Field Technician – Senior Level (Hybrid)

The role – what you’ll do

Barr is seeking a part-time environmental field technician to join our Jefferson City office and work 8–12 hours per week at a client facility in the Bixby, Missouri, area and potentially other client facilities in southeastern Missouri. In this role, you will support the Assessment and Remediation business unit and undertake challenging and progressive work on projects related to the investigation, evaluation, and remediation of contaminated sites. The person in this position will perform routine operations and maintenance for a closed mine tailings site. Work will include completing site inspections, monthly well gauging activities, documenting site conditions through field notes and summary reports, and coordinating with contractors, other consulting firms, the Barr project manager, and the client project manager. Work may also involve overseeing contractors and documenting construction work. In addition, work may also include collecting groundwater, surface water, or soil samples.

The ideal candidate for this role is a clear and confident communicator who works effectively both collaboratively and independently. They are adaptable, organized, and proactive, bringing strong professional judgment and a high level of attention to detail to dynamic field and office environments. They take ownership of their work, anticipate needs, and contribute thoughtfully to project planning and execution. They demonstrate reliability, safety awareness, and a commitment to continuous improvement. Above all, they value teamwork, quality, and integrity in delivering impactful environmental solutions.

Your impact – key responsibilities

• Technical knowledge: apply foundational environmental principles to plan and carry out site investigations; collect and document high-quality soil, groundwater, and surface water samples; operate and calibrate field instruments; and follow SOPs, QA/QC protocols, and health-and-safety plans.
