We are recruiting for a Senior Electrical Engineer on the Power Tools Team. The role will be based in Palm Beach Gardens, Florida, Raynham, Massachusetts, or Boston Massachusetts.

Purpose:

The Senior Electrical Engineer will develop embedded firmware tightly coupled to electrical hardware for next-generation surgical power tools, batteries, chargers, motor controllers, handpieces, accessories, and related electromechanical equipment. This is primarily an electrical engineering and embedded hardware role, with significant responsibility for low-level embedded firmware written in C and C++. The engineer will participate in electrical designs from early feasibility and architecture through schematic development, PCB implementation, board bring-up, firmware integration, design verification, regulatory support, manufacturing transfer, and product lifecycle support.

The role requires strong hands-on capability in circuit design, embedded microcontroller systems, power electronics, battery-powered products, motor control, and laboratory troubleshooting.

• Design and develop surgical power tools, motor controllers, battery systems, chargers, handpieces, accessories, and supporting equipment.
• Define electrical system and subsystem architectures, including power distribution, motor drive circuitry, safety circuits, sensing, communications, and embedded control hardware.
• Design and develop electronics and embedded controls for three-phase brushless DC motor systems.
• Translate product and system requirements into electrical requirements, interface definitions, component specifications, schematics, PCB designs, and verification strategies.
• Perform design calculations, simulations, component derating analyses, tolerance analyses, power budgets, timing analyses, and technical trade studies.
• Conduct and support architecture reviews, schematic reviews, PCB layout reviews, component reviews, and cross-disciplinary design reviews.
• Maintain ownership of electrical systems from initial concept and prototype development through verification, regulatory approval, manufacturing release, and post-market support.
• Develop embedded firmware interfaces to battery-management ICs, charging circuits, temperature sensors, current sensors, pack identification, authentication, and communication devices.
• Support battery safety, reliability, verification, transportation, and regulatory…
