• Champion AI-assisted development based on detailed specifications as a core engineering practice across teams. Lead by example using tools like Cursor, Claude Code, and Kiro - and actively drive adoption so the broader engineering organization evolves with the industry.
• Architect, build, and integrate RAG-based solutions and Agentic AI workflows into enterprise systems.
• Lead design and delivery of Java/Spring Boot backend services and Databricks/Spark data platform solutions - the two anchors of our current production stack.
• Provide technical leadership in architecture reviews, sprint planning, and code review sessions; enforce coding standards and engineering guidelines.
• Mentor and develop engineers across the team. Focus especially on development practices guided by artificial intelligence and production-quality engineering.
• Collaborate across product, data, platform, and cross-functional teams to plan and deliver features aligned with the Epsilon PeopleCloud Platform.
