If you thrive on solving complex design challenges, enjoy collaborating across teams, and want to grow your technical skills in a fast-moving, high-impact industry, this is your opportunity to shine.

What You'll Do

You'll be a key contributor throughout the design and delivery lifecycle, including:

• Compile and analyze field data, surveys, sketches, diagrams, GIS, subsurface utilities, and technical inputs to support design development and planning.
• Develop engineering drawings, models, and layouts of piping systems based on existing conditions, design criteria, schematics, and engineering guidance.
• Produce accurate construction drawing packages, including plans, sections, elevations, isometric layouts, model-based reports, schedules, and redline revisions.
• Assist in developing and maintaining design and modeling standards that support quality, innovation, safety, and constructability.
• Partner with engineers and project managers to deliver reliable, high-quality designs that meet scope, budget, schedule, and client expectations.
• Apply engineering and design principles to evaluate proposals, technical requirements, and design solutions.
• Support technical staff with constructability reviews, risk identification, field assessments, remediation planning, and design improvements.
• Maintain organized, accurate site record drawings and documentation for assigned projects.
• Complete required training and continuously build professional capability in design tools, modeling platforms, and Oil & Gas industry practices.
• Uphold KLJ's Code of Conduct, demonstrating ethical decision-making, responsible use of resources, and a commitment to safety and quality.
