Senior Inhalation Scientist Jobs in California (NOW HIRING)

About Avalyn:
Avalyn aims to transform the treatment paradigm for pulmonary fibrosis and other serious, rare respiratory diseases. The company is advancing optimized inhaled formulations of established antifibrotic medicines designed to deliver drug directly to the lungs, enhance local efficacy, and reduce systemic side effects. Avalyn's AP01 program is an optimized inhaled formulation of pirfenidone currently being evaluated in MIST, a global Phase 2b clinical trial in patients with progressive pulmonary fibrosis (PPF). AP01 has demonstrated encouraging safety and clinical activity across Phase 1b and an ongoing, multi-year open-label extension trial, with long-term data supporting the potential to preserve lung function while improving tolerability relative to historical oral pirfenidone. Avalyn's AP02 program is an optimized inhaled formulation of nintedanib currently being evaluated in AURA, a global Phase 2 clinical trial in patients with idiopathic pulmonary fibrosis (IPF). Avalyn is also advancing AP03, an inhaled fixed-dose combination of pirfenidone and nintedanib, designed to deliver multiple antifibrotic mechanisms through a single lung-targeted platform. By leveraging its proprietary drug-device approach and deep expertise in rare respiratory disease development, Avalyn aims to establish a new standard of care in pulmonary fibrosis through inhaled, lung-targeted therapies.

• Analyze experimental data and prepare technical reports, presentations, and development summaries.
• Ensure laboratory activities are conducted in compliance with applicable quality and safety requirements.
• Maintain laboratory equipment and coordinate analytical testing as required.
• Assist in hiring, onboarding, and managing a laboratory technician to execute formulation development, preformulation, aerosol testing, and characterization studies.

Product Development

• Collaborate with cross-functional development teams to advance inhaled drug products through clinical development.
• Support technology transfer activities to manufacturing sites and CDMOs.
• Participate in process development, scale-up activities, engineering batches, and clinical manufacturing campaigns.
• Support CMC documentation for regulatory submissions, including INDs, IMPDs, briefing documents, and other technical reports.

Technical Leadership

• Provide scientific expertise in formulation development and aerosol science across Product Development.
• Stay current with advances in inhalation technologies and pharmaceutical formulation science.
• Present technical findings to project teams and senior management.

Qualifications:

• Ph.D. in Pharmaceutical Sciences, Chemical Engineering, Chemistry, Materials Science, or a related scientific discipline is required.
• A minimum of 8 plus years of industry experience in pharmaceutical formulation development following completion of a Ph.D. is required.
• Experience developing inhaled pharmaceutical products is highly preferred.
• Deep understanding of aerosol science and pulmonary drug delivery is preferred.
• Hands-on experience with solution and dry powder inhalation formulations is desirable
