We are seeking a highly specialized Senior Capital Markets Data Modeler to spearhead the standardization, design, and governance of our global transaction data structures across Front, Middle, and Back-Office (FOMOBO) platforms. In this role, you will bridge the gap between complex quantitative trading concepts and real-time data engineering pipelines. Your primary mandate will be to translate complex trade lifecycles—spanning execution, valuations, and downstream clearing/settlements—into modern, event-driven data schemas. By leveraging standard financial messaging protocols alongside cutting-edge lakehouse tools, you will design the data backbone supporting high-velocity stream processing frameworks. Role Objectives

• Design End-to-End Trading Data Models: Create and maintain conceptual, logical, and physical data models capturing end-to-end multi-asset trade lifecycles across Front Office (execution/pricing), Middle Office (risk/valuations), and Back Office (settlements/reconciliations). • Implement Financial Standards (FpML & ISDA CDM): Serve as the Subject Matter Expert on FpML (Financial Product Markup Language) and the FINOS / ISDA Common Domain Model (CDM) to unify derivatives messaging and post-trade lifecycle state transitions across the enterprise. • Architect Event-Driven Schema Frameworks: Design highly performant, version-controlled streaming schemas (JSON Schema, Avro, or Protobuf) optimized for continuous pub/sub and event-sourcing architectural flows. • Optimize Databricks Lakehouse Structures: Partner with data engineers to materialize real-time event payloads into highly scalable Databricks Delta Lake tables using Medallion patterns (Bronze/Silver/Gold) optimized for time-series analytics and query performance. • Integrate Trade Workflow Engines: Model data interactions for stateful, orchestration-driven Trade Workflow Engines, ensuring exact tracking of trade status updates, validation overrides, and audit trails. • Enforce Data Lineage & Interoperability: Build comprehensive, automated data dictionaries and lineage mappings to ensure upstream trading desk schemas seamlessly reconcile with downstream regulatory reporting nodes. Qualifications and Skills

• Domain Expertise: 7+ years of experience as a specialized Data Modeler in an Investment Bank, Tier-1 Capital Markets Broker-Dealer, or Clearing House spanning Front, Middle, and Back Office operations. • Financial Modeling Protocols: Proven track record of direct, production-level implementation of ISDA CDM (Common Domain Model) and FpML frameworks for Over-The-Counter (OTC) derivatives, fixed income, or foreign exchange (FX) asset classes. • Technological Tooling: o Minimum 3+ years designing data structures specifically optimized for processing on the Databricks Unified Data Analytics Platform. o Mastery of schema modeling tools (such as ERwin, InfoSphere Data Architect, Hackolade, or Idera ER/Studio). • Distributed Streaming Patterns: Extensive knowledge of asynchronous message queue behaviors, schema evolution strategies (backward/forward compatibility), and stream-processing database normalization tradeoffs. • Trade Lifecycle Literacy: In-depth understanding of trade state mechanics handled by execution and workflow engines, such as allocation rules, novations, compression exercises, and margin calculations. Preferred Technical Additions • Working knowledge of SQL, Python, or Scala for testing, validating, and querying live Delta tables inside Databricks. • Prior involvement with industry bodies like FINOS, ISDA, or FIX Trading Community. • Familiarity with financial messaging formats like FIX Protocol or ISO 20022.
