Title: Software Engineer II (Backend Java)
Location: New York NY-10003
Pay rate: $65.00 - 68/hour DOE
Duration:  12+Months (Possibility of extension)
 
Duties:
  • 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.
 
Preferred Qualifications:
  • 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.
 
Education Required
Bachelor’s degree in an IT-related or Engineering field.
