Bms Hardware Design professional

• 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 safe 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.

Qualifications, Experience, Skills

• B.E./B.Tech or M.E./M.Tech in Electrical/Electronics (or equivalent).
• 1-5 years of hands-on experience designing BMS or safety-critical automotive power electronics (48-800 V).
• Proven experience with BMS monitor/AFE ICs (e.g., TI BQ769x2 family, ADI LTC6811/6813): architecture selection, cell-sense front-end design, and balancing topologies.
• Strong PCB design skills in Altium/KiCAD: multilayer stack-ups, HV spacing rules, analog precision routing, and power integrity.
• Practical EMC/EMI design and debug: filtering, shielding, ground strategies; familiarity with CISPR 25 and ISO 11452 test methods.
• Knowledge of automotive electrical transients and protections (TVS, LC filters, surge/load-dump per ISO 7637-2).
• Comfortable with CAN/CAN FD, SPI, I C; ability to specify diagnostics and support firmware/HIL integration.
• Knowledge of GPS, GNSS, BLE, and other connectivity modules
• Lab proficiency: Oscilloscopes, Multimeter, DAQs, power analyzers, battery cyclers; safe HV handling and ESD practices.
• Familiarity with functional safety processes (ISO 26262), FMEA/FMEDA, requirements traceability tools (e.g., Polarion/DOORS). T
• Nice to have: Experience with cell modeling/SOC-SOH estimation collaboration, thermal design, conformal coating/sealing (IP ratings), and supplier PPAP/APQP.
