What You'll Do

BCG is looking for a Senior Director level Enterprise Architect to pioneer the modernisation of our Identity and Network architecture, securing access and connectivity for BCGers and clients across the globe, 24x7, 365 days of the year.

The heart of this role is to define the architecture of identity, access, and network connectivity that underpins secure, seamless digital experiences for our employees and clients. You will be an expert in identity and access management and zero trust network architecture. You will have considerable experience designing scaled, secure identity and network platforms for a global company.

You’ll bring teams together to leverage the scale of BCG by defining a shared, identity-first architecture direction and the guardrails to get there. Driving a modern, zero trust approach to identity and network, you’ll play a leading role in the transformation of BCG IT.

What You'll Bring

• 10+ years’ experience leading and owning the enterprise architecture of identity and network estates at global scale. This includes managing the value, opportunities, inventory, roadmaps, rationalisation, and total cost of ownership for identity and network platforms
• Your experience will include multiple successful examples of autonomously:planning a global identity and network estate across requirements, technology, cost, value and rationalisation
• leading and agreeing investment decisions at a portfolio and individual technology level
• leading the development of architectures across identity and access management (e.g. Microsoft Entra ID, Okta, privileged access management, identity governance and administration) and zero trust network access (e.g. SASE, SSE, ZTNA, SD-WAN). You must have deep, hands‑on experience with at least one major identity platform (Entra ID, Okta or Ping) and at least one SASE/SSE platform (e.g. Zscaler, Palo Alto Prisma).
• leading decisions through to a conclusion in a highly matrixed organisation with minimal or no supervision.
• Preparing materials for, and presenting at, senior levels including C-Suite

Who You’ll Work With

This is an individual contributor role with an expectation of strongly influencing architects working across the Identity and Network domains.

Additional info

At BCG, our people and relationships are at the heart of everything we do. We believe that in‑person collaboration plays an important role in our culture, mentorship, and professional development.

For this role, you will generally be expected to work from a BCG office or in person with clients on a regular basis (typically around 50% of working time), depending on business needs and in line with local policies and practices.

We aim to provide a dynamic and collaborative environment that fosters connection and teamwork.

You’re Good at:

• Energising our people to set a vision and see the possibilities of modern identity and network technologies, i.e. zero trust network access, cloud‑native identity platforms, identity governance, and secure, context‑aware connectivity.
• Finding great answers to complex and ambiguous questions, and connecting and collaborating across teams to develop their architectures, especially to meet demanding non‑functional requirements. You will seek diverse views, and with a growth mindset considering both conventional and unconventional answers.
• Rolling up your sleeves and “doing”, pioneering the way forward and bring others along with you. You produce high‑quality Enterprise Architecture arguments and supporting materials. You are adept at agreeing these at different levels in the organisation. You must be a brilliant storyteller.
• Influencing and collaborating with others, especially solution architects and technical leaders across the organisation. You will be passionate at developing others through mentoring, coaching, and sharing knowledge.
• You will be enthused by technology. Knowledgeable and conversant with modern identity and network paradigms, and always curious and driven to learn more and apply this to your work. You will demonstrate expertise in zero trust architecture, identity governance and administration (IGA), privileged access management, SASE/SSE, and cloud‑native directory and authentication services.
• Optimising your own role and delivering results. You understand that architecture is part of a value stream where we need to play our part in being efficient to help increase velocity and reduce risk across the architecture team and the teams we work with.
