Product & Technology is responsible for establishing unified standards and governance practices throughout the company. Additionally, we oversee the development and maintenance of core applications essential for the seamless operation of various functions across the organization. We are committed to driving and executing future roadmaps that are in line with the overall strategic direction of RWS.\nWith a global reach, Product & Technology provides support services to over 7500 end users worldwide. We take pride in managing the information security operation and safeguarding all our assets. Our core functions encompass Enterprise & Technical Architecture, Network & Voice, Infrastructure, Service Delivery, Service Operations, Data & Analytics, Security & Quality Compliance, Transformation, Application Development, Enterprise Platforms, With a dedicated team of over 500 staff, Product & Technology ensures a strong presence across all regions, enabling efficient and effective support to our global operations.\nJob Overview\nKey Responsibilities\nSecurity Engineering Leadership\nLead and develop the Security Engineering team, providing clear technical direction, priorities and accountability.\nCoach and mentor Security Engineers and Senior Security Engineers, building both technical depth and engineering leadership capability.\nEstablish engineering principles, standards and ways of working for the Security Engineering function.\nOwn and prioritise the Security Engineering backlog and ensure engineering effort is focused on the areas of greatest organisational risk and value.\nBuild a culture of engineering excellence, automation, ownership, collaboration and continuous improvement.\nRemain technically engaged and provide senior-level guidance on complex security engineering challenges.\nSecurity Architecture & Engineering\nLead the development of reusable security architectures, patterns and technical guardrails.\nProvide technical leadership for security architecture and secure design decisions.\nLead or support threat modelling and technical security reviews for significant platforms, products and services.\nEstablish secure-by-design and secure-by-default approaches that can be consistently adopted across Product & Technology.\nLead the Security Engineering contribution to architecture governance and design assurance.\nSecurity Platforms\nOwn the technical strategy and engineering lifecycle for strategic security platforms.\nDrive consolidation of fragmented or overlapping security technologies.\nEnsure platforms are integrated into a coherent enterprise security ecosystem.\nEstablish appropriate engineering standards for deployment, configuration, integration and lifecycle management.\nDrive platform optimisation, resilience, coverage and adoption.\nEstablish clear handovers and operational models with Security Operations.\nCloud Security Engineering\nLead security engineering across AWS, Azure, SaaS and cloud-native environments.\nEstablish cloud security architecture, baselines, guardrails and reusable patterns.\nLead adoption and optimisation of CSPM and cloud workload security capabilities.\nEmbed security into cloud landing zones and platform engineering practices.\nEstablish scalable controls for containers, Kubernetes, serverless and modern cloud workloads.\nPartner with cloud and platform teams to resolve systemic security weaknesses rather than addressing individual findings in isolation.\nDevSecOps & Secure Software Delivery\nDefine and lead the Security Engineering approach to DevSecOps and secure software delivery.\nEmbed automated security controls within CI/CD and engineering workflows.\nLead adoption and optimisation of SAST, DAST, SCA, secrets scanning and related application-security capabilities.\nEstablish reusable security configurations, workflows and engineering patterns.\nPartner with engineering leadership to improve secure development practices without introducing unnecessary delivery friction.\nChampion security-as-code and policy-as-code approaches.\nSecurity Automation\nEstablish an automation-first approach across Security Engineering.\nIdentify high-volume manual processes that can be replaced with engineering and automation.\nDrive integration between security platforms through APIs, orchestration and event-driven workflows.\nPromote Infrastructure as Code and policy-as-code.\nDevelop reusable automation capabilities that can be consumed across Security, Engineering and Platform teams.\nMeasure automation effectiveness and continually identify opportunities to reduce manual effort.\nIdentity & Zero Trust Engineering\nProvide technical leadership for security engineering requirements relating to identity and privileged access.\nSupport the development of automated identity controls and access governance integrations.\nDrive adoption of Zero Trust and identity-centric security principles.\nPartner with the relevant enterprise technology teams on PAM, Conditional Access and privileged identity improvements.\nEnsure identity controls integrate effectively with cloud, endpoint and security monitoring capabilities.\nAI Security Engineering\nEstablish practical technical security controls and guardrails for AI-enabled platforms and solutions.\nPartner with AI, Product, Engineering, Data and SGRC teams to translate AI security and governance requirements into technical controls.\nSupport secure architecture and threat modelling for AI solutions.\nDevelop reusable patterns that enable secure AI adoption rather than relying solely on manual assurance.\nTechnical AI security controls are explicitly assigned to Security Engineering within the current operating model, while AI governance is led through SGRC with Security Engineering responsible for technical implementation.\nSecurity Operations Partnership\nEstablish effective engineering-to-operations handovers for new security capabilities.\nPartner with Security Operations to improve monitoring, detection and response capabilities.\nProvide engineering expertise during complex security incidents where required.\nEnsure lessons identified through incidents are translated into sustainable technical improvements.\nPartner on vulnerability prioritisation and remediation, focusing particularly on systemic and repeatable engineering solutions.\nStakeholder & Cross-Functional Leadership\nBuild strong relationships with Software Engineering, Platform Engineering, Enterprise Architecture, IT, Product, Data & AI, Security Operations and SGRC.\nTranslate complex security challenges into pragmatic technical solutions.\nInfluence engineering roadmaps and architecture decisions.\nRepresent Security Engineering within technical and architecture governance forums.\nCommunicate technical risks, priorities and investment requirements clearly to senior technology and security leadership.\nSkills & Experience\nEssential\nSignificant experience in Security Engineering, Cloud Security, Platform Engineering, DevSecOps or related engineering disciplines.\nProven experience leading engineers or providing technical leadership across complex engineering environments.\nDeep understanding of security architecture and security control design.\nStrong experience securing AWS and/or Azure environments.\nStrong understanding of cloud-native architecture, containers and modern infrastructure.\nProven experience integrating security
