About the Job

Requirements

At least 6 years of software engineering experience building production systems, with meaningful hands-on experience in AI, large language model, agent, workflow, or machine-learning-powered products.
Experience building agentic systems, tool-calling workflows, retrieval-augmented generation-like systems, structured large language model outputs, evaluation pipelines, or production AI assistants.
Strong engineering fundamentals in TypeScript/Node.js, Java, Python, or similar backend/product engineering stacks.
Experience with distributed systems, application programming interfaces, asynchronous workflows, caching, observability, and production debugging.
Comfort working with AI safety patterns such as guardrails, human-in-the-loop confirmation, deterministic tool boundaries, hallucination prevention, and personally identifiable information-sensitive workflows.
A 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.
A bachelor's or master's degree in Computer Science, Engineering, or a related field, or equivalent hands-on experience.

Responsibilities

Design and develop agentic workflows that help users view, understand, connect, and manage loyalty programs through chat, wallet surfaces, and personalized recommendations.
Build reliable large language model-powered flows with structured outputs, tool calling, guardrails, human confirmation, evaluations, and monitoring for real customer-facing use cases.
Create and maintain scenario tests, adversarial evaluations, prompt/tool contracts, and quality metrics to ensure agents behave safely around loyalty data, personally identifiable information, financial guidance, and unsupported requests.
Work across frontend, backend, and AI orchestration layers, including wallet application programming interfaces, streaming chat experiences, user-interface components, data services, and machine-learning/large language model workflows.
Help transform loyalty balances, tier progress, membership data, connected email signals, and trip context into useful recommendations and next-best actions.
Partner 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.

Desired Qualifications

Experience with travel, loyalty programs, personalization, fintech, or consumer data products is a strong plus.

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.

Develop Production AI Systems: Build reliable LLM-powered flows with structured outputs, tool calling, guardrails, human confirmation, evals, and monitoring for real customer-facing use cases.
Own Agent and Workflow Quality: 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.
Integrate Across the Stack: Work across frontend, backend, and AI orchestration layers, including wallet APIs, streaming chat experiences, UI components, data services, and ML/LLM workflows.
Turn Data Into Personalization: Help transform loyalty balances, tier progress, membership data, connected email signals, and trip context into useful recommendations and next-best actions.
Collaborate Cross-Functionally: Partner closely with product, design, backend, data, and platform teams to ship polished, measurable customer experiences.
Raise the Engineering Bar: Champion maintainable code, thoughtful abstractions, strong tests, observability, documentation, and operational ownership.

What We’re Looking For:

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.
