Mid-Level Data Scientist / Quant - Risk & Trading

About Sleeper

Sleeper is one of the fastest–growing sports platforms in the US. We build free‑to‑play fantasy titles and real‑money Daily Fantasy Sports (DFS) games across the NFL, NBA/WNBA, MLB, NHL, EU football, and more. Our Risk & Trading team safeguards game integrity and optimizes profitability through data‑driven pricing and exposure management.

What You’ll Be Doing

Feature engineering & model tuning – Own the pipelines that transform raw bet, player, and market data into features for our pricing and exposure models (BigQuery + SQLX, Python, Pandas).

Predictive modeling – Train, validate, and deploy supervised and probabilistic models that forecast player performance, market volatility, and user value.

Guardrail automation – Ship rule‑based limiters and anomaly‑detection jobs that run every few seconds, flagging and throttling outlier exposure before it becomes tail risk.

Dashboards & alerting – Build Grafana dashboards and SQLX reports that surface live liability, promo uptake, and top‑line KPIs to trading and exec stakeholders.

Light on‑call rotation – During peak sports windows, respond to automated alerts and, if necessary, execute a manual override (price suspension / limit change). < 2 hrs/wk on average.

Cross‑functional collaboration – Pair with Backend & Data Engineers to productionize models, and with Product to iterate on game mechanics and promos.

What We Offer

Sleeper believes in quality over quantity, and intentionally keeps our team small as a result. In past roles, we found it very hard to make a big impact when companies grow too large in size, which has a detrimental effect on the product and the impact any single individual can have. Our team includes designers, engineers, product experts, and finance & operation focused on one thing — connecting people over sports. We believe in fair and equitable pay. Certain locations in the United States require job postings to include a reasonable estimate of the base salary range and/or a general description of benefits and other compensation applicable to the role.

Competitive salary plus benefits including Medical, Dental, PTO, 401k.
