Why Vectara?

Vectara's RAG and Agentic AI platform helps enterprises deploy AI agents and assistants that are accurate, secure, and explainable. We built the Hughes Hallucination Evaluation Model (HHEM) — #1 on HuggingFace with 5.5M+ downloads, cited in the New York Times and Visual Capitalist — and Mockingbird, a purpose-built LLM optimized for retrieval-augmented generation. Over 100 enterprise customers across high tech, defense, financial services, healthcare, and manufacturing trust our platform in production.

We're a ~50-person team backed by ~$70M in funding, founded by neural information retrieval and distributed systems experts from Google. Alumni of Cloudera, Splunk, MongoDB, and Elastic round out a team building the infrastructure layer for trustworthy enterprise AI.

The Role
You'll own the infrastructure that runs our deploy anywhere platform — from Kubernetes clusters serving ML inference at scale to the CI/CD pipelines, IaC, and observability stack that keep it all reliable. This is a hands-on role: you'll write Helm charts and Terraform one day, debug a Kafka consumer lag issue the next, and ship a backend service feature the day after. You'll deploy across AWS, GCP, and on-premises (including air-gapped environments), and you'll participate in an on-call rotation supporting enterprise customers.

What You’ll Do

• Build and maintain infrastructure-as-code (Terraform, Helm) for our AWS EKS and GCP GKE clusters, plus on-premises deployments (including Tanzu and air-gapped environments).
• Own CI/CD pipelines (GitHub Actions, Bazel, ArgoCD) and drive GitOps adoption.
• Deploy, scale, and optimize ML/NLP inference workloads (vLLM, PyTorch, GPU scheduling with various Kubernetes scalers).
• Build and improve observability: Prometheus, Grafana, Datadog,, and OpenTelemetry.
• Collaborate with Field Engineering to support PoCs and platform deployments in customer cloud VPCs and on-prem environments.
• Contribute to backend services (Java 21, Python, gRPC) and platform features.
• Improve system reliability, scalability, and developer experience across the engineering org.

What You’ll Bring (Required):

• 2+ years in platform engineering, DevOps, SRE, or backend infrastructure roles.
• Strong Kubernetes experience (deployment, debugging, scaling — not just `kubectl apply`).
• Hands-on with infrastructure-as-code: Terraform, Helm, or Pulumi.
• Experience with at least one major cloud provider (AWS preferred; GCP or Azure also valued).
• Proficiency in one or more of: Go, Python, Java. Comfortable reading and contributing to backend codebases.
• Working knowledge of CI/CD systems (GitHub Actions, Bazel, ArgoCD, or similar).
• Solid fundamentals in Linux, networking, and distributed systems.

What Sets You Apart (Preferred)

• Experience deploying or operating ML inference workloads (model serving, GPU scheduling, vLLM, TensorFlow Serving, or similar).
• Familiarity with streaming/messaging systems (Kafka, Pulsar) and data stores (MariaDB/PostgreSQL, Aerospike, ClickHouse, OpenSearch).
• Experience with GitOps workflows (ArgoCD, Flux).
• Exposure to air-gapped or on-premises Kubernetes deployments.
• Background in observability tooling (Prometheus, Grafana, OpenTelemetry, Datadog).
• Experience providing technical support or working directly with enterprise customers on infrastructure issues.
• Comfort with AI-assisted development workflows and managing AI coding agents.

Why Join Now

Vectara is at an inflection point — strong product-market fit with 100+ enterprise customers, fresh leadership with co-founder Tallat Shafaat as CEO, and a platform that's becoming the standard for trustworthy enterprise AI. You'll work alongside pioneers in neural information retrieval, contribute to open-source projects used by millions, and build infrastructure for AI that enterprises actually trust in production. The team is small enough that your work will have an outsized impact.
