Process Mechanical Engineer, Senior

What you will be doing in the role of Process Mechanical Engineer, Senior: 

Hydrogen Process Design & Safety

• Lead the process design of hydrogen production, electrolysis, compression, storage, refueling, venting, and distribution systems.

• Develop process design packages including:

• Process Flow Diagrams (PFDs)
• Piping & Instrumentation Diagrams (P&IDs)
• Process Descriptions
• Design Basis
• Operating Philosophies
• Control Narratives

• Develop and review:

• Cause & Effect Matrices
• Logic Diagrams
• Shutdown Philosophies
• Process Safety Requirements Specifications
• Functional Descriptions

• Establish startup, shutdown, purge, venting, and abnormal operating strategies for hydrogen systems.

• Define process control strategies and work closely with controls and automation teams to implement them.

• Participate in commissioning, startup, troubleshooting, and performance validation activities.

Process Safety & Risk Management

• Participate in HAZOP, LOPA, and other process hazard reviews.
• Develop and review safety shutdown strategies and risk mitigation measures.
• Ensure hydrogen systems are designed in accordance with recognized process safety principles and industry best practices.

Regulatory Compliance & Engineering Governance

• Serve as the technical lead for hydrogen-specific code and regulatory compliance.
• Develop compliance strategies and support regulatory approvals, submissions, and variance requests.
• Interface directly with regulatory authorities, customers, consultants, and equipment vendors.
• Ensure designs meet applicable requirements including:

• • CAN/BNQ 1784-000/2022
  • Ontario Regulation 214/01
  • TSSA High Pressure Piping Requirements
  • ASME B31.3
  • Applicable CSA, NFPA, and pressure equipment standards
• Maintain awareness of emerging hydrogen regulations, standards, and industry practices.

Customer & Technical Leadership

• Act as a trusted technical advisor to customers throughout project development and execution.
• Support business development activities through technical consultation, proposal reviews, and customer presentations.
• Collaborate with equipment vendors and technology providers to evaluate hydrogen solutions.
• Review and approve engineering deliverables prepared by other engineers.

Mentorship & Continuous Improvement

• Mentor and support the development of junior and intermediate engineers.
• Share knowledge and establish engineering standards for hydrogen system design.
• Support continuous improvement initiatives related to engineering quality, design tools, and project execution.

Knowledge and skills required for the role: 

• Bachelor's degree in Chemical Engineering, Mechanical Engineering, or a related discipline.
• Professional Engineer (P.Eng.) designation in good standing.
• 10+ years of experience in process engineering, industrial gas systems, chemical processing, fuel systems, hydrogen systems, or related industries.
• Demonstrated experience developing and reviewing:
• Strong understanding of process safety management principles and risk assessment methodologies.
• Experience leading multidisciplinary engineering projects from concept through commissioning.
• Excellent communication, problem-solving, and customer-facing skills.
• Candidates must demonstrate direct experience applying Canadian hydrogen and industrial piping regulations, including those outlined above. Experience applying these requirements to hydrogen production, compression, storage, fueling, venting, or industrial gas systems is considered essential for this role.

Preferred Qualifications

• Experience with hydrogen electrolysis systems.
• Experience with hydrogen compression, storage, dispensing, or refueling systems.
• Experience performing or facilitating HAZOP and LOPA studies.
• Familiarity with SIL assessments and functional safety principles.
• Experience supporting startup and commissioning of industrial process systems.
