Senior Full-stack Engineer

  • Anywhere

At Arkadium our purpose is to have fun while creating fun – and that’s exactly what we’ve been doing for 20 years. We’re the creators behind the world’s most-played games. From the Solitaire that came on your Windows machine, to hundreds of other games you’ve come to know and love – you can find our games on, iOS, Android, and lots of other big sites worldwide.

As a proud Evergreen business our values of Fierce Drive, Positive Energy and Living Full Lives are the driving force behind how we run and the choices we make.

We’re privately held (aka stable and reasonable about growth), founder-led (aka passionate about our craft) and we consistently rank as a “Best Place to Work” (aka not your typical games company).

We’ve been recognised by “Happiness Works 2023” in Portugal, “Crain’s Best Places to Work 2022” and “Great Place to Work 2022 and 2023” in New York!
