Embedded Firmware Development Engineer

Role Summary:

We are seeking an Embedded Firmware Engineer with 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.

Key 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.

Required Skills & Focus Areas:

- 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.
