Hybrid Site Supervisor bei GEM Technologies, Inc.

ABOUT THE ROLE

We are seeking a Site Supervisor to join our team supporting the Lawrence Livermore National Laboratory! This position is full-time and will be based out of Livermore, California.

The Site Supervisor is a hands-on field leader responsible for planning, coordinating, and supervising all field activities associated with characterization, remediation, and decontamination & decommissioning (D&D) of radiologically- and beryllium-impacted facilities at an active DOE site. This role ensures safe, compliant, and cost-effective execution of work by leading field crews, implementing industrial hygiene and radiological controls, maintaining schedule and earned value reporting, and communicating with engineering, environmental, safety, and client stakeholders.

Responsibilities

• Lead and supervise multi-disciplinary field crews (craft, technicians, industrial hygienists, radiological control technicians) during characterization, remediation, and D&D activities in facilities with potential beryllium and radiological contamination.

• Provide daily direction, task assignments, and performance feedback.

• Develop, implement, and enforce site-specific work plans, safe work permits, Job Hazard Analyses (JHAs), and work control packages in coordination with safety and radiological personnel.

• Oversee and participate in all phases of sampling and characterization (surface sampling, swipe samples, air sampling, smear surveys, radiological surveys) for facilities up to Category 3 nuclear complexity; ensure samples are collected, labeled, and documented to chain-of-custody standards.

• Direct abatement activities under beryllium and asbestos programs: ensure proper containment, negative-pressure ventilation setups, decontamination lines, waste segregation, and packaged waste manifesting in accordance with site procedures.

• Coordinate pre-task briefings and daily tailboards; enforce PPE, respiratory protection, and decontamination requirements. Monitor worker exposures and work area controls in real time and act on deviations immediately.

• Serve as the field point of contact for safety/radiological incidents and near-miss investigations; support corrective action implementation and lessons-learned dissemination.

• Maintain accurate field documentation: daily logs, sampling records, survey maps, waste tracking, equipment logs, and photographic records for project and regulatory needs.

• Support project controls and program management by providing timely inputs to schedule, cost, and earned value management (EVM) systems; report progress, variances, and resource needs to project management.

• Communicate effectively across organizational levels — from craft personnel to site operations, regulatory representatives, prime contractor management, and DOE/client points of contact — ensuring transparency and alignment.

• Mentor and develop junior supervisors and crew leads; promote a culture of safety, quality, and continuous improvement.

Requirements

• Education & Years of Experience – Bachelor’s Degree and 10+ years of field experience leading crews in characterization, remediation, and D&D activities at active DOE or equivalent nuclear/radiological facilities, with documented experience in environments potentially impacted by beryllium and radiological contaminants.

• Citizenship – To be considered, you must be a United States (U.S.) citizen due to the federal nature of the work.

• Clearance – To be considered, you must be able to obtain and maintain a government issued clearance, if needed.

• Prior experience as a site superintendent, field superintendent, or equivalent role supervising on-site workers and implementing beryllium and asbestos abatement controls.

• Demonstrated experience performing and overseeing all phases of environmental and radiological sampling and characterization, including planning sampling strategies, supervising sample collection, and ensuring defensible chain-of-custody and laboratory submittals for facilities of up to Category 3 nuclear complexity.

• Strong written and verbal communication skills; proven ability to brief technical and non-technical audiences, prepare field reports, and coordinate with multiple client organizations.

Desired Skills

• Certifications: 40-hour HAZWOPER and annual refreshers, Respiratory Protection Program certification, Competent Person certifications relevant to demolition/abatement, or similar.

• Working knowledge of earned value management (EVM) concepts and tools (MS Project, Primavera P6, Deltek Cobra or other EVM tools) and experience providing accurate field inputs for schedule and cost performance reporting.

• Strong leadership qualities, conflict resolution skills, and a track record of developing crew performance and morale.
