Director of Software Engineering (Systems Software)

Arm is looking for a Director of Software Engineering to help lead a broad organisation spanning Systems Software (Kernel, Firmware, Power), Userspace (Performance and Enablement) and System Modelling tools.

This is a high-impact leadership role at the intersection of low-level systems software and large-scale engineering delivery. You’ll guide a distributed team of 60+ engineers (within a wider organisation of 300+), shaping software that directly influences the performance, efficiency, and scalability of Arm-based platforms!

You’ll bring together expertise across kernel, drivers, and userspace to deliver meaningful improvements in real-world systems, while collaborating across Arm and the wider open-source ecosystem.

You’ll set direction, enable teams, and drive execution across multiple domains. In practice, this includes:

• Leading and developing a globally distributed organisation of 60+ engineers
• Aligning priorities across kernel, drivers, and userspace teams
• Collaborating with architecture, hardware, and product groups to deliver co-optimised solutions
• Setting clear roadmaps that balance near-term delivery with long-term strategy
• Building strong leadership capability and supporting the growth of senior engineers
• Influencing across a complex organisation to bring teams together around shared goals

We're looking for Directors who can lead at scale while staying close to the technology, with the depth to guide direction and challenge thinking.

• Experience leading large, distributed software engineering teams (60+ engineers)
• Strong systems software background, with hands-on experience in one or more of the following:
• Linux kernel development
• Device driver development (e.g. media, graphics, or similar subsystems)
• Power and performance engineering, including system-level optimisation
• Ability to connect low-level implementation (kernel, drivers, firmware) to system-level performance, efficiency, and scalability outcomes
• Track record of delivering measurable improvements in performance, power, or system behaviour in production environments
• Experience developing high-performing teams and growing senior technical leaders
• Credibility to engage deeply with engineers across the stack and influence technical direction

• Media, graphics, or multimedia subsystem experience
• Android or userspace performance exposure
• Familiarity with Arm architecture or hardware/software co-design
• Experience working with open-source communities

This role offers the opportunity to lead across a broad and strategically critical part of Arm’s software ecosystem, influencing everything from low-level kernel behaviour to end-user performance in real-world workloads.

You’ll work in an environment that values deep technical expertise, collaborative problem-solving, and bold thinking, with the scope to make a measurable impact across billions of devices.

• Hybrid working: 2 days per week in our Cambridge office
• Clear progression path toward Senior Director level
