Sr. Production Process Engineer

What you’ll do

We are looking for a Senior Process Engineer to (i) get our newly commissioned First-of-a-Kind (FOAK) TXS-1 gas fermentation plant in Houston, Texas, running smoothly at full nameplate capacity, (ii) assist with the design and construction of our next, much larger commercial plant, and (iii) own the commissioning and startup of this next commercial plant.

• Oversee production engineering for TXS-1, Again’s first commercial gas fermentation plant
• Manage engineers and technicians
• Optimize and debottleneck production processes, particularly gas fermentation and related upstream equipment including media preparation. Downstream processing steps will also require your attention
• Ensure safe and smooth operation of all plant equipment
• Oversee improvement projects and lead root cause analyses (RCAs)

• You have practical experience (>5 years) in production and process engineering in a plant setting
• Hands‑on experience with industrial reactors—operation, optimization, debottlenecking, troubleshooting
• BS in Chemical Engineering, Bioprocess Engineering, or similar
• You are collaborative, communicative and can work closely with our scientific and process engineering teams. You can also collaborate with and give clear direction to our Automation personnel
• You lead by example and can operate independently. Although you will be managing other engineers, this is not a desk job—significant presence in the field is required
• Willing to relocate to the Houston, TX area

• Strong competence within bioprocessing and a deep understanding of gas/liquid mass transfers, sanitary design, aseptic operations, and experience with gas fermentation is a plus
• Experience with unit operations like media prep, tangential flow/cross flow filtration, ion exchange, centrifugation, liquid-liquid extraction, and distillation is a plus
• Experience in plant commissioning, startups, and turn-arounds
• Project management and people management experience are plusses
• Mechanically‑minded ("handy") process engineers will be favored. Maybe you know how to take apart a pump, maybe you can help troubleshoot a compressor, etc.

• You get to work with a group of passionate scientists and engineers, working on challenging and meaningful projects
• This will be the journey of a lifetime – we are pioneering a new era of industrial manufacturing using biotech to make clean and resilient supply chains, and you can play a pivotal role in making that happen
• An ambitious, empowering and engaging work environment
• We understand that relocating can be a hassle, so if you don't live in Houston, Texas we will help out to give you a smooth transition. Note the exact location of the FOAK production site is Texas City. US citizen or work permit is required
• We live by our company values:
  Relentless Grit, Unreasonably Ambitious, Unconventional Thinking, Critical Urgency
• Health, dental, and vision insurance; 401k match; company equity; performance bonus; PTO and sick leave; parental leave; and a stocked kitchen
