Key Responsibilities

Develop and maintain a centralized treasury management and balance sheet reporting system. Build data pipelines and interfaces to aggregate firm-wide financial positions from trading PnLs, capital allocations, and liquidity reports. Develop user-friendly front-end environments (likely via Google Sheets or web UIs) for internal reporting, supported by scalable back-end infrastructure. Collaborate across trading, operations, and finance teams to align technical implementation with business requirements. Ensure accuracy, completeness, and auditability of the firm's equity reporting and capital allocations.

Strong Python skills, including building back-end services, data integration pipelines, and API interactions. Deep familiarity with Google Sheets including Apps Script, integrations, and automation. Experience designing systems that interact with multiple business units and data types. Solid understanding of balance sheet mechanics, treasury operations, and capital/equity reporting. Strong problem-solving ability, attention to detail, and a proactive mindset.

Preferred / Desirable Experience

Experience with financial reporting, treasury platforms, or internal control systems in trading firms. Familiarity with web front-end development (e.g., React.js) to create lightweight internal dashboards. Exposure to Docker, AWS, Redis, and other infrastructure or DevOps tools. Understanding of how trading PnL, margin, and settlement interact with firm equity. Prior experience working closely with Traders, Finance, or Risk Teams.
