Senior Staff Electrical Engineer (On-site)

Job description

Job responsibilities

• Lead the Bolt hardware team of mechanical and electrical engineers: set the electrical architecture and work with the mechanical team to set the mechanical architecture, plan prototype builds and the test program, run…
• Own the hardware side of AMR safety certification with Functional Safety: the certification plan, the safety functions and their evidence, and the test-lab campaigns for ISO 3691-4, ANSI/RIA R15.08, and UL 3100
• Contribute as an IC where your contributions can best be utilized
• Specify, select, and integrate the battery pack, BMS, and charger from a battery manufacturer: requirements, vendor evaluation, BMS communication (CAN), charge and discharge limits, and pack-level safety and…
• Drive key architecture and component decisions through requirements and trade studies (pack capacity, drive configuration, peak and regenerative current, thermal)
• Do the hands-on, technically deep work: schematic capture, high-current PCB layout, board bring-up, test plans, and root-cause debugging on the bench and on the robot
• Design for safety and certification: fault analysis, derating, and the power-cutoff paths that functional safety relies on (ISO 13849, IEC 62133 / UL 2271 at the pack interface, EMC)
• Hire, mentor, and grow the hardware team, and be the primary technical contact for battery, charger, drive, and PCBA vendors

Job requirements

• Experience: Bachelor's or graduate degree in Electrical Engineering (or related) and 10+ years designing, building, and testing power systems and PCBAs, including leading the hardware of an AMR, AGV, or similar mobile…
• AMR Safety Certification: You have taken an AMR or similar mobile machine through third-party safety certification (ISO 3691-4, ANSI/RIA R15.08, UL 3100), including ISO 13849 safety functions, the evidence package, and…
• Power Depth: Mastery of high-current distribution, pre-charge and protection circuits, DC/DC conversion, motor-drive power stages, and regen and bus-capacitance behavior
• Battery Integration: Working knowledge of BMS behavior (balancing, SoC/SoH, protection limits, CAN interface) and how to specify, qualify, and integrate a vendor pack and charger
• Compliance: Working knowledge of IEC 62133 / UL 2271 at the pack interface and EMC (IEC 61000 series) with pre-compliance debugging
• Leadership: You have led engineers through an NPI cycle and made them better; you give direct, specific design feedback
• Tool Fluency: Proficient in Altium Designer for schematic capture and multi-layer, high-current layout; LTspice or similar for simulation; Python for test automation
• Debugging Mastery: Scope, current probe, thermal camera, and bench instruments; you document what you find and converge on a fix quickly
