Company

hirify.global develops pharmaceutical products and technologies across small molecules, peptides, biologics, and sterile drug delivery.

What you will do

• Design, execute, and interpret formulation and process development studies for long-acting injectables, peptide drug conjugates, and conventional parenteral formulations.
• Evaluate controlled-release systems, crystalline suspensions, drug–excipient and drug–polymer interactions, stability, aggregation, particle size, injectability, syringeability, and device compatibility.
• Support scalable manufacturing process development, design-space definition, clinical and commercial scale-up, validation, and technology transfer to GMP facilities.
• Identify critical quality attributes and critical process parameters, contribute to clinical strategy and risk mitigation, and support CMC submissions and health authority interactions.
• Lead defined technical workstreams by planning experiments, troubleshooting challenges, interpreting data, communicating risks, and recommending next steps without formal people-management responsibility.
• Contribute to capability development, external collaborations, patents, publications, presentations, and scientific activities related to sterile product development.

Requirements

• Ph.D. with 0 years of industry experience, or M.S. with 4+ years of industry experience in Pharmaceutics, Pharmaceutical Sciences, Chemical Engineering, Biochemical Engineering, Chemistry, Materials Science, or a related discipline.
• Strong scientific foundation and hands-on or academic experience in parenteral formulation or process development, including relevant experience with long-acting injectables, sustained-release formulations, peptides, or drug conjugates.
• Experience applying Quality by Design principles and Design of Experiments approaches to formulation and process development.
• Experience providing experimental or technical support for process scale-up, validation, or technology transfer involving sterile injectable products.
• Ability to independently plan and execute studies, interpret complex data, communicate clear scientific recommendations, collaborate across functions, and provide technical leadership within a defined workstream.

Nice to have

• Experience with polymer depots, microspheres, nanosuspensions, or in situ forming long-acting injectable systems, particularly across both LAI and peptide or drug-conjugate development.
• Working knowledge of CMC regulatory expectations and scientific documentation for sterile parenteral development and commercial submissions.
• Experience with controlled-release mechanisms, formulation-performance relationships, drug–polymer and drug–excipient interactions, and peptide or conjugate integrity.
• Experience with device–drug product integration, including prefilled syringes and relevant delivery systems.
• Understanding of clinical and patient-centric considerations such as dosing interval, injection volume, and administration route.
• Experience supporting global regulatory filings and health authority interactions, plus contributions to publications, patents, or external scientific collaborations.
