    Equities Quant Platform Engineering Lead – Python (Technology) – VP

    Overview

    Citi is a world-leading global bank. We have approximately 200 million customer accounts and a presence in more than 160 countries and jurisdictions worldwide. We provide consumers, corporations, governments, and institutions with a broad range of financial products and services, including consumer banking and credit, corporate and investment banking, securities brokerage, transaction services, and wealth management. We enable clients to achieve their strategic financial objectives by providing them with cutting‑edge ideas, best‑in‑class products and solutions, and unparalleled access to capital and liquidity.

    What We do / The Team

    Are you a passionate and experienced engineering leader eager to build high-impact front office quant tools? Citi's Equities Technology team is undergoing significant growth and investment, specifically within our high‑priority systematic trading and analytics systems. We are seeking a hands‑on Engineering Lead to drive the development of our next‑generation quantitative development platform serving the Equities Cash, Derivatives, and Prime businesses.

    This is a unique opportunity to make a significant impact as the platform enters its key growth phase. You will be instrumental in shaping critical capabilities including building an event‑driven equity options back tester and AI‑powered data agents delivering market intelligence via rich dashboards. If you thrive in a fast‑paced, collaborative environment and have a passion for markets and quantitative research, we want to hear from you

    Role Overview/What will you do:

    As the Engineering Lead, you'll guide the technical direction and implementation of the platform. This involves:

    • Championing engineering excellence through hands‑on feature creation, rigorous code quality via pull‑request reviews, and by mentoring junior engineers to establish robust coding standards and guardrails.
    • Architecting scalable, secure re‑usable components. You'll drive the design process, aligning with or challenging existing blueprints, seeking consensus from senior leads and stakeholders.
    • Staying up to date with open‑source solutions and latest trends to accelerate business outcomes.

    Key Skills and Experience required

    • Extensive background in delivering production‑grade, data‑centric applications for quantitative trading and analytics, with demonstrated expertise in:
      • The python data engineering stack (Polars, Parquet, FastAPI, Jupyter, Airflow, Streamlit, Ray)
      • High-performance data stores and query engines (Starburst, Snowflake)
      • Real‑time streaming analytics technologies (Kafka, Flink)
      • Cloud container technologies (AWS, Azure, GCP, Docker, Kubernetes)
    • Proven success in enhancing developer experience that reduces friction in coding, building and deploying APIs and client libraries.
    • Real‑world application of generative AI prompt engineering and RAG pipelines.
    • Full‑stack HTML5 web development skills.

    Desired Skills:

    • Understanding of Equities Cash, D1 & Deriv market mechanics and products via sell‑side trading projects
    • Familiarity with low‑latency programming languages such as Rust or C++

    What we'll provide you

    By joining Citi London, you will not only be part of a business casual workplace with a hybrid working model (up to 2 days working at home per week), but also receive a competitive base salary (which is annually reviewed), and enjoy a whole host of additional benefits such as:

    • 27 days annual leave (plus bank holidays)
