Staff Scientist/Senior Staff Scientist

The Role:

We are seeking an accomplished and motivated DMPK scientist to join our team as a Staff Scientist/Senior Staff Scientist, DMPK.  This individual will play a pivotal role in driving our drug discovery efforts while also providing strategic support to our development-stage programs as needed.  The role offers a unique opportunity to work across the R&D continuum – from lead optimization through candidate nomination and IND-enabling studies – collaborating with innovative, cross-functional teams committed to developing safe and efficacious medicines for patients.  

The successful candidate will serve as a scientific leader within the DMPK function, providing subject matter expertise and program-facing support across small molecule discovery programs.  They will play a key role in ensuring continuity of DMPK strategies as programs advance into development and will contribute to functional strategy and capacity-building within the DMPK function.

Key responsibilities:

• Provide strategic and hands-on leadership of DMPK activities for multiple discovery-stage programs, including ADME/PK optimization, candidate nomination, and early development support
• Represent DMPK in cross-functional project teams and provide integrated ADME/PK guidance aligned with project objectives, timelines, and regulatory expectations
• Design, interpret, and report in vitro and in vivo studies (internal and CRO-based), including PK profiling, in vitro to in vivo correlations, and drug-drug interaction risk assessment
• Elucidate predictive ADME relationships, assess in vitro to in vivo correlations, PK/PD relationships, and perform human efficacious dose predictions using different approaches
• Guide development candidate selection through integration of ADME, PK/PD, physicochemical, and translational PK/PD modeling
• Author and review high-quality regulatory documents (e.g., INDs, IBs, and other regulatory filings) and contribute to regulatory strategy in collaboration with project and regulatory teams
• Collaborate closely with research and development colleagues and contribute to the growth of DMPK capabilities across the organization
• Provide scientific input to portfolio-level discussions and help align DMPK strategies with overall project and organizational goals

Qualifications:

• Doctorate degree in Pharmaceutical Sciences, Drug Metabolism, Pharmacokinetics, Biochemistry, or related discipline with 6+ years of relevant industry experience; or MS/BS degree with 10+ years of hands-on experience in DMPK within the pharmaceutical/biotech industry
• Proven track record of impactful scientific contributions to discovery and development programs (such as regulatory submissions and/or literature publications) demonstrating technical proficiency, independent thinking, and scientific creativity
• Deep understanding of DMPK science and its application to drug discovery and development, including a working knowledge of PK/PD modeling and human PK projection approaches
• Demonstrated technical proficiency, scientific creativity, strategic thinking, problem solving ability, and capable of independently designing and executing impactful hypothesis-driven experiments
• Experience supporting IND-enabling studies, including DDI risk assessments, human dose projection, and authoring of regulatory documents
• Up to date knowledge of technological and regulatory advances in the DMPK functional area
• Outstanding communication skills with demonstrated ability to make effective presentations in a broad range of settings, with strong collaboration and organizational skills
• The successful candidate will be motivated to discover new disease-modifying therapeutics for patients and enjoy working in a fast-paced dynamic team environment
