Employee Testimonials
Our Work is Impactful
We are performing important work that enhances our community and cleans up the environment. We offer competitive salaries and an excellent benefits package. Come join our team and help us make an impact.
“N3B has a unique mix of minds and talents who are enthusiastically dedicated to a single mission. I was new to the environmental industry and have learned so much in the past 19 months. Anytime I ask questions (I still have much to learn) they are answered with patience and passion – I can tell my co-workers take pride in their profession and enjoy teaching my curious mind. Additionally, I’ve had many opportunities for professional growth, a promotion and a salary increase to reward my hard work. I see no limit to continued growth here. The support and encouragement of my supervisors motivates and challenges me every day.”

The benefits are excellent and the corporation as a whole is a DOE contractor that is like no other. Corporate culture is very family oriented and encourages a good work/life balance. N3B has high expectations of its people and the team delivers accordingly.”
