Excellent communication and stakeholder management skills, with the ability to influence technical and non-technical audiences. Proven ability to lead through influence across engineering, security, operations, compliance, and customer-facing teams. Desirable Experience securing AI/ML inference platforms, model-serving infrastructure, accelerator-based systems, or confidential AI workloads. Experience with trusted execution environments, platform attestation technologies, secure firmware development, and workload identity solutions. Experience with confidential computing, secure enclaves, measured boot technologies, and remote attestation. Experience supporting highly regulated environments, critical infrastructure, or security-sensitive customer deployments. Familiarity with industry security and compliance frameworks such as SOC 2, ISO 27001, ISO 27017, ISO 27018, PCI DSS, FedRAMP, or NIST standards. Knowledge of hardware platform security, high-performance networking, storage security, and accelerator ecosystem technologies. Experience with supply-chain risk management, secure manufacturing practices, asset lifecycle controls, and secure disposal processes. Understanding of emerging cryptographic technologies and future security trends. Experience working with hyperscalers, enterprise customers, AI organisations, or managed infrastructure providers.
