Aqilea; United States; A distancia; USD 120.000 - 180.000; Jornada completa

Descripción de la vacante

Aqilea is seeking an Analytics Engineer to own fraud forensics for its identity and verification platform, focusing on OTP verification and SMS pumping threats. You will analyze attacks, build rules, and monitor systems to protect signup flows.

You will develop end-to-end detection and alerting, document playbooks, and train teammates to sustain capabilities after your engagement ends. This is a remote, international assignment.

Formación

• 5+ years in analytics engineering, data science or fraud analytics, with at least 2 years hands-on in fraud or abuse detection.
• Expert SQL on BigQuery: large event tables, window functions, partition-aware and cost-efficient queries.
• Strong Python (pandas, notebooks) for ad-hoc forensics and pattern mining.
• Building scheduled pipelines in Airflow and dashboards in Looker (or equivalent BI).
• Experience tuning rule- or threshold-based fraud controls, including backtesting and false-positive analysis.
• Works independently from day one; communicates findings crisply to engineers and leadership.

Responsabilidades

• Fraud forensics: investigate active and past attacks on OTP and verification flows; quantify volume, cost and user impact; produce clear incident write-ups.
• Attack triage: identify patterns across country, carrier, number range, device and attestation signals; separate SMS pumping, bot traffic and account abuse from legitimate spikes.
• Threshold tuning: analyse and backtest anti-fraud rules and thresholds; quantify false positives against fraud prevented; recommend changes with evidence.
• Detection and monitoring: turn recurring forensics into scheduled queries, dashboards and alerts so attacks are caught in hours, not after the provider invoice.
• Engineering hand-off: give backend engineers precise, ready-to-implement rule proposals so they stay focused on platform delivery.
• Knowledge transfer: document playbooks and coach our analytics engineer so capability stays in the team.
