Job Description : Firmware Engineer (Embedded Systems – Marine / ROV / USV Systems)
Role Overview
We are seeking a Firmware Engineer with expertise in FreeRTOS and ESP-IDF to design, develop, and optimize embedded software for real-time and marine system applications. The candidate will contribute to the development of ROV (Remotely Operated Vehicle) and USV (Unmanned Surface Vehicle) projects, ensuring robust performance in challenging aquatic environments.
Key Responsibilities
Firmware Development
Design, develop, and maintain firmware on microcontrollers using FreeRTOS and ESP-IDF.
Implement low-level drivers and communication protocols (I2C, SPI, UART, CAN, LoRa, etc.) and manage sensors, actuators, and power systems.
Optimize firmware for real-time control, low-latency communication, and reliability in marine / underwater applications.
Debugging & Testing
Use tools such as JTAG, oscilloscopes, and logic analyzers for debugging and validation.
Conduct unit, integration, and hardware-in-the-loop (HIL) testing for embedded systems.
Perform field testing, calibration, and system tuning for ROV and USV platforms.
Cross-Functional Collaboration
Collaborate with hardware and mechanical engineering teams for seamless ROV / USV integration.
Support prototype builds, sensor and thruster integration, and system validation in real-world water environments.
Participate in design reviews and contribute to system-level optimization.
Innovation
Identify performance bottlenecks and propose firmware optimizations for motor control, navigation, telemetry, and long-range communication (LoRa).
Contribute to advanced marine embedded architectures, thruster control algorithms, and communication frameworks (wired and wireless).
Required Skills
Strong expertise in FreeRTOS and ESP-IDF.
Proficiency in C / C++ (Python / Matlab a plus).
Experience with debugging tools (JTAG, oscilloscopes, logic analyzers).
Knowledge of microcontroller architectures (ESP32, Raspberry pi, Jetson Nano etc.) and LoRa-based communication modules.
Strong problem-solving and real-time system optimization skills.
Experience in sensor integration, motor driver control, and telemetry systems for ROV or USV applications.
Preferred Qualifications
Bachelor's / Master's in Electronics, Embedded Systems, Mechatronics, or Computer Engineering.
2–5 years of embedded firmware development experience.
Experience in ROV, USV, IoT, or Consumer Electronics projects.
Familiarity with marine communication protocols, LoRa mesh networks.
