Job Title:Senior Chemist, Technical Laboratory Operations
Job Description:The RoleEntegris 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
