📋 Description

• Architect, design, and implement firmware for Datakrew’s automotive IoT edge devices using ARM-based microcontrollers (e.g., STM32, ESP32). • Develop and optimize CAN / CAN FD, OBD-II, and UDS communication stacks for vehicle data collection. • Implement real-time data acquisition, logging, and edge analytics for on-vehicle insights. • Work on wireless connectivity (4G/LTE, WiFi, BLE, GNSS) and secure cloud data transmission. • Design and maintain bootloaders, OTA (Over-the-Air) update mechanisms, and secure firmware upgrade systems. • Develop firmware-level database integration for logging and synchronizing data with backend systems (e.g., embedded database, flash-based logs, or direct API sync with cloud databases). • Implement data buffering, compression, and fail-safe log storage to handle offline or low-connectivity scenarios. • Collaborate with backend engineers to define data schemas, synchronization logic, and retention strategies. • Work with hardware teams for board bring-up, validation, and peripheral driver development (UART, SPI, I2C, SDIO). • Ensure compliance with automotive communication and safety standards. • Lead debugging, validation, and testing efforts to ensure firmware reliability and field performance. • Mentor junior engineers and maintain comprehensive technical documentation.

🎯 Requirements

• Bachelor’s or Master’s degree in Electronics, Electrical, or Computer Engineering. • 5+ years of experience in embedded firmware development in C/C++. • Strong understanding of automotive communication protocols – CAN, OBD-II, UDS, ISO-TP. • Hands-on experience with RTOS (FreeRTOS, Zephyr, etc.) and real-time system design. • Familiarity with cellular, BLE, and GNSS/GPS module integration. • Experience with local database systems (e.g., SQLite, lightweight file-based storage) and integration with cloud databases (PostgreSQL, AWS DynamoDB, or TimescaleDB) for telemetry and logs. • Familiarity with IoT data ingestion and APIs (MQTT, HTTPS, REST) for remote log upload. • Strong debugging and testing experience using oscilloscopes, logic analyzers, and JTAG tools. • Experience with firmware update systems (bootloaders, OTA, DFU) and secure data handling. • Proficient with Git, CI/CD pipelines, and structured firmware release processes. • Good understanding of low-power design, flash memory management, and persistent data logging.

🏖️ Benefits

• Opportunity to work on next-generation connected vehicle technologies. • Exposure to end-to-end automotive IoT ecosystems — from embedded devices to cloud databases. • Collaborative, innovation-driven environment working with hardware, firmware, and cloud teams. • Competitive salary, flexible work options, and performance incentives. • Career growth in a fast-evolving automotive IoT and telematics domain.
