Pros

Working at Tetra Tech has been such a rewarding experience, and what truly sets it apart is the people. From day one, I’ve been surrounded by colleagues who are not only incredibly knowledgeable and talented, but also genuinely supportive and collaborative. There’s a strong sense of teamwork here—people are always willing to share ideas, lend a hand, and celebrate each other’s successes. The culture encourages growth, open communication, and respect across all levels, which makes a huge difference in day-to-day work. Leadership is approachable and invested in both project success and employee development, and that creates an environment where you feel valued and motivated. It’s rare to find a workplace where you enjoy both the work and the people you work with, but Tetra Tech really delivers on that. The team makes even challenging projects feel manageable—and often even fun.

Cons

benefits-paid time off is not the best (but they offer flexibility) and the insurance is mid.

Pros

Not alone going for it right now. Every midwest office is struggling with work

Cons

Forced to use PTO when no billable work is available. PMs guard work and play favorites to who they distribute to. Raises are abysmal. No employee gets higher than 2% due to how profits are split company wide between operating units. Medical benifits were diluted to just Aetna and has higher premiums after having several options the previous years. DEI language was stripped from the company to satisfy the current administration.

Pros

The whole company went remote during the pandemic, and there hasn’t been a push to return to office. Vast company that seems well run. Job stability is good.

Cons

In my experience, pay is not competitive and raises are not given, even when requested and when an employee’s quals and experience merit it.
