Job Title:
Senior Chemist, Technical Laboratory OperationsJob Description:
The Role
Entegris is currently seeking a Senior Chemist, Technical Laboratory Operations to join our Analytics & Metrology, Trace Metals team. This position will be based in our Burnet facility.
In this role, you will be responsible for ensuring reliable, high-throughput analytical metrology in a production laboratory supporting semiconductor-grade precursors and wet chemical cleans. This role focuses on measurement execution, data quality, contamination control, and instrument performance to ensure materials consistently meet stringent semiconductor specifications. The position plays a key role in maintaining analytical readiness, resolving production-related issues, and ensuring measurement systems remain stable, precise, and audit-ready.
What You’ll Do
Perform and oversee routine trace metals analysis of semiconductor chemicals using ICP-MS and ICP-OES
Analyze and interpret ultra-trace metal impurity data at ppb–ppt levels for production release
Review and approve analytical results, ensuring conformance to tight product specifications
Ensure consistent achievement of detection limits and sensitivity requirements for key metallic contaminants
Conduct all work in cleanroom or clean-controlled environments, following strict contamination control protocols
Enforce best practices for ultra-clean sample handling, preparation, and transfer
Minimize environmental and cross-contamination sources (labware, reagents, gases, operator technique)
Ensure proper gowning, materials handling, and workflow discipline aligned to semiconductor standards
Serve as primary technical expert for ICP-MS and ICP-OES systems in a production environment
Maintain instrument performance including tuning, calibration, interference control, and drift management
Perform advanced troubleshooting of sensitivity loss, background contamination, and instrument instability
Ensure system suitability, QC checks, and performance benchmarks are consistently met
Support preventive maintenance and coordinate repairs to maximize instrument uptime
Monitor and maintain measurement system stability, precision, and reproducibility
Apply statistical tools (SPC, trending, control charts) to detect shifts in analytical performance
Investigate out-of-spec (OOS), out-of-trend (OOT), and excursion events related to metals analysis
Ensure methods remain fit-for-purpose without introducing unnecessary variability
Support real-time production decisions through rapid and reliable metals data
Lead analytical investigations into contamination events affecting product quality or customer returns
Partner with manufacturing and quality teams to identify root causes of metal contamination
Provide clear technical interpretation of results to support dispositioning decisions
Ensure compliance with semiconductor customer requirements, ISO 17025 (if applicable), and SEMI standards
Maintain and follow SOPs, test methods, and data review procedures specific to metals analysis
Ensure full adherence to data integrity principles (ALCOA+)
Support audits and customer inquiries related to trace metals measurement capability
Evening and weekend support as needed to support lab chemists and laboratory operations
What We Seek
Bachelor’s degree in Chemistry, Analytical Chemistry, Materials Science, or related field (advanced degree preferred)
7+ years of experience in trace metals analysis, preferably in high-purity or semiconductor environments
Deep expertise in ICP-MS (required) and ICP-OES (required) operation and troubleshooting
Strong experience working at ultra-trace detection levels (ppt–ppb)
Hands-on experience in cleanroom or contamination-controlled laboratory environments
Preferred Qualifications
Experience supporting semiconductor materials (precursors, acids, solvents, cleans)
Familiarity with interference mitigation techniques (collision/reaction cell, spectral correction, matrix effects)
Experience with clean chemistry techniques (acid purification, low-metal labware practices)
Familiarity with SEMI standards and semiconductor customer purity expectations
Experience with LIMS and SPC tools for production data management
