• Build secure integrations with application services and governed data sources, including sandboxed code execution and AI-powered data visualizations.
• Design configurable solutions supporting client-specific prompts, tools, skills, and data definitions without duplicating the core architecture.
• Develop MCP servers and clients to enable communication and data exchange between agents and applications.
• Contribute to architectural decisions and the evolution and migration of the existing LangChain-based solution .
• Implement LLM evaluation, testing, observability, and security controls to ensure accurate, reliable, and data-grounded AI outputs.
• Own features end to end, from technical design and implementation to production release and continuous improvement, collaborating with cross-functional teams.

Essential Knowledge, Skills & Experience

Core Requirements

• 6+ years of experience in software engineering, data analytics, or related fields, including 2+ years in agentic AI engineering .
• Strong Python development skills, with experience building, testing, and maintaining production-grade applications.
