Data Analyst, Quantitative Research

The Advantage Quantitative Equity team is hiring a Data Analyst to take ownership of the quality, reliability, and usability of the quantitative datasets that power our research and production investment workflows. The core of this role is to become deeply familiar with our data, how it is sourced, shaped, validated, monitored, and used, then build automated solutions that keep it clean and reliable at scale.

We’ll trust you to:

• Become a domain owner for key quant datasets (e.g., market data, fundamentals, corporate actions, identifiers/reference data) and develop a detailed understanding of their structure, lineage, and intended analytical use
• Onboard new datasets end-to-end: profiling, schema/coverage validation, identifier mapping, cross-source reconciliation, documentation, and support for productionization
• Build and maintain automated data validation and monitoring processes (completeness, timeliness, duplication, outliers, stale/missing series, mapping breaks), along with clear quality metrics and reporting, implemented in code, not spreadsheets
• Maintain datasets over time through routine checks, backfills, and improvements as vendor definitions, schemas, and business requirements evolve
• Investigate data issues impacting research or production workflows: triage, isolate root cause, quantify impact, coordinate remediation, and help prevent recurrence
• Write Python scripts, pipelines, and utilities to automate validation, onboarding, reconciliation, and monitoring workflows; collaborate with quant developers to harden and operationalize your solutions in production
• Maintain high-quality dataset documentation and operational runbooks (definitions, assumptions, known quirks, troubleshooting guidance), improving consistency and conventions across the data ecosystem
• Engage constructively with internal teams and external vendors when addressing data issues or evaluating new sources

You’ll need to have:

• Bachelor’s degree in a Quantitative Discipline (e.g. Statistics, Mathematics, Economics, Finance, Computer Science) or equivalent practical experience
• Strong familiarity with quantitative / financial / investment datasets (e.g., prices/returns, fundamentals, corporate actions, security master / reference data, macro / alternative data sets)
• Experience working with vendor datasets; comfort reconciling across sources and managing schema/definition changes over time
• Strong SQL skills: ability to write and optimize queries to validate, reconcile, and investigate issues across large analytical datasets
• Strong Python skills: write clean, maintainable scripts and pipelines independently. Comfort with pandas/Num Py, file I/O, scheduling, and building reusable utilities
• Strong analytical and debugging mindset; diagnose data inconsistencies systematically and drive fixes through to completion
• Strong communication and collaboration skills; effective in small, close-knit teams with direct stakeholder interaction
• Exposure to common time-series pitfalls in financial data (staleness, partial trading days, identifier changes, corporate action adjustments, point-in-time behavior)

It’s a bonus to have:

• Experience supporting production data pipelines and incident workflows (monitoring, alerts, runbooks, operational readiness)
• Familiarity with modern data warehouses (e.g., Snowflake) and/or analytical engines (e.g., DuckDB/Polars)
• Cloud experience, preferably Azure
• Familiarity with containers and orchestration (e.g., Docker, Kubernetes) and CI/CD practices
