Job summary

Roblox is seeking a Safety Threat Investigator to manage high-risk investigations end-to-end, from intake to resolution, applying structured methods and evidence-based analysis. You will preserve provenance, escalate when needed, and prepare actionable outcomes for Legal, Safety, and external partners.

You will mentor junior investigators, contribute to playbooks, and help raise standards for documentation and decision-making across the team.

Qualifications

• 4+ years conducting sensitive investigations involving severe safety, abuse, fraud, security, threat, or other high-risk matters.
• Demonstrated ability to independently manage investigations end-to-end, including intake, scoping, evidence development, analysis, findings, recommendations, and follow-through.
• Experience using SQL and/or Python, large datasets, and open-source intelligence in an investigative context.
• Strong investigative judgment and the ability to distinguish facts, inferences, allegations, unknowns, assumptions, and analytical conclusions.

Responsibilities

• Own repeatable, high-sensitivity investigations involving serious safety threats, including child exploitation, violent extremism, organized fraud, compromised accounts, coordinated abuse, and other high-risk matters.
• Apply structured investigative methods, evidence checklists, common templates, and approved data pulls to produce timely and consistent case outcomes.
• Gather, preserve, analyze, and corroborate evidence while maintaining accurate provenance, confidentiality, and auditability.
• Define investigative questions, scope, hypotheses, evidence plans, milestones, risk controls, and exit criteria for sensitive or ambiguous matters.
• Conduct focused account, entity, and timeline linkage as needed, and identify when a case requires deeper attribution, network mapping, or cross-platform investigation.
• Escalate cases to Specialized Investigations when they develop meaningful attribution complexity, broader network risk, external actionability, or a need for deeper synthesis.
• Prepare clear case summaries and standardized downstream work product for partners such as Legal, Safety Intelligence, Trust & Safety Operations, Law Enforcement Operations, or NCMEC, as appropriate.
• Track recurring patterns, operational pain points, and escalation trends, and translate findings into recommendations for Policy, Product, Engineering, Detection, Legal, and Safety Operations.
• Lead or contribute to durable improvements such as investigation playbooks, evidence standards, intake criteria, triage processes, tooling requirements, and quality-review mechanisms.
• Represent Safety Investigations with cross-functional stakeholders, explain and defend investigative decisions, navigate disagreement, and maintain alignment on sensitive matters.
• Mentor investigators, provide constructive feedback on casework, and raise the team’s standards for investigative rigor, documentation, and inclusive collaboration.
• Maintain strong case hygiene, document decisions and approvals, and ensure investigations are closed with clear outcomes, residual-risk ownership, and follow-up actions.
• Deliver rigorous, timely, and consistent outcomes on high-sensitivity investigations.
• Apply sound judgment in triage, lane assignment, escalation, and case closure.
• Improve the team’s investigative methods, operating processes, templates, and quality standards.
• Convert case findings into concrete safety improvements and upstream action.
• Build trust with cross-functional partners and mentor others to strengthen the team’s investigative capability.
