Roblox | San Mateo CA | Onsite, Full Time
We're building what I'd have loved at 12 when I wanted to automate my Legos and Construx. It's a scriptable, distributed physics engine with networking support and a social network overlaid on top. 
 Clients run on PC, mobile, and console. Devs publish their game and we spin up servers for them, make physics and networking work, support in-game currency, advertising, etc. Top games have 30k+ simul players, but the tail is very long.
We have over 40m monthly active users, and some devs on the platform are making 100k USD/month (and are still in high school, and have hired their friends to form studios).
We're hiring physics/rendering/networking C++ engineers, windows devops engineers (big scale), C# (or willing to learn) full stack engineers, and data scientists. Check it out at <a href=" - it's a downloadable client (to support native 60fps graphics). Make sure to try "Natural Disaster Survival".
