  • Work hard, play hard. Competitive salary, wellness program, insurances, yearly company bootcamps, but also a lot of heavy lifting and crunching. We want to go above and beyond.

  • Anything but ordinary. We’re a fun and international crew with offices in Brooklyn and Södermalm, and an office atmosphere that’s often described as “too much”.
