The Role

We’re seeking an experienced Director, Packaging Engineering to lead all aspects of packaging process development, qualification, validation, launch readiness, and commercial supply for Loyal’s small molecule, oral solid dosage (OSD) products. This role is responsible for packaging operations across the entire product lifecycle — from development through commercial execution — and will drive CDMO selection and management, packaging process development, packaging line readiness, and packaging validation (IQ/OQ/PQ).

You will ensure that Loyal’s packaging systems are robust, compliant, and ready to support product launch and ongoing commercial supply.

The ideal candidate brings deep expertise in OSD packaging engineering, strong experience with external packaging and manufacturing partners, and the ability to deliver packaging strategies and solutions that meet regulatory, technical, operational, and commercial requirements.

Experience with veterinary products is a plus but not required. This role reports to the Vice President, Manufacturing.

Responsibilities

• Lead packaging process development, scale‑up, and optimization for OSD drug products.

• Drive CDMO/CMO selection, including technical evaluations, audits, contracting, and governance for packaging operations.

• Develop and refine packaging processes, ensuring robustness, manufacturability, and compliance with regulatory and product requirements.

• Lead packaging qualification and validation (IQ/OQ/PQ) for launch and commercial readiness.

• Oversee packaging launch readiness, including artwork, labeling, serialization, child‑resistant/senior‑friendly requirements, packaging components, and distribution‑related packaging needs.

• Establish and oversee commercial packaging operations, ensuring efficiency, compliance, and long‑term supply continuity.

• Author and contribute to packaging‑related sections of regulatory submissions (Module
3), including container‑closure system documentation, packaging process descriptions, and responses to regulatory queries.

• Support or participate in PAIs and other regulatory interactions related to packaging.

• Conduct and oversee packaging component qualification, compatibility studies, and packaging‑related stability evaluations.

• Troubleshoot packaging issues, conduct root‑cause investigations, and lead CAPAs.

• Drive continuous improvement across packaging operations, materials, and systems.

• Collaborate cross‑functionally with Manufacturing, Quality, Supply Chain, Regulatory, Formulation, and Analytical Development to ensure packaging readiness across all development and commercial stages.

About You

• Bachelor’s, Master’s, or PhD in Packaging Engineering, Chemical Engineering, Mechanical Engineering, Materials Science, or a related field.

• 10+ years of experience in pharmaceutical or biopharmaceutical packaging engineering, with significant experience supporting commercial or late‑stage OSD products.

• Deep expertise in small‑molecule, oral solid dosage packaging, including bottling, blister packaging, labeling, serialization, and container–closure systems.

• Proven success leading packaging process development, scale‑up, qualification, and validation (IQ/OQ/PQ).

• Strong experience with CDMO/CMO selection, technical transfer, and day‑to‑day management for packaging operations.

• Experience supporting commercial packaging operations, including launch readiness and ongoing supply.

• Demonstrated ability to author packaging sections of regulatory submissions (e.g., Module
3) and…
