Job Overview
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
Joining Citi means working on technology that operates at global scale, with the scope and resources to make a genuine impact.

A hybrid working model with 3 days in the office and 2 days working remotely, giving you the structure of collaboration alongside meaningful flexibility.
Strategic ownership over high-impact engineering decisions that influence how AI systems are built and deployed across Citi globally.
Exposure to advanced AI and LLM infrastructure at a scale few organizations can offer, keeping your technical capabilities at the forefront of the industry.
Continuous learning and development opportunities, including access to emerging tools, frameworks, and engineering practices as they evolve.
A performance-driven environment where your contributions to delivery, architecture, and team development are recognized and rewarded.
Competitive financial wellbeing support, including compensation and benefits designed to reflect the seniority and scope of this role.
The ability to lead, mentor, and grow engineering teams, building lasting capability and technical culture within a global organization.
