As a Senior Technologist, you will be at the heart of the action, designing the systems that power our most sophisticated risk-based calculations.

  • Design and deliver a suite of "intelligent data APIs" that provide flexible, on-demand access to both aggregated and non-aggregated risk data for teams across the firm.
  • Integrate Natural Language Processing (NLP) capabilities to create intuitive, query-based interfaces for data exploration, lowering the barrier to entry for complex analytics.
  • Load and model massive aggregated datasets into high-performance OLAP engines like Apache Pinot, Apache Druid, and Trino.
  • Build powerful, interactive analytical tools and dashboards on top of the OLAP layer, providing summary views and lightning-fast drill-down capabilities.
  • Partner directly with senior stakeholders in the Front Office, Quantitative teams, and Risk Management to understand their analytical needs and deliver innovative solutions.


What We're Looking For

  • A degree in a quantitative or technical field such as Computer Science, Financial Mathematics, or Financial Engineering.
  • Expert-level, hands-on experience with big data technologies, particularly Apache Spark.
  • Proven experience with high-performance OLAP databases such as Apache Pinot, Apache Druid, or Trino.
  • Strong programming skills in Python, Java and/or Scala, and expert-level SQL.
  • Strong background in fundamental computer science concepts, including data structures and algorithms.
  • A mindset for 'AI-first' development, constantly looking for ways to embed intelligence into systems.
  • Experience or a strong interest in applying Natural Language Processing (NLP) to data access and analytics.
  • A knack for solving 'needle in a haystack' problems, with a talent for debugging complex data and access issues.
  • Experience in the financial industry with an understanding of market risk, derivatives, and risk calculations (VaR, Stress Testing, PV) is highly desirable.
  • Exceptional problem-solving skills and the ability to work independently and lead technical projects.
  • Excellent communication skills, with the confidence to collaborate with senior business and quantitative stakeholders.
