The Hardware Development Engineer II will join the Power Electronics team, focusing on designing, developing, and validating high-power electronics systems. This role involves working on high-voltage DC systems rated at 10KW or more, contributing significantly to hardware engineering challenges. The team is responsible for delivering power systems for Prime Air's drones, ensuring safety and compliance with regulatory standards. The engineer will leverage their expertise to influence technical direction and improve product architecture.

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

• Design, develop, and test multi-layer power electronics board layouts for high-voltage DC systems 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.
• Ensure designs meet appropriate IP ratings for target deployment environments.
• Apply system-level thinking to understand how power electronics subsystems integrate with the broader product architecture.
• Partner effectively with cross-functional peers, suppliers, and contract manufacturers to build and validate designs.
• 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.
• Improve team processes, tools, and methodologies, and develop firmware or software that aids development or testing.
