Navan is reinventing corporate travel and expense management for millions of users worldwide. As a Fullstack Software Engineer II on the Flights team , you will build and scale the mission-critical web applications and engine that power how users search, book, pay for, and expense flight itineraries in seconds. You will be reporting to the Senior Engineering Manager of Flights Platform. The Flights domain sits at the core of Navan’s platform, combining intuitive, lightning-fast user interfaces with complex global distribution systems, high-throughput search queries, and real-time global transaction processing. We operate at scale, value engineering craftsmanship, and move fast. If you want to own end-to-end features—from pixel-perfect frontend experiences to robust high-availability backend services—and directly impact the travel experience of millions of users daily, this role is for you. What You’ll Do Build End-to-End Features: Own feature delivery across the entire stack—designing modern, responsive user interfaces, defining slick API contracts, and implementing scalable backend business logic. Architect Frontend & Backend Systems: Develop modular, performant web applications using modern JavaScript/TypeScript frameworks while building low-latency REST/GraphQL APIs and microservices. Deliver Pixel-Perfect User Experiences: Collaborate closely with Product Managers and Product Designers to translate complex travel workflows into intuitive, accessible, and high-converting user interfaces. Ensure Fullstack Resiliency & Quality: Take full ownership of code quality by writing unit, integration, and end-to-end tests across the full stack, backed by robust frontend and backend telemetry, alerting, and observability. Optimize Performance: Drive web vitals, state management efficiency, and backend API latency optimizations to ensure users can book and pay within seconds. Elevate Developer Craftsmanship: Participate in design reviews, contribute to shared UI component libraries, and champion fullstack engineering best practices across the team. What We’re Looking For Experience: 3–5 years of professional fullstack software engineering experience, with a track record of building and launching production-grade web applications. Core Fundamentals: Strong computer science foundations (data structures, algorithms, object-oriented design) and a deep understanding of browser runtime behavior, web architecture, and API design. Fullstack Mastery: Hands-on expertise writing clean, maintainable code on both sides of the stack—connecting rich client applications to scalable backend services. End-to-End Ownership: A builder mindset that takes pride in high-quality UX, solid backend logic, comprehensive test coverage, robust observability, and clear technical documentation. Cross-Functional Communication: Excellent, proactive communication skills to bridge technical trade-offs between design, product management, and platform engineering teams. Frontend Tech: Proficiency in modern JavaScript/TypeScript and frameworks like React , Next.js , or similar, alongside modern CSS/HTML and state management libraries. Backend & APIs: Experience with Java , Spring / Spring Boot, along with ORM technologies like Hibernate and relational database design. Cloud & Infrastructure: Hands-on experience deploying and managing applications on AWS within a microservices architecture. Domain Bonus: Prior experience building consumer-facing SaaS applications, checkout/payment flows, or travel technology integrations is a plus.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
