If you work for ZCS itself remotely you will have it really nice. If you work on site at the CO facility then prepare for being treated as a second class citizen. After the Global Thermostat merger, many enticing benefits were offered to keep talent but then proceeded to slowly let people go. It’s a fundamental difference between remote workers who are competent at design but have not built a full scale system before not listening to employees who have and failing to address design flaws that have already been tested and failing to commit to a design to build to actually see if the design will work relying too heavily on simulations. Severe mistrust of the CO locations people/data with a head CTO that wants hands on micromanagement in every decision. Pay difference between remote workers and CO location is pretty dramatic from the people I’ve talked with. Take what I say with a grain of salt as a former employee, but understand that whatever ZCS says from a management pov is likely bat guano. If you get an interview and at the CO location, ask about the merger and ask where the employees are now after 6 months of that happening.
