Job Summary

U.S. Bank is seeking a highly experienced technology leader to serve as the Director of Architecture for a critical card processing platform supporting Consumer and Small Business customers in a highly regulated, always-on environment.

This role leads the architecture function, overseeing a team of architects responsible for designing and guiding complex payment solutions across a hybrid technology landscape. The Director will drive architecture strategy, solution design, and feasibility decisions across new product initiatives and business opportunities.

This is a technical leadership role, focused on architecture design and decision-making-not engineering execution-requiring strong expertise across mainframe and modern technology stacks (distributed systems, cloud, APIs, and microservices).

What You'll Do

Architecture Leadership

• Lead and develop a team of architects responsible for end-to-end architecture across ICS initiatives
• Establish architectural direction across mainframe, API, distributed systems, and cloud environments
• Drive consistency, quality, scalability, and governance in architecture practices

Solution Design & Feasibility

• Oversee high-level solution design, feasibility assessments, and effort sizing for new products and business initiatives
• Partner with business and technology stakeholders to define scalable, viable architecture approaches prior to development

Cross-Platform Architecture & Strategy

• Drive architecture across a hybrid, multi-technology environment, including:
  • Mainframe platforms (core system of record)
  • Distributed systems and application services
  • API and integration architecture
  • Cloud and microservices-based platforms
• Ensure solutions balance modernization, scalability, resiliency, and platform stability

Cross-Functional Partnership

• Collaborate closely with Product, Engineering, and Business leaders to shape solutions
• Translate business needs into clear, scalable architectural designs
• Partner with Enterprise Architecture and platform teams to ensure alignment to broader strategy

Technical Leadership & Decision-Making

• Provide oversight of conceptual architecture design across systems and integrations
• Drive technical tradeoff decisions and long-term architecture strategy
• Influence senior stakeholders through clear, executive-level communication

Basic Qualifications

• 10+ years of experience in software engineering, architecture, or related roles
• Experience leading architecture teams or senior-level architects
• Deep expertise in designing across:
  • Mainframe systems (required)
  • Distributed systems and application architectures
  • APIs and integration patterns
  • Cloud, microservices, and modern architecture patterns (e.g., domain-driven design, event-driven architecture)
• Experience supporting complex, high-availability platforms (e.g., payments, financial services, or similar)
• Ability to lead across legacy and modern technology environments simultaneously
• Experience with solution feasibility, sizing, or pre-development architecture work

Preferred Skills/Experience

• Experience supporting payments or card processing platforms
• Experience in highly regulated, mission-critical environments
• Exposure to cloud transformation and hybrid architecture strategies
• Strong executive communication and stakeholder influence skills

What Sets This Role Apart

• Leads architecture strategy and design, not delivery execution
• Owns architecture across both legacy and modern platforms
• Operates at the intersection of technology, product, and business strategy
• Plays a critical role in modernizing a core, enterprise-scale platform
