  • BI analysts (insights & reporting)
• Turn messy business questions into clean, scalable data solutions

⚙️ Build It Right

• Set standards for:
  • Data quality
  • Dashboard performance
  • BI best practices
• Introduce versioning, testing, CI/CD for BI if it’s missing

🛠️ What You BringMust-Have

• Strong SQL + solid data modeling skills
• Experience working with multiple messy data sources
• Python (or similar) for data work
• Experience with cloud data warehouses (Snowflake / BigQuery / Redshift)

Big Bonus Points

• iGaming / betting / high-scale transactional experience
• Experience embedding ML into BI
• Exposure to privacy tech / MPC
• Familiarity with modern data stack (dbt, Airflow, etc.)
• Real-time data experience

🧠 How You Work

• You take ownership-no waiting for perfect specs
• You care about impact, not just output
• You can talk to engineers and business stakeholders
• You simplify complexity and make data usable

🎯 What You’ll Impact

• Faster, better decisions across the company

You will take end-to-end ownership of our data infrastructure: from architecting high-performance storage on our VAST platform to designing the pipelines that deliver clean, reliable market data to traders and researchers. This is a high-ownership role in a small, fast-moving team where your work directly shapes our research and trading capabilities.

What You'll Do:

• Develop metadata and catalog layers for efficient data discovery and self-service access across the firm
• Design event-driven architectures for near real-time market data processing and delivery

• Conduct structured intake sessions with quant researchers to map their data access patterns, query workloads, latency needs, and iteration cycles

   

What We're Looking For

• 5+ years of experience in data engineering or data platform roles, with proven large-scale infrastructure ownership (100TB+)
• Strong understanding of market data structures: trades, quotes, order books, corporate actions
• Production-grade Python and SQL; experience building APIs (FastAPI or equivalent)
• Experience with DAG orchestration tools (Prefect, Airflow or similar)
• Deep familiarity with binary columnar storage formats (Parquet, Feather/Arrow IPC), including encoding strategies, compression tuning, row group sizing, predicate pushdown and schema evolution trade-offs
• Design namespace structure, tiering strategies, and protocol selection (NFS/S3) on VAST, optimizing for mixed workloads (experience with Vast Database and Vast Data engine is a plus)
• Bachelor's in Computer Science, Engineering, or equivalent; 
• Quantitative finance background is a plus

What We Offer:

• Competitive compensation with a performance-based bonus
