Senior Fraud Engineer

You will be our subject matter expert on account takeovers, payment fraud, and platform abuse. You will serve as the crucial escalation point, investigating complex cases that require deep analytical skills. More importantly, you will use the insights from your investigations to tune our detection tools, collaborate with our engineering team to build new detection models, utilize data to identify patterns or trends, and empower our front-line Trust & Safety team to be more effective.

• Investigate Complex Threats: Serve as the primary escalation point for our Trust & Safety team on complex Account Takeover (ATO), payment fraud, and platform abuse cases.
• Master Our Data: Dive deep into our data using Sift, Looker, and direct SQL queries in Athena/Snowflake to uncover patterns, identify root causes, and find evidence of malicious activity.
• Tune and Refine Detections: Take ownership of the effectiveness of our abuse rule sets. You will constantly analyze rule performance, tune them to reduce false positives, and create new rules to catch emerging threats.
• Automate and Scale: Identify opportunities to automate repetitive analytical tasks using scripting (e.g., SQL, Python) and other tools, freeing up time to focus on high-impact strategic work.
• Collaborate and Empower: Act as a key partner to our Trust & Safety team, providing them with training, documentation, and expert guidance. You will also partner closely with our Security Data Engineering to design and build new detection models.
• Drive the Feedback Loop: You will be the engine of our improvement cycle. When you see a gap in our defenses, you will be responsible for defining the requirements for a new rule, model, or data source and seeing it through to implementation.
• Manage Vendor Relationships: Act as the primary technical point of contact for our fraud and security tooling vendors, ensuring we are maximizing their value.

• 5+ years of experience in a fraud, risk, or trust and safety analyst role, preferably within a SaaS or technology company.
• Strong data analysis skills. You must be proficient in writing SQL queries to pull and manipulate data. Experience with data warehouses like Athena or Snowflake is ideal.
• An Investigative Mindset: You are naturally curious, skeptical, and detail-oriented. You know how to form a hypothesis, pull the data to test it, and follow the evidence to a conclusion.
• Excellent Communication and Collaboration Skills: You can clearly explain complex technical concepts to non-technical audiences and enjoy working collaboratively with other teams to solve problems.
• A Bias for Action and Ownership: You are comfortable working in a small team environment and are not afraid to take ownership of a problem from start to finish.

• Experience with data visualization tools like Looker, Tableau, etc.
• Basic scripting skills (e.g., Python) for data analysis or automation.
• Experience in training or mentoring other analysts.
