About the Job

Requirements

  • An undergraduate degree in electrical engineering, mechanical engineering, or equivalent is required.
  • At least 5 years of experience in regulatory and compliance certification for solar, wind, battery, or other power electronics products is required.
  • Working knowledge of standards such as UL 1741, IEEE 1547, IEEE 2800, IEC 62477-1, UL 347, or similar standards is required.
  • Experience with high-voltage test equipment, including hipot, partial discharge systems, and impulse generators, as well as power analyzers, oscilloscopes, and data acquisition systems, is required.
  • Experience working with Nationally Recognized Testing Laboratories such as UL, CSA, TÜV, or Intertek on certification projects is required.
  • Technical writing and documentation skills are required.
  • The candidate must be able to identify creative solutions to difficult problems using first-principles engineering in ambiguous situations.
  • The candidate must remain engaged and proactive under pressure, own assignments, and take accountability.
  • Effective communication and negotiation skills and attention to detail are required.
  • Hands-on experience designing and operating test equipment and data acquisition systems, including oscilloscopes, power and spectrum analyzers, and data loggers, is required.

Responsibilities

  • Interpret UL, IEC, ISO, and other regulatory requirements and translate them into test plans, procedures, and pass/fail criteria supporting product certification and entry into new markets.
  • Plan and conduct safety, performance, and environmental compliance testing, including dielectric withstand, partial discharge, impulse, insulation resistance, temperature rise, abnormal and fault testing, and grid-interconnection testing.
  • Run in-house pre-compliance testing to identify design issues early and reduce formal certification risk.
  • Coordinate and support witness testing, TPTDP, and CTDP programs with Nationally Recognized Testing Laboratories and third-party labs, serving as Heron's technical point of contact during test campaigns.
  • Write traceable test reports, data packages, and certification evidence that meet Nationally Recognized Testing Laboratory and ISO/IEC 17025 expectations.
  • Design, build, and validate test setups, fixtures, and automation for medium- and high-voltage power electronics.
  • Analyze test failures with design engineering and drive root-cause analysis and corrective action.

Desired Qualifications

  • Experience designing or testing medium-voltage systems, such as 5 kV–35 kV systems, including insulation coordination, clearance and creepage, and partial discharge considerations.
  • Experience with manufacturing processes and material selection for high-power assemblies, such as busbars, potting, conformal coating, and high-voltage connectors.
  • Experience developing design failure mode and effects analysis, process failure mode and effects analysis, and hazard analysis and risk assessment for complex hardware design and manufacturing environments.
  • Experience participating in product-relevant standards committees.
  • Hands-on experience with test automation using Python, LabVIEW, or embedded scripting for power hardware validation.

About the Company

Heron Power

Develops solid-state transformers for grid modernization

Heron Power designs power-electronics-based solutions to modernize the electrical grid, emphasizing solid-state transformer technology. Its flagship Heron Link is a modular, megawatt-scale converter that connects directly to medium voltage and uses wide-bandgap semiconductors to regulate voltage and frequency while coordinating multiple energy sources through software. Compared with traditional transformers and early SS-T solutions, it offers higher power density, easier maintenance, and tighter grid stability through software-enabled control. Its goal is to enable a scalable, reliable, all-electric grid for renewables, storage, and data centers, with internal pilots in 2026 and U.S. manufacturing planned.
