The Role

Ready to take your substation design expertise to the next level? As a Senior Substation Designer, you'll play a key role in shaping the design of electrical substation projects, bringing complex engineering concepts to life through thoughtful, high-quality design solutions. From leading design efforts and developing detailed construction packages to collaborating with engineers and guiding fellow designers, you'll have the opportunity to make a lasting impact on projects that support the infrastructure communities rely on every day.

In this role, you'll bring your technical expertise and problem-solving skills to a variety of challenging projects while helping drive design quality, consistency, and project success. You'll serve as a trusted technical resource, contribute to project planning and execution, and help develop the next generation of design talent. If you're passionate about your craft, enjoy tackling complex challenges, and want to be part of a collaborative team where your experience and ideas make a difference, we'd love to meet you.

What Your Day Will Look Like

• Lead the development of detailed engineering drawings and design packages for new, modified, and existing substations using AutoCAD.
• Provide design support across the Substation Engineering department, including physical, electrical, and protection and control projects.
• Develop and review one-lines, schematics, wiring diagrams, general arrangements, plans and sections, grounding, foundations, conduit and cable plans, equipment layouts, and detailed construction drawings.
• Translate complex engineering requirements, calculations, specifications, and markups into complete construction-ready design packages.
• Develop and review bills of material, conduit and cable schedules, equipment documentation, and other technical project deliverables.
• Support the design and modification of transformers, circuit breakers, switches, control houses, bus systems, grounding systems, raceways, cabling, and other substation equipment and infrastructure.
• Coordinate drawing packages across engineering disciplines and identify design, constructability, and drawing conflicts.
• Apply client standards and applicable NEC, NESC, IEEE, NEMA, and ANSI requirements to design work.
• Perform field reviews and ensure field conditions and markups are accurately incorporated into final and as-built drawings.
• Perform quality control reviews of drawings and design packages for accuracy, consistency, and completeness.
• Work closely with engineers, project managers, and other designers to support project schedules and deliverables.
• Provide technical guidance, drawing support, and mentorship to entry-level and mid-level designers.
• Assist with resolving design issues during construction, testing, and commissioning.
• Manage multiple design assignments and priorities while meeting project schedules and client requirements.
• Travel to project sites as needed, up to approximately 25%.
• Perform other duties as assigned.

What You'll Bring to the Familia

Essentials to Succeed:
