The scope of the daily responsibilities for this position includes, but is not limited to, developing bioanalytical methods, quantitating drug candidates and their metabolites, endogenous biomarkers in biological matrix (e.g. blood, plasma, tissues, tumor, CSF, etc.), and reporting high-quality data. The successful candidate will have extensive experience in bioanalytical method development and sample analysis using LC-MS/MS and other analytical techniques.

The Opportunity

Provide bioanalytical support for in vivo PK, PK/PD, efficacy studies, non-GLP toxicology and in vitro studies

Conduct bioanalytical method development and qualification to support drug, metabolite and biomarker analysis

Independently develop LC-MS/MS methods to quantitate small molecules in in vitro and in vivo samples and execute sample analysis

Independently operate, troubleshoot and maintain LC-MS/MS and analytical equipment

Participate in multidisciplinary project teams and partner closely with other departments, including pharmacology, chemistry and biology to understand bioanalytical needs for PK support

Maintain accurate and detailed laboratory notebooks

Ability to think and plan strategically, and excellent interpersonal skills and ability to work in a team environment

What You’ll Bring

BS or equivalent with 10 or more years’ relevant experience, or MS with 6 or more years’ relevant experience, or PhD with up to 4 years’ relevant experience working in a discovery setting using quantitative LC-MS/MS within a pharmaceutical or biotechnology company

Demonstrated experience in small molecule biomarkers as well as drug candidate bioanalytical assay development/sample quantitative analysis in complex biological matrices using LC-MS/MS

Proven experience running and troubleshooting LC-MS/MS-based quantitative workflows on Sciex platforms and software

Excellent written, verbal communications and interpersonal skills to collaborate with internal and external partners in a matrix environment

Ability to work in a fast-paced, collaborative environment and manage multiple priorities

Preferred Qualifications

Experience in targeted protein degradation or heterobifunctional degrader platforms

Extensive experience with H/UPLC and mass spectrometry

Extensive experience with sample analysis to support PK, PK/PD, efficacy, distribution, metabolism, and non-GLP toxicology studies

Extensive experience in developing and implementing quantitative LC-MS/MS based assays for small molecules in complex biological matrices

Excellent oral and written communication skills

Experience reviewing result files and reports from bioanalytical contract research organizations

Experience with maintaining detailed up to date lab notebooks and technical documentation

Location: Onsite – Brisbane, CA

Salary Range: $141,500 - $175,600

The posted range applies to roles based in the San Francisco Bay Area and reflects local market conditions. Where an offer lands within that range depends on the candidate’s relevant experience, technical expertise, and how their background aligns with the role’s requirements.
