The Opportunity We are seeking a Laboratory Technician, ICP-MS to join our Nanoscience team. This role will support the team’s analytical and experimental work through the operation, maintenance, and application of inductively coupled plasma mass spectrometry (ICP-MS), with a particular focus on reliable trace-element analysis and high-quality experimental data.

The ideal candidate is hands-on, detail-oriented, and comfortable working in a fast-paced R&D laboratory environment. This person will work closely with scientists and engineers across the Nanoscience team to prepare samples, execute analytical methods, maintain laboratory instrumentation, and ensure the quality and reproducibility of analytical results.

Operate ICP-MS instrumentation for routine and experimental trace-element analysis.

Prepare samples, standards, blanks, and calibration solutions using appropriate clean-lab and contamination-control practices.

Perform instrument calibration, tuning, quality-control checks, and routine system suitability testing.

Process, review, and document analytical data, including calibration curves, QC results, detection limits, and sample results.

Maintain accurate laboratory notebooks, instrument logs, sample records, and experimental documentation.

Manage ICP-MS consumables, standards, reference materials, gases, and other laboratory supplies.

Support general laboratory operations, including preparation of reagents and solutions, equipment upkeep, inventory management, and laboratory organization.

Follow laboratory safety procedures and established protocols for handling acids, chemicals, samples, and laboratory waste.

Contribute to the development of SOPs, analytical procedures, and laboratory best practices.

Support additional analytical and Nanoscience laboratory activities as priorities evolve.

Associate’s or Bachelor’s degree in chemistry, analytical chemistry, materials science, nanoscience, chemical engineering, or a related scientific discipline, or equivalent hands-on laboratory experience.

Experience working in a chemistry, analytical, materials, or research laboratory.

Experience preparing samples, standards, reagents, and solutions using quantitative laboratory techniques.

Comfort working with laboratory instrumentation and learning new analytical methods.

Experience with trace metals or elemental analysis.

Familiarity with analytical QA/QC practices, including blanks, spikes, duplicates, internal standards, calibration verification, and certified reference materials.

Experience working in an R&D, startup, or rapidly evolving laboratory environment.

We celebrate diversity and are committed to creating an inclusive environment for all employees.
