUT they tie 401k matching to unattainable company performance. They used to have a good atmosphere where the company held several events for employees but that's gone.
Svantaggi
The company is not stable. In the time I was there, it grew from 100 employees to almost 200, and then down to approximately 50 through 6 lay-offs, 4 within a year. Salary isn't merit based though they have reviews 2x per year, and reviews are used to determine the next round of lay-offs. Raises are very rare, and only certain people get bonuses. Some employees have unjustifiably high salaries (recent grads, close relations to upper-management). Heliae is too small to be stable or honest, and they don't adhere to their core values. Problematic employees are mostly ignored.
