Staff PCB Designer, Power Electronics

San Francisco, California, United States

Company Overview   

Amperesand is disrupting industrial power with the first commercialized Solid State Transformer systems. Solid State Transformers systems are much more than a transformer replacement, enabling numerous advanced features to unlock solutions for data centers, EV charging, renewables, microgrids, and industrial installations. We are looking for mission driven team members passionate about making amazing products for worldwide electrification at maximum acceleration. Amperesand is building a global company and looking for talent across our geographies.  

Role Summary 
We are seeking an experienced PCB Designer to support the development of medium-voltage (MV) power electronics products. This role focuses on high-energy, high-voltage PCB layouts where clearance and creepage (C&C), insulation coordination, and safety compliance are critical.

The ideal candidate has deep hands-on experience designing MV/HV boards and understands the safety, manufacturability, and compliance requirements unique to power electronics. You will partner closely with power electronics engineers, manufacturing partners, and supply chain teams to deliver safe, reliable, and production-ready designs.

Responsibilities:

PCB Layout & MV Design Execution

  • Design and develop PCB layouts for MV power electronics systems, including high-voltage, high-current, and high-power-density applications

  • Apply and enforce clearance and creepage (C&C) requirements, including slotting, cutouts, coating considerations, and material selection

  • Implement insulation coordination strategies based on system voltage, pollution degree, overvoltage category, and applicable safety standards

  • Design with strong consideration for thermal performance, current density, electric field control, and partial discharge risk

  • Support multi-layer, heavy copper, and mixed-signal power/control board designs

Manufacturing Documentation & Production Release

  • Generate and release complete manufacturing packages, including Gerber files, drill files, stackups, fabrication notes, and assembly drawings

  • Define PCB fabrication constraints related to high-voltage spacing, materials, and tolerances

  • Collaborate with PCB fabricators and contract manufacturers during prototype and production builds

  • Resolve HV-related DFM issues and ensure smooth transition from design to manufacturing

BOM Management & Component Engineering

  • Create, maintain, and manage BOMs for MV power electronics assemblies

  • Verify component electrical ratings, insulation systems, packages, and PCB footprints

  • Identify, evaluate, and qualify alternate components while maintaining required voltage and insulation margins

  • Support sourcing discussions with procurement and supply chain teams

  • Drive parts consolidation initiatives without compromising HV safety compliance

  • Assess lifecycle, availability, and obsolescence risks

Compliance & Cross-Functional Collaboration

  • Participate in design reviews with a focus on HV safety, C&C compliance, and manufacturability

  • Support regulatory and safety compliance efforts (UL, IEC, and internal HV standards)

  • Assist with ECOs, layout revisions, and documentation control

  • Support prototype bring-up, validation testing, and transition to production

Qualifications:

  • Associate’s or Bachelor’s degree in Electrical Engineering, Electronics, or related field (or equivalent experience)

  • 5+ years of PCB design experience, including direct experience in MV or HV power electronics

  • Strong hands-on expertise in clearance and creepage (C&C) design and insulation coordination

  • Proficiency with PCB CAD tools (Altium Designer, Cadence Allegro/OrCAD, or equivalent)

  • Deep understanding of PCB fabrication and assembly processes for high-voltage designs

  • Experience generating production-ready documentation packages

  • Practical experience with BOM management and component sourcing

  • Familiarity with HV safety standards such as IEC 60664, IEC 61800, UL 508, UL 840, or similar

Bonus Qualifications:

  • Experience with conformal coating, potting, encapsulation, and insulation systems

  • Knowledge of partial discharge mitigation and electric field control techniques

  • Experience working directly with PCB fabricators on HV-specific constraints

  • Exposure to power topologies such as inverters, converters, drives, or MV power supplies

  • Exceptional attention to detail in safety-critical layout environments

  • Strong documentation discipline and cross-functional communication skills

 

Please note: This role requires working on-site 5 days a week. We do not offer hybrid or remote options.

Race & Ethnicity Definitions

If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows:

A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
