What you'll do

Working in the Seller Risk organization, you will help prevent bad actors from entering the ecosystem and monitor seller behavior throughout the lifecycle to maintain a safe, high-quality Marketplace.

Walmart Marketplace is one of the fastest-growing U.S. e-commerce platforms. As we scale, protecting our customers, sellers, and brand through proactive risk management is essential. The Seller Risk organization helps prevent bad actors from entering the ecosystem and monitors seller behavior throughout the lifecycle to maintain a safe, high quality Marketplace.

The Emerging Threats Analyst II supports Walmart Marketplace’s Emerging Threats program by identifying, analyzing, and helping mitigate new and evolving seller risks across onboarding, identity verification, and ongoing seller lifecycle monitoring. You will partner closely with the Director of Emerging Threats to surface early risk signals, investigate patterns, and translate insights into scalable detection and enforcement strategies.

• Detect emerging seller threats by monitoring onboarding and lifecycle signals to identify new fraud vectors and abuse trends (e.g., identity risk, behavioral anomalies, misrepresentation, coordinated networks, counterfeit risk, prohibited/restricted goods).
• Conduct investigations and deep-dive analyses to determine root cause, scope, and impact of suspicious activity; document findings and support escalations as needed.
• Develop and maintain early‑warning signals and risk frameworks across the full seller lifecycle (pre‑onboarding, onboarding, post‑onboarding monitoring).
• Partner with Data Science and Engineering to translate threat patterns into detection logic (models/heuristics), automation, dashboards, and tooling; help define and monitor performance metrics.
• Collaborate with Trust & Safety, Compliance, and Risk Oversight partners to support governance, consistent triage, and response processes.
• Create recurring and ad‑hoc threat intelligence briefs summarizing trend shifts, emerging patterns, risk tradeoffs, and recommended mitigations for leadership audiences.
• Drive continuous improvement by turning investigation outcomes into playbook enhancements, policy feedback, and tooling recommendations.
• Support cross‑functional testing and rollout of interventions (e.g., step‑up verification, monitoring thresholds, enforcement controls) and measure impact.

• 3+ years of experience in marketplace risk, fraud analysis, trust & safety, identity risk, payments risk, compliance operations, investigations, or related analytical functions.
• Strong analytical problem‑solving skills and comfort working with ambiguous signals and evolving threat landscapes.
• Experience analyzing large datasets and translating insights into operational recommendations that reduce risk and improve detection outcomes.
• Excellent written and verbal communication skills with the ability to summarize complex issues clearly for cross‑functional stakeholders.
• Demonstrated ability to collaborate effectively across teams in a fast‑paced environment.

• Experience supporting Seller Risk programs in a large‑scale e‑commerce marketplace environment.
• Familiarity with machine learning‑driven risk models and analyst contributions (feature ideation, labeling/ground truth, threshold tradeoffs, monitoring).
• Knowledge of threat intelligence methods, including trend monitoring, actor typologies, and network‑based behaviors.
• Exposure to global risk considerations and evolving regulatory or compliance constraints.

• SQL and/or BI tools for analysis and dashboarding; ability to partner with technical teams on instrumentation and automation.
• Strong Excel/Sheets skills; ability to build repeatable monitoring views and operational reporting.
• Bonus:
  Python/R, anomaly detection concepts, graph/network analysis, experimentation measurement.

You’ll contribute to work that protects customers, sellers, and the Walmart brand—helping the Emerging Threats team stay ahead of fraud and abuse patterns at Marketplace scale.
