Purpose: The Bioanalytical Discovery and Development Sciences (BDDS) department within Johnson & Johnsons Preclinical Sciences & Translational Safety (PSTS) organization seeks a postdoctoral scholar to develop and validate an open amplification-coupled immunoaffinity platform for reliable quantification of low-abundance protein biomarkers using standard laboratory equipment. The role addresses key analytical gaps in next-generation therapeutics by delivering fit-for-purpose assays validation-ready documentation and transferable methods to support PK/TE/biomarker decisions and translational studies.

This hands-on role includes assay and reagent design systematic optimization analytical characterization benchmarking against orthogonal and commercial platforms and preparation of SOPs and tech-transfer materials. The postdoc will collaborate with PK/PD and translational teams communicate results through reports and publications and help expand the use of ultrasensitive assays in preclinical and clinical programs.

You will be responsible for:

• Leading the design development and optimization of ultra-sensitive amplification coupled immunoaffinity assays to enable reliable quantification of low abundance biomarkers (targeting sensitivity down to fg/mL) using standard laboratory instrumentation.
  
• Leading headtohead benchmarking of inhouse assays against orthogonal methods (LBA LCMS) and commercial ultrasensitive platforms to compare LOD/LLOQ precision sample requirements and techtransfer readiness.
  
• Collaborating with crossfunctional teams (PK/PD bioinformatics translational science and external partners) to integrate biomarker data into study design and decision making and to benchmark methods against orthogonal platforms.
  
• Producing and maintaining clear technical documentation including Standard Operating Procedures (SOPs) reagent quality control (QC) criteria validation plans/reports and method transfer packages to support reproducibility and technology dissemination.
  
• Communicating findings through written reports presentations and contributions to manuscripts; providing training and technical support for method transfer and laboratory adoption.
  

Qualifications/Requirements

Education:

• A PhD in Molecular Biology Bioengineering Biochemistry Immunology Analytical Chemistry or a related field is required.
  

Experience and Skills:

Required:

• Handson experience developing and optimizing immunoassays or nucleicacid amplification assays (e.g. qPCR digital PCR NGS) is required.
  
• Practical knowledge of ImmunoPCR proximity ligation/extension strategies or related amplificationcoupled immunoaffinity techniques is required.
  
• Strong molecular biology skills: PCR/qPCR assay design and optimization UMI/barcode strategies NGS library preparation workflows template purification and contamination control is required.
  
• Excellent written and verbal communication skills are required.
  
• Ability to work in cross-functional teams and present technical results to diverse audiences is required.
  

Preferred:

• Familiarity with antibody/protein engineering including optimizing affinity stability fragment design and tagging which directly enhances assay sensitivity and minimizes off-target binding is preferred.
  
• Prior experience measuring CNS biomarkers (e.g. tau species neurodegeneration biomarkers) or working with lowabundance protein analytes is preferred.
  
• Familiarity with bioanalytical platforms for ultrasensitive detection and an understanding of their strengths/limitations is preferred.
  
• Knowledge of PK/PD/TE study design as well as assay validation and how bioanalytical data informs translational decision making is preferred.
  
• Hands on experience with electronic lab notebook (ELN) systems and laboratory informatics platforms for experiment documentation reagent/inventory tracking and maintaining data integrity (e.g. commercial ELNs and signals style lab notebook systems) is preferred.
