• Demonstrated expertise in PBPK, PBBM, pharmacometrics, mechanistic modelling, or model-informed drug development.
• Strong understanding of oral absorption, dissolution, permeability, biopharmaceutics, and pharmacokinetics.
• Experience with PBPK/PBBM modelling software such as Simcyp, GastroPlus, PK-Sim or similar platforms.
• Demonstrated ability to apply modelling to solve pharmaceutical development challenges.
• Strong written and verbal scientific communication skills.
• Evidence of scientific productivity through publications, presentations, technical reports or regulatory contributions.

Responsibilities

• Develop, verify, and apply PBBM and PBPK models using platforms such as Simcyp, GastroPlus or equivalent software.
• Support the prediction and assessment of oral absorption, food effect, bioavailability, formulation bridging, dissolution and particle size specifications, and virtual bioequivalence.
• Perform model calibration, sensitivity analyses, scenario testing, and uncertainty assessments to support project decisions.
• Collaborate with laboratory scientists to design and interpret in vitro studies supporting model development and verification.
• Support the development of clinically relevant dissolution methods and in vitro-in vivo links where appropriate.
• Communicate modelling outcomes through technical reports, project team presentations, regulatory documents, and scientific publications.
• Contribute to innovation in modelling methodologies, automation, and data-driven approaches, including AI/ML-enabled predictive tools where appropriate.

• Contribute to innovation in modelling methodologies, automation, and data-driven approaches, including AI/ML-enabled predictive tools where appropriate.

Required Qualifications

• PhD or MSc in Pharmaceutical Sciences, Biopharmaceutics, Pharmacokinetics, Pharmacometrics, Chemical Engineering or a related scientific discipline. For MSc candidates, substantial relevant industrial experience in PBPK, PBBM, pharmacometrics, mechanistic modelling or model-informed drug development is required.
• Demonstrated expertise in PBPK, PBBM, pharmacometrics, mechanistic modelling, or model-informed drug development.
• Strong understanding of oral absorption, dissolution, permeability, biopharmaceutics, and pharmacokinetics.
• Experience with PBPK/PBBM modelling software such as Simcyp, GastroPlus, PK-Sim or similar platforms.
• Demonstrated ability to apply modelling to solve pharmaceutical development challenges.
• Strong written and verbal scientific communication skills.
• Evidence of scientific productivity through publications, presentations, technical reports or regulatory contributions.

Preferred Qualifications

• Experience supporting regulatory submissions involving PBPK or PBBM analyses.
• Experience with virtual bioequivalence or clinically relevant dissolution specifications.
• Working knowledge of Python, R, MATLAB, or other scientific programming tools.
• Experience applying machine learning or data science approaches to pharmaceutical development.
• Experience across multiple drug modalities, including poorly soluble compounds, enabling formulations, peptides, or complex dosage forms
