Staff Software Security Engineer

We are looking for a hands-on Firmware & Operating Systems Hardware Security Engineer to support the security of SoC hardware platforms. This role is part of the Arm Product Security team and focuses on identifying problems in silicon level security features, understanding their impact, and working in partnership with architecture and silicon teams to help improve the overall security of our platforms.

In this role, you will chip in through detailed technical analysis, proof-of-concept demonstrations, and tooling that supports the assessment and improvement of hardware security features across sophisticated SoC platforms. You will work in a team that values collaboration, learning, and thoughtful problem-solving., * Carry out hands-on security assessments of SoC hardware components and security features, including trust anchors, debug interfaces, and isolation mechanisms

• Identify and analyse hardware security issues using approaches such as architecture review, hardware interface analysis, and experimental testing
• Develop proof-of-concept demonstrations that illustrate realistic system-level impact of hardware weaknesses
• Apply and grow knowledge of hardware security techniques relevant to silicon security, privilege boundaries, and trust architectures
• Develop and maintain tools and methodologies that support hardware security evaluation and experimentation
• Collaborate closely with architecture, silicon design, firmware, and platform teams to clearly communicate findings and support effective mitigations

Do you have experience in Security analysis?, * Practical experience in offensive security, vulnerability research, or low-level systems security

• Deep knowledge in microarchitecture and SoC design principles
• Experience reviewing architectural specifications and RTL for security-relevant behaviour
• Strong understanding of modern SoC architectures, including security boundaries, privilege levels, and hardware isolation mechanisms
• Experience analysing hardware interfaces and platform components such as debug infrastructure, secure boot root of trust, or system interconnects
• Familiarity with hardware debug interfaces (e.g., JTAG, SWD) and relevant hardware attack techniques
• Experience working with low-level programming languages such as C, with working knowledge of assembly language (preferably Arm)
• Understanding of hardware-software interactions and how security properties are enforced across system layers
• Ability to write clear, well-structured technical reports and document security findings
• Ability to work both independently and collaboratively within a diverse, inclusive team

“Nice To Have” Skills and Experience :

• Experience with Arm-based platforms and SoC security architectures
• Familiarity with hardware security analysis techniques such as fault injection and side-channel analysis
• Experience using laboratory equipment and tooling for hardware experimentation and debugging
• Exposure to silicon bring-up environments or hardware validation workflows
• Contributions to internal or external hardware security research, tools, or vulnerability disclosures

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.
