Fiserv Optis - SME

Role: Fiserv Optis - SME

Type of hire: FTC

Location: Buffalow, NY/ NY NJ or Wilmington, DE-

Note:- Remote will also work

Role Overview

You will serve as the hands-on Optis Debit SME and API Orchestration Lead, directly embedded with M&T and Mphasis teams to:

• Own the Optis debit migration path endtoend (not credit)
• Challenge and validate Fiserv guidance with facts and prior experience
• Drive Spring Boot/API orchestration for inbound auth shielding and outbound maintenance operations
• Accelerate retirement of TIBCO ESB by guiding patterns and leading rewrites with backward compatibility
• Stabilize delivery replace documentation gaps with executable tests, consistent mappings, and productionready designs

Key Responsibilities

Optis Debit Migration Leadership

• Lead solutioning for debit migration to Fiserv Optis, including field mappings, service behaviors, PCF settings, and platform constraints.
• Translate ambiguoincorrect Fiserv Developer Studio definitions into validated, testproven API contracts and payload structures.
• Define and document shielding patterns for inbound authorization traffic (Optis M&T) through the API layer.
• Create and maintain operational runbooks (error codes, retries, idempotency, timeouts, fallbacks, alerting).

API Orchestration & Delivery

• Design and build Java Spring Boot microservices for orchestration stateless, scalable, and containerized.
• Implement backward-compatible behaviors to minimize channel change (Digital, IVR, Branch).
• Lead ESB-to-API refactor (TIBCO Spring Boot), ensuring parity, observability, and resiliency.
• Define nonfunctional requirements (performance SLAs, throughput, concurrency, resilience patterns, failure isolation).
• Partner with SRE to establish logging, metrics, tracing, and production readiness.

Program Acceleration & Governance

• Establish a fact-based Optis knowledge base: tested examples, field dictionaries, PCF mappings, and channel matrices.
• Run integration spikes to derisk uncertain areas; build sandbox/test harnesses for empirical validation.
• Review designs, code, and test cases; mentor engineers and coach BAs on Optis specifics and orchestration nuances.
• Align designs and implementations with enterprise standards used in Garrett s area.

Required Qualifications

• 5 10+ years in debit card platforms with direct, handson Fiserv Optis (debit) migration/implementation experience.

Must be debit; credit-only experience is not sufficient.

• Expert-level Java/Spring Boot for API/microservice development; containerized deployment experience (Docker/K8s/OpenShift).
• Demonstrated success building orchestration layers (request routing, transformation, shielding, fault handling).
• Experience retiring legacy ESB services and refactoring to API-first architectures.
• Strong knowledge of authorization flows, card lifecycle events (lock/unlock, lost/stolen, PIN, status), and core banking touchpoints (e.g., Hogan).
• Proven ability to challenge vendor guidance constructively and back it with empirical tests and production evidence.
• Deep understanding of API security (gateway-based authN/Z), idempotency, transactional integrity, and backward compatibility strategies.
• Exceptional documentation and communication skills; able to align architects, BAs, channels, and vendor teams.

Preferred Qualifications

• Prior experience stabilizing programs that were behind schedule and under-resourced.
• Familiarity with Fiserv Developer Studio pitfalls and fieldlevel quirks (incl. PCF mapping).
• Observability: OpenTelemetry, distributed tracing, structured logging, servicelevel dashboards.
• Messaging/async patterns; resiliency engineering (circuit breakers, retries, bulkheads).
• Banking regulatory & operational awareness (SOX, PCI DSS, PII handling, auditability).
