AI Expense Report Anomaly Detection Engineer

Cora Bianchi

Full-time · Job · New_York

About the role

Finance still catches duplicate expense claims manually, three weeks after reimbursement already went out. By then the money's gone and getting it back is its own process. We want to catch it before approval, not after. You'll build an anomaly detection layer on top of our existing invoice and receipt extraction pipeline, flagging duplicate submissions, out-of-policy amounts, and unusual vendor patterns before an expense report gets approved. Small team, fast shipping. You'll have your first detection rules in production within the first month, then iterate based on what finance teams actually flag as false positives.

Responsibilities

  • Build anomaly detection rules for duplicate and out-of-policy expense claims
  • Integrate detection into the existing receipt extraction pipeline
  • Reduce false positives based on direct finance team feedback
  • Ship initial detection rules within the first month
  • Monitor detection accuracy as new expense categories are added

Requirements

  • Comfortable with Python and pandas for anomaly detection logic
  • Basic scikit-learn experience for classification models
  • SQL fluency for querying expense and vendor data
  • Entry-level friendly, mentorship provided by senior document processing engineers

Benefits

  • Fully remote position
  • Health coverage from day one
  • Mentorship from senior engineers on the document processing team
  • Clear path to mid-level within the first year
  • Small team, visible impact on every shipped feature
