Oddball is seeking a System Architect to serve as the senior technical authority for FISS, a large Medicare Part A claims-processing platform running on a COBOL mainframe. The role governs architectural integrity, technical standards, modernization decisions, and safe changes across COBOL, CICS, and VSAM workloads. It requires designing integrations between legacy mainframe systems and AWS-hosted, API-based services while partnering with Java and modernization engineers. This is a contingent key-personnel position supporting a federal contract opportunity and may involve pre-award activities. Candidates must be authorized to work in the United States and may need to meet federal background investigation or clearance requirements. ## Role DNA A quick view of the complexity, pace, ownership and collaboration implied by the job description. ### Job Complexity 5/5EasyHard ### Pace & Pressure 4/5RelaxedFast-paced ### Autonomy Level 5/5GuidedFull ownership ### Communication Load 5/5IndependentCollaborative AI insightThe architect owns technical decisions for a high-stakes, multi-million-line healthcare claims system where reliability and safe modernization are critical.

I would introduce incremental, well-tested interfaces around stable mainframe capabilities, use phased releases with rollback plans, and measure reliability throughout the modernization effort. What considerations are important when integrating CICS and VSAM-based applications with cloud APIs? Key considerations include transaction integrity, latency, data consistency, security, error handling, and observability. I would use controlled integration layers, define clear contracts and idempotency behavior, and ensure API calls do not compromise core CICS transaction performance or recovery procedures. Describe your approach to setting architecture standards for a mixed legacy and cloud environment. I establish lightweight but enforceable standards for interfaces, security, data ownership, logging, resilience, testing, and change control. Standards should be documented, reviewed with delivery teams, and supported by architecture reviews that focus on risk reduction and delivery practicality. How would you handle a critical production issue involving a recent mainframe change? I would first stabilize the service by following incident procedures, assessing impact, and rolling back or isolating the change when appropriate. I would coordinate technical responders, communicate status clearly, validate data integrity, and lead a blameless root-cause review that results in preventive controls. How do you explain complex architectural tradeoffs to program leaders and non-technical stakeholders? I translate technical choices into outcomes such as claims-processing continuity, delivery risk, cost, compliance, and timeline impact. I present concise options with recommendations, assumptions, and mitigation plans so stakeholders can make informed decisions without needing implementation-level detail.
