Who we are

Employment Hero is on a mission to make employment easier and more valuable for everyone around the world. Our Employment Operating System brings hiring, HR, payroll and benefits into an all-in-one solution.

Since launching in 2014, we've grown from startup to global scale, reaching a valuation of over $2 billion and building a presence across six countries, with even more growth ahead. We now serve over 350,000 SMEs, pay more than 3 million employees, and support a growing pool of job seekers finding their next role through our platform.

The EH Way

At Employment Hero, we're proud of our unique DNA, which we call The EH Way.

  • We are Mission First – Our Mission determines what we work on, where we invest, and where we focus. Every decision runs through a single filter: does this accelerate our Mission?
  • We are Remote First – We champion a remote environment with a preference for asynchronous communication and a high degree of autonomy.
  • We are AI First – We are committed to using AI to accelerate our mission; AI is not just a tool, it's a fundamental part of how we operate, innovate, and scale.
  • We Live by Our Values – We role model our values 100% of the time.
  • We Expect High Performance – We set a high standard and we're not satisfied with being average.

  • Take initiative in recommending improvements to the development process
  • Proactively identify application pain points and suggest mitigation strategies
