BIOANALYTICAL SCIENTIST

Summary

We are seeking a highly skilled and motivated Bioanalytical Scientist with senior expertise in method development for ligand binding assays (LBAs). This role involves designing, developing new bioanalytical assays, optimization and testing LBA-based assays for RNA therapeutics and related novel modalities to support non-regulated pharmacokinetic (PK), toxicokinetic (TK), and ADA with minimal guidance. The ideal candidate will possess strong technical proficiency, independent problem-solving skills, and a collaborative mindset. This position is onsite and lab-based, involves approximately 90% laboratory work and 10% office-based tasks. The candidate must be comfortable working in a fast-paced environment that requires attention to detail and adaptability and change of priorities.

Responsibilities

• Method Development:
• Design and develop new assays from scratch.
• Optimize ligand binding assays (e.g. MSD, ELISA) with a focus on sensitivity, specificity, linearity, reproducibility and robustness.
• Independently troubleshoot assay performance issues and implement improvements.
• Write a detailed protocol of the methods developed to use in sample analysis.
• Data Analysis & Reporting:
• Document the experimental design and execution in ELN
• Analyze experimental data using appropriate statistical tools.
• Prepare PowerPoint presentation and summarize results in technical reports, when needed.
• Present findings to internal teams and external stakeholders.
• Collaboration & Training:
• Work closely with cross-functional teams, including pharmacology and medicinal chemistry.
• Provide procedural training and mentorship to junior scientists.
• Support colleagues on sample analysis as the need arises.
  

Requirements

• Ph.D. in Biochemistry, Biology, Analytical Chemistry, or a related field with at least 1-3 years of experience as a post-doctoral fellowship or scientist in biotech/pharma.
• Proficiency in troubleshooting and optimizing bioanalytical methods.
• Advanced knowledge and hands-on experience of ligand binding assay formats (e.g., ELISA, Solid).
• Previous experience developing bioanalytical assays (e.g. ELISA, MSD) for quantification of antisense oligonucleotides or siRNA is a plus
• Experience with bioanalytical instruments such as LC/MS is a plus
• Familiarity with bioanalytical method validation guidance (e.g. FDA,EMA, ICH M10)
• Experience with lab automation technologies.
• Strong technical writing skills for documentation and reporting.
• Proven ability to manage multiple projects simultaneously.
• Effective communication skills for presentations and team collaboration.
