Key Responsibilities

  • Establish and evolve firmware architecture for complex embedded platforms, ensuring scalability, security, and long-term maintainability.
  • Lead technical reviews and mentor engineering teams to uphold coding standards, design patterns, and best practices.
  • Collaborate across hardware, software, and systems engineering disciplines to refine product performance and reliability.
  • Perform board bring-up, validate MCU peripherals, and develop low-level drivers for embedded controllers.
  • Design and implement real-time, multi-threaded applications on ARM-based microcontrollers using C and C++.
  • Build and maintain automated test frameworks, diagnostic tools, and internal software to support development and validation.
  • Ensure traceability of requirements, manage software dependencies, and maintain comprehensive technical documentation.
  • Advance capabilities in wireless connectivity, power efficiency, and embedded security across product platforms.
  • Implement and optimize CI/CD pipelines and DevOps practices tailored to embedded firmware workflows.
  • Diagnose and resolve deep-level hardware-firmware interaction issues, providing root cause analysis and corrective solutions.
  • Ensure designs meet safety, regulatory, and industry compliance standards for embedded systems.

Qualifications

Candidates must have a Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or Computer Engineering, along with at least 10 years of professional firmware development experience focused on embedded systems.

  • Proficiency in C and C++ with strong understanding of object-oriented design and embedded programming patterns.
  • Proven experience with real-time operating systems (RTOS), including task scheduling, resource management, and interrupt handling.
  • Hands-on knowledge of embedded communication protocols such as CAN, SPI, and I²C.
  • Familiarity with Bluetooth, wireless technologies, and display interfaces including LCD and OLED.
  • Experience developing and debugging firmware directly on ARM-based hardware platforms.
  • Solid background in software configuration management, peer review processes, and defect tracking systems.
  • Working knowledge of CI/CD pipelines and DevOps tools in embedded environments.
  • Experience managing dependencies and build systems in large-scale firmware projects.

Preferred Background

  • Experience with Linux or RTOS in embedded contexts.
  • Scripting ability in Python or Bash for automation and tooling.
  • Exposure to IoT systems and cloud-connected device architectures.
