This Role

The Software Engineer role entails responsibilities within our engineering department spanning a number of domains—from data engineering to workflow development. As an integral member of the team, you will collaborate closely with senior engineers, researchers, and other stakeholders to identify requirements and build robust internal tools.

• Using modern, proven architectural designs to enhance existing and build new APIs, frameworks, CI/CD pipelines and testing suites
• Performing data analysis and reconciliations to validate system functionality
• Contributing to the firm's AI buildouts—integrating LLMs and AI-assisted workflows into internal tools, research pipelines, and developer tooling

The role requires solid understanding of engineering principles, very strong programming capabilities, strong communication skills, collaborative spirit, and an analytic orientation.

• Strong problem-solving skills
• A strong sense of ownership and responsibility for one's work

• Working knowledge of one or more of C#, JavaScript, or TypeScript (exposure to frameworks such as Angular or React is a plus)
• Working knowledge of Python (helpful but not required)
• Comfort developing front-ends
• Familiarity with AI-assisted coding tools (e.g., Claude Code, Cursor, Copilot) and a thoughtful approach to using them in production codebases
• Exposure to mortgage-backed securities, whole loans, structured products, portfolio management systems, or accounting systems a plus

Bachelor's or Master's degree in Computer Science or a related engineering discipline (e.g., Electrical Engineering) required. Recent graduates and candidates with up to three years of experience are encouraged to apply, including those with relevant internships, technical projects, or open-source contributions.
