Specialist, Software Engineer – IBM ACE & ETL (Integration Specialist)
Build the connections that keep Commercial Lines moving

Nationwide Technology is looking for a technically curious, delivery-focused Specialist Software Engineer to strengthen and modernize the integrations that power Commercial Lines. In this role, you will design, build, test, troubleshoot, and support enterprise integration solutions using Informatica ETL, IBM App Connect Enterprise (ACE), IBM MQ, REST and SOAP services, databases, microservices, and API platforms such as Apigee.

You will work at the intersection of real-time messaging, API orchestration, data transformation, and batch processing. Your work will help move policy transaction data securely and reliably between Policy Center, internal applications, downstream platforms, vendors, and regulatory consumers.

This is an opportunity to bring fresh energy to critical integration capabilities while improving reliability, observability, maintainability, and developer experience.

The Integration Layer: ACE and Informatica ETLACE and Informatica ETL are complementary capabilities within the Commercial Lines Integration Layer. ACE supports real-time application, messaging, API, and service integration, while Informatica ETL extracts, transforms, and loads data across operational systems, analytical processes, files, vendors, and downstream consumers. This position is designed for an engineer who wants to develop a broad integration skillset by executing work across both disciplines.

You will build expertise in designing dependable data movement patterns end to end: receiving and parsing messages, orchestrating APIs and services, extracting data from source systems, applying business and data-quality transformations, loading curated outputs, and supporting the operational flow across environments.

What you’ll do Design, enhance, deploy, and support IBM ACE integration flows that connect applications, services, databases, and external partners.

Build message flows using MQ, HTTP, REST, SOAP, Compute, Flow Order, Failure, Catch, and other ACE nodes.

Implement secure API and service integrations, including OAuth 2.0 authentication and authorization, token acquisition, header management, endpoint invocation, response handling, and error processing.

Develop microservices and API-led integrations that are scalable, resilient, reusable, and aligned with enterprise integration standards.

Configure and troubleshoot MQ Input and MQ Output nodes, including transactionality, MQ order properties, MQ transaction mode properties, and message delivery behavior.

Apply and troubleshoot Compute node mode properties, including Compute mode transaction mode properties, to control message propagation and transaction boundaries.

Design robust Failure Terminal and Catch Terminal handling patterns for recoverable errors, technical exceptions, business exceptions, retries, alerts, and operational support.

Analyze message parsing behavior across common formats and configure flows to correctly parse, validate, route, and transform message payloads.

Apply data mapping and transformation techniques across XML, JSON, copybooks, service payloads, database records, and downstream file layouts.
