Process Development Senior Scientist – Drug Product Technologies

What You Will Do

In this vital role you will join the Pre‑Pivotal Drug Product Technologies group, responsible for early‑stage drug product development across diverse modalities, with a strong emphasis on antibody‑drug conjugates (ADCs), as well as monoclonal antibodies, multispecifics and other biologic modalities. The role involves designing and developing liquid and lyophilized formulations; evaluating critical quality attributes (CQAs); establishing robust, scalable fill/finish processes for complex biologic drug products; and authoring and supporting high‑quality regulatory submissions.

The ideal candidate will bring hands‑on experience in ADC drug product formulation and drug product process development, including a mechanistic understanding of linker‑payload attributes, stability/process‑relevant degradation pathways, and analytical strategies used to characterize ADC CQAs. You will integrate formulation, analytical, and process data to guide product design, apply cutting‑edge technologies (including AI/ML), and collaborate cross‑functionally to deliver high‑quality, stable, and manufacturable drug products for clinical development in a fast‑paced environment.

Key Responsibilities

• Work effectively in a fast‑paced, matrixed environment, collaborating across process development, research, regulatory, and manufacturing teams to advance programs and communicate technical recommendations to both scientific peers and leadership.
• Plan and execute formulation and fill/finish process studies for early‑stage programs.
• Develop and characterize liquid and lyophilized formulations for biologics, with particular emphasis on ADC drug product formulation, handling, and lab‑scale sterile filling.
• Build process understanding across unit operations to support scalable drug product development.
• Evaluate in‑use compatibility and drug product stability under clinical conditions.
• Investigate ADC‑ and biologics‑relevant CQAs to inform formulation and process design decisions.
• Leverage high‑throughput tools for formulation screening and processability assessments.
• Identify and address technology gaps impacting ADC stability, linker‑payload integrity, protein‑excipient interactions, and process‑related stress responses.
• Apply machine learning, AI, and data science to predictive modeling, workflow acceleration, and decision‑making.
• Ensure development approaches are phase‑appropriate, from discovery through clinical manufacturing.
• Author technical documents, control‑strategy inputs, risk assessments, IND/CTA regulatory sections, and tech transfer packages.
• Support internal and external technology transfer activities, including collaboration with CMOs/CDMOs, batch record review, process fit assessments, person‑in‑plant support, and troubleshooting during manufacturing campaigns.
• Present findings to internal/external stakeholders and participate in cross‑functional teams.

What We Expect Of You

The Scientific professional we seek is an individual with these qualifications.

Basic Qualifications

• Doctorate degree PhD OR PharmD OR MD [and relevant post‑doc where applicable]
• OR
• Master’s degree and 3 years of Scientific experience

Preferred Qualifications

• PhD in Pharmaceutics, Biotechnology, Biochemistry, or related field with 2–4 years of post‑doc or industry experience.
• Proven experience in formulation development, stability testing, and fill/finish operations for biologics; direct ADC drug product formulation experience is strongly preferred.
• Demonstrated understanding of ADC drug product development considerations, including linker‑payload stability, drug‑to‑antibody ratio, free drug or payload degradation, quality attributes, and product/process comparability.
• Experience integrating formulation, stability, and analytical data to advance ADC candidates from discovery or preclinical development into clinical manufacturing is highly desirable.
• Strong foundation in analytical and biophysical techniques relevant to ADCs and biologics.
