Job description

On-site in Greater Boston, MA Area

Our client is looking for an experienced engineering professional to contribute to the design and advancement of sophisticated power conversion systems and emerging electrical technologies. This is a true hands-on design opportunity for an engineer who wants deep technical ownership, challenging converter problems, and direct involvement from early architecture through production. This position offers the opportunity to contribute to innovative electrical technologies in a specialized development setting, partnering with seasoned engineers to support solutions for evolving and technically challenging markets.

This Role Offers:

• Competitive base compensation aligned with experience, with flexibility for exceptionally qualified senior-level talent.
• Annual stock-based merit opportunity in addition to base compensation.
• Comprehensive medical, dental, and vision benefits, paid time off, and a 401(k) match.
• Work in an innovation-focused engineering setting dedicated to developing emerging power technologies and creating new system designs.
• Exposure to advanced power technologies supporting demanding markets such as AI infrastructure, transportation, and aerospace.

Focus:

• Drive power conversion projects from early technical definition and analytical evaluation through physical build, performance verification, and final preparation for manufacturing.
• Design and analyze high-frequency AC/DC and DC/DC power conversion circuitry, selecting appropriate topologies, controls, and components for demanding performance targets.
• Develop magnetic solutions and solve challenges involving switching behavior, efficiency, stability, thermal performance, and power density.
• Apply simulation and analytical methods to evaluate circuits, validate design decisions, and resolve complex electrical performance issues.
• Drive PCB and layout decisions with careful attention to high-frequency behavior, signal integrity, noise, EMC, and overall converter performance.
• Translate product needs into clear engineering specifications, maintain records of key design choices, and develop methods for confirming performance and functionality.
• Work closely with engineering and manufacturing partners to troubleshoot hardware, refine designs, and transition products into production.
• Take an active role in early hardware development, supporting initial builds, performance testing, technical troubleshooting, and ongoing design refinement.

Skill Set:

• Bachelor’s degree in electrical engineering required, with a master’s degree in electrical engineering preferred.
• 5+ years of post-degree industry experience directly designing power electronics, power supplies, or converter products.
• Practical engineering background developing and working directly with power conversion hardware, including regulated power architectures, switching systems, and related electrical technologies.
• Proven ownership of power supply or converter designs, including making key engineering decisions rather than primarily supporting applications, testing, installation, integration, or evaluation activities.
• Strong technical depth in high-frequency magnetics, power-stage design and analysis, circuit simulation, PCB/layout practices, feedback and control, EMC, and component selection.
• Strong mathematical and analytical foundation with the ability to model, diagnose, and explain complex electrical behavior.
• Strong technical communication skills with the ability to clearly explain engineering approaches and demonstrate a thorough understanding of power conversion concepts during detailed technical discussions.
