Open role
Rewards Data Analyst
About Dafio
Dafio is built for people who carry four or more credit cards. It looks at how someone actually spends, points out where they are leaving money on the table, and tells them which card in their wallet earns the most on the purchase in front of them.
The role
You own the rules behind that answer. Card earn rates, category definitions, spending caps, annual fee math, transfer partner values and promotional offers all change constantly, and the recommendation is only as good as the data behind it. You keep that set correct and current, and you check what the app recommends against what the issuer actually pays. This is an analytical role that sits alongside product, not a customer facing one.
What you will do
- Maintain the card database, including earn rates by category, caps, fee schedules and welcome offer terms.
- Verify changes against issuer terms and conditions rather than secondhand summaries, and record the source and date.
- Audit recommendation output against real spending scenarios to confirm the named card is actually the best one.
- Analyze aggregate member spending to find category gaps where the app should be recommending better.
- Build monitoring that flags when an issuer changes terms so the database is updated before members are misled.
What we are looking for
- Two or more years in an analyst role working with transactional or product data.
- Strong SQL and comfort in spreadsheets at scale.
- Genuine interest in credit card rewards, including how category bonuses and caps really work.
- Attention to detail, since an earn rate off by one percent produces a wrong recommendation every time.
- The ability to write up findings so a product decision can be made from them.
Nice to have
- Prior work at an issuer, a card comparison site, or a rewards program.
- Experience with transaction categorization or merchant category codes.
- Python for data work, or familiarity with a BI tool such as Looker or Metabase.
