Scientist I/II, Characterization and Composition Analysis

What you'll do

• Develop and validate XRF, EDS, and WDS methods, calibrations, and quality-control procedures; prepare standards, measure samples, and interpret spectra.
• Investigate anomalous or out-of-specification results, assess data validity, and maintain instrument readiness and documentation.
• Build and maintain tested analyzer software and automated workflows for spectral processing, quantification, data ingestion, metadata, provenance, and quality control.

What they ask for

• PhD in Materials Science, Chemistry, Physics, Engineering, or a related field, or M.S. with equivalent hands-on characterization experience.
• Hands-on experience with XRF, SEM-EDS, and WDS for elemental analysis, including their physical principles and common sources of error.
• Experience preparing standards, validating methods, troubleshooting measurements, and applying calibration, quantification, spectral interpretation, and data-quality control.
• Experience writing analysis notebook and maintaining shared, tested code in a version-controlled codebase; proficiency with Python or an equivalent coding environment.

Nice to have

• Experience with EPMA or related elemental microanalysis workflows.
• Experience with broader characterization methods, spectral analysis tools, analytical-instrument calibration/QC, or automated analysis pipelines.
