Senior Electrical Engineer

Overview

Lead the electrical development of systems supporting Mevion’s S250 proton therapy platform, where high-reliability engineering directly contributes to cancer-treatment delivery. You will own challenging high-voltage and power-electronics subsystems from architecture through verification, working closely with multidisciplinary teams and mentoring developing engineers.

• Lead the design and development of electrical subsystems including power electronics, control circuitry, and high-voltage systems.
• Perform circuit analysis, schematic design, and PCB layout review for complex electrical assemblies.
• Develop and execute electrical system test plans, failure analysis, and design verification protocols.
• Authors and maintains electrical design documentation including schematics, BOMs, and engineering change orders.
• Provide technical leadership and mentorship to junior engineers on electrical design methodology and standards.
• Collaborate with mechanical, software, and physics engineering teams to ensure electrical subsystem integration.
• Troubleshoot and resolve electrical issues during manufacturing, commissioning, and field operation.
• Ensure electrical designs comply with applicable safety standards including IEC 60601 and relevant EMC requirements.
• Willingness and ability to travel (5-10%) domestically and internationally as business needs require.

• BS/MS in Electrical Engineering required with 5+ years' experience, and hands-on product-development experience for a complex product. Expertise in either high-voltage power electronics, AC/DC power systems or precision analog design.
• Proven experience in performing all design and development stages including schematic capture, layout, design, verification and documentation.
• Proficiency in PCB design tools (e.g., Altium, OrCAD) and circuit simulation software.
• Self-sufficiency in planning and driving projects to conclusion, as well as meeting performance and cost objectives in a timely fashion with a high level of innovation, quality and efficiency.
• The ability to easily transition from one project to the next with little direct supervision.

• Experience in the design and manufacture of Medical Capital Equipment systems or another regulated product development environment (aerospace, defense).
• EC 60601, EMC, medical-device, aerospace, defense, industrial equipment, or other regulated-product experience.
• RF experience.
• Demonstrated ability to leverage modern AI tools in innovative ways to improve engineering effectiveness, solve technical challenges, or create business value.

• Regular standing and walking in lab or engineering areas.
• Typical office environment.
• Frequent use of hands to handle tools, instruments, and small parts.
• Occasional lifting or moving of equipment and materials up to 35 lbs (16 kg).
• Occasional bending, stooping, or reaching to access work surfaces and equipment.
• Combination of office and lab/engineering environments.
• Work around equipment, tools, and test setups with moderate noise.
• Use of appropriate PPE (e.g., safety glasses, lab coats, gloves) as required by task and safety procedures.
• May need to work in the vicinity of high magnetic fields.
