Job description

Arm is looking for a Senior Firmware Developer to help build the software stack for next-generation compute subsystems in software-defined, intelligent vehicles. You will collaborate closely with technical leads and architects across our engineering domains to enable partners and customers to fully demonstrate the capabilities of our platforms.

This is a hands-on individual contributor role, placing significant emphasis on actively crafting, writing, debugging and reviewing production-quality code. We are looking for engineers who remain deeply engaged in low-level development and take ownership of delivering robust, high-quality implementations.

We are particularly interested in individuals with broad exposure to system software at the firmware level, spanning compute, vision, AI, and safety/security subsystems.

If you are passionate about working at the intersection of pioneering hardware and system software, we would love to hear from you.

Responsibilities:

• Hands-on design, implementation, debugging and integration of our software stack, with a strong focus on writing high-quality, production-grade code
• Building the core firmware and device drivers for our automotive compute subsystems.
• Write, review and maintain robust, efficient C/assembly/Yocto code across firmware and low-level system components.
• Analyze and optimize CPU, GPU, I/O, and memory usage across system components.
• Help plan and prioritize engineering work packages in coordination with project management and tech leadership.
• Mentor other engineers and uphold high code quality and maintainability standards.

Required Skills and Experience :

• Bachelor’s or Master’s Degree or equivalent experience in Computer Science, Electrical Engineering, or a related field.

• Strong skills in C and Assembly with deep expertise in low-level compute infrastructures.
• Demonstrated track record of actively supplying code in recent roles (e.g., core features, drivers, or low-level system components).
• Knowledge in Arm architectures as well as the Arm Trusted Firmware is highly preferred.

“Nice To Have” Skills and Experience :

• Practical experience with additional system programming languages, such as C++ or Rust.
• Fluency in scripting languages such as Python and/or Bash.
• Zephyr RTOS or Free/SafeRTOS development.
