Job description

Who We Are

Boston Consulting Group partners with leaders in business and society to tackle their most important challenges and capture their greatest opportunities. BCG was the pioneer in business strategy when it was founded in 1963. Today, we help clients with total transformation-inspiring complex change, enabling organizations to grow, building competitive advantage, and driving bottom-line impact. To succeed, organizations must blend digital and human capabilities. Our diverse, global teams bring deep industry and functional expertise and a range of perspectives to spark change. BCG delivers solutions through leading-edge management consulting along with technology and design, corporate and digital ventures—and business purpose. We work in a uniquely collaborative model across the firm and throughout all levels of the client organization, generating results that allow our clients to thrive.

What You'll Do

• The Commercial Technology & Services portfolio underpins BCG’s revenue engine, covering the platforms that support client relationships, opportunity and proposal development, and the reuse of credentials and knowledge, so it directly shapes how quickly and effectively BCG wins and grows client work. Architecture is critical here because these capabilities depend on shared client, opportunity and engagement data moving cleanly across a SaaS-heavy, integration-dense landscape, where clear system-of-record boundaries, decoupled data and event-driven integration prevent duplication, vendor lock-in and brittle point-to-point links, and make it possible to safely connect AI agents to core commercial workflows.
• As IT Director – Enterprise Architect, you will shape the technology direction of BCG's Commercial Technology & Success (CT&S) portfolio, spanning Client Team, Marketing, Risk, Legal, ClientView, GenAI, and Knowledge platforms. These technologies support BCG's commercial activities, from client relationships and business development to knowledge sharing. You will help modernize this interconnected landscape, enabling secure, scalable, AI-powered capabilities that strengthen how BCG serves its clients.
• Working closely with technology and business leaders, you will translate enterprise strategy into architectural direction, guide critical technology decisions, and ensure solutions balance innovation, resilience, and cost efficiency. You will also champion consistent architecture practices and influence decisions across a complex, global technology environment.
• Shape portfolio architecture strategy: Assess the current technology landscape, identify risks and technical debt, and define the target architecture and prioritized, rolling three-year roadmap aligned with BCG's enterprise strategy.
• Lead architecture governance and assurance: Establish architecture standards, maintain architecture views and decision records, approve solution designs and non-functional requirements, and lead at least two Well-Architected Reviews annually.
• Enable successful technology delivery: Partner with architecture and engineering teams to resolve complex technical challenges, guide migrations, and ensure solutions meet architectural standards from design through transition to service.
• Influence technology investments: Develop architecture proposals that inform business cases, technology priorities, and funding decisions, balancing long-term value, risk, and cost.
• Advance innovation and emerging technologies: Evaluate generative AI, agentic AI, and Model Context Protocol (MCP) integrations through hands-on proofs of concept, identifying opportunities to improve efficiency, simplify integrations, and reduce technical debt.
• Strengthen technology partnerships: Collaborate with key technology vendors and internal leaders, translating product roadmaps and emerging capabilities into practical architectural improvements.
• Champion architecture leadership and collaboration: Communicate technology strategy to senior leaders, guide architecture communities, and promote consistent standards, knowledge sharing, and effective decision-making across the portfolio.

You are Good At

• Leading enterprise/solution architecture across a multi-domain portfolio — setting technical direction and holding teams accountable to a shared vision.
• Running EA governance end-to-end (Architecture Views, ADRs, ADPs, NFR sign-off, Well-Architected Reviews) as tools that speed delivery.
• Hands-on solution architecture for GenAI/agentic and MCP-based patterns, while sequencing a rolling multi-year roadmap balancing value, risk, and tech debt.
• Engaging confidently at executive level and across matrixed organizations, communicating trade-offs clearly and influencing funding decisions.
• Architecting agentic AI systems — multi-agent orchestration, tool/function-calling patterns, and MCP-based integration — with clear guardrails for autonomy, cost, and risk.
• Designing composable, headless, and event-driven architectures — API-led integration, microservices, and event streaming/message-driven patterns that decouple experience from capability.
• Architecting security and identity by design — Zero Trust principles, IAM/SSO/OAuth2/OIDC, and data protection — rather than bolting security on after the fact.
• Navigating build‑vs‑buy trade-offs across SaaS platforms and custom-built applications, integrating both into a coherent, governed architecture.

What You'll Bring

• 8+ years of enterprise or solution architecture experience, including strategy, roadmaps, and governance.
• Demonstrated ability to lead architecture decisions and guide delivery across complex technology portfolios.
• Hands‑on expertise in cloud architecture, modern engineering practices, and solution design assurance.
• Experience designing secure, scalable architectures across SaaS, APIs, integrations, and event‑driven systems.
• Knowledge of generative AI, agentic AI, and emerging technology integration patterns.
• Strong executive communication skills, with experience influencing decisions across global, cross‑functional teams.
• Ability to evaluate technology investments, guide vendor partnerships, and balance business value, risk, and cost.

Who You'll Work With

You will be a key member of BCG's central Enterprise Architecture Center of Excellence, working closely with Portfolio Leads, Technical Area Leads, Solution Architects, and Portfolio Lead Architects across CT&S. You will collaborate with global technology and business leaders to align architecture priorities, strengthen delivery, and advance BCG's enterprise technology strategy.
