About Us

At Teton, we are redefining the role of healthcare workers through cutting-edge AI technology. Facing a global nursing shortage, our solutions offer vital support to overburdened health systems. We are experiencing rapid growth, with patients and residents across 4 countries already benefiting from our technology. We distinguish ourselves by focusing relentlessly on product excellence and user experience, rapidly deploying solutions that make a real difference.

We require a physical presence in our office in Copenhagen, Denmark. We believe this enables the fastest and most efficient iteration cycles to build an impactful product that users love to use.

We want builders who move at extreme speed while maintaining quality. If you're not ready to work more than 9–17, this isn't for you. We are well funded and offer significant stock options. This job may require work trips abroad as most of our customers are in the US.
