Fraud Strategist - Login and Auth

Full-time
The Role
We are searching for a Fraud Strategist, Login and Auth to own the perimeter of the SoFi platform. This is a sophisticated role at the intersection of adversarial threat intelligence, device forensics, and real-time decisioning. You will design fraud strategy across login, password reset, MFA, step-up, and high-risk session events, calibrated against the full spectrum of perimeter threats: account takeover (ATO), authorized scams, credential stuffing, MFA bombing, OTP interception, SIM swap, adversary-in-the-middle phishing, and emulator-driven bot traffic.
What You'll Do
- Owning the end-to-end login risk strategy across web and mobile authentication surfaces: signal selection, rule construction, threshold tuning, champion/challenger lifecycle, and rule-level loss attribution.
- Architecting perimeter-threat defense covering ATO, scam interception (authorized push payment, remote access, impostor, investment), MFA bombing, OTP interception, SIM swap, and adversary-in-the-middle phishing.
- Translate live campaign telemetry into production rule changes within hours.
- Driving device forensics at depth: device fingerprinting, emulator and VM detection, jailbreak and root signals, residential-proxy detection, and entity-level device-graph analysis to surface coordinated abuse hidden under individually clean sessions.
- Designing step-up authentication, account recovery, and high-risk transaction decisioning that synthesizes device, behavioral, network, and credential-risk signals into a single decision, with explicit FPR budgets per surface.
- Leading 3DS, CNP, and tokenization risk decisioning for card-not-present transactions, coordinating with issuer processing and network rules to optimize approval rate without ceding losses.
- Partnering with InfoSec threat intel on credential-capture campaigns (phishing kits, SEO poisoning, ATO-as-a-service marketplaces) and translating intelligence into rule changes inside the live policy stack.
What You’ll Need
- BA/BS in Statistics, Information Systems, Mathematics, Data Science, or related fields, or equivalent work experience, and 5–8 years of work experience in Fraud Analytics, Authentication Risk, or Adversarial Security Engineering.
- ATO and Scam Defense: Demonstrated track record reducing account takeover and scam losses across banking, card, and crypto surfaces. Comfort across the full kill chain: credential exposure, login compromise, in-session manipulation (remote access, screen share, social engineering), and money movement out.
- Perimeter Threat Fluency: Operational understanding of credential stuffing, MFA bombing, OTP interception, SIM swap, adversary-in-the-middle phishing, residential-proxy abuse, and emulator-driven automation. You can recognize a campaign in flight from telemetry and respond at the policy layer.
- Device Forensics: Hands-on experience with device fingerprinting, emulator and VM detection, jailbreak and root signals, behavioral biometrics, and entity-level device-graph analysis.
- Authentication Stack Depth: Working knowledge of FIDO2/passkeys, OAuth/OIDC, 3DS protocol mechanics, tokenization, and the trade-offs between approval rate and chargeback exposure on CNP flows.
- Balance Friction and Growth: Deep mastery of evaluating trade-offs between fraud mitigation and UX. You can articulate why a 50 bps lift in challenge rate is or is not worth the loss avoidance, with the data to back it.
- Architect Scalable Data Systems: Expert-level SQL/Python skills used to build automated, high-volume data architectures and statistical models that serve as the foundation for global risk detection.
- Drive Strategic Influence: A proactive operator who uses cross-functional persuasion to align EPD, IAM, InfoSec, and Fraud Ops on policy changes, and owns end-to-end execution in fluid environments.
- Founders’ Mentality: You need to have a positive, proactive attitude, being able to identify problems, raise proposals, and be an advocate of your initiatives.
