Enterprise Security Architect (City of London)

The Associates Global is seeking an experienced Enterprise Architect with a Security focus to join a large, well-established organisation undergoing major digital transformation. The company has very low staff turnover and the relatively newly stood up Architecture practice has excellent sponsorship from the top down. This is a brand-new, business-critical role, offering the chance to set the strategic direction for cybersecurity architecture at scale. This Hybrid role (2 days in) in London will require you to be an excellent communicator with natural gravitas. Your stakeholders will cut across the organisation (including SLT) as well as external providers. You will use your experience to help shape a business that is exciting and uplifting in what they do. You’ll work closely with a forward-thinking Enterprise Architecture (EA) team and collaborate with senior stakeholders across the CIO function. This is a role for someone who thrives in large-scale environments and wants to play a defining role in embedding secure-by-design principles into every stage of delivery.

The Opportunity

As the Enterprise Security Architect, you’ll own the definition and implementation of enterprise-wide security architecture. You’ll be responsible for designing strategies and frameworks that secure critical systems and services, spanning both on-premise and cloud environments. You’ll also play a hands-on leadership role in mentoring solution and technical architects, ensuring security is a foundational part of the enterprise’s long-term technology roadmap.

Key Responsibilities

• Define and lead the development of the organisation’s cybersecurity architecture strategy and roadmaps
• Translate business and technology strategies into security-focused architecture patterns
• Design and maintain conceptual and logical security architectures across multiple technology domains
• Support secure delivery of cloud and on-premise systems (Oracle, Microsoft, Salesforce, MuleSoft)
• Guide solution and technical architects on security principles, best practices, and assurance
• Contribute to architecture governance, standards, and documentation
• Partner with product, digital, data, finance, and HR teams to ensure secure system design
• Champion the adoption of emerging security technologies and practices

Skills and Experience

• Proven experience as an Enterprise or Security Architect in complex environments
• Strong understanding of enterprise security frameworks, governance, and risk management
• Experience delivering secure architectures in cloud, hybrid, and legacy systems
• Hands-on knowledge of modelling tools and frameworks (UML, ArchiMate, Bizz design ideal)
• Broad technical knowledge across infrastructure, data, CRM, HR, and finance systems
• Strong communication and stakeholder management skills across business and IT teams
• Ability to work in highly regulated or high-compliance environments
• Experience with large enterprise transformation programmes
• Exposure to architectural assurance and governance processes
• Familiarity with integrated systems and database technologies (SQL Server, Oracle, etc.)

If you are an Enterprise Architect who wants to make a real difference to an organisation's Security capability as well as work on major transformation in a business that is collaborative by nature and where you are truly valued as an individual, then this is definitely a role worth considering. Having worked with this business for a number of years and placing people across the organisation it is very evident that their culture is brilliant. Their work environment is demanding insofar as taking on technical challenges and requiring people to deliver collaboratively and they celebrate their wins as a team rather than a promotion race.
