Senior CEMS Field Service Tech — On-Site Expert

Sacramento region preferred | Northern California location flexibility $55-$65/hour base pay + paid overtime | Full-time, hourly/non-exempt Sign-on incentive and relocation assistance available for highly qualified candidates. If you are the person others call when a CEMS problem will not go away, we would like to meet you. Pacific Standard Environmental (PSE) is expanding its California Continuous Emissions Monitoring Systems (CEMS) service team. We are looking for an experienced technician who can independently solve difficult problems, take ownership of customer systems and help other technicians develop. CEMS field service, systems integration and environmental compliance support are central to our business. You will work closely with our service and engineering teams while taking ownership of complex field work. What you can expect

• Base pay of $55-$65/hour, based on relevant experience and demonstrated capability, plus regular opportunities for paid overtime.
• Customer-site travel paid portal-to-portal at the same hourly base rate as on-site work, with applicable overtime. Business mileage is reimbursed separately, in accordance with PSE policy.
• Three weeks of paid vacation annually and nine paid holidays, subject to PSE policies.
• Medical insurance with an employer contribution, plus dental, vision, a health savings account option and group term life insurance. PSE provides a 3% employer contribution to the 401(k) retirement plan regardless of employee contribution. Benefits are subject to plan terms and eligibility.
• PSE provides a laptop, company cell phone or phone allowance, tools/test equipment, PPE and uniforms.
• Technical autonomy, opportunities to mentor others and contribute to innovative training development, and potential growth into technical specialist, lead or regional service leadership roles as opportunities develop.

What you will do

• Independently troubleshoot and maintain complete CEMS, including analyzers, probes, heated lines, sample-conditioning systems, pumps and associated instrumentation.
• Diagnose electrical, electronic, pneumatic and communications problems; work with PLCs, Modbus and network interfaces; interpret drawings, P&IDs and technical manuals.
• Perform calibrations and quality-assurance checks; support CGAs, RATAs, converter-efficiency, response-time and sample-system bias testing.
• Support startups, commissioning, upgrades and repairs; identify components and recommend sound technical solutions.
• Communicate clearly with customers, document work accurately and mentor developing technicians while maintaining safe work practices.

What makes a strong candidate

• 10+ years of relevant CEMS, analyzer or instrumentation experience preferred, including substantial hands-on CEMS work. Exceptional candidates with 7-9 years who already perform at a senior level are encouraged to apply.
• Demonstrated ability to troubleshoot complete CEMS independently, with strong analyzer/sample-system and electrical/electronics skills.
• Practical knowledge of 40 CFR Parts 60 and/or 75, applicable air-district requirements, CEMS quality assurance, commissioning and audit support. SCAQMD experience is especially valuable for the Southern California role.
• Experience with Teledyne, Thermo Scientific, California Analytical Instruments (CAI), Siemens/ULTRAMAT, AMETEK or comparable equipment. You do not need experience with every manufacturer listed.
• Strong judgment, customer communication, documentation and mentoring skills; a valid driver's license, acceptable driving record and reliable transportation for customer-site work. Demonstrated technical capability matters more than a particular degree.

Schedule, travel and on-call coverage This is a hands-on, customer-site field position, not a remote desk job. Work is primarily regional and generally scheduled on weekdays, with regular overtime and occasional after-hours or weekend assignments. Plan for approximately eight nights away from home per month; travel varies with customer and project needs, and assignments may occasionally extend outside your usual territory. Technicians share on-call coverage, typically about one week every seven to eight weeks. Applicable overtime is paid; actual schedules and overtime hours vary. We value accountability, attention to detail, continuous growth and genuine care for customers and coworkers. We are developing more structured, innovative training and ways to share technical expertise across the team. An experienced technician can help shape that work while continuing to do meaningful hands-on service. You do not need to be actively job hunting to start a conversation. We welcome experienced professionals who are doing well where they are but would consider the right next step. Apply for priority consideration by October 14, 2026 We review applications as they arrive. Initial interviews are planned for the week of October 5th, with earlier conversations possible for particularly strong candidates. Hiring is rolling; a position may be filled before the priority date, and applications will continue to be considered while an opening remains available. Apply through this posting with your resume or a brief summary of your CEMS experience. No cover letter is required. Tell us which systems you know best, where you are based and whether relocation would be needed. Confidential inquiries are welcome. For highly qualified candidates, we welcome a conversation about the overall compensation package and what matters most in your next role. We will not contact your current employer without your permission. Sign-on and relocation arrangements depend on candidate eligibility and written offer terms. Career progression depends on demonstrated capability and available opportunities. Pacific Standard Environmental is an equal opportunity employer. Reasonable accommodations are available during the application process and for performing essential job functions. #J-18808-Ljbffr Pacific Standard Environmental, Inc.
