Senior Scientist, Sterile Product Development; Onsite

Position: Senior Scientist, Sterile Product Development (Onsite)
Job Description

Role Overview :

The Sterile Product Development group develops parenteral dosage forms, including long-acting injectables and peptide drug conjugates across small molecules, peptides, and biologics from preclinical development through commercialization. Our teams develop robust, scalable drug product and delivery solutions through scientific understanding of formulation, drug–excipient interactions, delivery system performance, and manufacturing processes, with a focus on product quality, safety, efficacy, and patient-centric design.

The Senior Scientist is a hands-on individual contributor supporting the scientific development of long-acting injectables, peptide drug conjugates, and other parenteral formulations. The successful candidate will independently design and execute studies, interpret data, and provide formulation and process development recommendations within multidisciplinary teams. The role includes technical input and scientific leadership of defined experimental or development work streams, in alignment with project objectives and guidance from project leads.

Responsibilities:

Design, execute, and interpret formulation and process development studies for long-acting injectables and peptide drug conjugates, as well as conventional parenteral formulations. Evaluate approaches appropriate to each molecule and product, including polymer-based controlled-release systems and crystalline suspensions for long-acting injectables.

Provide scientific input to cross-functional teams on formulation, drug substance properties, delivery system performance, container/closure compatibility, manufacturability, and clinical in-use considerations. Take technical responsibility for assigned work streams, communicate findings and risks, and recommend next steps to project leads.

Design, conduct, and interpret studies to understand formulation stability and product performance for long-acting injectables and peptide drug conjugates, including release kinetics where relevant:

Drug–excipient and drug–polymer interactions

In vitro and in vivo performance relationships

Physical stability, solubility, aggregation, and particle size control, as appropriate to the formulation

Syringe ability, injectability, and device compatibility

Chemical stability of drug substances and formulated products, including peptide and conjugate integrity and formation of free drug in peptide drug conjugates

Support early‑ and late‑stage development programs, including:

Experimental evaluation and recommendation of scalable manufacturing processes for long-acting injectables and peptide drug conjugates

Characterization of formulation and process variables to support definition of design space

Support for clinical and commercial process scale‑up and validation

Technology transfer to GMP manufacturing facilities

Collaborate with Clinical, Non-Clinical, Quality, Regulatory, Manufacturing, and Engineering colleagues, contributing experimental data and scientific recommendations to:

Identify and characterize critical quality attribute and critical process parameters relevant to LAI and PDC quality, stability, and performance

Support clinical strategy through formulation design and risk mitigation

Contribute to CMC regulatory submissions and health authority interactions

Provide scientific leadership within defined work streams by developing experimental plans, troubleshooting technical challenges, interpreting results, and sharing recommendations. Offer informal technical guidance and knowledge sharing to colleagues without responsibility for people management or overall project delivery.

Maintain awareness of emerging LAI technologies and PDC formulation and delivery approaches; contribute scientific assessments and experimental…
