Data Analyst, Antifraud
Higgsfield, Almaty, Kazakhstan
What you need
- 2+ years doing investigative or risk analytics — fraud, abuse, trust and safety, AML, chargebacks, gaming or marketplace integrity. What matters is that you have chased real bad actors, not modelled them in the abstract.
- Strong SQL, without help. Self-joins, window functions, cohort replay, and joining payments to usage to identity across messy keys. This is the single most-used skill in the role.
- Python at working level for analysis – pandas, notebooks, a bit of graph work.
- Investigative instinct: you follow the thread, you notice the thing that does not fit, and you can say when a pattern is a coincidence.
