Staff Reliability Engineer - 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.  

Responsibilities: 

  • Lead reliability efforts across the product lifecycle—from concept to field deployment for SSTs. Develop robust reliability design guidelines and research failure mechanisms to ensure durability and accelerate time to market.

  • Apply reliability models (e.g., Fault Trees, block diagrams) and lead Design FMEAs to identify risks early, influence engineering decisions, and shape test coverage.

  • Champion reliability in design reviews by clearly communicating risks to all stakeholders and mitigation plans at each phase of development.

  • Specify and execute reliability test plans using physics-of-failure principles, defining system vs component-level testing with defined sampling and durations.

  • Analyze accelerated life tests and field performance to refine reliability models, predict product longevity, and implement corrective actions. Resolve failures through root cause analysis using advanced diagnostic techniques.

  • Grow and mentor a reliability engineering team to support development and continuous improvement.

  • Collaborate with design, manufacturing, and quality teams to define reliability targets, assess program risks, and embed feedback into future iterations.

  • Influence supplier selection by setting clear reliability validation standards.

  • Monitor fleet usage and operating conditions to enable predictive health insights, reduce field failures, and refine long-term reliability strategies.

  • Travel to different facilities worldwide, collaborating with teams and deploying our solutions.

Qualifications: 

  • Advanced degree (Master’s or PhD) in Electrical or Mechanical Engineering.

  • Deep expertise in power electronics fundamentals, focusing on high voltage and high power systems.

  • Proficiency in accelerated testing methods, including governing equations and physics of failure for electrical and mechanical failure mechanisms.

  • Strong understanding of reliability statistics, including Weibull distribution, Maximum Likelihood Estimation, Bayesian methods, and Monte Carlo analysis.

  • Hands-on experience with failure analysis techniques, such as optical microscopy, SEM, CSAM, X-ray, cross-sectioning, and EDX.

  • Expertise in reliability tools such as ReliaSoft Synthesis Platform (Weibull++, BlockSim, ALTA, RGA, xFMEA) or equivalent.

  • Experience integrating electronic CAD and mechanical CAE data into 3D finite element models (e.g., using Sherlock or similar tools).

  • Experience shipping high-volume products, with a strong understanding of reliability challenges in scaled manufacturing and deployment.

  • Proficiency in programming languages for data analysis and reliability modeling.

  • Proven leadership experience in building and managing high-performing engineering teams.

  • Excellent communication skills to articulate reliability risks and requirements to cross-functional teams and suppliers

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
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

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.
