About the Job

Requirements

  • A Bachelor of Science or Master of Science in Electrical Engineering, Computer Engineering, or a related field is required; an advanced degree is a plus.
  • At least 10 years of engineering experience in test engineering, validation, or power electronics hardware development, including at least 4 years in a people-leadership role managing technical teams.
  • A strong hands-on background in test engineering for power electronics, including high-voltage, high-power conversion systems.
  • A solid understanding of PCBA schematics and hardware debugging, and experience using oscilloscopes, multimeters, power analyzers, and other lab instrumentation.
  • A proven track record leading the design, build, and deployment of manufacturing test systems and product validation programs, ideally from prototype through volume production.
  • Demonstrated success running and scaling a test lab, including managing uptime, calibration, safety, and capacity.
  • The ability to collaborate with partners in electrical engineering design, mechanical engineering design, firmware, manufacturing, and program management.
  • A track record of hiring, developing, and retaining strong technical talent, with the ability to provide credible technical guidance to senior and staff engineers.
  • The ability to drive action grounded in first-principles thinking and take entrepreneurial ownership in a high-growth environment.
  • Willingness to travel up to 10%, including internationally.

Responsibilities

  • Lead, mentor, and grow a team of test engineers responsible for manufacturing test and product validation of high-voltage power electronics products.
  • Provide technical guidance and set direction on test architecture, methodology, and execution while empowering engineers to own their domains.
  • Own the end-to-end strategy and execution for manufacturing test and product validation, including test coverage, accuracy, cycle time, cost, and scalability for volume production.
  • Oversee the design, build, validation, and deployment of test systems for high-voltage, high-current power electronics, ensuring systems are delivered on time and meet performance targets.
  • Ensure high test system uptime across prototype labs, pre-production, and manufacturing environments; establish rapid response and root-cause resolution when testers fail, as well as preventive maintenance and reliability practices.
  • Own the test lab, including layout, equipment, calibration cadence, safety standards, capacity planning, and day-to-day operations.
  • Define manufacturing test specifications for volume production in partnership with operations, design, quality, and reliability teams.
  • Partner with the program management team to plan resources and align milestones, dependencies, and deliverables across the engineering organization.
  • Collaborate with electrical engineering design, mechanical engineering design, and firmware teams to influence design for testability, investigate failures, and drive product improvements from first principles.
  • Drive continuous improvement of test efficiency, coverage, and automation, including investments in tooling and automated test infrastructure that scale with volume.
  • Establish frameworks for test requirements decomposition, acceptance criteria, and program execution that scale with the company.

About the Company

Amperesand

Modular solid-state transformers for grid power

Amperesand develops modular solid-state transformers (SSTs) for grid infrastructure using silicon carbide (SiC) devices and proprietary high-frequency transformers. The SSTs are digitally controlled and bidirectional, offered in 2, 4, and 6 MW modules that can be combined to meet larger needs, replacing traditional transformers, switchgear, and UPS in a single AI-driven system. It differentiates itself through the combination of SiC SSTs, proprietary high-frequency transformers, digital power management, and leadership from NTU R&D spun out with Temasek’s Xora Innovation, plus an experienced team from ABB, GE, Siemens, and Vestas. The goal is to speed up the energy transition by delivering scalable, compact SST systems for EV charging networks, microgrids, data centers, and industrial power, with first deliveries planned for 2025 in the US and Singapore.
