Pros
Strong Mission: What Structural is trying to do is really powerful and can make a meaningful impact in the industry. If this speaks to you then you can find your fit within the team. Work atmosphere: You can work your own hours and deliver your best results. The team values results and passionate work more than it cares about hours and job titles. Growing team: You can maximize your impact and deliver great results since the team is relatively small in size. There is an opportunity to show your work off to the team and be proud of it. Everyone celebrates each others successes. Tools at your disposal: You have the opportunity to use the best tools, software and methods to get your best work done.
Cons
Career progression: "Climbing the ladder" may not be an option since its a startup and the hierarchy is pretty flat. Distributed team across a few cities and recommended work from home twice a week can make it harder to interface with colleagues and make friends.
