Job description

Join our Electrification hardware team to design, validate, and productize Battery Management System (BMS) electronics for Drone Applications. You will architect robust analog front-ends, protection circuits, and pack controllers; select automotive-grade components; and deliver schematics/PCBs that meet functional safety (ISO 26262), reliability (AEC-Q100/200), EMC (CISPR 25/ISO 11452), and OEM compliance requirements for series production.

Job Responsibilities

KEY DELIVERABLES OF THE ROLE

• 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.
• Assemble, wire, and solder prototype and production electronic circuit boards (through-hole and SMD)
• 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/I²C, 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.
• Perform board bring-up, functional testing, and troubleshooting of PCBs, modules, and subsystems
• Use lab equipment (multimeter, oscilloscope, power supply, function generator, logic analyzer) for measurement, debugging, and validation
• Support design engineers with circuit debugging, rework, and failure analysis
• Maintain test setups, fixtures, and calibration of lab instruments
• Document test results, issues, and observations in lab notebooks/reports
• Build and test wiring harnesses, connectors, and cable assemblies
• Support EMI/EMC, thermal, and environmental testing as required
• Inspect incoming components and boards for quality/defects (visual and continuity checks)
• Maintain inventory of components, tools, and lab consumables
• Follow ESD-safe handling practices and lab safety protocols
• Assist in setting up and running automated/manual test procedures
• Support firmware flashing/programming of boards during testing (if applicable)
• Collaborate with R&D/production teams to resolve hardware issues and improve yield

Desired Skills

• Basic understanding of BMS (Battery Management System), SOC, OCV, Charge / Discharge and protection functions.
• Proficiency with oscilloscopes, DMMs, power supplies, and other bench equipment
• Hands‑on soldering (fine‑pitch SMD and THT), rework, and PCB assembly
• Basic understanding of analog/digital circuits, power supplies, and communication protocols (I2C, SPI, UART, CAN)
• Ability to read schematics and datasheets and find alternate for obsolete parts.
• Good documentation and troubleshooting skills
• Basic scripting/programming knowledge (Python, MATLAB) is a plus

Qualifications, Experience, Skills

• B.E./B.Tech or M.E./M.Tech in Electrical/Electronics (or equivalent).
• 1-4 years of hands‑on experience designing BMS or safety‑critical automotive power electronics (48-800 V).
• 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, I²C; 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.
