What you can expect from us
There’s a few things about Lifesum that aren’t exactly the norm:

- Passion.Actions speak louder than words ever have. Every day, Lifesummers show the passion and dedication that has seen us climb to the very top. Our blame-free culture encourages experimentation, helping us all learn and grow.
- Trust.We’re not as formal as some, which means more freedom to suggest, champion and lead. This also means far greater personal responsibility - and we wouldn’t have it any other way. It works because we trust each other.
- Diversity.Including more than 20 nationalities, we enjoy a rich mix of cultures, worldviews and working styles - this is more than your average tech gig: these different perspectives make sure we’re solving the right problems.
- Balance.We want you to be happy - so go ahead! Talk food and health, exercise with others, live life and most of all, laugh! Learn what works for you and use that to help everyone.

If this sounds like your kinda gig, we'd love to hear from you. Send us your resume right away and tell us why you are interested in this position and why Lifesum and you are the perfect fit for each other.
