Position Overview

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 product ion.

Job Responsibilities

● 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 explicit 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.

● Solid 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.
