About the Job

Requirements

  • At least 8 years of experience in backend software development.
  • At least 3 years of experience in AI architecture with demonstrated organization-wide impact.
  • Strong experience designing and delivering production software systems, with substantial work on AI/ML-powered products or services.
  • A track record of setting technical direction across teams and influencing decisions through evidence and collaboration.
  • Practical understanding of LLM applications, including retrieval and context construction, tool use, agent patterns, model selection, and failure handling.
  • Experience defining quality expectations and building evaluations for AI behavior, and ability to connect offline evaluations to production outcomes.
  • Sound judgment about where AI is appropriate and when a simpler deterministic approach is better.
  • Experience with production concerns such as observability, privacy and security, reliability, cost, latency, and safe human escalation.
  • Clear communication across engineering, product, and executive audiences, with a builder's mindset and comfort prototyping and reviewing implementation.

Responsibilities

  • Set AI architecture direction by defining reference architectures and design principles for AI services, agents, model integrations, data and context flows, tools, and human review, and make trade-offs among quality, autonomy, reliability, latency, cost, and complexity.
  • Build the evaluation discipline by helping teams define expected behavior and success measures, designing representative datasets and evaluation methods, writing and maintaining evaluations, establishing regression checks and quality thresholds, and using results to prioritize improvements.
  • Guide production readiness by shaping shared practices for tracing and observability, versioning, monitoring, incident response, privacy, security, and lifecycle management of AI systems.
  • Enable teams to ship by creating reusable patterns, reference implementations, and practical guidance; coach engineers through architecture reviews; and help teams move valuable work from prototype to production.
  • Connect architecture to outcomes by partnering with product, operations, and domain teams to identify workflow needs and measure whether AI improves completion, quality, time, or other agreed outcomes.
  • Stay close to implementation by prototyping high-risk or foundational designs, reviewing critical implementations, and using production evidence to refine architecture.
  • Track the evolving ecosystem by evaluating models, agent runtimes, orchestration approaches, and evaluation tooling against requirements, and recommending adoption based on evidence.

Desired Qualifications

  • Establishing shared AI platforms, service patterns, or architecture standards across multiple teams.
  • Creating evaluation datasets, test harnesses, regression suites, or quality dashboards for LLM or agent systems.
  • Operating AI products with measurable user or business outcomes.
  • Working with cloud AI platforms, model APIs, agent frameworks, tracing/evaluation tools, and data platforms.

About the Company

Navan

Runs business travel and expense management

Navan runs a business travel and expense platform for companies, combining trip booking with tools that let finance teams track and control employee spending. Travelers search flights, hotels, trains, and rental cars through its website or mobile app, while administrators set booking limits and approval rules. Its expense software captures receipts, categorizes purchases, reimburses employees, and sends records to accounting systems, keeping travel and finance work in the same service. The company earns usage fees from its travel and payments business alongside software subscriptions. Navan was founded in 2015 and is headquartered in Palo Alto, California.
