DXC Technology

Role Overview

DXC Technology is seeking a Lead Cybersecurity Architect & Engineering Lead to own the integrated cybersecurity architecture for a major greenfield enterprise transformation programme.

Working under the programme Design Authority, you will lead security design across segregated, air-gapped and cross-domain environments. You will coordinate specialist engineering teams across identity, cryptography, security operations, endpoint, data, application and OT/IoT security, ensuring a coherent architecture from design through implementation, testing and operational transition.

The role combines architecture ownership, technical direction and engineering governance, supported by domain specialists, OEM architects and delivery partners.

Key Responsibilities

Cybersecurity Architecture & Design Authority

• Develop and maintain the integrated Cybersecurity High-Level Design (HLD).
• Lead and govern capability-specific Low-Level Designs (LLDs) produced by engineers, OEMs and domain specialists.
• Define security principles, standards, architecture patterns and secure-by-design requirements.
• Design security controls for segregated, air-gapped and cross-domain environments.
• Maintain traceability between requirements, designs, implementation decisions and the Bill of Quantities (BoQ).
• Lead architecture reviews and support Design Authority approvals.
• Align designs with applicable security, privacy and regulatory requirements.

Security Capability Integration

• Lead architecture across IAM, PAM, PKI, cryptography, security operations, endpoint protection, data protection and application security.
• Define the monitoring, detection, response and automation architecture across SIEM, SOAR, SOC and related capabilities.
• Govern specialist development of detection content, response playbooks and security integrations.
• Define secure integration requirements across applications, infrastructure and cybersecurity platforms.
• Coordinate with network, infrastructure, applications, smart-campus and service-management workstreams.
• Integrate OT/IoT security, resilience and cyber recovery requirements into the overall design.
• Provide technical direction to multidisciplinary cybersecurity engineers and domain specialists.
• Review detailed designs, configurations and implementation approaches against the approved architecture.
• Coordinate OEM and vendor inputs and resolve cross-platform technical issues.
• Challenge design proposals constructively and manage technical decisions, risks and dependencies.
• Validate platform sizing, licensing, support requirements and BoQ quantities.
• Identify opportunities to optimise solutions while maintaining security and operational requirements.

Testing, Go-Live & Operational Transition

• Define cybersecurity testing, acceptance criteria and assurance requirements.
• Coordinate validation activities across engineering, application and OEM teams.
• Review material security findings, design deviations and remediation proposals.
• Support go-live readiness, operational handover and transition to support teams.
• Provide security recommendations for interim and transitional application environments.
• Communicate progress, risks, dependencies and required decisions to programme stakeholders.

Required Qualifications & Experience

• Bachelor’s degree in Cybersecurity, Information Security, Computer Science, Engineering or a related discipline, or equivalent professional experience.
• At least 12 years of relevant cybersecurity experience.
• At least 5 years leading security architecture or engineering activities for complex enterprise, government, defence or critical-infrastructure programmes.
• Demonstrated experience coordinating multidisciplinary cybersecurity teams, OEMs and vendors.
• Strong experience producing HLDs and governing detailed security designs.
• Experience architecting segregated, air-gapped or cross-domain environments.
• Experience with cybersecurity solution sizing, licensing and BoQ development.
• Strong technical writing, stakeholder management, analytical and problem-solving skills.
