Scientist/Senior Scientist, Analytical Chemistry

The future must be created.

01 THE ROLE

Chemistry is the invisible layer under every critical system, and the supply chain behind it has become a weapon. Ohr makes the molecules that matter most, from the atom up: energetics, propellants, rare-earth extractants and the ignition chemicals already in production today.

As a Scientist or Senior Scientist in Ohr's analytical chemistry R&D group, you'll own method development, sample analysis, and structure elucidation. You'll work closely with biology and chemistry teams to move products from lab scale to pilot scale and troubleshoot analytical challenges across a range of projects.

THE KIND OF PEOPLE THIS WORK DEMANDS

Our mission demands more than great science. It requires a particular kind of team — visionary builders, hustlers, scientists, operators. Together, we carry both the technical depth to make the chemistry work and the commercial instinct to make the business thrive. People are our engine. Collaboration is our multiplier.

02 WHAT YOU'LL DESIGN AND BUILD

- Develop, optimize, and validate HPLC and GC methods for a wide variety of sample types, including biological matrices and synthetic organic reaction products and intermediates.
- Perform structure elucidation and characterization of synthetic organic compounds using LC-MS, GC-MS, NMR, and other spectroscopic techniques.
- Operate, calibrate, troubleshoot, and maintain analytical instrumentation (HPLC, GC, GC-MS, LC-MS, ICP-MS, etc.).
- Interpret complex analytical data and prepare clear, detailed technical reports and summaries.
- Author and review SOPs, test methods, and validation protocols.
- Collaborate cross-functionally with synthetic chemists, biologists, and process engineers to resolve analytical issues and support project timelines.
- Maintain accurate laboratory records.
- Source consumables and reference materials, and manage instrument service relationships with vendors.

03 WHAT YOU BRING WITH YOU

- Bachelor's degree in Chemistry, Biochemistry, or a related scientific discipline. A Master's or PhD is a plus and may offset the experience requirement.
- 2–10 years of hands-on analytical chemistry experience in an R&D or industrial laboratory setting.
- Strong, demonstrated expertise in HPLC and GC method development, validation, and troubleshooting.
- Solid understanding of chromatographic theory and separation science.
- Strong technical writing and data interpretation skills
- Ability to work independently, manage multiple concurrent projects, and prioritize under deadlines.
- Excellent communication and cross-functional collaboration skills.

STRONG PLUS

- Experience with gas-phase analysis techniques by GC (e.g., headspace GC, TCD).
- Experience with mass spectrometry (LC-MS and/or GC-MS) for compound identification and structure confirmation.
- Experience characterizing heterogeneous catalysts (e.g., BET surface area, chemisorption, TPR/TPD, XRD, or related techniques).
- Experience with Agilent chromatography data software (ChemStation, MassHunter, or OpenLab).
- Experience analyzing fuels or petroleum-derived products (e.g., RP-1, jet fuels, or similar hydrocarbon streams).
- Familiarity with additional analytical techniques such as Raman, FTIR, UV-Vis, ICP-MS, or flash chromatography.
- Experience working across both biological and synthetic organic chemistry programs in the same role.

WORK ENVIRONMENT

- Laboratory-based role requiring safe handling of hazardous materials, solvents, and potentially reactive compounds.
- May require occasional off-hours availability for time-sensitive analyses.
- Some travel may be required depending on project needs (typically under 1%).
