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.
