We are looking for a Senior Engineer with a strong background in electrical and insulation design for medium voltage systems.
What You Will Do
- Design medium voltage insulation systems that minimize electric field concentrations, surface tracking, and dielectric stress leading to partial discharge
- Model and simulate electrostatic behavior using tools such as COMSOL, Ansys Maxwell, or similar finite element analysis platforms to predict PD inception voltage, creepage/clearance performance.
- Conduct partial discharge testing (offline, online, and type test formats) and interpret PD patterns to diagnose insulation defects, voids, or contamination
- Specify materials and insulation technologies (epoxies, polymers, ceramics, laminates, coatings) based on dielectric strength, aging characteristics, and environmental exposure
- Lead failure mode investigations for electrostatic breakdown, insulation degradation, corona discharge, and arc flash events, providing corrective design actions
- Collaborate with cross functional teams (mechanical, power electronics, safety, manufacturing) to integrate electrostatic protection into full product lifecycle
- Develop documentation and design guidelines for PDfree operation, grounding, shielding, and insulation coordination.
- Ensure compliance with relevant standards (IEC 60270, IEC 60664, IEEE 1584, NFPA 70/70E, UL standards, and internal safety requirements)
- BS/MS/PhD Electrical Engineering, Mechanical Engineering, Mechatronics, or closely related discipline
- Job title and position level will be determined based on the candidate’s experience
- Minimum experience: BS and 5 years / MS and 3 years / PhD with electronics design experience for a Senior Engineer
- Strong understanding of electrostatics, dielectric physics, insulation coordination, and medium voltage engineering
- Hands on experience with partial discharge measurement, PD inception/propagation mechanisms, and corona mitigation
- Experience with FEM electrostatic simulation tools (COMSOL, Ansys, CST, or equivalent)
- Knowledge of creepage/clearance design, insulation aging, and high voltage material selection
- Familiarity with industry standards governing PD, arc flash, and high voltage safety
- Proficiency with multi-physics modeling
- Medium voltage >5kV insulation
- Familiarity with common standards for electrical equipment and energy storage systems
