Pros
Brilliant coworkers, great culture, cool office, flexible hours, & fun challenges. The Product, Design & Engineering teams are the best I've worked with in over 10 years of professional web/software development. Open access to cutting-edge industrial 3D printers in an amazing maker-space. Great opportunities for professional development in CAD, JS, TS, React, Node, Electron, three.js, GLSL, C#, .NET, Ruby, WiX . You can get close to the metal in your graphics-card... and then you get to hold the thing you imagined into existence.
Kontras
Some super talented people have left recently. GrabCAD still feels like a startup, but it's owned by Stratasys, so there is also a more corporate culture in evidence. The parking lot is kinda crowded (spaces are too narrow). I think the AWS IoT doorbell might be broken.
