Software Engineer II

New York, New YorkHybridContractUp to $69.8/hrTitle: Software Engineer IIDescription: • 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.Skills: Required 2 years of professional software engineering experience building and contributing to backend services SWE2 level.
