Core Responsibilities

Primary Functions

Lead development and optimization of microbial fermentation processes (yeast, bacteria and mixed cultures) from lab bench to pilot and commercial scale, implementing robust scale-up strategies, risk assessments and process controls to ensure consistent yields, product quality and cost targets.
Design, execute and interpret fermentation experiments, including media formulation, inoculum preparation, fermentation parameter screening (pH, temperature, DO, agitation, feed profiles) and statistical experimental design (DoE) to accelerate development timelines.
Manage yeast and microbial strain programs: strain selection, propagation, cryopreservation, genetic stability monitoring, phenotype characterization and documentation of lineage and performance metrics in strain libraries and LIMS.
Establish, document and maintain SOPs, batch records and work instructions for fermentation, downstream processing and aseptic handling that comply with GMP, HACCP and internal quality systems.
Own bioreactor operations including setup, sterilization (CIP/SIP), inoculation, on-line control systems, sensors calibration, troubleshooting of aeration/mixing issues, and coordination with utilities for reliable scale-up.
Implement and monitor process analytical technology (PAT) and in-line/at-line sensors (pH, DO, turbidity, Raman/near-IR probes) to enable real-time process control and reduce variability across production runs.
Drive analytical capability for fermentation: develop and validate methods for HPLC, GC, mass spectrometry, qPCR/RT-qPCR, spectrophotometry and plate counts to quantify substrates, products, metabolites, and contaminant profiles.
Conduct root cause analysis and corrective/preventive actions (CAPA) for fermentation deviations, contamination events or quality non-conformances using formal problem-solving frameworks (5 Whys, Ishikawa, FMEA).
Collaborate cross-functionally with R&D, QA/QC, engineering, supply chain and operations to translate research outputs into manufacturable processes and to ensure smooth handover to production teams.
Lead scale-up campaigns and pilot trials, including developing scale-up criteria, tech transfer packages, capacity planning, risk mitigation plans and acceptance criteria for commercial release.
Manage sample control, chain of custody and stability testing for fermentation intermediates and finished products, ensuring traceability and compliance with regulatory and customer specifications.
Optimize fermentation economics by analyzing raw material inputs, yield improvements, cycle time reduction, and utility consumption; propose process changes to improve margin and sustainability metrics.
Supervise and mentor junior scientists and technicians in aseptic technique, sterile media preparation, bioreactor operation and data analysis, fostering a safety-first and continuous improvement culture.
Plan and execute contamination monitoring programs, environmental monitoring and sanitation validation with corrective strategy development to minimize batch losses and maintain food safety compliance.
Develop sensory evaluation protocols and work closely with sensory panels to correlate process parameters with organoleptic outcomes, ensuring end-product consistency (flavor, aroma, mouthfeel) for beverage or ingredient applications.
Prepare technical reports, regulatory dossiers and internal presentations summarizing fermentation data, risk assessments, change controls and commercial readiness to stakeholders and external partners.
Maintain up-to-date documentation for equipment qualification (IQ/OQ/PQ), calibration records, and equipment preventive maintenance schedules to support process reliability and audit readiness.
Lead continuous improvement projects using Lean, Six Sigma or Kaizen methodologies to reduce variability, improve throughput, and increase first-pass yield in fermentation operations.
Evaluate, select and manage relationships with external vendors and contract manufacturing organizations (CMOs) for media, strains, sensors and pilot manufacturing services; negotiate scope, specs and timelines.
Apply molecular biology techniques (PCR, plasmid maintenance, basic cloning or transformation workflows where applicable) to support strain characterization and troubleshooting of unknown phenotypes.
Ensure compliance with local and international regulatory requirements (FDA, EFSA, USDA, other applicable food and beverage or biotech regulations) as they relate to fermentation products, labeling and safety.

Secondary Functions

Support cross-functional data requests and exploratory analysis to correlate fermentation process data with quality, yield and sensory outcomes; maintain a clean, annotated dataset for model building and AI/ML use cases.
Contribute to the organization's fermentation and microbiology strategy, helping define priorities for strain development, process automation and digital transformation of lab-to-facilities data flows.
Work with manufacturing and automation teams to translate process needs into control system requirements, SCADA recipes and batch control logic for repeatable commercial production.
Participate in project planning, resource allocation and agile-style rituals for R&D and process development projects; provide technical input on timelines and risk.
Provide training and guidance on biosafety, laboratory safety, GMP and sanitation best practices across departments interacting with fermentation zones.
Assist procurement and supply chain with technical specifications for raw materials (media components, nutrients, yeast banks) to ensure consistent quality and cost-efficiency.
Represent the organization in technical meetings with customers, regulatory bodies and industry partners to communicate fermentation capabilities and technical constraints.
Support pilot plant commissioning, validation runs and handover activities during new process or facility start-ups.
Keep technical skills current by attending conferences, reading literature, and integrating relevant advances (synthetic biology, sensor tech, bioprocess intensification) into actionable project proposals.
Aid commercialization teams by providing technical dossiers and scale-up insights required for product launches, customer audits and contract negotiations.
