About the Role

Navan is building the next generation of intelligent travel experiences, where loyalty, personalization, and AI agents help travelers make better decisions before, during, and after every trip. As a Senior Software Engineer, AI on the Loyalty Wallet team, you’ll build agentic product experiences that understand a traveler’s loyalty programs, surface useful insights, and safely help users manage their memberships through Navan Edge.

Responsibilities

Design and develop agentic workflows that help users view, understand, connect, and manage their loyalty programs through chat, wallet surfaces, and personalized recommendations.
Build reliable LLM-powered flows with structured outputs, tool calling, guardrails, human confirmation, evals, and monitoring for real customer-facing use cases.
Create and maintain scenario tests, adversarial evals, prompt/tool contracts, and quality metrics that ensure agents behave safely around loyalty data, PII, financial guidance, and unsupported requests.
Work across frontend, backend, and AI orchestration layers, including wallet APIs, streaming chat experiences, UI components, data services, and ML/LLM workflows.
Transform loyalty balances, tier progress, membership data, connected email signals, and trip context into useful recommendations and next-best actions.
Partner closely with product, design, backend, data, and platform teams to ship polished, measurable customer experiences.
Champion maintainable code, thoughtful abstractions, strong tests, observability, documentation, and operational ownership.

Requirements

6+ years of software engineering experience building production systems, with meaningful hands-on experience in AI, LLM, agent, workflow, or ML-powered products.
Experience building agentic systems, tool-calling workflows, RAG-like systems, structured LLM outputs, eval pipelines, or AI assistants in production.
Strong engineering fundamentals in TypeScript/Node.js, Java, Python, or similar backend/product engineering stacks.
Experience with distributed systems, APIs, async workflows, caching, observability, and production debugging.
Comfort working with AI safety patterns such as guardrails, HITL confirmation, deterministic tool boundaries, hallucination prevention, and PII-sensitive workflows.
Product mindset and ability to translate ambiguous user needs into robust, user-facing experiences.
Strong ownership mentality, with the ability to ship, measure, iterate, and support features after release.
Experience with travel, loyalty programs, personalization, fintech, or consumer data products is a strong plus.
Bachelor’s or Master’s degree in Computer Science, Engineering, or related field, or equivalent hands-on experience.
