As Verley scales up its proprietary processes from laboratory to full-scale commercial production, we are reinforcing our downstream processing (DSP) expertise. The Senior Process Engineer DSP will act as a subject matter expert (SME) for protein purification and recovery, ensuring the robustness and scalability of our DSP operations. Reporting to the Lead Process Engineer, this role bridges R&D and industrialization, supporting the development, optimization, and transfer of purification processes to our external manufacturing partners.

This position requires strong technical expertise in DSP, hands-on involvement in process development and troubleshooting, and the ability to collaborate closely with internal R&D teams as well as external CMOs.

Key Responsibilities

Process Development & Scale-Up

• Lead DSP development activities from laboratory scale through to commercial manufacturing (filtration, chromatography, polishing steps, formulation).

• Optimize recovery yields, purity, and process robustness in coordination with R&D teams.

• Define critical process parameters and contribute to process characterization and validation studies.

• Support data analysis, process modeling, and implementation of technical improvements across scales.

Tech Transfer & CMO Support

• Prepare detailed DSP documentation (process descriptions, protocols, batch records).

• Provide technical input during tech transfer to CMOs, ensuring smooth scale-up to commercial production.

• Participate in on-site troubleshooting and support manufacturing campaigns as needed.

• Review and validate CMO process data and documentation.

Cross-functional Collaboration

• Work closely with upstream, analytical, and quality teams to ensure full process integration.

• Support regulatory and quality documentation related to DSP processes.

• Contribute to risk assessments and process control strategies.

Technical Leadership

• Act as the internal DSP subject matter expert, ensuring knowledge transfer within the team.

• Provide guidance to junior engineers and technicians in DSP operations.

• Promote best practices, technical rigor, and continuous improvement across DSP activities.

• 5–8 years of experience in DSP development and scale-up within the biotech, food, or biopharma industry.

• Proven expertise in protein purification techniques (filtration, chromatography, UF/DF, polishing).

• Demonstrated experience in scaling DSP processes from lab to commercial manufacturing scale.

• Familiarity with tech transfer and external manufacturing collaboration (CMOs/CDMOs).

• Strong analytical and problem-solving skills, hands-on mindset.

• Fluent in English; French is a plus.

• Willingness to travel occasionally to support industrial partners.
