Senior Scientist, Analytical Chemistry
About the role
Osmo is a digital olfaction company dedicated to enhancing human life through the application of automation and AI/ML to olfactory intelligence. This role is part of a team focused on advancing the capabilities of our fragrance discovery engine and machine learning infrastructure.
Key Responsibilities
Own the end-to-end analytical strategy for specific GC-MS-based programs, including method design, validation frameworks, and data quality standards for both targeted and untargeted analyses.
Define and evolve sample preparation methodologies for headspace, liquid-phase, and solid-phase extraction of fragrance compounds from complex matrices and consumer products.
Maintain and improve Osmo’s high-throughput analytical pipeline, ensuring data integrity, reproducibility, and compatibility with downstream machine learning workflows.
Partner deeply with the Platform and ML teams to shape how analytical data is structured, stored, and leveraged computationally, acting as the chemistry-side technical owner of the data interface.
Determine methods and procedures for new analytical assignments independently, coordinating execution across team members and collaborating functions as needed.
Enforce and hold teammates and colleagues to high standards of scientific rigor and data quality.
Mentor and technically develop junior and mid-level scientists, establishing best practices, reviewing work for scientific integrity, and elevating the team’s overall analytical capability.
Write, edit, and audit analytical and experimental protocols.
Serve as an internal expert resource and external-facing collaborator for analytical chemistry questions across Osmo’s scientific and commercial programs.
Required Qualifications
PhD in Analytical Chemistry, Flavor/Fragrance Chemistry, Atmospheric Chemistry, Cosmetic Chemistry, or a related field with 5+ years of post-degree experience, or equivalent combination of advanced degree and demonstrated technical leadership.
Deep, hands-on expertise in GC-MS method development and validation across both targeted quantitation and untargeted profiling.
Familiarity with MassHunter Qual/Quant or comparable analysis platforms.
Advanced proficiency in sample preparation techniques for complex matrices, including LLE, SPE, headspace, and SPME, with the ability to design novel approaches for non-standard substrates.
Demonstrated experience operating with high autonomy in defining analytical scope, setting timelines, and coordinating others to execute without close supervision.
Proven ability to set technical direction for a team or program, including authoring or redesigning SOPs, establishing QC frameworks, or leading analytical platform decisions.
Excellent cross-functional communication skills, with a track record of translating complex analytical requirements into actionable plans for non-chemistry stakeholders (e.g., ML engineers, product teams).
