Nice to Have * Experience in fraud, risk, identity, authentication, authorization, abuse prevention, or security engineering. * Familiarity with payments rails, card transaction risk, or account security patterns. * Experience building internal tools for operations teams (case management, investigation, enforcement workflows)., Application Programming Interface (API), Authentication, Automation, Budgeting, Campaigns, Card Processing, Case Management, Communication Skills, Cross-Functional, Data Modeling, Debugging Skills, Distributed Computing, Fast Food, Identity Data Management, Incident Response, Instrumentation, Insurance, Machine Tool, Metrics, On Call, Production Systems, Reporting Dashboards, Revenue Growth, Risk, Semantic Reasoner, Software Engineering, System Operations, Systems Engineering, Technical Recruiting, Technical/Engineering Design, User Interface/Experience (UI/UX) ## Description We are hiring a Software Engineer to build systems across Fraud, UIM (User & Identity Management), and Identity. This role sits at the intersection of security, risk decisioning, and product experience. You will help build detection and enforcement capabilities for fraud and account takeover, as well as the identity primitives that power authentication, authorization, and safe account access. This work is deeply cross-functional. You will partner closely with Fraud Ops, Risk Strategy, Security, Product, and Data to ship improvements that are measurable in loss reduction, attack containment, and user experience. What You'll Do * Build and evolve backend services that detect and prevent fraud across multiple surfaces, including account access and money movement. * Develop enforcement and response tooling that enables fast, safe actions such as identity locks, business locks, payment freezes, and other containment levers. * Improve protections against account takeover (ATO), including risk-based step-ups, monitoring, and targeted friction controls (for example "under attack" style controls and MFA surge detection/alerting). * Design and operate high-signal systems with strong observability: metrics, dashboards, alerting, and playbooks for incidents and fraud campaigns. * Partner with UIM/Identity stakeholders to strengthen authentication and identity foundations (roles, permissions, identity state, and related platform primitives). * Drive end-to-end delivery: technical design, implementation, rollout strategy, and iteration based on outcome metrics., Pursuant to the San Francisco Fair Chance Ordinance, we will consider for employment qualified applicants with arrest and conviction records. Beware of recruiting scams: Ramp will only contact you through official @Ramp.com email addresses and will never ask for payment or sensitive personal information during the hiring process. ## Related Videos - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Migrating half a million users to a new payment service provider](https://www.wearedevelopers.com/videos/730-migrating-half-a-million-users-to-a-new-payment-service-provider) - [Modern Data Architectures need Software Engineering](https://www.wearedevelopers.com/videos/1030-modern-data-architectures-need-software-engineering) - [Slopquatting, API Keys, Fun with Fonts, Recruiters vs AI and more - The Best of LIVE 2025 - Part 2](https://www.wearedevelopers.com/videos/1765-slopquatting-api-keys-fun-with-fonts-recruiters-vs-ai-and-more-the-best-of-live-2025-part-2) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) - [Throwing off the burdens of scale in engineering](https://www.wearedevelopers.com/videos/608-throwing-off-the-burdens-of-scale-in-engineering) ## Related Articles - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers)
