Mizuho • New York, NY

2d • $160,000 - $250,000 • Hybrid

About The Position

Join Mizuho as a Enterprise Architecture Operations Lead! In this role, you will partner across technology and the business to strengthen architecture governance and improve transparency across Mizuho’s application and technology landscape. In this hands-on role, you will own key portfolio management capabilities—including technical debt tracking, application-to-capability mapping, standards and tech stack adherence, and future-state landscape roadmaps—while producing actionable insights on risk, lifecycle, duplication, and modernization opportunities. The ideal candidate will also lead the definition of the technical and financial inputs required to model Total Cost of Ownership (TCO), enabling consistent cost transparency and better-informed investment decisions.

Requirements

• At least 7+ years of experience in enterprise architecture, technology portfolio management (TPM), or a closely related discipline, with hands-on ownership of application/technology inventories, lifecycle management, and portfolio analytics.
• Prior experience in the financial industry (e.g., bank, broker-dealer, asset manager, or fintech) is required.
• Ability to operate effectively in a regulated financial services environment, with working knowledge of technology risk, audit, and control expectations (e.g., policy/standard compliance, exception handling, documentation discipline).
• Strong understanding of modern enterprise technology stacks (cloud/hybrid infrastructure, middleware, data platforms, integration patterns, and security fundamentals) and how standards and reference architectures drive reuse, resilience, and simplification.
• Experience with portfolio and architecture repositories and ITSM/CMDB tooling (e.g., LeanIX, ServiceNow, Apptio/TBM, Planview, Alfabet, or similar), including data quality management, governance workflows, and reporting.
• Proficiency in data analysis and visualization (e.g., Excel, SQL, Power BI/Tableau) to build and maintain portfolio dashboards, KPIs, and executive reporting on health, risk, lifecycle, duplication, vendor exposure, and modernization outcomes.
• Proven ability to partner with application owners, engineering leads, infrastructure, security, and finance to drive outcomes through influence—facilitating standards adoption, managing exceptions, and aligning remediation and roadmap decisions to business priorities.
• Strong documentation and process design skills, including defining operating procedures for portfolio intake/updates, data stewardship, controls evidence, and continuous improvement of taxonomies, scoring models, and governance cadences.
• Eligibility to work in the local market
• Bachelor’s degree in Computer Science, Information Systems, Engineering, or equivalent practical experience
• Demonstrated ability to define and enforce architecture standards, create target-state roadmaps, model Total Cost of Ownership (TCO), and communicate portfolio insights through clear dashboards and executive-ready narratives.

Nice To Haves

• advanced degree and/or relevant certifications (e.g., TOGAF, BIAN, ITIL, FinOps, TBM) are a plus.

Responsibilities

• Maintain, record, and proactively manage technical debt across Mizuho’s application portfolio by establishing governance, defining taxonomies and scoring criteria, capturing remediation plans, and reporting progress, risk, and trends to technology and business stakeholders.
• Capture, maintain, and continuously improve the enterprise application portfolio inventory, including ownership, lifecycle status, integrations, and key non-functional attributes, and map each application to the business capabilities and processes it enables to support rationalization and investment decisions.
• Track adherence to the approved technology stack, architecture blueprints, and engineering standards by monitoring reuse and exceptions, identifying duplication, and partnering with delivery teams to increase standard adoption and reduce cost, complexity, and operational risk.
• Maintain the future-state technology landscape by developing and updating target architecture views, transition roadmaps, and dependency mappings that reflect strategic direction, modernization priorities, and decommissioning timelines.
• Perform technology portfolio management and analysis by consolidating data across applications, platforms, and services; producing dashboards and insights (e.g., health, risk, lifecycle, vendor exposure, and modernization opportunities); and recommending actions to optimize spend and resilience.
• Guide and lead the definition of technical requirements and data inputs needed to model Total Cost of Ownership (TCO), including infrastructure, licensing, support, run/change costs, resiliency/DR, and end-of-life impacts, to enable consistent cost transparency and evidence-based decision-making.
