<h1>Fermentation Engineer</h1>The roleWe’re looking for a highly ambitious Fermentation Engineer to push every part of our fermentation process forward.We’re a small, high-talent-density team operating at the frontier of protein fermentation. Every hire changes the trajectory of the company. We look for people who take ownership, move fast, think unconventional and materially improve performance.We’re preparing to build our first commercial demo. The system you shape at our pilot today will define how we perform at commercial scale tomorrow.We work full-time on site because complex systems are built best together. Ideas move faster when you can walk to the fermentor, sketch on a whiteboard, and challenge each other in real time. This is a team sport, built shoulder to shoulder.Your work lives mainly at pilot scale and beyond. This is not theoretical optimisation. You will run high-performance continuous fermentations, analyse real-time data, identify constraints, challenge assumptions, and redesign what doesn’t make sense. We build from first principles. If “industry standard” slows us down, we rewrite it.There is real autonomy, and you’re expected to use it. The person closest to the problem decides. If something is broken, you fix it.Speed matters. We run experiments, learn, and iterate fast. Mistakes are fine. Repeating or hiding them is not.You will get your hands dirty: reactor modifications, control redesign, sensor integration, or software hacks. You’re comfortable in noisy, hot, and operationally messy environments.Freedom comes with responsibility. You own your decisions, technically, ethically, and financially. You treat company resources like your own and only buy for speed or real quality.We operate on trust and intellectual honesty. You challenge ideas directly and accept being challenged. You care more about outcomes than credit.You learn fast, adapt quickly, and stay humble… even when you’re very good. Your growth curve here is limited only by how much you can handle.This is not just a job. We’re building infrastructure that could fundamentally change how protein is produced. If that excites you, apply.We want the best people in the world.

This is a hardware and fermentation company so proximity matters. We believe people learn through osmosis and do their best work close to each other. We move fast because execution determines survival.

Agriculture has taken over almost half of all habitable land on earth, pushing nature over the brink, and the world needs an affordable protein source that can be produced without the need for agricultural land. Farmless has found a way to achieve this: by brewing carbon-negative, functional proteins with a complete amino acid profile.
The Farmless process combines the ancient craft of fermentation &ndash; which has been used for millennia to brew beer and bake bread &ndash; with a modern feedstock (the scientific term for a starter liquid). &nbsp;Whereas most fermentation companies rely on sugar, Farmless uses a feedstock made from CO2, water, nitrogen and renewable energy &ndash; bypassing the need for agricultural land. &nbsp;
