About the company 

Number 8 Bio is a venture-capital-backed start-up company with the potential to make a big climate impact. We work with farmers to provide solutions to agricultural sustainability while improving their productivity. Our first products are feed additives aimed at eliminating methane emissions from earth’s 2.6 billion cattle and sheep.

Methane is a greenhouse gas responsible for ~30% of climate change, and is both more potent and shorter lived than carbon dioxide. Eliminating man-made methane emissions is one of the fastest ways to combat climate change, while ensuring that we can sustainably support a population of 10 billion people by 2050 and beyond.

We’re a team of innovators based in Sydney with a passion for climate technology and synthetic biology. We offer a thriving intellectual environment, competitive remuneration, flexible work hours, and a chance to make a real difference.
