Job description

Job Description & Requirements

BNL is looking for a versatile and hands‑on Biotechnology Engineer to join our team and focus on developing and scaling up fermentation technologies. This role is ideal for someone who enjoys problem‑solving across disciplines and is excited to work at the interface of lab‑scale R&D and real‑world deployment.

You’ll run fermentation experiments, operate pilot systems, and support the scale‑up of bioprocesses, while also contributing to adjacent R&D and process innovation projects as the company evolves.

Key Responsibilities

Fermentation & Process Development

• Design, set up, and run bench‑ and pilot‑scale fermentation systems under both aerobic and anaerobic conditions
• Optimise microbial growth and conversion parameters (e.g., pH, temperature, retention time, gas flow, agitation)
• Record, analyse, and present experimental data to guide system improvements and scaling strategies

Scale‑Up & Prototyping

• Translate lab findings into scalable process concepts, equipment sizing, and process flow diagrams (PFDs)
• Support design, fabrication, and testing of pilot and pre‑commercial systems, working closely with external partners and vendors
• Troubleshoot and iterate prototypes based on performance data, integrating both engineering and biological insights

Cross‑Functional R&D

• Collaborate with operations teams on multi‑disciplinary projects
• Assist with adjacent R&D efforts (e.g., pre‑treatment, recovery processes, digital monitoring systems) as needed
• Contribute to rapid prototyping, new concept evaluation, and internal process improvement initiatives
• Support other R&D initiatives as required

Field Testing & Deployment

• Support commissioning, monitoring, and optimisation of deployed systems in pilot or customer environments
• Participate in field trials, technology demonstrations, and documentation for knowledge transfer

What We’re Looking For:

• Bachelor’s or Master’s degree in Chemistry, Biochemistry, Food Science, Chemical Engineering, Bioprocess Engineering, Environmental Engineering, or a related field
• 2–6 years of experience in fermentation process development, pilot systems, or engineering R&D (startup or tech development experience a plus)
• Familiarity with fermentation principles, bioreactor operation, and biological process troubleshooting
• Comfort working on evolving systems, rapidly adapting to changes, and iterating based on real‑world results
• Experience building, operating, or scaling pilot setups or experimental rigs
• Solid documentation habits, strong communication skills, and a collaborative mindset

Bonus Points (Nice to Have):

• Experience with downstream processing (filtration, separation, etc.)
• CAD or process design tools (e.g., AutoCAD, SolidWorks, P&ID software)
• Exposure to hardware prototyping, control systems, or process automation
• Interest in sustainability, circular economy, or bio‑based innovation
