We are seeking for hands‑on immunoassay developers for a new Analyte Detection Business Unit. If you have designed assays from scratch, selected and screened reagent pairs, and solved real development problems across ELISA, MSD, TR‑FRET, AlphaLISA, or related formats, we want to hear from you. Here’s what you’ll do:

• Design and execute bioconjugation strategies for labeling antibodies and other proteins with donor/acceptor fluorophores (NHS‑ester, maleimide, and related chemistries); optimize reaction conditions, purification, and labeling efficiency from first principles
• Develop homogeneous immunoassays (TR‑FRET, HTRF, AlphaLISA, MSD, and/or ELISA) for analyte detection; own the full development cycle from reagent selection and antibody pairing through format optimization and matrix validation
• Lead independent antibody screening campaigns to identify optimal capture/detection pairs; apply structured DOE approaches to optimize reagent concentrations, buffer formulations, and assay window
• Conduct routine assay validation experiments, including precision, accuracy, linearity, and range determination
• Prepare biological samples, reagents, and buffers according to SOPs
• Operate and maintain laboratory equipment, including plate readers, liquid handlers, and analytical instruments
• Independently diagnose and resolve assay performance failures; apply root‑cause analysis to reagent, buffer, and instrument variables and propose data‑driven corrective actions
• Support antibody screening and characterization activities
• Assist with benchmarking studies comparing assay performance to competitor products

• Maintain detailed, accurate, and organized laboratory notebooks documenting all experimental procedures and observations
• Analyze experimental data using Graph Pad Prism, Excel, or similar software
• Generate clear data summaries, graphs, and tables for internal reports and presentations
• Contribute to technical reports and validation documents
• Assist in drafting sections of SOPs and user manual protocols
• Ensure all documentation meets company quality standards and regulatory requirements

• Work collaboratively with Senior Scientist and other team members to support project timelines
• Participate in team meetings and provide updates on experimental progress
• Communicate experimental results and technical challenges effectively to the supervisor
• Actively seek learning opportunities to develop technical skills in bioconjugation and immunoassay development
• Support cross‑functional activities with Manufacturing, Quality, and Marketing teams as needed
• Participate in training programs to enhance scientific and professional development

• Adhere to all site employee health and safety (EHS) and IT security requirements
• Demonstrate and promote the company vision and values
• Maintain regular attendance and punctuality
• Conduct all activities in a safe and efficient manner
• Perform other duties as assigned
• Meet project deadlines and…
