Summary:

We are seeking an Embedded Firmware Engineer with 5–6 years of hands-on experience to develop firmware for a next-generation, battery-powered Tire Pressure Monitoring System (TPMS) sensor platform. The role is strongly focused on Bluetooth Low Energy (BLE), TPMS sensing and data transmission, low-power operation, and production-grade embedded C.

Roles & Responsibilities:

Develop and maintain embedded C firmware for resource-constrained TPMS sensor devices and receiver-side embedded modules or ECUs.

Implement TPMS application logic, including product state machines, measurement scheduling, sensor validation and filtering, diagnostics, and recovery.

Design BLE advertising flows for TPMS data, including GAP/GATT behavior, payload construction, OEM/customer-specific encoding, transmission timing, and Tx-power considerations.

Develop receiver-side firmware to receive, decode, validate, and process TPMS wireless packets, including sensor identification and association, message-integrity checks, signal-quality handling, diagnostics, and fault recovery.

Integrate pressure, temperature, acceleration, and battery-voltage sensing with BLE/radio, timers, NVM, diagnostics, and firmware-update services.

Optimize battery life using sleep/deep-sleep modes/LPM, wake-up sources, event-driven execution, and low-power measurement and transmission cycles.

Bring up, debug, and validate both sensor-side and receiver-side firmware on prototype hardware using JTAG, UART logs, vendor tools, and test setups, while collaborating with hardware, systems, and validation teams.

Professional & Technical Skills:

5–6 years of embedded firmware development experience, with strong hands-on C programming for microcontrollers.

Practical BLE experience, especially advertising, GAP, GATT, payload limits and formats, Tx power, RSSI, and low-power wireless trade-offs.

Experience with TPMS or automotive sensor-and-receiver systems involving pressure, temperature, acceleration, battery-voltage monitoring, motion detection, wireless data reception and diagnostics.

Experience developing firmware for receiver- or ECU-side embedded systems, including packet reception and decoding, sensor pairing or identification, data validation, diagnostics, and integration with vehicle or host software.

Strong MCU fundamentals, including interrupts, timers, watchdogs, memory constraints, fault handling, layered architecture, HAL, and driver abstractions.

Hands-on experience with UART, I2C, SPI, GPIO, ADC, flash, NVM, CAN/LIN, JTAG/debug probes, vendor SDKs, build tools, and Git.

Experience with low-power battery-operated devices, bootloaders, firmware updates, configuration management, static analysis, and production-oriented debugging.
