Navan has transformed the corporate travel, payment, and expense landscape by relentlessly prioritizing the user experience. As a Senior Frontend Software Engineer in the Flights group, you will play an essential role in building and scaling Navan’s flagship product—a next-generation flight platform that drives global business growth and gets people where they need to be.

This is a high-scale, highly complex engineering environment where your work will directly impact travelers worldwide. You will solve challenging architectural problems, collaborate with a global team of elite engineers, product managers, and designers, and write code that powers a platform trusted by the world's largest enterprises. If you are passionate about developer experience, system performance, and building flawless user interfaces, this is your place to build.

What You’ll Do

• Own the End-to-End Experience: Drive complex features from inception to launch. Partner closely with product and design to ship impactful features, monitor their real-world impact, and iterate based on data.
• Architect for Scale: Lead application design and implement critical portions of our frontend architecture. You will translate complex business requirements into scalable, high-quality technical frameworks.
• Champion Operational Excellence: Set the gold standard for frontend reliability, performance, and measurability. You will define the team's approach to application performance monitoring (APM) and continuously optimize the user experience.
• Supercharge Developer Velocity: Build and refine internal frameworks and frontend pipelines that drastically improve developer experience (DX), code health, and time-to-ship for the entire engineering organization.
• Mentor and Elevate: Establish credibility quickly through high-quality code and rigorous design reviews. You will mentor fellow engineers on best practices, modern design patterns, and system architecture.
• Bridge the Stack: While this is a frontend-focused role, you will have the autonomy to work full-stack. A strong understanding of backend systems and APIs will allow you to drive holistic, cross-system improvements.

What We’re Looking For

• Deep Experience: 5+ years of dedicated UI/frontend development experience in high-growth, agile environments.
• Technical Mastery: Expert-level proficiency in JavaScript and TypeScript, with strong hands-on experience in modern frontend frameworks, specifically React and Angular.
• System-Level Thinking: A comprehensive understanding of the technical intricacies of large-scale frontend systems, with a sharp eye for identifying and executing architectural improvements.
• Leadership & Influence: A proven track record of driving positive technical change within engineering organizations. You know how to motivate peers, instill technical accountability, and achieve measurable results.
• Collaborative Spirit: A low-ego, high-impact approach to problem-solving. You communicate complex technical concepts clearly to both technical and non-technical stakeholders.
