People at InVision Say

This information was sourced from reviews originally posted on Glassdoor.

A great place to work, all around. Definitely some of the most consistently fun and interesting products I’ve worked on, with new challenges all the time. Good compensation. Work from anywhere (fully remote team). Many opportunities for growth and advancement. And, probably above all else, seriously fantastic coworkers.

The technology is interesting, consisting of lots of Dockerized micro services. I had a lot of latitude in design decisions in the services I implemented. Employees are encouraged to learn new things and share in group presentations.

100% remote, amazing team (everyone is super smart, humble and hard working), great company values and awesome product. If you love digital product design you will love it here!

Your colleagues will make this great. I can't describe the amount of great relationships I built at this company, and the tech stack is fun -- albeit implemented poorly.
