Challenging work, good culture, difficult timelines
CFS as an abundance of difficult, interesting problems that they are working on diligently. On top of that, CFS is a very mission-driven company which leads to excellent, motivated coworkers who are most interested in how to succeed as a company and work together, as opposed to drama or politics. I genuinely love working here and can't imagine a more engaging place to work.
Like every startup, there are issues. CFS has not planned for enough space (desks and parking can be a pain) and schedules are often unrealistic. These concerns are acknowledged by management but ultimately the pain is felt by those engineers and technicians doing the work.
That said, if you have a good manager, they insulate you from a lot of that stuff.
