Job Description

Based onsite in Bentonville, Arkansas, Walmart invites a Senior Data Analyst to lead the fraud-detection effort within its Last Mile Delivery program. You will act as the lead architect for building, scaling, and optimizing fraud-detection capabilities across Walmart’s expansive data ecosystems, developing risk-signal logic and end-to-end SQL and Python pipelines, and presenting fraud strategies to senior leadership to align the roadmap with global business goals.

Responsibilities

Scale pattern recognition by analyzing user behavior and platform interactions at scale to identify unusual activity, suspicious accounts, and emerging fraud vectors.
Core analytic execution using segmentation, trend analysis, anomaly detection, and correlation testing to reveal sophisticated fraud patterns across large, complex datasets.
Risk signal synthesis through the combination of data points such as GPS movement, device details, and behavioral metadata to produce high-fidelity risk assessments.
Contextual intelligence that incorporates real-world factors, including cultural, social, and environmental context, to capture nuances automated systems might miss.
Signal engineering to design and refine fraud indicators, including measurable behaviors, thresholds, and composite signals for continuous monitoring via models and dashboards.
Hypothesis validation that identifies fraud motivations and opportunities, transforming ideas into testable data signals and validation frameworks.
Logic optimization by stress-testing queries against legitimate user scenarios to refine logic, thresholds, and exclusion rules, reducing false positives.
Strategic enhancements through structured feedback and technical business requirements to drive new fraud signals and detection-tool improvements.
Audit-ready documentation, maintaining structured investigation records that document every step from detection to deactivation.
External intelligence integration using OSINT to supplement internal data, confirm identities, and uncover external fraud clues or networks.
Defensible reporting with clear technical documentation designed to withstand audits or legal scrutiny.
Adversarial prototyping to anticipate exploits by thinking like a bad actor and identifying vulnerabilities to stay ahead of evolving fraud tactics.
Cross-functional insight delivery to Product, Legal, Compliance, Engineering, and Care Operations, informing tooling improvements and policy updates.
Strategic decision support through deep operational context that guides broader fraud-prevention strategies and product design decisions.
Programmatic gap analysis that summarizes operational findings, QA trends, and SOP gaps to drive ongoing program updates.
Compliance and audit governance, overseeing technical and operational documentation to ensure audit readiness and global compliance adherence.
