Full Stack Engineer

Navan has transformed the corporate travel, payment, and expense landscape by consistently prioritizing user needs. As a Senior Full Stack Engineer on the Enterprise Team, you will be a technical leader helping to build the "operating system" of our corporate travel platform. Our team owns the critical infrastructure that allows companies to function globally—managing everything from granular travel policies and dynamic approval workflows to user identity and enterprise-grade analytics.

This is a high-impact role where you will bridge the gap between complex backend logic and intuitive user experiences. You will collaborate closely with a talented team of engineers, product managers, and designers to build sophisticated configuration tools, real-time dashboards, and seamless integration flows that empower our customers to manage their travel programs at scale.

What You’ll Do:

• Design, Build, and Evolve: Architect and develop end-to-end features across the stack. You will evolve the robust Java/Spring Boot backend services that power our platform, while building the responsive frontend interfaces for our Admin and User portals.
• Build Enterprise-Grade Workflows: Create powerful backend engines and supporting UIs for complex business domains, such as configuring travel policies, visualizing approval chains, and managing user roles/permissions.
• Build Data-Driven Services: Architect and scale APIs and data services that manage high volumes of data, ensure transactional integrity, and power reporting features and seamless integrations.
• Own Features End-to-End: Take technical ownership of a problem domain, facilitating the design, development, and launch of key microservices and features that have a direct impact on our users.
• Collaborate Across Teams: Work cross-functionally with various engineering, product, and design teams to deliver complex, cross-domain features in a collaborative environment.
• Drive the Vision: Partner with engineering and product leadership to identify, plan, and execute the long-term technical vision for your domain and be a subject matter expert.
• Champion Best Practices: Contribute to a culture of technical excellence by writing high-quality, well-tested code, mentoring other engineers, and advocating for best practices in testing, monitoring, and operational reliability.
