Job description

In this role, we are seeking a Senior Substation Designer to support the physical layout and design of medium to high voltage substation projects (15kV-500kV). You will be responsible for producing high-quality physical and electrical substation design packages and collaborating with multidisciplinary teams across engineering, project management, and construction.

This position is ideal for a highly skilled and proactive designer who enjoys both independent design work and team collaboration. You'll take the lead on design efforts from concept through construction and play a key role in mentoring junior designers.

Your Responsibilities will Include:

• Create complete physical design packages for new substations and retrofit projects including:
  • Substation general arrangements and equipment layouts
  • Elevations and section views
  • Grounding and lightning protection plans
  • Conduit, cable trench, and raceway plans
  • Foundation layouts and steel structure detailing
  • Control building layouts, cable tray, lighting, and grounding
  • Substation site plans and detailed bill of materials
• Coordinate with engineers and drafters to ensure designs meet project requirements and industry standards.
• Interpret one-line and three-line diagrams to develop complete physical drawings.
• Apply applicable codes and standards (IEEE, NESC, NEC, client-specific guidelines) to all design work.
• Incorporate vendor equipment drawings and specifications into design packages.

Design Support & Collaboration

• Collaborate with electrical and civil engineers, protection & control teams, and project managers to meet project milestones.
• Attend project kickoff meetings, design reviews, and client interface discussions.
• Provide field support and perform site visits to verify design accuracy and resolve issues during construction.
• Conduct quality checks and peer reviews of design work for accuracy and consistency.

Leadership & Mentorship

• Mentor and support junior designers and drafters.
• Provide design oversight on multiple projects and manage design deliverables.
• Support proposal efforts with design estimates, scopes of work, and schedule input.

Education & Years of Experience:

• 5+ years of substation physical design experience (preferably in utility or EPC environments).
• Associate degree in Drafting, Engineering Technology, or related field; equivalent work experience considered.

To Thrive in This Role, You Will Need:

• Proficient in AutoCAD, with strong drafting and layout skills.
• Understanding of substation equipment (transformers, breakers, switches, buswork, etc.).
• Familiarity with industry codes and standards including IEEE, NESC, NEC, ANSI, and client-specific requirements.
• Ability to read and interpret electrical drawings including one-line diagrams and schematics.
• Strong communication and organizational skills.
• Ability to work independently and as part of a multidisciplinary team.
• 8-10+ years of substation physical design experience.
• Proficiency with MicroStation, AutoCAD Electrical, or Substation Design Suite (SDS).
• Experience with Civil 3D, Inventor, or Revit for 3D modeling and visualization.
• Experience supporting physical design for control buildings (indoor panel layout, AC/DC load centers, cable tray, etc.).
• Familiarity with power system calculations like grounding studies, conductor sizing, or voltage drop analysis is a plus.

Environmental Factors and/or Physical Requirements:

While performing the duties of this job, this position is required to have ordinary ambulatory skills sufficient to visit other locations; and the ability to stand, walk, stoop, kneel, crouch, and manipulate (lift, carry, move) light to medium weights of 10-50 pounds. Requires good hand-eye coordination, and arm, hand and finger dexterity, including the ability to grasp, and visual acuity to use a keyboard, operate equipment and read application/form information. The associate frequently is required to sit, reach with hands and arms, talk, and hear.
