- Architect smart BMS hardware from requirements through release.
- Execute schematic capture, component selection, and simulation (SPICE, etc.) for mixed-signal PCB designs.
- Create PCB layouts, ensuring adherence to best practices for signal integrity, power integrity, and EMC/EMI compliance.
- Design and implement robust battery monitoring, cell balancing, and protection circuits using high-precision analog front-ends (AFEs) and microcontrollers.
- Conduct comprehensive design-for-manufacturing (DFM), design-for-test (DFT), and failure mode and effects analysis (FMEA).
- Develop and execute rigorous hardware validation and verification plans, including functional, environmental, and stress testing.
- Design to ISO 26262 hardware safety goals (ASIL allocation, safety mechanisms, diagnostics coverage) and generate work products (HARA inputs, FMEDA data to support system teams).
- Select and integrate automotive-grade components (BMS AFE/monitor ICs, shunts/Hall sensors, isolated drivers, power supplies) ensuring AEC-Q qualification and derating compliance.
- Own PCB schematic/stack-up/layout (creepage/clearance, Kelvin sensing, star-grounds, guard rings, differential routing) and run SPICE/thermal simulations prior to build.
- Plan and execute V&V; for EMC/EMI; drive design changes to pass at component and vehicle level.
- Optimize hardware designs for low power consumption, thermal management, and long-term reliability.
- Implement robust pack power stages (contactor drivers, pre-charge circuits, bleed/balance paths) and coordinate protected states for faults (SCD/OC/OV/UV/OT).
- Bring-up and characterize prototypes using scopes, power analyzers, SMUs, battery cyclers; create test plans, logs, and clear DfX actions (DFM/DFT/DFR).
- Integrate comms interfaces with firmware teams-Drone CAN, SPI/I C, UART, BLE; define diagnostics, boot-loaders,



and pack-level serviceability hooks.
- Deliver manufacturing-ready documentation (BOM with AML, fab/assembly notes, test fixtures, EOL criteria) and support PPAP/APQP with suppliers.
- Perform design risk analysis (FMEA/FMECAs), support safety case evidence, and contribute to compliance reviews and audits.
