Our client, a leader in Systematic Investment Management, is looking for a skilled Full-Stack Engineer to join their Portfolio Tools Engineering team for an engagement through December 31, 2026. This is a high-impact, execution-heavy project focused on owning and evolving one of the firm’s flagship internal software products—a market-leading portfolio management and decomposition platform. This is a high-impact role that requires a self-motivated professional who wants to build fast, scalable, and maintainable tools that drive real-time investment decision-making and can hit the ground running and deliver results quickly.

• Front-End Development (60% Focus):
  Build, test, and enhance tools that attribute drivers of portfolio positions, returns, and risk. Develop front-end components using Type Script and React, focusing on component design, state management, and performance optimization for data-heavy views.
• Back-End Engineering (40% Focus):
  Design and implement backend systems using Python, Ray, and databases for scalable, high-performance data processing.
• Architecture and Deployment:
  Implement cloud-ready, modular, and extensible solutions and optimize software systems for performance, scalability, and cloud deployment.
• Collaboration & Optimization:
  Collaborate with portfolio managers, quants, and engineers to align tools with investment workflows. Optimize and unify reporting across multiple geographies and strategies, including exception-based management reports.

• 4-6 years of full-stack development experience, including work on production systems.
• Deep expertise in Front-End Development (60% initial focus):
  Strong skills in Type Script, HTML/CSS, and React.
• Deep expertise in Python (40% focus):
  Strong backend engineering skills using Python, including API design and experience with databases. This isn't a learning role—you need to be a subject matter expert.
• Strong communication skills to provide clear and concise status updates to the project team.
• Ability to work as an effective team player and self-starter, willing to roll up their sleeves to help accomplish team goals in a fast-paced environment.
• Demonstrated ability to work autonomously and manage your own time effectively to meet project goals.

• Hands‑on experience with Material UI (MUI) and MUI X for building user interfaces and data visualizations.
• Experience with Ray and Pandas/Polars for distributed parallel computing.
• Some investment domain knowledge, particularly in portfolio decomposition, attribution, risk analysis, or quantitative equity strategies.
