About this role:

JET's Information Security organisation protects a technology-led, cloud-native platform serving millions of customers across multiple markets. JET's building security into the foundations of how we design, engineer, and operate our cloud-native platforms at scale, across our technology organisation. As Senior Technical Manager for Security Architecture & Engineering, you'll unite the strategic vision of Security Architecture with the hands-on execution of Security Engineering and Data Security leading a team of Security Architects, Security Engineers, and Data Security specialists. Your mandate is to define the technical north star for secure-by-design delivery, champion shift-left principles, and ensure comprehensive data protection is engineered into JET's platforms by default.

These are some of the key components to the position:

• Define and maintain JET's enterprise security architecture — leading the creation of reusable Golden Path design patterns that align with engineering standards and reduce friction for development teams across JET.
• Lead the Security Engineering function to build, test, and implement innovative security solutions fostering a culture of technical experimentation to continuously improve automation and infrastructure hardening against emerging threats.
• Own the Data Security strategy across structured and unstructured data ensuring robust engineered controls protect confidentiality, integrity, and availability of data at rest, in transit, and in use across JET's platforms.
• Direct, mentor, and grow a team of Security Architects, Security Engineers, and Data Security Engineers managing resource allocation with a strong focus on proactive NIST CSF PROTECT and IDENTIFY capabilities.
• Drive adoption of AI-aware security architecture patterns ensuring Golden Paths and engineering standards account for LLM integration risks, agentic workflows, and the secure use of MCP-connected systems across JET's development estate.
• Act as a trusted partner to Engineering Excellence, IT, and Product leadership translating architectural risk, engineering vulnerabilities, and data security trade-offs into clear business language for stakeholders.

What will you bring to the team?

• Proven track record leading a combined Security Architecture and Engineering domain within a large-scale, cloud-native organisation with clear evidence of delivering shift-left security at programme scale across multiple engineering teams.
• Deep technical expertise spanning enterprise security architecture, cloud security (AWS/GCP), secure SDLC, infrastructure hardening, and data protection with the ability to set standards that engineers can implement without unnecessary friction.
• Demonstrated experience leading broad technical teams including Architects, Engineers, and domain specialists with a track record of building capability, managing performance, and developing future leaders.
• Strong working knowledge of AI/ML security risks at the architecture and engineering layer including secure LLM integration patterns, prompt injection controls, agentic workflow security, and data exposure risks in AI pipelines.
• Strategic and pragmatic decision-maker who balances architectural rigour with business velocity able to make high-stakes technical trade-offs with incomplete information and communicate them credibly to senior leadership.
• Collaborative and influential by default a facilitatory leader who builds trust with Engineering, Product, and IT partners and drives security adoption through enablement rather than enforcement.
