Senior Engineer III, ADME

Assay Development & Implementation

• Design, develop, optimize, and validate a wide array of high-throughput in vitro ADME assays (e.g., solubility, MDCK permeability, plasma protein binding, microsomal stability, hepatocyte stability, and CYP inhibition/induction).
• Automation and Screening: Experience working with automated liquid handlers such as Hamilton, Lynx, Bravo, and Formulatrix.

Data Analysis & Reporting

• Develop and perform mass spectrometry (LC-MS/MS, acoustic ejection mass spectrometry, or similar) analysis of samples from ADME assays. Responsibilities will include method development and troubleshooting.
• Ensure proper sample preparation and management for high-throughput analysis.
• Analyze, interpret, and report complex ADME data, including calculating key pharmacokinetic parameters.
• Present results and provide expert recommendations to medicinal chemists and project teams to inform go/no-go decisions.

Quality & Compliance

• Maintain detailed and accurate laboratory records, SOPs, and electronic notebooks.
• Ensure all laboratory activities comply with internal quality standards and safety regulations.

Operational ownership & risk management

• Lead day-to-day operations of the ADME team
• Build and maintain “buttoned-up” SOPs, runbooks, checklists, and QC dashboards for all established assays.

Cross-functional partnership

• Collaborate with computational and data teams on metadata schemas, QC metrics, and analysis-ready outputs.
• Work closely with program leads to scope work, set expectations, and communicate progress and risks.
• Contribute to portfolio and capacity planning, including scenarios for large campaigns.

Leadership, mentoring, and training

• Provide technical leadership and day-to-day guidance for scientists on ADME workflows.
• Contribute to the Datapoints skill matrix by defining training levels, shadowing plans, and up-leveling team members on key assays
• Document methods, “tips & tricks”, and troubleshooting guides; lead trainings and onboarding sessions.
