Direct Hire



Imagine a meat company unlike anything that has come before! We are on a mission to impact climate change by revolutionizing how we make meat. Founded in 2019, we make protein from elements of the air.


We are a modern food company, crafting the world’s first air-based meats to feed us more sustainably, help renew the planet’s resources and eliminate compromise between nutrition, taste and climate impact. Using novel technology inspired by NASA, we convert elements found in the air around us into protein using probiotic cultures, then turn those proteins into any meat imaginable. It’s where cutting-edge science meets bold ambition to reinvent the way we eat.


Join our team of passionate scientists, engineers, and business leaders working to transform the future of food with solutions we never thought possible, creating meat that is nutritious, delicious and more sustainable. We use less land, less water and is significantly faster to make than any other meat available.


In addition to the chance to work with cutting edge technology to help combat climate change and working toward addressing the impending food crisis, employees also enjoy competitive benefits and total compensation plans and a collaborative company culture. If you join us on this relentless pursuit for more, changing the world will soon feel as natural as taking a breath.

We are funded by ADM, a world leader in fermentation technology, GV (formerly Google Ventures), and Barclays, one of the world’s leading financial institutions.
