Senior Member of Technical Staff: Platform Electrical Engineer at Walden Robotics in Cambridge, MA

Job description

• We’re seeking an execution-driven Senior Electrical Engineer to be a technical leader in the hands-on implementation and delivery of our robot’s electrical systems. In this role, you will be an individual contributor responsible for designing, building, and testing critical subsystems including: power distribution, BMS, system level communications, and wire harnesses and ensuring these systems scale from early prototypes to robust, fault-tolerant production hardware. Candidates should bring deep experience delivering complex electromechanical products, along with demonstrated excellence in technical leadership, deep ownership, bias for action, delivery, and mentorship.

Responsibilities

• Own the electrical platform architecture for the humanoid robot, including battery systems, power distribution, grounding, and protection across the full machine.
• Design and deliver power management electronics, including high power capable switches, pre-charge circuits and monitoring systems.
• Design the robot's wire harness and interconnect system—architecture, connector selection, current/voltage-drop budgets, routing, and strain relief from prototype through production.
• Define and integrate battery systems in partnership with pack, BMS, and cell suppliers, addressing capacity, safe operating limits, charging, protection, and thermal considerations.
• Partner cross-functionally with mechanical, firmware, controls, and technicians to route power and signals through a tightly packaged robot, resolve integration issues, and optimize for mass, serviceability, and reliability.
• Lead system-level analysis and validation—power budgets, fault and safety analysis, load and thermal testing—and drive root-cause analysis of electrical issues across the platform.
• Drive the designs through DFM/DFA and production release with manufacturing and supply chain, establish platform electrical standards, and mentor engineers and technicians.

Requirements

• 7+ years of experience delivering complex electrical systems from concept through production (or MS + 5 years), including shipping hardware into volume production.
• Strong core electrical engineering skillset: schematic design, PCB layout (e.g Altium), power electronics/regulation, component selection, and system-level electrical integration.
• Demonstrated experience designing battery systems for high power products, including packs, BMS integration, charging, and safe operating and protection requirements.
• Deep understanding of power electronics fundamentals and working with high current systems. Experience designing power distribution for complex electromechanical systems, including protection, grounding, and fault analysis.
• Hands-on experience architecting and building wire harnesses and interconnect systems—connector selection, current and voltage-drop budgeting, harness routing, and fabrication.
• Strong communication, ownership, and a collaborative, cross-functional approach, with the ability to reason about the electrical system at the whole-product level.
• Direct experience with robotic systems, preferably humanoid and/or manipulation robots.
• Experience with high speed communications protocols such as Ethernet and PCIE.
• Experience with high-voltage or high-current battery systems and associated safety standards.
