By combining millennia-old bacteria with cutting edge technology, we turn CO2 into carbon negative chemicals.

Are you passionate about saving our climate? If you want to get your hands dirty to make our world cleaner, then get in touch! We welcome all applications. Just submit your CV alongside a cover letter to tell us why you would be a great addition to the team. We are based in Copenhagen, Denmark and are open to all types of applications: full-time, part-time, internships. Join us on our mission to remove 1 gigaton of CO₂ from the atmosphere Again uses biology to capture carbon dioxide from industrial emitters and transforms it into green petrochemicals. Our process is a win-win for industry who can reduce their emissions cost-effectively, whilst we produce green chemicals that lower emitters' carbon. With funding from top venture capital investors, as well as support from the European Union, we are looking to grow our team to save the world. Join an experienced team of biologists and entrepreneurs from the DTU, Stanford, MIT, TU Munich and University of Aalborg. If you are ready to fight climate change with science, Again is the place for you.
