      Really Positive Environment

      Senior design engineer
      Recommend
      CEO approval
      Business Outlook

      Pros

      The working culture is very relaxed. Management are mixed in with employees and are very approachable. There is a strong focus on you as an individual and putting yourself first. I have always found that I will be supported in anything new I wish to take on.

      Cons

      Salary could be higher. This is made up for by the wider package and work environment.
