Core Responsibilities

Primary Functions

Lead development and optimization of fermentation processes for enzyme and microbial production, including design and execution of bench-scale and pilot-scale bioreactor campaigns to improve titer, yield, productivity, and product quality while reducing cost of goods.
Design, execute, and analyze Design of Experiments (DOE) to identify critical process parameters (CPPs) and critical quality attributes (CQAs) for upstream and integrated downstream workflows; translate DOE results into robust process control strategies.
Scale laboratory protocols to pilot and early commercial production; prepare scale-up rationale, heat/mass transfer assessments (kLa, mixing time), and risk assessments to support successful scale transitions.
Develop and refine fermentation media and feed strategies (batch, fed-batch, continuous/perfusion) tailored to strain physiology to maximize enzyme expression and stability across scales.
Work hands-on with lab and pilot fermenters (0.5 L to multi-thousand liter scale) performing bioreactor setup, sterilization (SIP/CIP), inoculation, process control, inline/outline sampling, and aseptic technique to ensure reproducible runs.
Implement and maintain process analytical technologies (PAT) and real-time monitoring (pH, DO, biomass, off-gas, spectroscopy) to enable closed-loop control and data-rich process characterization.
Lead integrated upstream-downstream process development projects, assessing how upstream changes (strain, feed, induction) impact downstream recovery, purification, and final product stability and purity.
Establish and optimize downstream unit operations relevant to enzyme production (cell harvest, lysis/clarification, filtration, chromatography, concentration, formulation), providing clear acceptance criteria for each step.
Collaborate with strain engineering and molecular biology teams to align strain attributes and expression systems with manufacturability goals; provide feedback on genetic construct performance under production conditions.
Create, review, and maintain detailed technical documentation including batch records, SOPs, process descriptions, risk assessments, and scale-up reports in compliance with GMP/GLP practices when applicable.
Drive process robustness and reproducibility through root cause investigation of process deviations and failed campaigns; lead corrective and preventive actions (CAPA) and implement process improvements.
Develop cost of goods (COGS) models and process economics analyses to prioritize development efforts and recommend strategies for yield improvement, raw material optimization, and downstream efficiency.
Perform analytical method development and validation for key in-process and release assays (protein titer, activity assays, HPLC/UPLC, SDS-PAGE, LC-MS, GC, spectrophotometry) in coordination with QC.
Coordinate cross-functional transfer of optimized processes to manufacturing, including preparation of tech transfer packages, process training for operations, and support during first manufacturing lots.
Manage and mentor junior scientists and technicians running day-to-day fermentation activities, ensuring training on aseptic technique, data capture, and lab safety.
Establish and enforce biosafety, aseptic, and contamination-control protocols in upstream labs and pilot facilities; participate in facility design reviews for fermentation suites and utilities.
Use statistical and computational tools (Python/R/MATLAB, JMP, Spotfire) to analyze process data, build predictive models, and generate actionable insights for continuous improvement.
Lead supplier/consumable assessments for media components, resins, and fermentation hardware; qualify vendors and ensure supply chain reliability for critical inputs.
Participate in regulatory and quality discussions to ensure processes meet applicable standards for enzyme or microbial products (food, feed, industrial enzymes; or biotech therapeutics if applicable).
Drive sustainability and green chemistry initiatives by evaluating media/supply alternatives, water and energy efficiency, and waste minimization across upstream and downstream processes.
Plan and execute pilot campaigns to generate manufacturing-ready process data, including reproducibility studies, hold/stability testing, and scale validation runs.
Prepare technical reports, presentations, and publications summarizing process development progress and recommending next steps for business stakeholders and investors.
Support commercialization activities such as process optimization for cost reduction, troubleshooting production bottlenecks, and participating in product launch readiness assessments.
Maintain up-to-date knowledge of zymology, fermentation engineering, enzyme assay techniques, and industry best practices through literature review and participation in technical conferences.
