      The most supportive place I've ever worked. From my coworkers to the management team, I am continously grateful for this positive, collaborative work environment.

      Cons

      I have nothing negative to say about working here. NSF is high on my list of blessings in my life.

      Interesting work and great colleagues, but poor leadership

      Technical reviewer

      CEO approval
      Business outlook

      Pros

      Work is interesting, people are great except for senior leadership. Work can be monotonous but there is opportunity for some cross training which helps; middle management is great for the most part

      Cons

      Pay is below average for industry and there is a huge range in pay for people doing the exact same work; promotions are difficult to receive - we shouldn't have to interview for promotions. Employees should have the opportunity to be promoted just based off merit and experience; "hybrid" work model forced upon employees when jobs can be done remotely; lack of care for employees from senior leadership
