About The Position

As organizations undertake large-scale digital transformation, cloud migration, and technology modernization initiatives, the need for robust, scalable security architecture has never been greater. Security architecture decisions made today define an organization's risk posture for years to come—shaping how data is protected, how systems are connected, and how threats are detected and contained. As a Senior Consultant within EY's Cyber practice focused on Enterprise Security Architecture, you will work with clients to assess existing security architectures, design future-state security frameworks, and develop practical roadmaps that align security capabilities with enterprise strategy. This role offers the opportunity to engage in technically hands-on architecture work alongside strategic advisory engagements across diverse industries.

Strong understanding of enterprise security architecture principles, patterns, and frameworks, with the ability to design solutions across network, cloud, application, data, identity, and endpoint security domains.
Hands-on experience conducting security architecture assessments, threat modeling, and architecture risk analysis across complex enterprise environments.
Ability to design and document security reference architectures, technology blueprints, and security patterns that align to business objectives and risk appetite.
Experience applying Zero Trust architecture principles and translating them into practical, implementable security designs.
Knowledge of cloud security architecture across major cloud platforms (AWS, Azure, GCP), including hybrid and multi-cloud environments.
Familiarity with enterprise architecture frameworks such as SABSA, TOGAF, or Zachman as applied to security architecture engagements.
Strong critical thinking, analytical, and problem-solving skills applied to complex security architecture challenges.
Ability to communicate technical architecture concepts effectively to both engineering teams and executive stakeholders.
Experience developing architecture documentation, executive presentations, and client-facing deliverables.
Strong verbal and written communication skills.
Ability to manage competing priorities in a fast-paced consulting environment.
Strong attention to detail and commitment to high-quality client service.
Ability to build relationships and collaborate effectively across multidisciplinary teams and client organizations.

A bachelor's degree in Cybersecurity, Computer Science, Information Systems, Engineering, or a related field, and approximately 3–5 years of relevant experience; or a graduate degree and 2–4 years of relevant experience.
Experience in enterprise security architecture assessments and future-state architecture design
Experience in network security architecture, including segmentation, secure access, and perimeter design
Experience in cloud security architecture across AWS, Azure, or GCP, including IaaS, PaaS, and SaaS security
Experience in identity and access management architecture, including Zero Trust and privileged access design
Experience in application security architecture, secure SDLC, and DevSecOps integration
Experience in data protection architecture, including encryption, data classification, and data loss prevention
Experience in security architecture governance, standards development, and architecture review processes
Knowledge of cybersecurity frameworks and standards, including NIST CSF, NIST 800-53, ISO 27001/27002, CIS Controls, and SABSA.
Experience conducting security architecture reviews, threat modeling, and risk assessments in complex enterprise environments.
