What you expect from us

There’s a few things about Lifesum that aren’t exactly the norm:

  • Passion. As obesity rates soar, people are left feeling more and more out of control of their bodies and their actions. Lifesummers bring their greatest skills to bear, knowing that we are tackling a serious global problem.
  • Trust. We work with little less formal structure than other companies, leading to more freedom and more responsibility for our staff. It works because we trust each other to work in the company’s best interest.
  • Diversity. Our team comes from over 20 countries, bringing with them a rich mix of backgrounds, world-views and working styles. We rely on these different perspectives to make sure we’re solving the right problems.
  • Balance. We’re normal people just like you. But working here you’ll find it easier to talk about food and health, to exercise with others if that’s your thing, and to share everyday problems. After all, these are the problems of our customers too.

If you think this sounds exciting, we'd love to hear from you. Send us your resume right away and please tell us why you are interested and why Lifesum is the place you want to be.

We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of sex, transgender identity or expression, ethnicity, religion or other belief, disability, sexual orientation, or age.
