Geochemist - Senior Level (Hybrid)

The role - what you'll do Barr is seeking a senior-level geochemist to join our growing geochemical practice across the Midwest and western United States as well as western Canada. This role can be based in any of our current offices on a part-time or full-time basis. In this role, you will lead and support projects involving tailings and mine waste, coal combustion residuals (CCR), legacy contamination, and other complex, multimedia environments. This role combines advanced geochemical modeling and material characterization expertise with project leadership and client engagement. You will provide technical direction on conceptual site models and assessment of geochemical systems, oversee data collection and analysis, lead predictive modeling efforts, and contribute to strategic decision-making related to acid rock drainage, metal leaching, mineral solubility, and water quality. In addition to technical leadership, this position includes mentoring staff, collaborating with clients and regulators, and supporting the continued growth of Barr's geochemical practice. This role also includes a strong client service and business development component, including relationship development, proposal support, and identifying new project opportunities. This role offers the opportunity to shape the direction of Barr's geochemical services and contribute to high-visibility projects across North America. The ideal candidate for this position is a strategic and collaborative consultant who combines deep technical expertise with strong leadership and client presence. They communicate complex geochemical concepts and modeling results clearly and confidently to clients, regulators, and multidisciplinary teams.
