Downstream Process Development Engineer, Bioproduction

Job Description

Environmental Conditions

Some degree of PPE (Personal Protective Equipment) required (safety glasses, gowning, gloves, lab coat, ear plugs etc.)

 

Job Description

 

Thermo Fisher Scientific is seeking a Downstream Process Development Engineer to support development, scale-up, and customer enablement of downstream purification processes using our industry-leading single-use and hybrid purification platforms. This role is highly hands-on, customer-facing, and focused on large-scale chromatography execution, troubleshooting, and technology transfer.

 

Location:

This is an onsite position in Plainville, Massachusetts. Residency within commuting distance is required. No relocation assistance will be provided.

 

What You’ll Do

  • Develop and execute downstream purification processes across capture, intermediate, and polishing steps.
  • Perform hands-on large-scale protein purification, including operation of chromatography columns 30 cm to 60 cm ID.
  • Pack, qualify, and troubleshoot large-scale chromatography columns, ensuring consistent performance across cycles.
  • Diagnose and resolve pressure, flow distribution, and resin-related issues, including column fouling, pressure excursions, and yield losses.
  • Make real-time process adjustments during chromatography runs based on system trends and performance data.
  • Operate and optimize chromatography skids (single-use and/or stainless steel), including systems controlled via DeltaV.
  • Review process trends, alarms, and historian data to drive process understanding and improvement.
  • Generate high-quality technical data demonstrating robustness, scalability, and reproducibility.
  • Support PD → pilot → manufacturing scale transitions and participate in customer or internal tech transfer discussions.
  • Lead hands-on customer training, demonstrations, and technical workshops.
  • Collaborate cross-functionally with R&D, automation, manufacturing, and commercial teams.
 

Required Qualifications

  • B.S. in Chemical Engineering, Biochemistry, Biotechnology, or related field with 5+ years of relevant experience;
  • M.S. with 3+ years of relevant experience;
  • Ph.D. with relevant industry experience.
  • Hands-on experience with protein purification using chromatography, including capture, intermediate, and polishing steps.
  • Direct experience operating large-scale chromatography columns (≥30 cm ID).
  • Experience packing and qualifying chromatography columns in development or pilot-scale environments.
  • Strong ability to diagnose chromatography performance issues, including pressure, flow, and resin behavior.
  • Solid mechanical and fluid-flow intuition for packed-bed chromatography.
  • Experience operating downstream single-use purification systems.
  • Demonstrated end-to-end ownership of unit operations, with accountability for execution and outcomes.
  • Strong planning, execution, and technical documentation skills.
 

Preferred Qualifications

  • Experience operating chromatography columns 45–60 cm ID at pilot or manufacturing scale.
  • Hands-on experience with resin lifetime studies, reuse strategies, and column performance trending across multiple cycles.
  • Understanding of resin selection tradeoffs (binding capacity, pressure limitations, fouling risk).
  • Knowledge of cleaning, sanitization, and storage practices for chromatography resins and columns.
  • Experience operating chromatography skids using DeltaV, including navigation of batch phases and recipe logic.
  • Ability to collaborate with automation engineers on phase logic optimization and troubleshooting.
  • Familiarity with electronic batch records (EBR) or MES interfaces.
  • Understanding of scale-dependent risks, including flow distribution, pressure scaling, and residence time effects.
  • Experience translating small-scale learnings into robust operating ranges for pilot or manufacturing scale.
  • Experience supporting customer-facing troubleshooting, training, or technology transfer activities.
  • Demonstrated proactive identification of process risks and continuous improvement opportunities.

 

Physical Requirements

  • Ability to work in a laboratory environment and handle light to moderate lifting (up to ~50 lbs)
  • Standing and walking for extended periods during experimental execution
  • Manual dexterity to operate laboratory equipment and instrumentation
