24d • $117,300 - $160,000 • Onsite

About The Position

We are seeking a Hardware Development Engineer II to join our Power Electronics team. 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.

Requirements

• 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 (e.g., Altium, OrCAD, ECAD tools, 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

Nice To Haves

• Master's degree or Ph.D. degree in Electrical Engineering or related field
• Experience leading vendor engagements and manufacturing partner discussions for power electronics assemblies.
• Familiarity with thermal simulation, power integrity analysis, and high-voltage creepage/clearance design rules.
• Experience with rapid prototyping techniques and low-volume manufacturing of power electronics hardware.
• Track record of delivering stable, performant hardware solutions that meet cost and quality targets.
• Ability to decompose complex power system challenges into well-defined component-level design tasks.
• Experience with reliability testing, HALT/HASS, and failure analysis of power electronics systems.
• Demonstrated ability to influence technical decisions across teams and communicate complex trade-offs to non-technical stakeholders.
• Contributions to intellectual property (patents, trade secrets) in the power electronics domain.

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.

Benefits

• health insurance (medical, dental, vision, prescription, Basic Life & AD&D insurance and option for Supplemental life plans, EAP, Mental Health Support, Medical Advice Line, Flexible Spending Accounts, Adoption and Surrogacy Reimbursement coverage)
• 401(k) matching
• paid time off
• parental leave
• sign-on payments
• restricted stock units (RSUs)
