Staff/Sr Staff Reliability Engineer - Power Electronics

Job DescriptionJob Description

Company Overview:  

Amperesand is disrupting industrial power with the first commercialized Solid State Transformer systems. Solid State Transformer 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 seeking mission-driven team members who are 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:

At Amperesand, you will lead the reliability lifecycle from concept through design, testing, manufacturing, and field deployments, while ensuring the product meets stringent reliability requirements to support the world's critical infrastructure.

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).
• Proven experience shipping high-volume products, with a strong understanding of reliability challenges in scaled manufacturing and deployment.
• Proficiency in programming 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
