Embedded Firmware Engineer (3–8 Years Experience)

Firmware for VitalMed’s embedded and automation products: from low-level drivers to real-time applications.

Location : Pollachi, Tamil Nadu

Language : Good English (written and spoken)

Position Overview

We are looking for an experienced Embedded Firmware Engineer (3–8 years) who can develop robust, scalable, and efficient firmware for microcontroller- and microprocessor-based systems. The ideal candidate should have strong expertise in embedded C/C++, communication protocols (CAN, SPI, I2C, UART, SDIO), board bring-up, debugging, and real-time systems. Experience with Embedded Linux development is a strong plus.

Key Responsibilities

1. Firmware Development

• Develop, optimize, and maintain embedded firmware in C/C++.
• Implement low-level drivers, middleware, and application logic for MCUs and MPUs.
• Work on boot sequences, peripheral initialization, interrupt handling, and real-time tasks.

2. Communication Protocols

• Develop, test, and troubleshoot communication interfaces including CAN / CAN-FD, SPI, I2C, UART, and SDIO.
• Integrate external sensors, memories, displays, and modules using these protocols.
• Work with higher-level communication stacks if required.

3. MCU & MPU Experience

• Perform board bring-up, including bootloader programming, memory configurations, and peripheral drivers.
• Work with microcontroller families such as STM32, NXP, TI, Renesas, Microchip, ESP32, Nordic, etc.
• Work with microprocessors (ARM Cortex-A series, i.MX, AM335x, etc.) for advanced applications.

4. Real-Time Systems & Optimization

• Implement RTOS-based designs (FreeRTOS, Zephyr, ThreadX, etc.).
• Optimize CPU usage, memory footprint, timing, and power consumption.
• Ensure reliable real-time performance and deterministic behavior.

5. Debugging & Testing

• Debug complex firmware/hardware issues using JTAG/SWD, logic analyzers, oscilloscopes, and serial tools.
• Write unit tests, integration tests, and support validation of embedded features.
• Analyze logs, traces, and performance metrics.

6. Embedded Linux (Preferred but Not Mandatory)

• Experience with Linux kernel drivers, device tree configuration, or Yocto/Buildroot systems is a plus.
• Work with middleware, services, and hardware abstraction layers in Linux-based systems.

7. Collaboration & Documentation

• Collaborate closely with hardware, QA, and product teams for system-level integration.
• Participate in code reviews and follow best coding practices.
• Prepare documentation—API docs, design summaries, test reports, and release notes.

Required Qualifications & Skills

• Bachelor’s/Master’s degree in Electronics, Electrical, Computer Engineering, or related field.
• 3–8 years of hands-on experience in embedded firmware development.
• Strong knowledge of Embedded C/C++, microcontrollers, and real-time concepts.
• Experience with CAN, SPI, I2C, UART, SDIO protocols.
• Experience with at least one major microcontroller family (STM32, NXP, TI, ESP32, Microchip, etc.).
• Strong debugging skills and hands-on experience with lab equipment.
• Understanding of firmware architecture, memory management, and low-level hardware interfaces.

Preferred Skills

• Embedded Linux driver development, device tree, U-Boot, Yocto/Buildroot.
• Experience with FreeRTOS or other real-time operating systems.
• Experience with OTA updates, secure boot, or communication stacks (MQTT, BLE, TCP/IP).
• Familiarity with version control (Git) and CI/CD workflows.

Soft Skills

• Strong analytical and problem-solving skills.
• Good communication and documentation ability.
• Ability to work independently and mentor junior engineers.
• Ownership mindset and strong attention to detail
