Our Fortune 500 client is seeking a Software Engineer II. 

Responsibilities

• Author, maintain, and optimize fraud rules and policies across our real-time fraud decisioning engines to protect customers from account takeover (ATO) and other fraud — this is the core of the role.
• Contribute significantly to the backend services in the fraud-prevention stack: design and implement features, API changes, and integrations; make production code changes; and help improve their reliability, performance, and quality — not just their rules.
• Use AI coding tools as a core part of your workflow (Claude Code, Cursor, Codex) to accelerate both rule authoring and service development — generating, refactoring, and validating rule sets, tests, and service code, always with human review and testing.
• Translate policy and analytics requirements into precise, testable rule logic — tuning thresholds, fraud signals, and link-analysis weights to raise fraud-catch precision while reducing friction for legitimate customers.
• Test changes end-to-end before release using pre-release testing and artifact-deployment tooling, and manage safe production rollouts — including silent/shadow-mode validation and change-request approvals.
• Contribute to engineering quality across the stack: design docs, code reviews, automated tests, CI/CD, and observability.
• Support monitoring, on-call, and rapid issue resolution in production, using observability dashboards to track service health, rule performance, latency, and match rates.
• Collaborate closely with Policy, Analytics, Data Science, and Product partners to respond to emerging fraud attacks and continuously improve detection coverage.

• 2+ years of professional software engineering experience building and contributing to backend services (SWE2 level).
• Proficiency in a server-side language, especially Java (our primary stack); Python or Node.js also valuable.
• Solid experience with RESTful API design and building/maintaining API integrations.
• Experience with database technologies (relational and/or NoSQL).
• Experience with a server framework such as Spring MVC (preferred), Express, or Django.
• Hands-on experience contributing to a production service — production-quality code and tests, deployment, and on-call.
• Proficiency with AI coding tools (Claude Code, Cursor, Codex, etc.) and the judgment to use them effectively while validating their output.
• Solid grasp of Agile development, object-oriented design, and engineering best practices.
• Strong communication and collaboration skills across engineering, policy, and analytics partners.
• Eagerness to learn and adapt in a dynamic, fast-moving environment.
