Pros
The owner is very enthusiastic about innovative science and is, at times, a blast to work for. He will keep you on your toes and keep you thinking outside the proverbial box. A major 'pro' for this company is that it's wide open, if you come up with a novel concept Enfold will give you the lab and resources to pursue it. I would give it four stars for the potential to make a big impact if your idea and personality are right.
Cons
Okay, now for the downside. Very very very little direction will be given - you are own your own. No timelines, no deadlines, and it often feels very unorganized. Unfortunately high employee turnover - for a small company this makes it difficult to complete projects in a timely manner. This job is best suited for PhD scientists with a few years industry experience who are comfortable working totally independently and managing multiple projects and employees. Be prepared to bounce from idea to idea, during my tenure management 'refocused' the company several times. I would not recommend this for BS or MS associates due to the lack of direction and oversight. Scientific equipment is old and breaks down weekly - this makes it difficult to do even basic analysis like 260/280 for DNA or even Bradfords.
