What is biotech process development?

Biotech process development refers to the design, optimization, and scale-up of manufacturing processes used to produce biological products, such as pharmaceuticals, enzymes, or vaccines. Professionals in this field work to turn laboratory procedures into efficient, large-scale industrial processes that meet regulatory and quality standards. This often involves selecting suitable equipment, optimizing conditions, ensuring reproducibility, and troubleshooting production issues. The ultimate goal is to produce high-quality products safely, consistently, and cost-effectively.

What are the key skills and qualifications needed to thrive in biotech process development, and why are they important?

To excel in Biotech Process Development, you need a strong background in bioprocess engineering, molecular biology, and chemistry, typically supported by a degree in biotechnology or related fields. Familiarity with tools such as bioreactors, chromatography systems, and data analysis software, along with certifications in Good Manufacturing Practice (GMP), is highly valuable. Strong problem-solving skills, attention to detail, and effective teamwork distinguish top performers in this role. These competencies are crucial for optimizing processes, ensuring product quality, and driving innovation in the biotech industry.

What are some common challenges faced by professionals in biotech process development, and how are they typically addressed?

Professionals in Biotech Process Development often encounter challenges related to scaling up processes from the laboratory to commercial production, ensuring product consistency, and meeting strict regulatory standards. Addressing these challenges typically involves close collaboration with cross-functional teams such as quality assurance, regulatory affairs, and manufacturing. Continuous process optimization, thorough documentation, and robust validation protocols are essential strategies to overcome these hurdles and ensure successful product development and commercialization.

What is the difference between Biotech Process Development vs Biotech Manufacturing Associate?

AspectBiotech Process DevelopmentBiotech Manufacturing Associate
Primary FocusDesigning, optimizing, and scaling up bioprocesses for product developmentExecuting manufacturing processes to produce biopharmaceuticals at scale
Work EnvironmentLaboratories and pilot plant facilitiesProduction floors and manufacturing plants
Required SkillsProcess design, lab techniques, troubleshootingEquipment operation, quality control, adherence to SOPs
Typical CredentialsBSc/MSc in Biotechnology, Chemical Engineering, or related fieldsBSc in Biotechnology, Biology, or related fields

While both roles are essential in biotech, Biotech Process Development focuses on creating and optimizing processes during product development, whereas Biotech Manufacturing Associates handle the day-to-day production to ensure consistent product quality at scale.

Job description

Downstream Process Development Scientist / Tech Transfer Consultant 

  • Employment Type: Contract
  • Compensation: $75–$90/hour, depending on experience and technical background.
  • Function: Process Development / Manufacturing Sciences / Technology Transfer
  • Reporting To: Associate Director
  • Industry: Biotechnology / Biopharmaceutical Manufacturing

Viltis is seeking an experienced Downstream Process Development / Tech Transfer Consultant to support a biotechnology client with downstream process development, pilot plant execution, scale-up, and technology transfer activities.

This contract position will work as part of an established process development team and report to an Associate Director. The consultant will take ownership of key downstream technical workstreams while partnering closely with internal cross-functional teams and external CMO/CDMO manufacturing partners.


Key Responsibilities

  • Support downstream process development, optimization, scale-up, and technology transfer activities.
  • Lead significant portions of downstream technical execution with external CMO/CDMO partners.
  • Support pilot plant and on-site scale-up activities, including execution, troubleshooting, and process evaluation.
  • Provide technical leadership for downstream unit operations, including membrane filtration and tangential flow filtration (TFF).
  • Develop, review, and support technical documentation associated with process development and technology transfer.
  • Evaluate process performance, identify technical risks, and recommend appropriate solutions during scale-up and manufacturing transfer.
  • Partner with Process Development, Manufacturing, Quality, Regulatory, and other cross-functional groups to ensure successful execution of program objectives.
  • Support activities associated with Process Performance Qualification (PPQ) campaigns.
  • Contribute to commercial manufacturing readiness and product launch activities.
  • Participate in technical discussions, investigations, troubleshooting, and decision-making with internal teams and external manufacturing partners.
  • Ensure downstream processes are appropriately transferred, understood, and executable at the receiving manufacturing site.
  • Operate effectively within a broader technical team while independently owning assigned downstream workstreams.

Required Qualifications

  • 10+ years of experience in biopharmaceutical process development, with substantial experience focused on downstream processing.
  • Strong technical expertise in downstream process development and scale-up.
  • Demonstrated experience with technology transfer to manufacturing facilities and/or CMO/CDMO partners.
  • Hands-on experience with membrane filtration and tangential flow filtration (TFF).
  • Experience supporting pilot-scale or manufacturing-scale downstream operations.
  • Strong understanding of downstream process parameters, process characterization, troubleshooting, and scale-up considerations.
  • Ability to independently lead technical workstreams while collaborating effectively within a multidisciplinary team.
  • Strong technical communication, documentation, problem-solving, and stakeholder-management skills.


Preferred Qualifications

  • Experience supporting PPQ campaigns.
  • Experience supporting commercial product launches or commercial manufacturing readiness.
  • Previous experience working directly with CMOs/CDMOs on process transfer and manufacturing execution.
  • Experience supporting biologics manufacturing in a regulated GMP environment.
  • Experience transitioning processes from development through clinical and commercial manufacturing.
