Sr. Backend Software Engineer, Fraud Risk Platform
Navan is seeking a Senior Backend Software Engineer to join our Fraud Strategy team and help build a scalable, extensible risk platform to mitigate fraud across our travel business. This engineer will be embedded within the business unit and will partner directly with data scientists and fraud strategy leads to create robust, real-time fraud mitigation solutions that protect both Navan and its customers.
In this role, you will lead the design and development of risk-centric services spanning onboarding, booking, and post-booking activities such as chargebacks and dispute management. Your work will power real-time decision engines, including third-party vendor integrations, feedback loops into machine learning models, and manual review tools that close the fraud detection and prevention lifecycle.
Key responsibilities include architecting and building extensible and scalable microservices to support real-time fraud detection and mitigation across the onboarding and booking flows for travel customers. You will work closely with Fraud Strategy Data Scientists to identify data needs, enabling real-time data ingestion and transformation of real-time and offline signals into the risk engine. Additionally, you will develop integrations with third-party fraud vendors, ensuring their signals are correctly ingested and processed in the risk platform.
The ideal candidate will have 6+ years of experience as a backend software engineer with strong backend architecture skills. Deep experience with Java, Spring Boot, and microservices architecture is essential. Familiarity with cloud-native infrastructure, especially AWS, and containerized services using Docker and Kubernetes is required. Strong understanding of CI/CD best practices and experience with GitHub Actions (or similar), deployment pipelines, and observability tools are also important.
Navan offers a competitive salary range of $120,000 to $150,000 annually, commensurate with experience. Benefits include comprehensive health insurance, a 401(k) plan with company matching, generous paid time off, and opportunities for professional development and growth within the company.
At Navan, we foster a collaborative and innovative culture where team members are encouraged to take ownership of projects and contribute to the company's success. We offer opportunities for career advancement and the chance to work on impactful projects that shape the future of travel and expense management.
