Working @ NS1

We’re a small, well funded startup with a casual work environment and strong work ethic. There’s a lot to do so we keep meetings and process to a minimum. We’re headquartered in NYC’s Financial District. We like to have fun, but skip most of the fancy startup gimmicks (fresh beer yes, gourmet chef and afternoon yoga no). We prefer candidates local to NYC or SFO, but will happily consider well qualified remote employees.

We offer:

  • competitive compensation (salary and stock options)
  • medical, dental, and vision
  • commuter benefits
  • 401k
  • flexible hours and time off
  • choice of workstation

NS1 is an equal opportunity employer.
