HASH is a venture-backed startup building an open-source platform for simulation. We’re on a mission to reduce market failure by making powerful analytic and decision-making tools available to everybody.

About this role

  • Desire and ability to cope with the pace expected at a high-growth startup
  • Exceptionally self-motivated, "smart and gets things done", capable of end-to-end planning and problem-solving
  • Strong written and verbal communication skills (fluency in English required)
  • Unwavering attention to detail; incredibly organized


  • Prior experience in Operations is not required, but may be beneficial (in particular if at a high-growth startup)
  • Working knowledge of SQL or a desire to learn

Pay & Benefits

  • Competitive salary and generous equity
  • At least 30 days of global annual holiday
