Staff Software Modeling Engineer

Are you excited by the opportunity to shape the future of computing by enabling developers worldwide to build software that drives innovation in IoT, cloud computing, AI, and more? Do you thrive in a role solving complex and challenging technical problems? If so, we want to hear from you!
The modeling team in Arm's Central Engineering Software (CE-SW) division enables customers across domains such as IoT, Client, and Infrastructure to develop and validate software on Arm IP-based systems.
We develop functional models of Arm Interconnect IP down to the micro-architectural level. Together with other SoC models these form Arm Virtual Platforms used to emulate complete hardware systems alongside software stacks such as Linux and Android.
These platforms enable partners to start software development earlier, accelerate validation, and perform advanced debugging and system analysis, including into low-level 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. In this role, you will:

• Develop and maintain robust, efficient C++ models of Arm's Interconnect IP for system-level simulation.
• Own technical investigations and resolve modeling and integration issues.
• Deliver models incrementally to support evolving partner requirements and enable early feedback.
• Collaborate with architects and hardware engineers to model next-generation hardware while specifications and designs are still evolving.
• Work with CE-SW engineers to integrate software on Arm Virtual Platforms, debug system-level issues, and improve modeling workflows.
• Contribute to and help drive technical discussions through clear communication, technical judgment, and collaborative problem solving.

Required Skills and Experience:

• Strong C++ development skills with proven experience building robust and efficient software.
• Good understanding of computer architecture concepts such as memory hierarchy, interconnects, and system-level behavior.
• Ability to own complex technical problems using good engineering judgment to reason through trade-offs, structure maintainable solutions, handle ambiguity, and apply appropriate software development practices.
• Strong communication and collaboration skills, including the ability to explain technical issues clearly to a range of stakeholders and work effectively across teams.

"Nice To Have" Skills and Experience:

• Experience with programmer's view modeling, instruction-level simulators (e.g. QEMU, Simics, Gem5, Virtualizer), or SoC virtual prototyping using C++, SystemC, or TLM.
• Experience with low-level software, firmware, or device-driver development.

In Return:
When joining our team, you are joining a collaborative environment where leadership is about empowering others. We embrace new and different ideas and perspectives, because we believe the best innovation only happens in a diverse and psychologically safe environment.
We support flexible working and ask our teammates to come into the office at least two days per week for planning, design discussions, and other team activities.
Salary Range:
$198,100-$268,000 per year
We value people as individuals and our dedication is to reward people competitively and equitably for the work they do and the skills and experience they bring to Arm. Salary is only one component of Arm's offering. The total reward package will be shared with candidates during the recruitment and selection process.

Hybrid Working at Arm
Arm's approach to hybrid working is designed to create a working environment that supports both high performance and personal wellbeing. We believe in bringing people together face to face to enable us to work at pace, whilst recognizing the value of flexibility. Within that framework, we empower groups/teams to determine their own hybrid working patterns, depending on the work and the team's needs. Details of what this means for each role will be shared upon application. In some cases, the flexibility we can offer is limited by local legal, regulatory, tax, or other considerations, and where this is the case, we will collaborate with you to find the best solution. Please talk to us to find out more about what this could look like for you.
