Original job description

Citi’s Markets Technology group is modernizing financial risk management, and we are seeking an experienced Senior Python Engineer to sit at the center of that evolution. In this role, you will architect and scale robust backend systems, leveraging Generative AI to analyze massive volumes of unstructured financial communication - extracting trading signals, validating market behavior, and enhancing critical risk controls across Citi’s global markets infrastructure.

This is a high-impact, hands-on engineering position (~80% coding) where your technical contributions will directly influence next-generation risk and intelligence platforms at global enterprise scale.

Key Responsibilities

Design and implement advanced risk detection and analytics algorithms on Citi’s strategic platforms, integrating Generative AI foundational models to evaluate market activity and derive actionable intelligence from multimodal data (chat, voice, transcripts).
Apply advanced prompt engineering, token usage optimization, and Retrieval-Augmented Generation (RAG) techniques to develop efficient, production-grade solutions using Citi's proprietary data at scale.
Architect, build, and deploy resilient, distributed backend services and high-performance APIs across Kubernetes-orchestrated infrastructure.
Continuously research, benchmark, and integrate emerging LLM/GenAI paradigms, libraries, and frameworks to elevate platform capabilities and engineering velocity.
Partner with quantitative analysts, product owners, risk managers, and compliance teams to roll out features across platforms governing hundreds of risk controls.
Deliver clean, modular, and maintainable software backed by comprehensive unit testing, rigorous peer code reviews, and automated CI/CD pipelines.
Author and maintain architectural blueprints, system diagrams, and technical documentation to foster reliability and team-wide technical excellence.

Required Qualifications & Skills

4+ years of professional experience in Python for backend development, with the ability to design and build scalable, high-performance systems.
Hands-on experience applying Generative AI foundational models in production environments, with demonstrated expertise in prompt engineering and token usage optimization.
Practical knowledge of Kubernetes for deploying and operating scalable backend platforms and engineering high-performance APIs.
Solid command of software engineering fundamentals, including system design, data structures, and algorithms.
Ability to work independently, manage competing priorities, and deliver across multiple workstreams without close direction.
Bachelor's degree or equivalent professional experience.

Beneficial Skills & Qualifications

Exposure to processing and deriving insights from large volumes of unstructured or conversational data.
Preferred experience working in financial services or banking, with familiarity with trading workflows, market data, or financial risk concepts.
Strong communication and influencing skills, with the ability to align technical and non-technical stakeholders around shared goals.
Experience working across international, cross-functional teams and contributing to collaborative platform delivery.

What We Offer

At Citi, you will work on technology that operates at genuine global scale - contributing to platforms that process real financial data, support critical market operations, and place Generative AI at the heart of how risk is understood and managed. This is an opportunity to do technically ambitious work in a performance-driven environment that rewards ownership and continuous learning.

A hybrid working arrangement offering 3 days in the office and 2 days working remotely, providing flexibility alongside meaningful in-person collaboration.
Direct ownership of complex, high-stakes engineering challenges at the intersection of large-scale systems and cutting-edge AI - with real impact on financial markets technology.
Access to Citi's learning and development programs, supporting your growth as both a technical practitioner and a senior contributor.
Exposure to Generative AI applied in one of the most data-rich and technically demanding environments in financial services.
Competitive financial wellbeing benefits and compensation aligned to senior-level engineering contribution.
Wellbeing support and work-life balance initiatives designed to help you perform at your best over the long term.

How to Apply

Apply now to bring your Python engineering and Generative AI expertise to Citi's Markets Technology group - and help build the intelligent foundation powering global financial risk management.
