We're looking for a Senior Formulation Scientist to join our Sterile Product Development (SPD) team, supporting the development and optimization of both sterile injectable products and peptide-based therapeutics. In this role, you'll lead formulation strategy and process development across a diverse product portfolio, supporting programs from early feasibility through commercial scale-up and lifecycle management.
You'll bring deep technical expertise in sterile injectable and peptide formulation development, working cross-functionally with Manufacturing Sciences & Technology (MS&T), Quality, and Regulatory teams to design robust, scalable formulations that meet CGMP and FDA 503B requirements. This is a senior technical role with room to shape formulation strategy, mentor junior scientists, and help expand our sterile and peptide portfolio.
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 (beyond-use date) 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.
Ph.D. in Pharmaceutical Sciences, Chemistry, Chemical Engineering, or a related field with 6–8+ years of industry experience, or B.S./M.S. with 8–10+ years of experience 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.
Strong understanding of peptide-specific degradation pathways and stability-indicating analytical methods.
Experience designing and executing stability studies in accordance with ICH Q1A(R2)/Q5C and USP/FDA 503B requirements.
Proficiency in analytical data interpretation (UPLC/HPLC, mass spectrometry, impurity profiling, and related peptide characterization methods).
Experience with formulation scale-up and technology transfer within CGMP environments.
Excellent technical writing, documentation, and cross-functional communication skills.
Experience evaluating third-party API/BUD data packages and providing technical recommendations as part of make-vs.-buy sourcing decisions.
Familiarity with long-acting injectable or novel peptide delivery technologies.
Experience with regulatory documentation and submissions (IND/NDA or 503B filings).
Prior leadership or mentorship experience within a formulation or analytical team.
Experience managing multi-site technology transfer (e.g., coordinating between development and manufacturing facilities).
Competitive salary & equity compensation for full-time roles
Unlimited PTO, company holidays, and quarterly mental health days
Comprehensive health benefits including medical, dental & vision, and parental leave
Employee Stock Purchase Program (ESPP)
401k benefits with employer matching contribution
Offsite team retreats
