Job summary

The Cavaliers Holdings LLC is seeking a part-time Data Steward to help maintain and improve the data foundation that drives our business. This 20-hour-per-week role offers flexible scheduling and hands-on work on real systems from week one.

No sports background required; you will gain operational data experience and interact with engineers, analysts, and data owners to ensure accurate, well-documented data foundations.

Qualifications

• Willing to learn SQL. You’ll use it constantly and we’ll teach you.
• Genuinely detail-oriented. This role catches the things other people skim past
• Reliable and self-directed. You’ll work a queue with light supervision and we need to trust that finished means finished
• Comfortable writing clearly for other people to read. Plain, specific, no fluff
• Willing to ask the same clarifying question three times to three different people to get an answer right
• Able to work a consistent weekly schedule, with some overlap with our core hours for questions and handoffs
• Exposure to Git, pull requests, or Markdown. We’ll teach it, but a head start helps
• Familiarity with relational databases (PostgreSQL preferred)
• Any experience with data documentation, data catalogs, or dbt YAML files is preferred
• Comfort with AI assistants as a working tool. Our team uses them daily and you’re encouraged to
• Background in sports, entertainment, ticketing, or CRM data is a plus

Responsibilities

• Work a stewardship Kanban queue with a strict work-in-progress cap: pick up an item, finish it, move to the next
• Document datasets, tables, and columns: what they mean, who owns them, whether they’re still in use. Definitions go in the repo next to the code, submitted as pull requests
• Track down the person who actually knows what a field means, ask the question, and turn the answer into a written definition. Every subject‑matter‑expert conversation produces a documented change, not just notes
• Spot‑check and validate data: null checks, duplicate checks, row counts against expectations, does this month look like last month
• Verify recurring vendor file exchanges landed correctly and completely, and escalated when they didn’t
• Maintain the data dictionary and domain documentation on our internal portal so it stays current instead of going stale
• Flag data quality issues with enough context that an engineer can act on them without re‑investigating from scratch
• Help identify unused and stale datasets as deprecation candidates
• Assist with access reviews: confirm who has access to what and whether they still need it
• Post a short weekly written update on what moved, what’s blocked, and what’s next
