Your Opportunity

Stantec is seeking a Senior Environmental Scientist, Civil Engineer, or Geologist to join our growing Site Assessment and Remediation Team. The successful candidate will serve as a technical and project lead for CERCLA, legacy-mine, active-mine closure, and environmental remediation projects. Our team supports clients throughout the mining life cycle, from exploration and operations through closure and post-closure.

The position requires a detail-oriented and organized professional who can lead multidisciplinary teams; develop technical approaches, scopes, budgets, and schedules; perform and review site characterization and/or engineering analyses; prepare mine-closure and remediation documents; and produce clear, technically defensible reports.

The successful candidate will collaborate with clients, regulatory agencies, contractors, technical specialists, and Stantec staff across multiple offices. The position may require concurrent support of several projects.

Your Key Responsibilities

• Lead and support CERCLA remedial investigations and feasibility studies, engineering evaluations and cost analyses, remedial design, legacy-mine reclamation, and active-mine closure projects.

• Develop and evaluate remedial and closure alternatives for mine waste, tailings, waste rock, mine-impacted water, contaminated soil, and associated infrastructure.

• Lead site investigations and characterization programs, including development of technical approaches, work plans, sampling programs, conceptual site models, and data-gap evaluations.

• Collaborate with hydrogeologists, geologists, geochemists, environmental scientists, risk assessors, and geotechnical, civil, and mining engineers.

• Develop mine-closure plans, remedial designs, technical memoranda, investigation reports, feasibility studies, design reports, drawings, specifications, and cost estimates.

• Develop and manage project scopes, budgets, schedules, staffing plans, technical risks, and deliverables.

• Lead and support coordination with clients, federal and state regulatory agencies, consultants, contractors, subcontractors, and vendors. Attend and participate in regulatory meetings to support advancement of client goals.

• Lead project activities in accordance with Stantec, client, and site-specific health and safety requirements, including work at active and legacy mine sites and remote field locations.

• Conduct technical quality assurance and quality control reviews of project deliverables.

• Mentor junior and mid-level staff and support the development of multidisciplinary project teams.

• Support client-service management, proposal preparation, and other business-development activities.

Your Capabilities and Credentials

• Demonstrated experience supporting mine closure, mine reclamation, CERCLA remediation, contaminated-site assessment, or related environmental engineering projects.

• Strong knowledge of site characterization, remediation, mine-closure planning, remedial or closure design, and construction support.

• Experience working with federal and state environmental or mining regulatory agencies as the lead consulting representative.

• Strong knowledge of CERCLA and mine reclamation regulations.

• Ability to independently evaluate technical information, identify data gaps and project risks, and develop practical and technically defensible recommendations.

• Demonstrated ability to lead multidisciplinary teams and manage project scopes, budgets, schedules, and deliverables.

• Exceptional technical writing, verbal communication, organizational, analytical, and technical leadership skills.

• Demonstrated experience developing and maintaining positive client relationships.

• Demonstrated experience implementing and promoting a strong health and safety culture during field investigations, construction activities, and work at active or legacy mine sites.

• Experience preparing or implementing site-specific health and safety plans, conducting job hazard analyses, and leading safety briefings is preferred.

• Current 40-hour HAZWOPER training and annual refresher, or the ability to complete required training before beginning applicable field assignments, is preferred.

• MSHA Part 46 or Part 48 training is preferred.

• Ability to work independently and make sound decisions in office, field, construction, and remote-site environments.

• Ability to work collaboratively and inclusively with teams across multiple disciplines and office locations.

Education and Experience

• Bachelor’s degree in environmental science, civil engineering, geology, or a related engineering/science discipline. Master’s degree is preferred.

• Minimum of 10 years of relevant professional experience; 15 years is preferred.

• Professional Engineer/Geologist registration is preferred.

• Experience in the mining, environmental remediation, or industrial sectors is required.

• Preference will be given to candidates located in Denver, Salt Lake City, or Phoenix.
