Navier AI jobs

Backend Engineer San Francisco About Navier AI Navier AI is building the first autonomous engineering agents. AI systems that can design, simulate, and optimize complex products to achieve breakthrough levels of performance. Our mission is to enable engineers to move beyond today's slow, manual design cycles by providing agents that reason about physics, explore design trade-offs, and generate high-performance solutions across aerospace, automotive, and advanced manufacturing. We're backed by top-tier investors and work directly with industry leaders to deploy AI-native tools that go far beyond today's design automation. Role Overview We're hiring a Backend Engineer to help build the infrastructure behind our autonomous engineering agents. You'll work across model serving, simulation orchestration, multi-agent coordination, and developer-facing APIs. This role is critical to delivering fast, reliable, and scalable systems that engineers can trust in production design environments. Responsibilities - Own core backend systems for serving AI agents and managing their compute, data, and model coordination - Design and implement APIs that expose agent functionality-simulation control, CAD operations, optimization workflows-to internal tools and customer integrations - Build secure, scalable infrastructure for multi-agent orchestration, including support for containerized workloads, caching, and distributed compute - Collaborate closely with ML, frontend, and simulation engineers to create a cohesive, performant product experience - Integrate external tools such as CAD software, simulation backends (e.g., OpenFOAM), and data stores into our pipeline - Support agent development workflows, including tooling for versioning, introspection, and reproducibility - Contribute to infrastructure decisions that will shape the technical foundation of our platform

Senior AI Operations (AI Ops) Engineer Palo Alto, CA At Navan, we aren't building a single, generic chatbot. We are building a Composable AI Microservice Architecture , a swarm of hundreds of hyper-specialized AI services, each meticulously "programmed" to solve small, focused tasks with high precision. This fleet powers Ava , our AI support engine, and a suite of cutting-edge generative tools for travel and expense management. As a Senior AI Operations (AI Ops) Engineer , you are the architect of the platform that makes this scale possible. You will move beyond traditional MLOps to manage a "factory" of Language Models. Your challenge is one of orchestration and standardization, ensuring that every service in the swarm meets a rigorous bar for quality, reliability, and cost-efficiency. What You'll Do Orchestrate the AI Fleet: Build and own the runtime environment for 100+ specialized AI services. Manage model routing, context versioning, and standardized memory/history stores. High-Density Inference Optimization: Design and implement SageMaker Multi-Model Endpoints (MME) and Inference Components to serve multiple tuned SLMs per GPU, maximizing hardware utilization while minimizing latency. Deterministic Service Excellence: Treat reliability as a layered engineering problem. Build deterministic "shells" around probabilistic LM outputs, prioritizing data-layer validation and strict serialization. Automated Evaluation & Observability: Implement "LLM-as-a-judge" patterns and automated benchmarking to detect semantic drift and hallucinations across the fleet before they impact the user. Standardize the Workflow: Obsess over building reusable patterns and Terraform-based infrastructure that eliminate "snowflake" configurations, allowing us to deploy new specialized AI tasks in minutes.

Staff Product Manager, AI Palo Alto, CA At Navan, “It's all about the user. All of them.” We're passionate about creating seamless, personalized travel experiences for business travelers around the globe. We are looking for an AI Product Manager for our Navan Edge team in Palo Alto. Your mission is to evolve Navan Edge into a proactive AI travel agent . You won't just be building features; you'll be designing the autonomous systems that anticipate traveler needs before they even arise. What You'll Do Architect Agentic Experiences: Design and scale AI-driven "agentic" workflows that handle end-to-end travel logistics Define the AI Strategy: Lead the vision for how Generative AI, RAG, and personalized LLM fine-tuning can create a "hyper-personalized" experience for every traveler. End-to-End Life Cycle Orchestration: Map the traveler's journey, Pre-trip, During-trip , and Post-trip into a single, invisible AI thread. Predictive Problem Solving: Define the logic for "Ghost-Concierge" moments, where the AI detects a missed connection and has three alternative options ready for a one-tap confirmation before the traveler even lands. Data-Driven Navigation: Use data not just for reporting, but to identify patterns where AI can reduce "travel friction." You'll define KPIs around autonomous task completion and AI-to-human handoff efficiency . Cross-Functional Orchestration: Partner with AI Research and ML Engineering to balance model performance with latency and cost. Collaborate with Design to rethink how to merge conversation with UI components. Champion Trust & Safety: Ensure that AI-driven travel recommendations are unbiased, secure, and compliant with global data privacy standards.
