GenAI Developer

We are looking for an enthusiastic Generative AI Developer to join our Controls Technology team and support the development and integration of generative AI solutions. In this hands-on role, you will work under the guidance of senior developers and AI architects to help build retrieval-grounded, context-aware, and increasingly agentic AI applications. You will contribute to reliable, AI-driven features while growing your expertise across the modern GenAI stack. This role focuses on applying pre-trained and hosted foundation models — through context engineering, RAG, knowledge graphs, and agentic workflows — rather than training or fine-tuning models. This is a growth-oriented role: you'll take ownership of well-scoped components, learn established patterns from senior engineers, and progressively increase your technical depth and independence. # Key Responsibilities * Assist in building and integrating generative AI applications using pre-trained and hosted foundation models (via managed GenAI APIs and open-model endpoints). * Support the implementation of context engineering workflows — assembling system instructions, retrieved knowledge, tool definitions, and conversation memory into reliable, token-efficient prompts, following established patterns. * Contribute to prompt engineering (zero-shot, few-shot, chain-of-thought, role-based prompting) for AI-powered workflows. * Help develop and maintain Retrieval-Augmented Generation (RAG) components, including chunking, embedding, and semantic/keyword search. * Support the development of knowledge graph and Graph RAG pipelines under guidance to enable grounded, traceable responses. * Contribute to agentic workflows — helping build AI agents with tool-calling and basic planning/memory, using frameworks such as Google Agent Development Kit (ADK), LangGraph, or CrewAI. * Assist with integrating agents to external tools and data sources via the Model Context Protocol (MCP), with exposure to the Agent2Agent (A2A) protocol. * Support the deployment, monitoring, and maintenance of GenAI and agentic applications in production environments. * Perform data preprocessing, document ingestion, and basic API development for AI applications. * Collaborate with data scientists and engineers to integrate AI capabilities into products. * Participate in code reviews, testing, and documentation to ensure quality and reliability. * Stay curious about advancements in GenAI and agentic AI, and share learnings with the team. # Required Technical Skills * Proficiency in Python for GenAI development, data preprocessing, and scripting. * Solid understanding of core generative AI concepts — foundation models, LLMs, tokenization, embeddings, and context windows. * Hands-on experience with prompt engineering; foundational understanding of context engineering techniques. * Practical experience (project or professional) building RAG systems, including chunking, vector databases, and semantic search. * Familiarity with knowledge graphs and interest in Graph RAG for relationship-aware retrieval. * Exposure to agentic AI development — building tool-using agents or multi-step workflows with a framework such as Google ADK, LangGraph, CrewAI, or the OpenAI Agents SDK. * Awareness of agent tooling and protocols, including tool/function calling and the Model Context Protocol (MCP); familiarity with the A2A protocol is a plus. * Basic understanding of agent harness concepts — session/state management, memory, and guardrails. * Experience consuming major GenAI APIs (e.g., OpenAI, Gemini, Claude) and exposure to orchestration frameworks such as LangChain or LlamaIndex. * Understanding of application deployment and containerization (Docker). * Working knowledge of version control systems (Git). * Awareness of AI compliance, data privacy, guardrails, and responsible AI principles. # Required Soft Skills * Strong teamwork and communication abilities. * Eagerness to learn new AI/GenAI and agentic technologies and frameworks. * Analytical mindset and attention to detail. * Openness to feedback, coaching, and continuous improvement. # Qualifications * Bachelor's or Master's degree in Computer Science, Data Science, AI, or a related field. * 4+ years of experience with atleast 2–4 years of professional experience in software/AI development, with exposure to Generative AI and agentic AI. * Experience contributing to AI/GenAI or software projects in a collaborative team setting. * Exposure to cloud-based AI/ML environments (AWS, GCP, or Azure) is a plus. \------------------------------------------------------ ## Job Family Group: Technology \------------------------------------------------------ ## Job Family: Applications Development \------------------------------------------------------ ## Time Type: Full time \------------------------------------------------------ ## Most Relevant Skills Please see the requirements listed above. \------------------------------------------------------ ## Other Relevant Skills For complementary skills, please see above and/or contact the recruiter. \------------------------------------------------------ Citi is an equal opportunity employer, and qualified candidates will receive consideration without regard to their race, color, religion, sex, sexual orientation, gender identity, national origin, disability, status as a protected veteran, or any other characteristic protected by law.
