About Techlanz

Techlanz is a Bengaluru based start-up founded by IIT alumni with a core focus on high performance battery packs for drone applications

Position OverviewLead the design, delivery and maintenance of safety-critical embedded firmware for Battery Management Systems (BMS) across cell, module and pack levels. Own firmware architecture, requirements-to-release execution, cross-team integration (HW, algorithms, testing, cloud/telemetry), and mentor a small team of firmware engineers.

Key responsibilities

● 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/I²C 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)

● Robust 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)

Skills

● C,C++ , Python

● BMS firmware,

● ST/TI/NXP/MPS

● BareMetal Programming, FreeRTOS, AUTOSAR Classic/Adaptive

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

● CAN / CAN-FD, OBD/UDS, UART, SPI, I²C, Ethernet, BLE, MQTT

● OTA/FOTA

● Git, CI/CD, static analysers, unit test frameworks, debuggers (JTAG).

● HIL, FMEA, ISO26262, cybersecurity
