A great place to work
A great place to work
Intelligent, motivated, passionate team of coworkers who are working towards a singular goal. With many people working on getting SPARC designed and built, there are not major conflicting priorities or teams under cutting each other to look good at another's expense.
The company is transparent for how things are going across the board- progress towards goals, financial performance, hiring, discussing key issues, etc. They treat us like adults and communicate the good and the bad regularly via monthly team meetings, quarterly all hands meetings with open questions requested and honest answers given. It is refreshing.
Employees have a lot of latitude to explore and think outside the box and also have access to a vast array of in-house expertise to solve problems.
There is a new, objective, merit based performance review and stock/salary award program in place to reward performance.
Lots of opportunities to learn and grow through your daily work and interactions. It does help to be on site regularly, but hybrid and remote employees are still in the loop and as accessible and involved as anyone on site, for the most part.
The on-campus cafeteria is excellent- great variety, inexpensive, and healthy.
Shuttle from the Red line to Devens makes it possible to commute without having a car.
Onboarding is straight forward and well set up- this is the first job they were actually ready for me to start with a computer, badge, work space, swag, etc on day 1.
At over 1000 people spread across the US (and beyond), it's a big organization with a lot of layers, nuance, and tribal knowledge. It can be difficult at times to get to the right person for help, but this problem is solved by being on site frequently and being engaged with coworkers to develop the internal network.
We still have good startup vibes but are also experiencing inevitable growing pains with processes and systems so you have to rely on your immediate team and adjacent systems to keep you in the loop sometimes for things that may impact your work.
Parking is tight with shuttles to remote lots needed on the busiest days if you're not in early. It's not so convenient but it does work.
