Hands-on authorship of detailed high-voltage substation designs at 69kV and above, including switchyard layouts, one-line diagrams, grounding and lightning protection, insulation coordination, protection philosophies, AC/DC auxiliary systems, and station service systems.
Experience delivering substation projects from concept through construction, commissioning, and energization, including field time.
Experience developing or reviewing technical specifications for major substation equipment, including transformers, breakers, AIS and GIS equipment, and protection systems, and supporting technical bid evaluations.
Ability to perform and review short circuit, load flow, grounding, insulation coordination, and equipment duty studies.
Working knowledge of ETAP, SKM, PSCAD, PSS/E, CDEGS, or similar tools.
Strong understanding of applicable Canadian codes and utility standards.
Ability to work effectively in a fast-paced, multi-project environment.
Ability to communicate with utilities, contractors, and internal stakeholders.
Attention to quality, safety, and reliability.
Ability to balance standardization with project-specific customization.
Willingness to travel regularly to Prince George and other IREN sites in British Columbia, and Alberta in the future.

Responsibilities

Lead and review detailed design of high- and medium-voltage substations, typically 12kV to 287kV, including one-line diagrams and protection philosophies, switchyard layouts, grounding and lightning protection systems, AC/DC auxiliary systems and station service design, cable routing, duct banks, and raceway design.
Act as Owner's Engineer, overseeing external engineering consultants and EPC contractors for substation design.
Review and approve engineering deliverables, calculations, drawings, and specifications.

P.Eng designation or eligibility for registration with EGBC.
Interconnection experience with a Canadian utility such as BC Hydro, ATCO, or Fortis.

Job Type: Full-Time | Location: British Columbia (Vancouver or Prince George, hybrid) with regular travel to IREN sites | Department: Engineering | Reporting to: VP, Engineering
IREN is a leading AI Cloud Service Provider, delivering large-scale GPU clusters for AI training and inference. IREN's vertically integrated platform is underpinned by its expansive portfolio of grid-connected land and data centers in renewable-rich regions across the U.S. and Canada.

Reporting to the Vice President of Engineering, the Senior High Voltage Design Engineer acts as Owner's Engineer for the design of the high and medium voltage substations that connect our Canadian data center campuses to the grid, typically 12kV to 287kV. You will direct and review the work of external engineering consultants and EPC contractors, partner with utilities such as BC Hydro, and set the standardized substation designs we will repeat across our greenfield and brownfield sites.

This is a design role for someone who has designed substations. You have produced switchyard layouts, grounding and lightning protection designs, protection philosophies and engineering studies yourself, at a consulting firm, an EPC or a utility, and carried them through construction and energization. That is what lets you hold a consultant's design to account. It is not a project management, distribution design or field technician role.

With 100% renewable energy, we build, own and operate our data centers and take pride in being at the forefront of sustainable solutions for the ever-evolving applications of high-performance compute. We believe that human progress is invaluable, but it should be done in the right way: responsibly, sustainably and having a positive impact on the communities we operate in.

Responsibilities

Lead and review the detailed design of HV/MV substations (typically 12kV to 287kV), including one-line diagrams and protection philosophies, switchyard layouts, grounding and lightning protection systems, AC/DC auxiliary systems and station service design, cable routing, duct banks and raceway design.
Act as Owner's Engineer, overseeing external engineering consultants and EPC contractors for substation design.

Ensure designs align with project requirements, reliability targets and internal standards.
Support value engineering and constructability reviews to optimize cost, schedule and scalability.
Provide engineering support during construction (RFI responses, site issue resolution), Factory Acceptance Tests (FAT), Site Acceptance Tests (SAT), commissioning and energization.
Conduct site visits to verify existing conditions and monitor installation quality.
Coordinate across disciplines including civil, structural, protection and control (P&C) and SCADA.
Collaborate with internal teams (data center design, construction, operations).
