Job summary

Amazon is seeking a Hardware Development Engineer II to join the Power Electronics team in Seattle. You will design, develop, and validate 10KW+ high-voltage DC power electronics boards from concept to production, solving complex hardware engineering problems with strong system-level thinking.

You will drive architecture, define components, manage timelines, and collaborate with suppliers and contract manufacturers, delivering safe, reliable, and efficient hardware for Prime Air applications.

Qualifications

Bachelor’s degree in electrical engineering or equivalent.
4+ years hands-on experience with multi-layer power electronics PCB layout and design.
4+ years experience on high-voltage DC power systems rated at 10KW or above.
Experience developing power electronics boards from concept through production.
Proficiency with power electronics design tools (Altium, OrCAD, ECAD tools, MATLAB/Simulink).
Working knowledge of DO-160 and DO-274 design and test standards.
Understanding IP (Ingress Protection) rating requirements and design-for-environment principles.

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 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 balancing performance, cost, and schedule.
Improve team processes, tools, and methodologies; develop firmware, software, or scripts that aid development or testing of power electronics hardware.
