Great for your resume, below standard pay

Environmental scientist

Recommend

CEO approval

Business Outlook

Pros

Putting Tt on your resume is decent since they're well-known in the consulting industry.

Cons

Depending on your department and your supervisor, pay could be well below industry standards. Sometimes the projects are non-technical. This is a huge company though, and many offices often handle different aspects of engineering, so it's a toss-up what your group will be like.
