Lead Software Engineer

Citi is looking for a Lead Software Engineer to architect and deliver next-generation Agentic AI applications at the intersection of full-stack engineering and large language model integration. In this senior role, you will define the technical direction for AI-powered platforms, lead teams of engineers, and build production-grade systems that power autonomous, multi-agent workflows across Citi's global technology organization. This is a rare opportunity to shape how Agentic AI is designed, deployed, and governed at enterprise scale within one of the world's largest financial institutions.

Responsibilities

• Architect secure, resilient, and high-performance full-stack applications designed to support complex Agentic AI workflows at enterprise scale.

• Lead hands-on development across the full application stack — from React and TypeScript frontends to Python and Java microservices and RESTful/gRPC APIs — ensuring code is clean, modular, and production-ready.

• Design and implement stateful, multi-turn, and multi-agent AI workflows using frameworks such as LangChain, LangGraph, CrewAI, AutoGen, or Semantic Kernel.

• Integrate applications with Citi's secure LLM gateway to access and manage AI models from Azure, Vertex, and other providers, including token usage, rate limits, and billing analytics.

• Establish and enforce technical standards, design patterns, and engineering best practices for full-stack development and AI agent integration across teams.

• Architect data models and integrate with relational and vector databases to enable stateful AI operations across complex, data-intensive workflows.

• Lead and develop multiple engineering teams, owning performance evaluations, hiring decisions, and the technical growth of team members.

• Evaluate emerging AI frameworks and tooling to evolve the technical stack and maintain a competitive engineering capability.

Required Qualifications & Skills

• 6 or more years of software engineering experience, with demonstrated ownership of technical delivery and team leadership across complex, large-scale programs.

• Deep expertise in frontend development using React, TypeScript, HTML5, and CSS3, with a focus on building responsive, accessible, and production-grade user interfaces.

• Advanced proficiency in Python (FastAPI, Flask, Celery) and/or Java (Spring Boot, Spring Cloud) for building scalable backend services and APIs.

• Proven ability to design and build Agentic AI and LLM-integrated systems, with applied knowledge of Retrieval-Augmented Generation (RAG), vector embeddings, and semantic search.

• Hands-on experience with Kubernetes, Red Hat OpenShift, Docker, and CI/CD platforms such as Harness, Jenkins, or Tekton for cloud-native deployments.

• Solid command of enterprise security principles, including OAuth2, OIDC, TLS, and secrets management using tools such as HashiCorp Vault.

• Experience designing and querying both relational databases (PostgreSQL, Oracle) and NoSQL databases (MongoDB, Couchbase) within production environments.

• Bachelor's degree or equivalent practical experience in Computer Science, Engineering, or a related field.

Beneficial Skills & Qualifications

• Experience deploying and managing agents on enterprise Agentic AI runtime platforms, with familiarity around network policy compliance, egress controls, and resource governance.

• Familiarity with Model Context Protocol (MCP) for mediating agent interactions with downstream business systems and databases.

• Experience with NoSQL and vector database technologies such as Milvus or Pinecone in support of AI-native data architectures.

• Master's degree in Computer Science, Software Engineering, or a related discipline.

What We Offer
