• Lead the design and implementation of cloud‑native integration solutions using modern AWS services and patterns
• Build and maintain secure, scalable, and reusable APIs that expose core business and data capabilities
• Apply API‑first and contract‑driven design principles to support long‑term reusability and governance
• Implement synchronous, asynchronous, and event‑driven integration patterns as appropriate
• Own and lead the engineering delivery of core data hubs and integration‑led data pipelines
• Design and implement reliable, high‑quality data pipelines aligned with HL’s SDLC and architectural principles
• Collaborate with the Data Platform team to ensure solutions align with AWS and Snowflake standards
• Contribute to the consolidation and distribution of key data domains into reusable data products
• Design and implement automated testing strategies across integrations, APIs, and data pipelines
• Drive towards a gold‑standard, fully automated testing suite, including unit, integration, data quality, and contract testing
• Embed build, test, and deployment processes into CI/CD pipelines using DevOps best practices
• Ensure solutions are observable and production‑ready through logging, monitoring, alerting, and resilience patterns
• Work across integration, data, and platform teams to enable consistent engineering patterns and standards
