Embedded Engineer

Key Responsibilities:

• Design, develop, and debug embedded firmware (bare-metal and RTOS-based) for ARM Cortex-M4 (32-bit / 64 Bit) controller platforms.
• Perform board bring-up activities including peripheral initialization, clock configuration, and low-level device driver development.
• Develop and maintain device drivers for on-chip and external peripherals, ensuring robust hardware-software integration.
• Implement and troubleshoot communication interfaces such as UART, SPI, I2C, RS-232, and RS-485.
• Develop and integrate industrial communication protocols including CAN Bus, Modbus-RTU / TCP, HTTP, TCP/IP, and Ethernet-APL.
• Work on Linux-based backend systems for process automation and system-level diagnostics; write and maintain shell scripts for build, deployment, and automation workflows.
• Debug and validate firmware using JTAG, SWD, oscilloscopes, logic analyzers, and Wireshark; perform static code analysis using PC-Lint.
• Follow structured SDLC practices (V-model) and contribute to development in compliance with IEC 61508 (functional safety) and IEC 62443-4-1 (industrial cybersecurity) standards.
• Conduct protocol conformance testing to ensure interoperability and adherence to industrial communication standards.
• Use IAR Embedded Workbench for firmware development, debugging, and optimization.
• Manage source code using Git and collaborate on CI/CD pipelines and work tracking via Azure DevOps.
• Collaborate with cross-functional teams (hardware, QA, systems engineering) to troubleshoot integration issues and ensure product reliability.
• Prepare and maintain technical documentation, design specifications, and test reports in accordance with SDLC requirements.
