Join the team shaping the future of secure computing.

Arm’s hardware powers the AI, computing, and connectivity revolution that continues to transform how people live, work, and connect.

As part of our growth, we’re looking for a skilled and motivated Security Verification Engineer to join our CPU Cambridge team. You’ll collaborate with colleagues around the world on next‑generation CPU IP products, helping ensure they meet the highest standards of security and reliability.

We welcome applications from engineers at various stages of their careers, from those building their expertise to those ready to take on broader technical responsibilities. If you thrive in a creative, multidisciplinary, multicultural environment and want to make a meaningful impact on the future of technology, we’d love to hear from you.

• Collaborate with security architects, leads, and verification engineers to identify and analyze potential vulnerabilities in Arm’s CPU IP.
• Plan and implement security verification activities across the product lifecycle, using techniques such as static and dynamic analysis, fuzzing, and side‑channel testing.
• Design targeted tests based on threat models, design reviews, and risk assessments.
• Apply advanced verification methods including tainted‑data tracking and symbolic execution to uncover dataflow and integrity issues.
• Use industry‑leading tools for formal analysis, vulnerability discovery, penetration testing, and automated verification.
• Develop and maintain reusable verification infrastructure at both IP and system levels.
• Work with product managers and project/security leads to align on security goals, project milestones, and deliverables.

• Hold a university or Engineering School degree. This can be a Bachelor’s, Master’s or PhD in Computer Science, Mathematics, Electronic / Electrical Engineering or Physics. Candidates with alternative degrees will also be considered if they have relevant experience.
• Background in hardware/software development and verification (System‑Verilog, UVM, C/C++, Python).
• Hands‑on experience with security verification methods such as fuzzing, static analysis, formal verification, or symbolic execution.
• Experience in threat modelling, vulnerability analysis and secure architecture reviews.
• Understanding of dataflow analysis, tainted‑data tracking or side‑channel mitigation techniques.
• Strong communication, technical writing and collaboration skills.

• Experience with Secure Boot, hardware roots of trust, cryptographic primitives, and secure communication protocols.
• Knowledge of secure development lifecycle (SDL) processes and tooling.
• Contribution to open‑source security tools or frameworks.
• Familiarity with security standards and frameworks, particularly ISO/SAE 21434, NIST SP 800-53, or ISO 27001.
