About the Role

The Senior Process Development Engineer will support the development and commercialization of Cyclic’s Hub and Spoke process technologies, bridging R&D, process technology, pilot work, and process engineering. This role is crucial for building process understanding, organizing technical data, supporting process design, and enhancing knowledge capture and application across projects.

Responsibilities

• Lead the development of new process technologies from laboratory through pilot and commercial implementation.
• Develop a deep understanding of core unit operations using first-principles engineering, thermodynamics, reaction engineering, process modelling, and experimental data.
• Identify technology gaps, technical risks, and opportunities for process innovation.
• Design, support, and interpret laboratory and pilot test programs.
• Analyze laboratory, pilot, and operating plant data to support process development and engineering decisions.
• Translate laboratory and pilot testwork into commercial process designs.
• Develop scale-up strategies and evaluate scale-up risks.
• Participate in commissioning, startup, process validation, and performance testing of pilot and commercial facilities.
• Support process optimization during early commercial operation.
• Support technology transfer to Engineering, Operations, and Capital Projects.
• Develop process models, mass and energy balances, design basis documents, and other technical documentation to support technology development and commercialization.

Requirements

• Bachelor's degree in Chemical Engineering, Metallurgy, Mineral Processing, or related discipline.
• 4–8 years of experience in process development, hydrometallurgy, mineral processing, process engineering, or commercialization of new technologies.
• Strong background in hydrometallurgical process development and scale-up.
• Demonstrated experience leading metallurgical testwork and pilot plant programs.
• Experience supporting pilot plant operations, commissioning, startup, or commercial plant performance validation.
• Extensive experience developing commercial process designs from laboratory and pilot data.
• Strong understanding of chemical engineering fundamentals, reaction engineering, thermodynamics, mass transfer, transport phenomena, and process modelling.
• Experience developing Process Design Criteria and other core process engineering deliverables.
• Experience with process simulation software such as SysCAD, Aspen Plus, METSIM, IDEAS, or equivalent.
• Strong analytical and problem-solving skills.
• Excellent written and verbal communication skills.
• Demonstrated ability to lead multidisciplinary technical teams and mentor junior engineers.
• Experience with metallurgical testwork, pilot plant operations, or process development programs.
• Exposure to hydrometallurgical or mineral processing unit operations.
• Experience with SysCAD or similar process modelling tools.
• Experience with rare earths or other critical materials is an asset.
• Professional Engineer (P.Eng.) designation or eligibility in Ontario.
• Passionate about developing new technologies and bringing them to commercial reality.
• Comfortable leading ambiguous technical problems through structured engineering analysis.
• Naturally curious and driven to understand processes from first principles.
• Collaborative and able to influence across R&D, Engineering, Operations, and Project teams.
• Organized and committed to building lasting technical knowledge within the organization.
• Motivated by mentoring others and raising technical capability across the team.
