Job summary

Hims & Hers, a leading health and wellness platform, seeks a Senior Formulation Scientist to advance sterile injectable and peptide product development from early feasibility to commercial scale. You will lead strategy, mentor scientists, and collaborate with MS&T, Quality, and Regulatory teams to ensure CGMP compliance and robust formulations.

You will design pre-formulation studies, develop stability programs per ICH Q1A(R2)/Q5C, and support tech transfer across sites.

Qualifications

• Ph.D. in Pharmaceutical Sciences, Chemistry, Chemical Engineering, or related field with 6–8+ years of industry experience, or B.S./M.S. with 8–10+ years in sterile injectable product development, including direct peptide formulation work.
• Hands-on experience formulating peptide therapeutics for parenteral administration (solutions, suspensions, or lyophilized products).
• Demonstrated experience developing sterile injectable (parenteral) drug products, with direct involvement in formulation design, fill/finish considerations, and container-closure selection.

Responsibilities

• Lead formulation and process development for sterile injectable and peptide-based products, including solutions, suspensions, and long-acting injectable formats.
• Design and execute pre-formulation, excipient compatibility, and forced-degradation studies specific to peptide stability, including oxidation, deamidation, aggregation, and hydrolysis pathways.
• Develop and optimize stability programs aligned with ICH Q1A(R2) and Q5C, including BUD justification for compounded and sterile products.
• Provide technical input into peptide API selection, characterization, and make-vs.-buy evaluations in partnership with cross-functional stakeholders.
• Design lab- and pilot-scale studies to assess formulation feasibility, freeze-thaw stability, container-closure compatibility, and process robustness.
• Author and review technical reports, stability protocols, and formulation development summaries to support regulatory filings and internal decision-making.
• Partner with MS&T, Quality, and Operations to ensure smooth technology transfer of sterile and peptide formulations from lab to commercial manufacturing across sites.
• Support OOS/OOT investigations and CAPA implementation related to sterile and peptide product stability and quality.
• Provide scientific mentorship to formulation scientists and technicians, and contribute to SOP development and gap analyses (e.g., ICH stability guideline alignment).
• Stay current on peptide delivery technologies, degradation science, and analytical methods, and evaluate new technologies for lifecycle management.
