Process Engineer

ABOUT US

Phase Biolabs converts waste CO₂ and renewable hydrogen into ethanol by gas fermentation, for use as an e-fuel in road fuel, as a low-carbon chemical feedstock and a sustainable aviation fuel precursor. We're a small team scaling a new biomanufacturing process.

As a process engineer working within a multidisciplinary team, you will contribute to the scaling and operation of our continuous gas fermentation process. This position is for someone who likes being a hands-on engineer, designing new systems, building and testing them and learning how they best operate.

If this role excites you but your experience doesn't tick every box below, apply anyway — we're looking for the right person, not a perfect CV.

• Help design, build and operate continuous fermentation systems
• Run continuous campaigns and turn the data into process improvements
• Design and operate auxiliary systems
• Integrate ethanol recovery by distillation with the fermentation
• Help refine the mass and energy balances that underpin our pilot plant design
• Work closely with our fermentation team on nutrient and gas delivery strategy
• Proactively troubleshoot, maintain, and get stuck into whatever else the process needs

• Likes being in the plant room as much as at the desk
• Is curious and data driven
• Takes ownership without waiting to be asked
• Isn't afraid to make mistakes
• Communicates clearly with people outside your discipline

• A degree in chemical or process engineering, or equivalent hands-on experience
• 3+ years working on real process equipment, at lab, pilot or plant scale
• Confident with P&IDs, mass and energy balances, and instrumentation
• Has commissioned or troubleshot something and seen it through

• Fermentation or gas-liquid mass transfer experience
• Distillation or separations
• PLCs, control systems or data acquisition
• Working with flammable gases (H₂)
