In this role, you will be a significant and autonomous contributor, solving difficult hardware engineering problems related to high-power electronics systems. You will design, develop, and validate power electronics boards from concept through production, working on 10KW+ high-voltage DC systems that push the boundaries of performance, reliability, and efficiency. This position requires an engineer who demonstrates strong technical depth in power electronics while also exhibiting the system-level thinking and influence characteristic of our most impactful contributors. ### Key job responsibilities - Design, develop, and test multi-layer power electronics board layouts for high-voltage DC systems (10KW+), from initial concept through volume production release. - Define and execute power electronics component architecture, including topology selection, component specification, and thermal management strategies. - Lead the development of test plans that validate designs against DO-160 and DO-274 standards, ensuring electromagnetic compatibility, environmental resilience, and functional safety. - Ensure designs meet appropriate IP (Ingress Protection) ratings for target deployment environments. - Apply system-level thinking to understand how power electronics subsystems integrate with and influence the broader product architecture. - Partner effectively with cross-functional peers, suppliers, and contract manufacturers to build and validate designs, driving alignment on technical trade-offs. - Deliver accurate time-based estimates for engineering tasks and manage design milestones through the product development lifecycle. - Create and maintain high-quality design documentation including schematics, specifications, analysis reports, and test results. - Contribute to design reviews, providing constructive technical feedback to teammates and cross-functional partners. - Identify risks and defects early in the design phase and proactively propose solutions that balance performance, cost, and schedule. - Improve team processes, tools, and methodologies; develop firmware, software, or scripts that aid development or testing of power electronics hardware. ### A day in the life You independently drive the design and delivery of power electronics hardware, making sound trade-offs between performance, cost, manufacturability, and schedule. Your test plans thoroughly validate designs and efficiently address system integration challenges. You think in terms of the system, not just individual components, and proactively work to improve the overall product architecture. Your work is consistently high quality, meeting safety, regulatory, and reliability standards. You influence your team's technical direction and are recognized as a go-to resource for power electronics expertise. ### About the team The New Experimental Technology (NEXT) Electric Propulsion Subsystem (EPS) organization conducts technology research, design and development of the power system for Prime Air’s drones. We are responsible to deliver an EPS and hardware components that safely supports 15-minute drone delivery and is certifiable by the FAA and EASA regulators. Our work spans the full product lifecycle, from early-stage research and concept development through detailed design, prototyping, testing, and certification support. The EPS is a critical system enabling Prime Air’s autonomous delivery operations, providing the electrical power generation, storage, distribution, and propulsion capabilities required for safe and reliable flight. ## At a glance - Posted by the employer: Oct 22, 2026 - First seen by OpenNash: Oct 25, 2026 - Last checked: Nov 1, 2026 - Listed for: 10 days - Location: US, WA, Seattle[Apply on Amazon’s careers site →](https://www.amazon.jobs/en/jobs/10586930/sr-power-electronics-engineer-prime-air-electric-propulsion-subsystem) ## Hiring at Amazon - Open jobs: 19,174 - New in the last 7 days: After two weekly collections - Tracked since: Jul 10, 2026 [All Amazon jobs](https://jobs.opennash.com/companies/amazon/) · [Weekly hiring report](/reports/hiring/) ## More jobs at Amazon ### [ADC Engineer II, Amazon Dedicated Cloud Engineering - Support Engineering](https://jobs.opennash.com/companies/amazon/jobs/6e2bf60cf0bce0914d3d/) US, WA, Seattle ### [ADC Engineer, S3 ADC, S3+Glacier Unique Regions](https://jobs.opennash.com/companies/amazon/jobs/623546f687d50bfbe4dc/) US, WA, Seattle ### [Acquisition Business GTM/BD Lead, AGS North America](https://jobs.opennash.com/companies/amazon/jobs/2d97c848bf5005837e30/) US, WA, Seattle ### [Amazon Dedicated Cloud Engineer, Platform Engineering and Emerging Technologies (PEET)](https://jobs.opennash.com/companies/amazon/jobs/9c874527552a3b78cfe7/) US, WA, Seattle ### [Analyst, Network Strategy and Performance, Network Strategy and Performance](https://jobs.opennash.com/companies/amazon/jobs/b92e15f5be52bd37c801/) US, WA, Seattle ## Similar jobs at other companies ### [Electronics Engineer IV, Power Electronics](https://jobs.opennash.com/companies/lockheed-martin/jobs/c7875caa80fa67be2561/) Lockheed Martin · Kennedy Space Center, FL ### [Lead Power Electronics Engineer - Power Conversion](https://jobs.opennash.com/companies/eaton/jobs/597a1a3fd247dfb34f62/) Eaton · Menomonee Falls, Wisconsin, USA ### [Lead Power Electronics Engineer](https://jobs.opennash.com/companies/eaton/jobs/1fa9db379a220f87b3ae/) Eaton · Menomonee Falls, Wisconsin, USA ### [Power Electronics Engineer](https://jobs.opennash.com/companies/bae-systems/jobs/82d9c76070ba178a544b/) BAE Systems · Endicott, New York, United States ### [Senior Power Electronics Engineer - VFDs](https://jobs.opennash.com/companies/abb/jobs/1158522839028ec0e0bf/) ABB · New Berlin, Wisconsin, United States of America OpenNash lists jobs from employers’ own careers sites and does not handle applications.
