Firmware Engineer

The Firmware Engineer is responsible for designing, developing, testing, and maintaining firmware for TransTRACK's IoT and telematics devices. This role focuses on building reliable embedded systems for vehicle data communication, sensor integration, device management, and cloud connectivity. The successful candidate will work closely with Hardware, Platform, and QA teams to deliver high-performance, secure, and scalable products that operate reliably in demanding real-world environments.

Responsibilities

• Design, develop, and optimize high-performance embedded firmware using C/C++, Python, and other relevant programming languages for various MCU and SoC platforms, both bare-metal and RTOS-based.
• Develop and maintain low-level drivers and middleware for sensor integration and vehicle communication interfaces, including CAN/CAN-FD, J1939, I²C, SPI, UART, GPIO, and ADC.
• Implement and maintain communication protocols and networking stacks such as TCP/IP, MQTT, HTTPS, BLE, and cellular connectivity to ensure reliable device-to-cloud communication.
• Develop robust data acquisition and processing systems for telematics, fleet management, and IoT applications.
• Design and implement power management features, including sleep modes, watchdog mechanisms, and recovery strategies for power-related anomalies.
• Develop secure Firmware-Over-The-Air (FOTA) solutions with firmware validation, rollback mechanisms, and integrity verification.
• Perform firmware debugging, profiling, optimization, and root-cause analysis using oscilloscopes, logic analyzers, protocol analyzers, and software debugging tools.
• Create and execute unit tests, integration tests, and validation procedures to ensure firmware quality, reliability, and scalability.
• Collaborate closely with Embedded Hardware Engineers during schematic reviews, board bring-up, prototype validation, and production readiness activities.
• Develop factory testing utilities, manufacturing tools, and diagnostic features to support product deployment and maintenance.
• Investigate field issues, analyze device logs, and implement corrective actions to continuously improve product stability and performance.
