The SSIS Developer will be responsible for designing, developing, and maintaining ETL pipelines to extract data from the Guidewire Aurora Postgre

SQL database and load it into on‑premises SQL Server databases. This role plays a critical part in a major Guidewire upgrade/migration initiative and involves building a nightly batch cycle, ensuring data accuracy through reconciliation processes, and validating end‑to‑end data movement. The ideal candidate has strong ETL, SQL, and data migration experience within insurance domain systems.

• Strong hands‑on experience with SSIS (SQL Server Integration Services).
• Expertise in SQL Server (T‑SQL, stored procedures, triggers, indexing, query optimization).
• Experience extracting from Postgre
  
  SQL/Aurora using ODBC/OLEDB/.NET providers.
• Experience with data migration, large datasets, and performance tuning.

• Familiarity with Guidewire Policy Center, Claim Center, or Billing Center data models.
• Understanding of Guidewire Aurora database structures for PC/CC/BC.
• Experience working on Guidewire version upgrades or cloud migrations is a plus.

• Experience with ETL job scheduling (SQL Server Agent, Control‑M, Autosys, etc.).
• Experience using Git, Azure Dev Ops, Jenkins, or other CI/CD tools.
• Ability to write reconciliation scripts in SQL and/or Python (optional).
• Strong understanding of data quality, audit, and compliance practices.

• 5–8 years of ETL development experience, with at least 3+ years in SSIS.
• Prior experience in migration projects, preferably Guidewire or other insurance platforms.
• Strong analytical skills and ability to investigate data anomalies.
• Experience working in Agile/Scrum environments.
• Bachelor’s degree in Computer Science, Information Systems, Engineering, or equivalent experience.

• ETL Design & Development: develop SSIS packages to extract data from Guidewire Aurora (Postgre
  
  SQL) and load it into SQL Server databases; design scalable and optimized ETL frameworks supporting incremental loads, full loads, and delta logic; configure secure connectivity between cloud Aurora DB and on‑prem SQL Server; implement transformations, business rules, surrogate key management, and referential integrity through ETL.
• Nightly Batch Cycle Setup: design and orchestrate nightly ETL batch processes using SQL Server Agent or enterprise schedulers; implement error‑handling, retry logic, logging, and alerting for batch jobs; monitor performance and optimize slow‑running jobs to meet ETL SLAs.
• Data Validation & Reconciliation: conduct field‑level and record‑level reconciliation between Aurora and SQL Server tables; develop comparison scripts to validate counts, checksums/hashes, and business‑critical attributes; identify mismatches, perform root‑cause analysis, and coordinate with database and Guidewire functional teams to resolve issues; maintain audit trail, data lineage documentation, and reconciliation dashboards.
• Support Guidewire Upgrade/Migration: collaborate with Guidewire functional consultants to understand PC/CC/BC data models and changes introduced by the upgrade; perform data profiling to identify data gaps or transformation needs stemming from version differences; support parallel runs, cutover planning, and post‑migration validation; ensure ETL processes align with Guidewire data model standards and release cycles.
• Documentation & Delivery: create detailed technical design documents (TDD), mapping sheets, and ETL flow diagrams; maintain SSIS source code in version control (Git/Azure Dev Ops); provide post‑deployment support, including defect resolution, optimizations, and enhancements.
