• Contribute to architectural decisions and help shape the technical direction of the platform.

• Develop and integrate AI/LLM-powered features, agents, and workflows.

• Leverage AI-assisted development tools to improve engineering productivity while maintaining high standards for code quality and reliability.

• Identify opportunities to improve system performance, scalability, tooling, and engineering processes.

• 5+ years of professional Python experience building and maintaining production-grade systems.

• Strong professional experience with Java.

• Hands-on experience building AI/LLM-powered applications, AI agents, agentic systems, or LLM integrations.
