• Plan, oversee, and manage site investigation programs (leachate, groundwater, LFG) and field work.
• Prepare and support regulatory approvals for new infrastructure, expansions, amendments, and renewals.
• Evaluate and implement risk‑based solutions (risk management, remediation, closures) and ensure facility compliance.
• Provide senior technical review and professional authentication of reports, memos, and engineering documents.
• Prepare project scopes, cost estimates, schedules, and plans to deliver projects on time and on budget.
• Mentor and coach project teams and promote a culture of quality in project delivery.
• Maintain client and stakeholder relationships and participate in business development for the waste sector.
• Develop and implement project‑specific health & safety documentation, conduct site safety inspections, and ensure compliance.
• Conduct activities in line with internal procedures, legislation, and industry standards.

• Work in a safe manner at all times and report all health and safety incidents and concerns.
• Additional duties as required.
   

Qualifications:

• Bachelor’s degree in Science or Engineering (minimum); Master’s in a waste‑management‑related field preferred.
• 10–15 years progressive project execution and management experience; experience on medium–large projects (engineering fees > $500K). PMP is an asset.
• Registered P.Eng. or P.Geo. and membership in a Canadian engineering/geoscience association; ability to act as Qualified Professional in select jurisdictions preferred.
• Strong geoenvironmental expertise related to leachate, groundwater, landfill gas, soil vapour, and geochemistry.
• Extensive site‑investigation experience (drilling, geological classification, monitoring‑well installation, hydraulic testing, and ASTM sampling protocols); construction/remediation experience an asset.
• Proven ability to analyze complex geochemical and geospatial datasets and develop conceptual site models to support practical risk‑management and remediation solutions.
• Familiarity with technical software (e.g., Surfer, HELP, MODFLOW, AquiferTest) and database/statistical tools is an asset.
• Excellent technical writing, communication, leadership, and mentoring skills; strong attention to data quality and project delivery.
• Knowledge of provincial and federal codes, guidelines, and regulatory approval processes for waste facilities preferred.
• Valid provincial Class 5 driver’s license (or equivalent); strong safety leadership and completion of safety training are assets.
• Certifications or training from recognized solid‑waste organizations (e.g., SWANA, Compost Council of Canada) considered an asset.
