Job Description
We are seeking a Sr. Firmware Developer to lead firmware design and development for our next-generation automotive IoT device, ITUS. This role involves building robust, secure, and high-performance embedded systems that collect, process, and transmit vehicle data in real time.

You'll work closely with our hardware, backend, and data teams to create intelligent edge devices that power vehicle analytics, diagnostics, and connected mobility applications

The ideal candidate will have a strong technical background across full-stack web development, automation platforms, and AI/ML integration workflows. You will guide a diverse team of developers with different technical skill sets, ensure smooth collaboration across teams, manage deployments, act as the key technical point of contact for the sales and marketing team, and handle customer discussions.

Key Responsibilities

• 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.

Qualifications
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.

Preferred Qualifications:

• Experience with diagnostic protocols (ISO , ISO and vehicle ECU communication.
• Exposure to automotive-grade hardware design and environmental validation.
• Knowledge of functional safety (ISO or secure communication standards.
• Experience developing custom test automation scripts in Python or C#.
