Scale-Up Engineer / Manager (Solid state Fermenter)

Role Summary

We are looking for a talented bioprocess professional to lead solid-state

fermentation scale-up for microbial products and enzyme-based solutions. This role focuses on translating lab protocols to pilot and commercial scale, optimising yield, ensuring process consistency, and building scalable SSF systems.

Key Responsibilities

Process Development & Scale-Up

• Scale solid-state fermentation from lab to pilot to manufacturing scale
• Optimise substrate selection, pre-treatment, moisture & and aeration control
• Develop fermentation SOPs, batch protocols, and critical control parameters
• Monitor growth kinetics, sporulation efficiency, and metabolite production

Operational Execution

• Plan and run SSF batches
• Work closely with production teams for smooth tech transfer
• Troubleshoot contamination & variability issues
• Support capacity planning & cycle time optimisation

Quality & Documentation

• Implement QC standards: CFU/spore count, viability, contamination tests
• Maintain batch records, process sheets and validation reports
• Ensure compliance with biofertilizer/biopesticide regulations

Equipment & Infrastructure

• Work with engineering on SSF infrastructure
• Coordinate maintenance and improvement of SSF equipment
• Evaluate vendors for consumables, dryers, inoculation equipment, and automation.

Qualifications

• M.Tech / B.Tech / M.Sc in Biotechnology, Microbiology or Biochemical

Engineering

• 3 to 7 years of hands-on experience in SSF scale-up / production
• Experience with fungal fermentation preferred
• Strong knowledge of fermenter design, aeration, heat transfer, substrate handling, and microbial kinetics

Preferred Skills

• Practical knowledge of spore production & formulation
• Familiarity with downstream processes: drying, grinding, mixing, stabilisation
• Knowledge of QA/QC in microbial fermentation
• Understanding of industry standards (FCO/CIB norms preferred)
• Strong analytical ability & problem-solving skills
• Hands-on experience working in pilot or industrial fermentation units
