Title: Full-Stack Engineer Job Type: Contract Contract Length: Through December 31, 2026 Pay Range: $70–120/hr Start Date: ASAP Location: Hybrid - Boston, MA (3 days a week onsite) About the Opportunity 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. Key Responsibilities & Deliverables Front-End Development (60% Focus): Build, test, and enhance tools that attribute drivers of portfolio positions, returns, and risk. Develop front-end components using TypeScript 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. Required Skills & Experience 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 TypeScript, 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. Preferred Experience 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. #J-18808-Ljbffr
