Core Responsibilities

Primary Functions

Perform complex chemical analysis of environmental samples, including water, soil, air, and hazardous waste, for a wide range of organic and inorganic contaminants.
Operate, maintain, calibrate, and troubleshoot sophisticated analytical instrumentation such as Gas Chromatography (GC), Gas Chromatography-Mass Spectrometry (GC/MS), Liquid Chromatography (LC/MS), and Inductively Coupled Plasma (ICP-MS/OES).
Adhere strictly to established EPA, NELAC, TNI, and other state/federal regulatory methods (e.g., SW-846, 500/600 series) during all analytical procedures.
Execute and document rigorous Quality Assurance/Quality Control (QA/QC) protocols, including the analysis of method blanks, laboratory control samples, matrix spikes, and duplicates to ensure data validity.
Meticulously prepare samples for analysis using a variety of wet chemistry and extraction techniques, such as solid-phase extraction (SPE), acid digestion, and solvent extraction.
Review, interpret, and validate analytical data with a high degree of accuracy, identifying and investigating any anomalies, deviations, or out-of-control trends.
Prepare, assemble, and review comprehensive data packages and analytical reports for submission to clients, project managers, and regulatory agencies.
Utilize a Laboratory Information Management System (LIMS) for sample log-in, tracking, data entry, results processing, and final report generation.
Maintain clear, detailed, and defensible documentation of all laboratory activities, from sample receipt to final data reporting, in laboratory notebooks and electronic systems.
Author, review, and revise Standard Operating Procedures (SOPs) for analytical methods, instrument operation, and laboratory safety protocols.
Develop, validate, and implement new analytical methods to meet evolving client needs, regulatory requirements, or to analyze for emerging contaminants.
Manage the inventory of chemical standards, reagents, and laboratory consumables to ensure uninterrupted workflow and operational readiness.
Uphold and promote a strong safety culture within the laboratory, ensuring proper handling, storage, and disposal of hazardous chemicals and waste in accordance with safety guidelines.
Investigate and document non-conformance events or quality issues, implementing effective Corrective and Preventive Actions (CAPAs) to prevent recurrence.
Provide technical guidance, training, and mentorship to junior chemists and laboratory technicians on analytical techniques and procedures.
Participate actively in internal and external proficiency testing programs to maintain laboratory certifications and demonstrate analytical competency.
Interface with project managers and client service teams to clarify project requirements, analytical scopes, and turnaround time expectations.
Perform routine instrument maintenance and performance checks to minimize downtime and ensure optimal analytical performance.
Analyze high-resolution mass spectrometry data for the identification and quantification of unknown compounds and trace-level contaminants.
Assist during internal and external laboratory audits by providing documentation, explaining procedures, and addressing inquiries from auditors.
Communicate complex analytical results and their scientific implications effectively to both technical and non-technical stakeholders.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
