You will work at the forefront of emerging technologies, including large language models, agentic systems, retrieval-augmented generation (RAG), evaluation frameworks, and cloud-native architectures. This role requires a hands-on technologist who is passionate about continuous learning, technical leadership, and delivering production-ready AI solutions that create measurable client value.

Primary technologies include Node.js, TypeScript, Python, AWS, AWS Bedrock, LangGraph, Gemini, MCP (Model Context Protocol), Arize, agent memory frameworks, and modern AI evaluation tooling.

Responsibilities:

• Design, develop, implement, and support scalable AI-driven applications, services, and platform capabilities that enable innovative client advice experiences.

• Architect and integrate solutions leveraging AWS Bedrock, large language models, agent orchestration frameworks, RAG architectures, agent memory, and multi-model ecosystems.

• Evaluate technical approaches and provide recommendations regarding system design, architecture, platform capabilities, third-party products, and build-versus-buy decisions.

• Develop, test, deploy, and monitor production-ready software solutions while ensuring reliability, scalability, performance, and security.

• Lead technical design reviews, code reviews, testing activities, and architecture discussions to maintain high engineering standards and solution quality.

• Troubleshoot and resolve complex technical issues across development, testing, and production environments; provide ongoing production support as needed.

• Establish and promote software engineering best practices, development standards, AI governance considerations, and secure development methodologies.

• Mentor and support engineers by sharing technical expertise, providing guidance, and fostering continuous learning across the team.

• Partner closely with product, design, data, and engineering stakeholders to translate client and business needs into effective technical solutions.

• Stay current on emerging technologies, AI platform advancements, and industry trends, identifying opportunities to improve Vanguard’s AI capabilities and client experience.
