Senior Engineer, Model Validation

Job Overview
Reporting to the Manager, Project Engineering, JSG’s client is seeking a Senior Engineer, Model Validation to review and validate power system models and Project Data Update Packages (PDUPs).

In this role, you will serve as a subject matter expert and key resource for model validation activities. You will also provide coaching and mentorship through internal training, the development of guidelines and checklists, and the improvement and streamlining of internal processes.

You will be accountable for PDUP validation processes to help ensure the accuracy and consistency of models submitted for interconnection studies. You will play a critical role in strengthening technical capabilities in power system studies and supporting the timely, high-quality delivery of project deliverables.

You will work closely with Lead Engineers within the team, as well as Senior and Principal Engineers across JSG’s client, and collaborate with internal and external stakeholders on matters related to project modelling.

This full-time opportunity offers a competitive salary, paid vacation and flex time, health and dental benefits, mental health support, a defined contribution pension plan, and learning and development opportunities as part of the overall compensation package.

Must Haves:

• Bachelor of Science degree in Electrical Engineering.
• Registered as, or eligible to become, a Professional Engineer (P.Eng.) with APEGA.
• 10+ years of engineering experience in the electric utility industry, with a strong focus on power system modelling and analysis, including PDUP creation, review, and validation.
• Comprehensive understanding of Alberta’s electricity-sector regulatory framework, applicable tariffs, reliability standards, and transmission facilities.
• Proficiency with power system study tools, with strong knowledge of PSS®E-based steady-state and dynamic studies, as well as electromagnetic transient studies for interconnection purposes.

Nice to Haves:

• Experience developing and validating power system models for both Electromagnetic Transient (EMT) and phasor-domain simulations.
• Experience in transmission planning, power system operations, and customer access studies.

You Will Enjoy Working Here If You:

• Value flexibility to support personal and professional needs, while recognizing that some weeks may require additional onsite presence during key business or operational events.
• Enjoy working with a team of highly skilled professionals in a diverse environment with varied backgrounds, experiences, and perspectives.
• Thrive in a dynamic environment and seek opportunities to drive meaningful change.
• Use strong communication skills to collaborate effectively with internal and external stakeholders in a fast-paced environment.
• Have an aptitude for developing the competencies and technical skills of others.
• Enjoy coaching and mentoring engineers and technical professionals.
• Collaborate effectively with peers and management teams to provide technical expertise.
• Are comfortable working in a matrix environment and influencing outcomes with or without direct authority.
• Can help resolve conflicts in complex situations and navigate ambiguity to achieve high-quality outcomes.

Accountabilities Include, But Are Not Limited To:

• Lead independent technical reviews and validation of project models used in power system studies, including load flow, short-circuit, dynamic, and stability studies.
• Validate model logic, assumptions, data sources, methodologies, and results for accuracy, robustness, and suitability for their intended use.
• Review and validate generator, plant, and network static and dynamic models, including parameterization and control representations.
• Validate line impedances (R, X, B), thermal ratings, seasonal limits, transformer parameters including impedances, tap changers, phase shifters, and grounding, as well as substation configurations, breaker models, bus arrangements, and protection interfaces as required.
• Assess model convergence, numerical stability, and sensitivity to parameter variations.
• Interpret modelling results and clearly communicate implications, risks, sensitivities, and uncertainties to market participants and other stakeholders.
• Identify and mitigate model-related risks, escalating material issues that could impact project or system decisions to the appropriate internal and external teams.
• Establish and apply structured model validation frameworks, checklists, and peer-review protocols.
• Support the development and validation of interconnection study cases.
• Mentor engineers and reviewers on best practices for power system and transmission modelling.
• Participate in cross-functional technical groups and share best practices and technical information with the Project Engineering team.
