Senior Embedded Software Engineer

Location: Hyderabad, Telangana, India

Role Overview

Azimuth AI is seeking a highly skilled Senior Embedded Software Engineer to join our Hyderabad engineering team. The team is responsible for the design and development of next-generation embedded platforms, including MCU drivers, RTOS integration, RF communication stacks, radio APIs, FOTA (Firmware Over-The-Air) solutions, embedded security features, and system-level firmware components.

The ideal candidate will have 10–15 years of hands-on embedded software development experience with strong expertise in C/C++, ARM-based microcontrollers, RTOS, wireless communication protocols, and firmware architecture. This role requires a strong technical leader who can drive firmware development from concept through production while collaborating closely with hardware, validation, product, and customer teams.

Key Responsibilities

  • Design, develop, and maintain embedded firmware and software modules for MCU-based platforms.
  • Lead the development of peripheral drivers, middleware, and platform services.
  • Design and implement secure FOTA/OTA update mechanisms, including bootloaders, image validation, rollback, fail-safe recovery, and firmware lifecycle management.
  • Architect scalable, reusable, and maintainable embedded software solutions.
  • Develop, integrate, and optimize RF communication stacks and wireless protocols.
  • Work closely with hardware, RF, and system teams to debug and optimize wireless performance.
  • Analyze protocol-level issues and drive interoperability testing across multiple device ecosystems.
  • Develop and maintain embedded security features including secure boot, firmware authentication, encryption, and key management.
  • Optimize software for performance, memory footprint, power consumption, and reliability in resource-constrained environments.
  • Troubleshoot and resolve complex system-level issues involving hardware, firmware, RTOS, and wireless communication.
  • Conduct design reviews, code reviews, and ensure adherence to software quality standards and best practices.
  • Mentor engineers and provide technical leadership across firmware projects.
  • Collaborate with customers and internal stakeholders to enable product use cases and resolve technical challenges.
  • Drive software quality initiatives through unit testing, automation, continuous integration, and release processes.
