Downstream Bioprocess Associate (Contract)

I'm looking for a hands-ondownstream bioprocess professional to join our Biologics Pilot Lab in Foster City. You'll help executepilot-scale purification runs, troubleshoot in real time, and support biologics programs from development through scale-up and technology transfer.

Why This Opportunity Stands Out

• Work directly with pilot-scale chromatography,TFF, viral filtration, depth filtration, centrifugation, and single-use equipment.
• Build practical skills in scale-up, end-to-end run execution, controlled documentation, troubleshooting, andtechnology transfer.
• Contribute to multiple early- and late-stage biologics programs in a collaborative, fast-moving environment.
• Gain meaningful continuity through a 12-month contract that runs from your start date.

What You'll Do

• Plan and execute downstream purificationruns, including clarification, chromatography,TFF, and viral filtration, in a schedule-driven pilot environment.
• Prepare buffers and reagents; set up, operate, clean, and tear down pilot-scale and single-use equipment.
• Pack and unpack chromatography columns, operateÄKTA systems, and useUNICORN methods for run execution.
• Document work in SOPs, batch records, run sheets, and summaries; capture observations and deviations clearly.
• Monitor process performance, interpret data, troubleshoot during runs, and communicate findings to cross-functional partners.
• Support process scale-up, comparability activities, technology transfer, lab readiness, and occasional weekend or extended-hour coverage.

What You'll Bring

• Required: Hands-on pilot-scale downstream bioprocess experience.
• Experience withdownstream purification operations such aschromatography, TFF, viral filtration, depth filtration, centrifugation, and buffer preparation.
• Experience operatingÄKTA systems and working with UNICORN; chromatography column operation experience is strongly relevant.
• Clear technical communication, documentation, organization, and collaborative problem-solving skills.

Your broader experience can come from bench, pilot, or manufacturing settings; hands-onpilot-scale work is the one must-have.

Nice to Have

• End-to-endpurification process execution rather than experience with only one unit operation.
• Biologicspilot plant,manufacturing support,technology transfer,or GMP-adjacent experience.
• Experience withsingle-use facilities, controlled documentation, process scale-up, or comparability activities.
• Flexibility to support occasional weekend or extended-hour run coverage.

Education

• AA/AS degree with more than 4 years of relevant industry experience indownstream purification or bioprocessing; or
• BS/BE in chemical or biochemical engineering, biochemistry, biology, or a related discipline with more than 2 years of relevant experience.
