Advanced Staining Operations

• Independently perform immunohistochemistry (IHC), immunofluorescence (IF), and in situ hybridization (ISH) staining procedures according to laboratory SOPs.
• Prepare, stain, and process FFPE tissue sections while maintaining specimen integrity and traceability.
• Perform routine and advanced staining workflows to meet client turnaround time expectations.
• Assist with routine IHC production as laboratory workload requires.

Assay Development & Optimization

• Research scientific literature to identify and evaluate antibodies, biomarkers, and staining methodologies for client projects.
• Develop, optimize, and validate new IHC, IF, ISH, and multiplex immunofluorescence (mIF) assays.
• Design experiments to optimize staining conditions, antibody concentrations, antigen retrieval methods, and detection systems.
• Analyze experimental results and recommend protocol improvements.

Validation & Quality Assurance

• Perform biomarker, assay, reagent, and equipment validation studies.
• Troubleshoot staining inconsistencies and identify root causes of quality issues.
• Review stained slides with pathologists to ensure assay performance and staining quality.
• Prepare validation reports documenting assay performance and quality outcomes.
• Maintain compliance with laboratory quality standards and documentation requirements.

Project Leadership & Client Support

• Serve as the technical lead for assigned client projects.
• Lead project update meetings and communicate progress with internal teams and external clients.
• Coordinate project timelines to ensure deliverables are completed on or ahead of schedule.
• Support Advanced Immuno Research (AIR) projects by coordinating laboratory activities and scientific documentation.
• Assign AIR projects through Monday.com and monitor project progress.

Laboratory Operations

• Maintain organization of the Advanced Staining laboratory.
• Monitor inventory levels and coordinate ordering of laboratory reagents, antibodies, consumables, and supplies.
• Ensure laboratory equipment is maintained, calibrated, and operating properly.
• Support continuous improvement initiatives to increase laboratory efficiency, quality, and productivity.

Collaboration & Mentorship

• Collaborate closely with Histology, Digital Pathology, Quality, and Pathology teams.
• Mentor and train junior laboratory staff on staining techniques, laboratory procedures, and best practices.
• Contribute to process improvement initiatives that enhance laboratory performance and client satisfaction.

Qualifications
