Job description

Our client is seeking a Senior Data Engineer in Boston, MA. This is a direct hire role and onsite 3 days per week.

This is a hands‑on engineering role with real proximity to the business. You will work directly with portfolio managers, traders, finance, operations and research analysts — gaining exposure to the investment management process and contributing to the systems that give our investment teams a competitive edge. The ideal candidate is a well‑rounded technologist who is as comfortable defending a grain decision as they are pairing with an AI agent to refactor a pipeline.

You are a self‑starter with an ownership mindset who thrives in a fast‑paced, collaborative environment. You communicate complex technical concepts clearly to both technical and non-technical audiences, and you raise the bar for the people around you.

QUALIFICATIONS

• 5+ years in data engineering or a closely related software engineering role.
• Hands‑on, daily‑use experience with agentic AI coding tools — Claude, Codex, ChatGPT, Cursor, or equivalent — with a clear point of view on where they help, where they don’t, and how to keep their output correct, secure, and reviewable.
• Deep, demonstrable experience with Snowflake — performance, cost, RBAC/security, and warehouse/query design.

Preferred / Nice to Have

• Experience building internal AI/agentic tooling — MCP servers, retrieval, LLM-backed analytics assistants, or custom agents and skills.
• Orchestration tooling (Airflow, Dagster, dbt Cloud, or similar).
• BI/reporting experience, Power BI especially.
