Pros
I've worked for a couple of Fortune 500 tech companies and a medium size startup, and I enjoyed many aspects of those experiences. I worked with some very talented and accomplished people. They had great resources. Their products made a big impact in the world. At Lucid Software, the team is as talented and enjoyable to work with as any team I've had in my career. People are capable and work hard. The focus is on the work and people don't have big heads. The CEO works to develop all employees, both personally, and by assignment through the other managers. People throughout the organization are asked to participate in conferences, interact with customers, and contribute to company strategy and planning meetings. A lot is expected of me, but it is exhilarating as I'm provided latitude, trust, and support.
Cons
The work is demanding, but I would not have it any other way. I work hard, but my manager is aware of my efforts and sensitive to making sure the work is not too much. People who want a 9-5 job would feel uncomfortable here.
