Senior Software Engineer

Job ID 2025-15684 Date posted Sep. 12, 2025 Location Waltham, Massachusetts Category Software Engineering Apply

The modelling team in Arm's Central Engineering Software (CE-SW) division enables customers across domains (e.g., IoT, Client, Infrastructure) to build and validate software on Arm IP-based systems. We create highly efficient models of Arm Interconnect IP down to the micro-architectural level, which, together with other SoC models, form Arm Virtual Platforms. These platforms emulate complete hardware systems alongside sophisticated software stacks (e.g., Linux, Android), enabling partners to start software development earlier, accelerate execution, and perform advanced debugging such as inspecting memory bus transactions.

Responsibilities:

The Interconnect Fast Model team transforms hardware specifications into high-performance software models that power early software development and system validation.

· Develop, test, and maintain robust, efficient C++ models of Arm’s Interconnect IP for use in system-level simulation.

· Deliver models in iterative increments that meet evolving partner requirements and enable early feedback.

· Collaborate with architects and hardware engineers to understand next-generation hardware designs while they are still in development.

· Work with CE-SW engineers to integrate software on Arm’s Virtual Platform and diagnose issues.

· Foster open idea-sharing and constructive challenge within the team to drive better technical and collaborative outcomes.

Required Skills and Experience:

· Strong understanding of C++ and proven experience developing robust, efficient software, with solid skills in coding, testing, and debugging.

· Good understanding of computer architecture, with the ability to apply concepts such as memory hierarchy, coherency, and interconnect design.

· Proven track record or strong interest in driving efficiency and continuous improvement, with a focus on empowering individuals, strengthening team processes, and enabling collective success.

· Strong communication and collaboration skills to build consensus, share knowledge, and further a constructive team culture.

“Nice To Have” Skills / Experience:

· Experience with programmer’s view modeling, instruction-level simulators (e.g., QEMU, Simics, Gem5, Virtualizer), or SoC virtual prototyping using C/C++/SystemC/TLM.

· Experience with low-level or bare-metal software, firmware or device-driver development.

· Creative problem solving and innovative approaches to complex challenges.

In Return

When you join our team, you are joining a collaborative group that embraces different ideas and perspectives, because we believe that the best innovation only happens in a diverse and psychologically safe environment. We work closely with other software, hardware and system teams across the company. You will have a chance to share ideas with and learn new skills from the best engineers in the world.
