The Specialist Software Engineer on the Commercial A-Team will focus on integration applications that enable policy transaction processing, downstream data movement, and operational support across Commercial Lines. This role will primarily support two integration domains: ACE (App Connect Enterprise) and CL ETL Batch. In ACE, the engineer will work on application and service integration, message routing, security, deployment, configuration, and data transformation between upstream and downstream systems. In CL ETL Batch, the engineer will support the pipeline that takes PolicyCenter transaction data through IDS/Oracle-based processing and transforms it into files, feeds, and reporting outputs used by downstream systems, vendors, and bureaus.

Primary focus areas

• Design, enhance, and support ACE integrations that connect PolicyCenter and other services through secure APIs, message routing, and payload transformation.

• Build and maintain ACE flows that obtain authentication tokens, invoke REST services, construct request payloads, apply field mappings, and return transformed responses to upstream applications.

• Support CL ETL Batch processing that consumes PolicyCenter transaction data from IDS Oracle after IIB/ACE processing and creates downstream extracts and statistical records.

• Deliver and support integrations and data feeds for business and regulatory consumers including Billing, Commissions, General Ledger, ISO/TICO, HSB, ISO/Verisk, WC PICS/Unit Stat, print, inforce, ECIF, AMI, SaRA, and PAM.

• Provide production support, issue analysis, and ongoing optimization for integration jobs, runtime behavior, and data processing outcomes.

Key responsibilities

• Own and enhance ACE integration solutions, including instance-level application support, updates, and alignment with enterprise integration standards.

• Analyze business and system requirements and translate them into API contracts, request/response mappings, transformation logic, and integration error handling.

• Develop and troubleshoot data mappings between PolicyCenter XML or service payloads and downstream schemas used by internal services, print, vendor feeds, and reporting outputs.

• Support ETL workflows that extract, transform, and publish data for line-of-business processing, statistical records, and operational file exchanges.

• Work with Oracle-based IDS data structures, job control metadata, and environment-specific parameters used to monitor, troubleshoot, and rerun processing flows.

• Support job scheduling and operational processing in a UNIX environment using established batch frameworks and Perl-based job control patterns.

• Partner with product, testing, and downstream business or technical teams to ensure integrations are reliable, supportable, and aligned to policy transaction needs.

Candidate skills and experience

• Strong integration engineering background with hands-on experience in IBM App Connect Enterprise or comparable middleware/integration platforms, including message routing, protocol connectivity, and data transformation.

• Experience with API and service integrations, including token-based authentication, REST request construction, header management, endpoint invocation, response parsing, and upstream response mapping.

• Strong data mapping and transformation skills across XML, JSON, and downstream record or file layouts.

• Experience working with batch data pipelines, file-based integrations, and downstream data feeds for operational or reporting consumers.

• Working knowledge of Oracle data environments, SQL-based troubleshooting, and environment-specific configuration or access patterns for development through production support.

• Understanding of deployment, security, and configuration concepts for integration runtimes.

• Experience supporting production incidents, job failures, data issues, and operational reruns in complex enterprise environments.
