Reliability Engineering Lead

About the company

Heron Power designs and manufactures high-capacity solid-state transformers that streamline power conversion for data centers, renewable energy, and grid-scale battery applications.

About this role

WHAT TO EXPECT Heron Power is a startup company building cutting-edge power electronics for the 21st-century grid. We aim to debottleneck the growth of electricity generation and consumption with scalable, innovative, and less costly hardware solutions, accelerating the electrification of everything. Our first goal is to build better converters (inverters & rectifiers) to connect large-scale renewables, storage, and loads to the grid. Heron Power’s leadership team is made up of seasoned veterans who have designed and shipped gigawatts of power conversion products over the past decade. We understand that no one individual knows everything. We will all learn a lot together and from each other. We strive to build a collaborative, enriching environment conducive to personal, technical, and career growth. You can expect to work in a dynamic and collaborative environment, driven by first principles engineering, solving difficult problems. JOB OVERVIEW Reliability is at the core of our company and everything we design. We stand behind our products with a full lifetime warranty across all applications—a commitment that only holds up if reliability is engineered in from first principles, not bolted on at the end. As our Reliability Engineering Lead, you will drive reliability-by-design across Heron Power’s power electronics products—from concept through field deployment—grounded in Physics of Failure (PoF) and Design for Reliability (DFR) principles rather than generic stress screening. You’ll set reliability strategy at the corporate level and partner across Electrical, Mechanical, Firmware/Software, Quality, Product, and Commercial teams to ensure it’s designed in at every level, from warranty terms through lifecycle cost of ownership. HOW YOU WILL CONTRIBUTE - Define product reliability requirements, balancing target reliability and failure-rate metrics against cost, schedule, and manufacturability constraints - Set reliability strategy and goals at the corporate level, aligning engineering, product, and manufacturing teams around shared reliability targets and roadmaps - Apply Physics of Failure and Design for Reliability principles throughout the product development lifecycle, identifying dominant failure mechanisms early and driving design decisions that mitigate them before hardware exists - Derive mission profiles from real-world use conditions and translate them into accelerated life test (ALT) calculations—acceleration factors, sample size, and test duration - Build and maintain reliability models (Weibull/lifetime distributions, FMEA, fault tree analysis) to predict failure modes and quantify confidence levels for design decisions - Own field reliability strategy, closing the loop between field return/failure data and our design, test, and mission-profile assumptions - Partner with Product and Commercial teams to define warranty terms, translating our full lifetime warranty commitment into concrete design targets - Own the lifecycle cost as a design attribute—driving decisions on service, repair, and system architecture that keep products highly available and cost-effective to operate over decades, beating the competition on lifetime cost of ownership - Partner directly with Electrical, Mechanical, and Firmware/Software engineering teams, as well as the Quality organization, to ensure reliability is designed in at the component and system level - Mentor and potentially lead a team of reliability engineers, setting technical direction and reviewing mission-profile derivations, ALT plans, and findings WHAT MAKES THIS ROLE DIFFERENT - This is a strategy-setting role, not just an execution role—you define reliability requirements and set corporate-level goals rather than apply an existing process. - You'll have the challenge to build and scale a reliability engineering function as Heron grows, rather than executing within one that's already established. - You own the full arc from physics to business outcome—mission profiles → ALT plans → field data → warranty terms—closing the loop between design assumptions and real-world performance. - You’ll have the license to build and scale a reliability engineering function as Heron grows, rather than executing within one that’s already established. WHAT YOU WILL BRING We have a short list of must-have requirements. We prioritize a strong grip on first principles, hands-on skills, and a sense of initiative. Domain-specific knowledge and experience will help determine the career level for each hire. MUST-HAVE REQUIREMENTS - Bachelor’s or advanced degree in Mechanical, Electrical, Reliability, or related Engineering discipline - Demonstrated depth in Physics of Failure (PoF) and Design for Reliability (DFR) methodologies, grounded in underlying failure mechanisms (e.g., fatigue, thermal, electromigration, corrosion) - Hands-on experience deriving mission profiles from field/use-condition data and translating them into accelerated life test calculations (acceleration factors, sample size, duration) - Experience defining reliability requirements that explicitly account for cost, schedule, and business risk tradeoffs - Strong grounding in reliability statistics—Weibull analysis, censored data handling, confidence intervals, FMEA/FTA - Demonstrated ability to work cross-functionally with Electrical, Mechanical, and Firmware/Software teams and Quality organizations - Experience designing for maintainability, serviceability, and system availability—translating those attributes into concrete design decisions - Demonstrated experience partnering with Product and Commercial teams to connect warranty/business commitments with engineering design targets NICE-TO-HAVES - Experience owning field reliability strategy end-to-end - Prior experience setting reliability strategy or goals at an organizational (not just program) level - Published research or industry papers in reliability or ph
