Biolayer Interferometry and Antibody Testing

• Perform BLI assays using approved methods to support antibody verification, characterization, and conformance testing.
• Prepare assay plates, biosensors, controls, standards, samples, and reagents required for BLI testing.
• Generate and review BLI data, including assay controls, binding-response data, and defined reportable results.
• Perform antibody verification and conformance testing using approved test methods, reference materials, and acceptance criteria.
• Evaluate antibody identity, binding performance, specificity, concentration, activity, or other defined quality attributes, as applicable to approved laboratory methods.
• Document test conditions, calculations, results, observations, and conclusions in controlled laboratory records.
• Assist with troubleshooting assay failures, atypical results, invalid runs, out-of-specification results, and out-of-trend results under supervisory direction.
• Maintain appropriate handling, storage, lot traceability, and expiration control for antibodies, standards, controls, biosensors, and related test materials.

QA/QC and Quality-System Support

• Perform work in accordance with the laboratory’s ISO-accredited QA/QC program, approved standard operating procedures, test methods, safety requirements, and records-control practices.
• Maintain complete, contemporaneous, accurate, and traceable laboratory documentation in approved paper or electronic systems.
• Follow established procedures for sample receipt, testing, data review, deviation reporting, equipment use, reagent control, and records retention.
• Support test-method verification, equipment qualification, calibration checks, preventive maintenance, and performance verification activities.
• Assist with preparation and revision of standard operating procedures, worksheets, test records, protocols, and technical reports.
• Participate in quality reviews, internal audits, corrective-action activities, root-cause investigations, and continuous-improvement efforts, as assigned.
• Maintain laboratory inventory and verify appropriate storage, labeling, expiration dating, and availability of laboratory supplies and controlled materials.

Minimum Qualifications

• Bachelor’s degree in microbiology, biology, biotechnology, biochemistry, immunology, molecular biology, or a closely related scientific discipline.
• At least 3 years' experience performing the duties above
• Laboratory experience gained through employment, internships, research, coursework, or equivalent practical training.
• Knowledge of aseptic technique, bacterial culture, culture-media preparation, and basic microbiological testing methods.
• Familiarity with laboratory documentation, data recording, and use of controlled procedures.
• Ability to perform detailed laboratory work accurately and consistently.
• Ability to organize technical data, perform routine calculations, and communicate results clearly.
• Ability to work effectively as part of a laboratory and QA/QC team.
• Ability to complete and maintain required biological-material shipping training.

Preferred Qualifications

• Experience performing BLI assays or other antibody-binding, affinity, or immunoassay methods.
• Experience with antibody verification, antibody characterization, protein testing, or conformance testing.
• Experience in a regulated, accredited, or quality-managed laboratory environment.
• Familiarity with ISO quality-system principles, controlled documents, data integrity, traceability, deviations, corrective actions, or audit support.
• Experience with bacterial fermentation, bench-scale bioreactors, recombinant protein expression, or microbial production systems.
• Experience with laboratory information-management systems, electronic laboratory notebooks, or spreadsheet-based technical analysis.
