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 build the responsive frontend interfaces for our Admin and User portals, while simultaneously evolving the robust Java/Spring Boot backend services that power them.
- Build Enterprise-Grade Workflows: Create intuitive UIs and powerful backend engines for complex business domains, such as configuring travel policies, visualizing approval chains, and managing user roles/permissions.
- Build Data-Driven Services: Build scalable APIs and data services that manage high volumes of data, power reporting features, and enable seamless integrations.
- Own Features End-to-End: Take technical ownership of a problem domain, facilitating the design, development, and launch of key features and microservices 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.
What We’re Looking For:
- 4+ years of experience in software development, building complex systems for SaaS products or consumer-facing web applications in a fast-paced environment.
- Frontend Expertise: Deep, hands-on experience (4+ years) in frontend development using modern frameworks like React, Angular, or Vue, along with deep proficiency in TypeScript. You should be highly skilled in managing complex application state and optimizing rendering performance.
- Backend Proficiency: Solid experience with backend development using Java and Spring Boot, including hands-on experience with databases (SQL and/or NoSQL), data modeling, and query optimization to support your frontend features.
- Global Mindset: Demonstrated experience with and a strong passion for web accessibility (A11y) and localization (l10n) best practices to serve a diverse, global user base.
- Systems Architecture: Experience designing and implementing scalable applications across microservices, distributed systems, and cloud platforms like AWS.
- Collaborative Ownership: Demonstrates strong ownership and a collaborative mindset, with clear communication skills and a proven ability to ship production-quality code equipped with robust monitoring and documentation.
- AI-Enabled Workflow: Ability to effectively leverage AI development tools (such as GitHub Copilot, CodeGPT, Claude, and Cursor) to accelerate development and innovate on engineering workflows while maintaining high standards for code quality.
- Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field—or equivalent hands-on experience.
