We're looking for an experienced Lead Process Engineer to join our Toronto office, bringing strong technical expertise, leadership, and a collaborative approach to project delivery.

In this role, you'll lead process engineering activities across a diverse portfolio of projects, from early-stage studies (PEA, PFS and FS) and trade-off evaluations through to basic engineering, detailed design and execution-phase projects. You'll work closely with multidisciplinary teams and clients, providing technical direction, developing practical and innovative solutions, and helping deliver successful project outcomes.

About the role

• Lead process engineering activities across mining and mineral processing studies and projects, from early-stage studies (PEA, PFS and FS) through basic engineering, detailed design and project execution.
• Take ownership of process engineering scope, deliverables, schedules and budgets, ensuring designs are technically sound, fit for purpose, and meet project quality and safety requirements.
• Provide technical leadership and mentorship to process engineers, reviewing deliverables and guiding the team to deliver practical, innovative and cost-effective solutions.
• Act as a key point of contact for clients on process engineering matters, leading technical discussions, design reviews and presentations.
• Collaborate with Project Managers, Study Managers and multidisciplinary engineering teams to coordinate activities, resolve technical challenges and support successful project delivery.
• Lead the development and review of key process engineering deliverables, including design criteria, process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), mass and energy balances, and equipment specifications.
• Lead process evaluations, trade-off studies and process safety reviews, including HAZOP and LOPA, identifying technical risks and opportunities for improvement.
• Contribute to technical sections of regulatory and disclosure reports, including NI 43-101 and S-K 1300 reports, as applicable.
• Support proposal development, scope definition, engineering estimates and business development activities, including client presentations.
• Collaborate with Ausenco's global Process Engineering team to share knowledge, best practices and innovative approaches to mineral processing design.

About you

• Bachelor's degree in Mineral Processing, Extractive Metallurgy, Chemical Engineering or a related engineering discipline.
• Minimum 12 years of relevant experience in mineral processing engineering, including front-end studies, basic engineering and detailed design.
• Professional Engineer (P.Eng.) designation in Ontario, or registration in another Canadian province with the ability to obtain Ontario licensure.
• Demonstrated experience leading process engineering teams and deliverables on multidisciplinary mining projects, ideally within an engineering consulting environment.
• Strong technical expertise in one or more of the following: comminution, flotation, pyrometallurgy, hydrometallurgy, ion exchange (IX), solvent extraction (SX), and solid-liquid separation or filtration.
• Experience across a range of mineral commodities, including critical minerals, precious metals, base metals and battery metals.
• Strong technical judgment, critical thinking and problem-solving skills, with the ability to evaluate alternatives, challenge assumptions and develop practical engineering solutions.
• Excellent communication and interpersonal skills, with proven ability to lead client discussions, present technical recommendations and collaborate with multidisciplinary teams.
