Job description

Lead Technical Sales Engineer – Electrical Power Systems / Transformers

Lead Technical Sales Engineer – Electrical Power Systems / Transformers
Full-Time | Exempt | Reports to VP of Sales Operations

Build the Future of Critical Infrastructure

Join a rapidly growing organization at the forefront of power infrastructure solutions, supporting hyperscale data centers, renewable energy projects, and large industrial facilities. This is a high-impact, customer-facing role where you’ll combine deep technical expertise with strategic sales to deliver reliable, innovative transformer solutions.

If you thrive at the intersection of engineering and client engagement, and enjoy solving complex technical challenges—this is the opportunity to lead from the front.

What You’ll Do

Technical Sales & Application Engineering

• Serve as the lead technical expert on complex proposals and projects
• Review RFQs, specifications, and single-line diagrams to develop compliant, competitive solutions
• Recommend and design medium voltage transformer solutions (padmount, unit substation, dry-type)
• Partner with sales and customers to present solutions, resolve technical challenges, and win projects
• Support projects across data centers, renewable energy (solar/wind), and industrial sectors

Controls, Monitoring & Retrofit Solutions

• Translate field data and test results into actionable retrofit and upgrade scopes
• Advise on protection schemes, automation, and monitoring systems
• Lead integration of smart monitoring and control technologies

Internal Technical Leadership

• Mentor inside sales and operations teams on transformer applications and power systems
• Develop technical tools, guides, and training materials
• Act as a bridge between sales, engineering, and field teams

What We’re Looking For

• 10+ years of experience in sales engineering, application engineering, or power systems
• Strong expertise in medium voltage transformers (up to 35kV):
  • Padmount
  • Unit substation (liquid-filled)
  • Dry-type / cast resin
• Deep knowledge of IEEE, ANSI, and NEMA standards
• Familiarity with NETA testing standards and commissioning practices
• Ability to read and interpret:
  • Electrical drawings & single-line diagrams
  • Specifications & protection schemes
• Bachelor’s degree in Electrical Engineering (BSEE) or related field (PE a plus) (Equivalent hands‑on field experience also highly valued)
• Strong communication skills—comfortable in both field environments and executive presentations
• Willingness to travel up to ~10% (customer sites, project support, factory visits)

Why This Role Stands Out

• Work on high-visibility, mission-critical data center projects
• Blend technical expertise with strategic sales impact
• Collaborate with a highly experienced and supportive team
• Opportunity to shape solutions in fast-growing markets like data centers and renewable energy
• Competitive compensation + strong long‑term growth potential
