Embedded Software Engineer

Job Summary

The Embedded Systems Engineer will design, develop, test, and maintain firmware and embedded software for IoT gateway and edge computing products. This role demands a strong foundation in Linux-based embedded development, real-time communication protocols, hardware interfacing, and cloud connectivity, with a preference for candidates familiar with industrial condition monitoring or predictive maintenance domains

Key Responsibilities

Embedded Software Development

• Design and develop embedded Linux applications in C, C++, and Python for Raspberry Pi (RPi/RSP) and Toradex Gateway/Edge platforms.
• Write optimized, production-grade code adhering to embedded software best practices and coding standards.
• Implement and maintain device drivers, kernel modules, and BSP customizations for target hardware.
• Develop and integrate firmware for real-time and Linux-based microcontroller/microprocessor systems.

IoT Gateway & Edge Computing

• Build and deploy IoT gateway solutions for data acquisition, edge processing, and cloud transmission.
• Develop MQTT-based telemetry pipelines for sensor data from industrial field devices.
• Implement Modbus RTU/TCP, CAN, RS-485, and other industrial protocol stacks for device communication.
• Configure and manage network interfaces including Ethernet, TCP/IP, Wi-Fi, and cellular for remote deployments.

Hardware & Protocol Integration

• Interface with peripheral hardware via SPI, I2C, UART, GPIO, and USB buses.
• Collaborate with hardware engineers to validate PCB designs, schematics, and bring-up new boards.
• Debug and resolve hardware-software integration issues using oscilloscopes, logic analyzers, and JTAG/SWD debuggers.
• Develop hardware abstraction layers (HAL) to decouple application logic from hardware specifics.

Linux & System Configuration

• Configure and maintain embedded Linux systems including kernel, device tree, bootloader (U-Boot), and root filesystem.
• Write and maintain Linux shell scripts for system configuration, automation, diagnostics, and deployment tasks.
• Manage system services, network configuration, and security hardening on embedded Linux targets.

Testing, Debugging & Quality

• Design and execute unit tests, integration tests, and system-level validation for embedded software.
• Identify, reproduce, and resolve software defects in embedded Linux and bare-metal environments.
• Maintain comprehensive documentation including design specifications, test reports, and release notes.
• Participate in code reviews and contribute to team coding standards and quality processes.

Collaboration & Delivery

• Work closely with mechanical, electrical, and software teams in an Agile/Scrum development environment.
• Manage source code and releases using Git version control and branching strategies.
• Provide technical inputs for product roadmap discussions and customer-facing deployments.
• Support field installation, commissioning, and remote troubleshooting of deployed devices when required.

Required Technical Skills

Programming Languages

• Proficient in C and C++ for embedded and systems-level development.
• Working knowledge of Python for scripting, automation, and rapid prototyping.
• Strong understanding of memory management, data structures, and real-time constraints in embedded contexts.

Embedded Platforms

• Proven hands-on experience with Raspberry Pi (RPi 3/4/5, RPi CM3/CM4) for product development.
• Experience with Toradex System-on-Module (SoM) platforms including Colibri, Apalis, and Verdin families, and associated carrier boards for industrial gateway/edge applications.

Linux & Shell Scripting

• Strong working knowledge of embedded Linux OS: filesystem layout, kernel interfaces, init systems (systemd), networking.
• Proficiency in Bash/Shell scripting for automation, deployment, monitoring, and diagnostics.
• Experience with Linux device driver development and device tree configuration.
• Comfortable with Linux CLI tools: gdb, strace, lsof, netstat, ifconfig/ip, systemctl, journalctl, etc.

Communication Protocols

• Industrial Protocols: Modbus RTU & TCP, RS-485/RS-232.
• IoT Protocols: MQTT (Mosquitto, Paho), HTTP/HTTPS REST APIs.
• Hardware Interfaces: SPI, I2C, UART, GPIO, USB.
• Networking: Ethernet, TCP/IP stack configuration, Wi-Fi, static/dynamic IP management.

IoT & Cloud Connectivity

• Experience developing IoT gateway applications for industrial data acquisit…
