About The Position

The Discovery Bioanalytical Leader, reporting into the Head of DMPK, provides scientific, operational, and people leadership for bioanalytical activities supporting the discovery research of peptide biologic therapeutics. This role is responsible for developing, implementing, and executing bioanalytical strategies that are fit-for-purpose and support the generation of robust pharmacokinetic (PK), in vivo nonclinical PK/PD, anti-drug antibody (ADA), and related bioanalytical data. These data enable reagents and/or tool molecules identification & testing, exploratory in vivo studies, lead optimization, candidate selection, and progression into non-GLP toxicology studies. Working in a highly collaborative, fast-paced biotechnology environment, this individual will combine hands-on laboratory leadership with strategic oversight of outsourced bioanalytical activities while leading a small team of bioanalytical scientists. The successful candidate will serve as the company's technical expert in mass spectrometry and ligand binding assays, providing scientific direction, mentorship, and supervision to team members while partnering closely with Discovery Biology, Pharmacology, Toxicology, and CMC teams.

Requirements

Ph.D. in Pharmaceutical Sciences, Analytical Chemistry, or a related scientific discipline.
Minimum of 6 years of relevant experience in bioanalysis within biotechnology, pharmaceutical, or CRO environments.
Demonstrated experience leading, mentoring, and developing scientific staff in a laboratory environment.
High level of expertise in LC-MS/MS and ligand binding (LBA) assays for the bioanalysis of peptide, biologic, and/or small molecule drug discovery programs
Hands-on experience with assay development, optimization, troubleshooting, and validation.
Strong experience developing and executing bioanalytical assays supporting pharmacokinetic (PK) and anti-drug antibody (ADA) studies.
Hands-on experience performing non-compartmental pharmacokinetic (NCA) analyses and interpreting PK parameters using industry-standard software (e.g., Phoenix WinNonlin) to support discovery and early development decision-making.
Experience managing external CROs and outsourced bioanalytical studies.
