Pros
Solar Ship has an ambitious mission: solar-powered electric flight to serve remote regions of the globe. Working for Solar Ship felt a bit like being a Wright Brother - every day was different, and there were equal parts office and hands-on labour. Never boring, and often extremely challenging, in a good way. A good place to work if you like to keep things interesting. Also great if you live in or around Brantford - not many other opportunities like this in southern Ontario!
Cons
While I was an employee, Solar Ship suffered from rapid employee turnover, probably because the work environment can be politically charged. If you don't believe in the vision, you'll probably feel unwelcome. Working hours can also be difficult (3am wake-ups for test flights, sometimes on weekends). Finally, perhaps this has changed since I left, but much energy always seemed to be devoted to finding new investors, sometimes at the detriment of employees' happiness.
