Job Description   As a Security Associate Architect, you will join Thomson Reuters' Security Architecture team to embed security across our products, platforms, and enterprise systems. You will work with business and technical teams to make secure-by-design architectures and secure-by-default configurations practical, consistent, and scalable. In this role, you will provide technical leadership across the organization or within a business unit, partnering with information security and risk management, platform engineering, service management, commercial engineering and product engineering teams.

Through these activities, you will become a trusted technical advisor, build relationships across teams, mentor engineers, and improve our architecture review methods and knowledge base. You will expand your expertise across our diverse technology landscape while helping teams adopt secure solutions that protect our customers. Key Responsibilities Clarify technology risks by assessing evolving threats and technologies, and translate industry best practices, security frameworks, and applicable regulatory requirements into actionable guidance.

Establish repeatable assessment frameworks and security requirements that help teams identify risks, select controls, and demonstrate measurable outcomes through consistent governance. Work with domain architects and engineering teams to define reference architectures and secure design patterns, guide reference implementations, and support adoption across shared services and cloud landing zones to drive standardization and organizational alignment.

Assess risks, recommend controls, and document architectural decisions and trade-offs when teams need to deviate from a standard. Lead architecture reviews and threat modelling for new systems, integrations, migrations, and emerging technologies. Review multi-cloud platforms, modern application stacks, and AI and agentic systems. Track findings and help translate them into practical recommendations, align stakeholders on security trade-offs, and support through implementation.
