This includes producing detailed and study drawings for reinforced concrete, structural steel, fire plans, roadways, and grading, preparing bills of material, and participating in plant walkdowns to support configuration management.

KEY ACCOUNTABILITIES

• Develop and update civil drawings, sketches, and operational flowsheets for station projects/modifications.

QUALIFICATIONS

• Diploma in civil engineering technology.

• 4+ years of demonstrated experience producing and revising civil CAD deliverables (drawings, sketches, and operational flowsheets) for industrial/station facility projects.

• Proven capability developing detailed drawings for reinforced concrete, structural steel, fire protection/site plans, roadways, and grading.

• Experience participating in plant/field walkdowns, verifying as-built conditions, and incorporating field data into controlled design documents (configuration management mindset).

• Ability to gather, validate, and apply reference information from records, standards, and stakeholders; strong skill in confirming scope, requirements, and drawing limits before execution.

• Competence performing required civil/structural calculations using algebra, geometry, trigonometry, and prescribed formulas to support design accuracy.

• Strong communication and teamwork skills to resolve drafting/design questions, escalate conflicts/missing details, and coordinate inputs across multiple disciplines.

• Experience preparing BOMs/material lists (descriptions, catalog numbers, quantities) to support procurement, fabrication, and complete drawing documentation; familiarity with catalog-based material identification and asset/procurement systems (e.g., Passport or similar) preferred.

• Ability to produce mechanical engineering design deliverables using CAD tools.

OPG may use artificial intelligence (AI) tools as part of the applicant screening process. However, applications will also be reviewed by a member of our Recruitment team to ensure a fair and thorough assessment.

The base salary range considers many factors including, but not limited to experience, education, and training, including any collective agreement requirements for union represented positions. It is not typical for the salary to be offered near the top of the range, and salary is dependent on numerous factors. For management roles, the base salary range does not represent the total compensation package. The total compensation package for regular full-time management roles includes pay-for-performance programs for annual and medium time periods. Maintaining a high-performance culture and excellence is a core expectation of every member of our leadership team and is rewarded through the established compensation framework.

OPG is committed to employment equity. As such, we encourage applicants from equity-seeking communities (Indigenous Peoples, racialized persons, persons with disabilities, and women). We strongly believe that alleviating the under-representation of equity-seeking individuals will create a stronger OPG team and allow us to better serve the needs of our diverse communities.

In order to fulfill the above-mentioned purpose, priority in hiring may be given to qualified persons who self-identify as a member of equity-seeking groups as identified in the application process. This initiative constitutes a special program under the Human Rights Code/Canadian Human Rights Act.
