Lead end-to-end firmware development for BMS ECUs (cell/board/module/pack level): architecture, implementation, code reviews, CI and releases.

Define and translate system and safety requirements (functional non-functional) into firmware requirements and test cases; support requirements management.

Develop drivers, bootloader, WDT, Fault Management, diagnostics, Sensor interface GPIO control

BMS Parameter configuration,

Implement and maintain battery-control algorithms interfaces (SOC/SOH/State estimation, balancing control, thermal management controls, Fault Management) in firmware; collaborate with algorithm/controls team.

Design and own BMS communications stack (CAN/CAN-FD, LIN, UART, Ethernet, SPI/I C to sensors/ICs) and data telemetry uplinks (MQTT/HTTPs).

Lead hardware-firmware integration, calibration and validation: lab testing, MIL/SIL/HIL, automated test harnesses and production test procedures.

Ensure firmware satisfies safety (ISO 26262/ASIL where applicable), EMC, and functional safety requirements; coordinate with safety engineers for FMEA and safety cases.

Improve firmware development process: coding standards, static analysis, unit integration testing, CI/CD, over-the-air (OTA) update design and secure boot.

Drive supplier and vendor interactions for BMS ICs, charge controllers, and test equipment; create firmware integration plans for suppliers.

Actively participate in battery homologation activities and proactively resolve the issues

Qualifications

3+ years of embedded firmware experience, with proven ownership of modules or projects
and demonstrated technical impact (individual contributor or team leadership exposure)

Strong C programming skills (bare-metal / RTOS); experience with FreeRTOS, AUTOSAR, or equivalent.

Knowledge of FreeRTOS, baremetal programming, Task scheduler

Deep domain experience in Battery Management Systems or battery-adjacent firmware (cell monitoring ICs, balancing, pack-level control).

Hands-on experience with automotive/industrial field buses (CAN/CAN-FD, LIN, Ethernet) and diagnostics.

Experience with firmware development lifecycle: version control (git), CI pipelines, unit testing frameworks, code review practices.

Solid understanding of battery electrochemistry concepts (SOC/SOH basics, cell balancing implications) and thermal management.

Practical exposure to test validation: HIL, MIL, automated test benches and debug tools (JTAG/SWD, oscilloscopes, protocol analyzers).

Communication skills to interface with systems, hardware, algorithm and product teams; English fluent.

ISO 26262 / IEC 61508 safety experience, familiarity with safety case and FMEA deliverables.

Experience with OTA update frameworks, secure boot, hardware root-of-trust and cryptographic signing.

Experience porting/optimizing firmware across MCUs (NXP, STM32, Renesas, MPS) or BMS IC vendors.

Experience in AFE and ADC modules

Data pipelines/telemetry knowledge (edge-to-cloud messaging, data compression, telemetry security).

Knowledge of GNSS, GPS, BLE and other connectivity module is preferred

Familiarity with model-based design workflows (Matlab/Simulink MIL/SIL/HIL integration)
