- Maintain traceability of critical reagents, bead lots, conjugation materials, equipment, methods, and resulting data.
- Support customized conjugation of molecules to Luminex beads in a regulated environment, including testing to ensure bead quality and functionality per customer requirements.
- Develop and perform complex bead coupling protocols and conduct complex bead testing services in a regulated environment.
- Perform laboratory work in accordance with approved SOPs, protocols, Good Documentation Practices, data-integrity requirements, and applicable GLP quality-system procedures.
- Conduct critical reagent characterization and stability assessment using analytical techniques such as FPLC, capillary electrophoresis, and BLI.
- Support change-control, corrective-action, method-qualification, equipment-qualification, and audit-readiness activities relevant to bead-conjugation services.
- Support training programs for new and existing customers on xMAP instrumentation and bead conjugation methods.
- Analyze complex experimental data using appropriate statistical methods and software.
- Communicate with Scientific Solutions leadership and commercial sales teams during project life cycle stages.
- Resolve moderately complex problems requiring the application of standard procedures and techniques.
- Prepare detailed reports and presentations to communicate project progress to stakeholders.
- Use the approved ELN or controlled record system to maintain experimental records that are complete, contemporaneous, attributable, and traceable.
- Train and mentor junior staff in specific laboratory techniques and Good Documentation practices.
- Perform instrument calibrations/verifications as required.
- Draft and review SOPs, protocols, and project reports.
Qualifications
- Bachelor's Degree in Life Science (Biology, Biochemistry, Immunology or related discipline) with 5-7+ years of relevant experience, required.
- Master's Degree in Life Science with 2-3+ years of relevant experience, preferred.
- Ph.D. in Life Science with 1+ years of relevant experience, preferred.
- 2+ years experience performing protein, antibody, antigen, peptide, or other biomolecule conjugation in a GxP regulated environment, required.
- 2+ years experience with both bead-based conjugations and bead-based multiplexed assays, required.
- 2+ years experience with covalent based conjugations with diverse molecules for multiplexed assays in a regulated environment, required.
- Demonstrated experience executing work under controlled SOPs and protocols, maintaining traceable laboratory records, and complying with Good Documentation Practices and data-integrity requirements, required.
- Experience drafting and editing SOPs and working instructions for a GLP or GCP compliant laboratory.
- Experience with quality-system activities such as deviations, nonconformances, CAPA, change control, equipment qualification, method qualification or validation, audit support, or controlled reagent-release documentation.
- Experience characterizing immunoassay critical reagents using advanced analytical instrumentation for protein analysis.
- Use of electronic notebook software in a regulated environment.
- Experience working in a GLP or GCP environment.
- Experience in custom conjugation of molecules to beads or other solid phase surfaces.
- Ability to run multiplex immunoassays and conduct analysis of generated complex datasets.
- Proficient in protein biology, scientific principles and concepts.
- Mathematics and statistics aptitude.
- Proficient in Microsoft Word, Excel, and PowerPoint programs, Google Suite and assay data analysis software platforms.
- Ability to manage multiple projects simultaneously with proven time management and prioritization skills.
- Experience writing detailed reports and communicating project progress to stakeholders and customers.
- Excellent oral and written communication skills.
- Proficiency with ELN systems for real-time data capture, electronic signatures and audit trail management.
- Proficiency with Luminex xMAP instrumentation.
- Experience with biomarker assays and analysis in clinical trials.
- Experience with various protein analytical techniques such as FPLC, gel electrophoresis, UV-Vis and BLI.
- 30% Domestic and International travel.
