Key Responsibilities

Architecture & Design

• Own high-level and detailed architecture for complex mainframe applications, APIs, integrations and modernization initiatives.

• Convert functional and non-functional requirements into blueprints, component designs, interface contracts and implementation guidance.

• Select appropriate architecture patterns and assess trade-offs across scalability, performance, security, cost and maintainability.

• Ensure alignment with enterprise standards, approved platforms, reusable patterns and target-state roadmaps.

Technical Leadership & Governance

• Give hands-on architectural direction to development, QA, DevOps, security and support teams.

• Set coding, API, integration, logging, configuration, testing and deployment standards.

• Run architecture reviews, design walkthroughs, technical risk assessments and PoC evaluations.

Security, Reliability & Performance

• Embed secure-by-design across identity, authorization, secrets, data protection and interface security.

• Define resiliency patterns — retry, timeout, failover, HA and DR — plus performance and capacity targets.

• Ensure observability through structured logging, metrics, tracing, dashboards and alerting.

Stakeholder Engagement

• Facilitate technical discovery with business, product, security, infrastructure and vendor stakeholders.

• Communicate complex decisions clearly to engineering and leadership audiences.

• Maintain architecture artifacts, decision records, risk logs and technical roadmaps.

Key Responsibilities

Technology Focus — Mainframe

• Design, develop and support COBOL/CICS/DB2 batch and online components within agreed standards.
