Pros

Smart and fun people. Transparent culture and management. Lots of genuine passion for the company's clean energy mission. Exciting and challenging work. Great career opportunities. Safety and employee well-being is taken seriously, and I've been impressed with how the company has handled operations during the pandemic. Growing fast and has great vision.

Cons

Hoping to see more women and minorities in senior roles soon. It's a start-up so of course there is lots of work to do - That being said I think that we could be even more proactive about hiring.

Pros

Lots of overtime Free snacks

Cons

Technicians are rewarded for working efficiently with additional work assignments. "Senior" technicians do the same work as entry level techs, while getting paid twice as much. Last minute travel with many adhoc extensions, sometimes keeping you away from home for multiple weeks Unfair and dishonest supervisors who will quickly throw you under the bus for a pat on the back Unsafe practices in the field Inflexible work hours and schedule This is the type of job where you are expected to be working 100% of the time, even if you complete your assigned job duties. You will be pawned off to another department for the day to ensure you don't get a break. Last time I checked, running a computer at full capacity will cause components to heat up and burn out, resulting in an unsustainable system. The same goes for humans working in a business.
