Gusto is seeking a Senior Fraud Investigations Analyst to independently conduct complex end-to-end fraud investigations involving account takeover, business email compromise, identity theft, payment fraud, and emerging typologies.
The role involves using investigative expertise, open-source intelligence, internal data, and AI-enabled tools to identify root causes, assess risk, and document investigative findings.
Analysts handle complex fact patterns, sophisticated social engineering schemes, and evolving attack vectors while balancing customer impact and risk mitigation.

Independently analyze account activity, transactional behavior, authentication data, customer communications, and external intelligence sources to surface fraud indicators and build well-supported investigative narratives.
Synthesize investigative findings into clear case narratives and prepare Unusual Activity Referrals (UARs) for Financial Crime Compliance partners when appropriate; escalate high-risk events with sound, risk-based remediation recommendations.
Support customers impacted by fraud and coordinate with external banking partners on fund recovery efforts, including Letters of Indemnity.
Leverage AI-enabled tools to accelerate alert triage, issue spotting, research, evidence gathering and documentation, while critically validating AI-generated outputs for accuracy and compliance with Gusto's AI policies.
Collaborate with Risk, Compliance, Product, Engineering, and Data Science to surface emerging threats, close control gaps, and improve investigative tooling and AI-assisted workflows.
Mentor junior analysts on fraud typology identification, evidence gathering, and case narrative quality through case reviews and structured feedback.

5+ years of fraud investigations, fraud detection, or similarly complex investigative work within a financial institution, FinTech, payment processor, or regulated environment.
Strong investigative writing and analytical skills with the ability to document complex fact patterns, develop defensible narratives, and assess risk across ambiguous scenarios.
Experience across fraud typologies including account takeover, business email compromise, identity theft, payment fraud, and social engineering.
Sound investigative judgment with the ability to manage multiple investigations simultaneously, make risk-based recommendations under pressure, and communicate findings with empathy and clarity to customers, external institutions, and cross-functional stakeholders.
Experience using AI-enabled tools in day-to-day investigative workflows and the ability to critically evaluate AI-generated outputs for accuracy, completeness, and alignment with investigative standards.
Experience mentoring or providing structured feedback to junior investigators.

Certified Fraud Examiner (CFE), CAMS, or other relevant financial crime certifications are a plus.
