Working at Citi is far more than just a job. A career with us means joining a team of more than 230,000 dedicated people from around the globe. At Citi, you’ll have the opportunity to grow your career, give back to your community and make a real impact.

Job Overview

Minimum Qualifications

• Bachelor's degree in Computer Science, Data Science, Artificial Intelligence, or a related quantitative field.
• 8–12 years of experience as a Data Scientist or equivalent role, with at least 2 years of specialized, hands-on experience in Generative AI, including leading technical development and mentoring teams.
• Demonstrable experience across the full lifecycle of production-level GenAI projects — from ideation and prototyping through deployment, monitoring, and ongoing maintenance in live environments. Proof-of-concept work alone is insufficient.

Core Responsibilities

• Working with financial and enterprise data, applying modern NLP and GenAI techniques to solve business problems.
• Designing, refining, and systematizing prompt engineering strategies for large language models (LLMs), including structured prompting, chain-of-thought, and few-shot/zero-shot approaches.
• Collaborating with business stakeholders to translate requirements into GenAI-powered solutions.
• Developing, testing, and maintaining production-grade Python code for GenAI applications.
• Integrating with vector databases (e.g., Pinecone, Weaviate, Milvus, pgvector, Qdrant) for retrieval-augmented generation (RAG) pipelines.
• Building, monitoring, and optimizing MLOps/LLMOps pipelines for continuous model deployment and observability.
• Researching and evaluating emerging GenAI technologies, frameworks, and best practices to maintain competitive advantage.
• Troubleshooting and debugging GenAI models and agentic systems in production, including rapid identification and resolution of issues in real-world deployments.
• Communicating complex AI/ML concepts clearly to non-technical stakeholders, translating technical jargon into actionable business terms.
• Participating in and leading team meetings, design reviews, and architecture discussions.

Technical Skills

Programming & Foundations

• Expert-level Python proficiency, including:
• Core Python: data structures (lists, dictionaries, sets), algorithms, object-oriented programming, async programming, file handling, and exception handling.
• Scientific computing: NumPy, Pandas, SciPy.

Machine Learning

• Scikit-learn, XGBoost, LightGBM.
• Strong understanding of advanced modeling techniques, model evaluation, hyperparameter tuning, and deployment strategies.

Deep Learning

• PyTorch (preferred/primary), TensorFlow/Keras.
• Familiarity with training, fine-tuning, and inference optimization for neural network architectures.

MLOps / LLMOps

• CI/CD for ML/GenAI pipelines (e.g., GitHub Actions, GitLab CI).
• Experiment tracking and model registry (MLflow, Weights & Biases).
• Containerization and orchestration: Docker, Kubernetes.
• Infrastructure-as-code and deployment automation.

Cloud Platforms

• Proficiency in at least one major cloud platform's AI/ML services:
• AWS (Bedrock, SageMaker, Lambda)
• Azure (Azure OpenAI Service, Azure AI Studio, Azure ML)
• GCP (Vertex AI, Gemini API)

Soft Skills

• Excellent communication and collaboration skills — both written and verbal — with the ability to effectively convey technical concepts to diverse audiences, including senior leadership and business partners.
• Ability to articulate the challenges, trade-offs, and successes of deploying GenAI solutions at scale.
• Proactive approach to continuous learning in the rapidly evolving GenAI landscape.

Preferred Qualifications

• Master's or Ph.D. in a relevant field (Computer Science, AI/ML, NLP, or related).
• Experience with MLOps/LLMOps and building robust, automated AI pipelines at enterprise scale.
• Deep understanding of cloud-native architectures and their application in GenAI workloads.
• Experience developing and deploying conversational AI and agentic AI solutions in production environments.
• Contributions to open-source projects, research, or publications in the field of Generative AI or NLP.
