We're looking for a Senior Site Reliability Engineer to embed with a fast-growing AI developer platform company. You'll help their customers run the platform on their own infrastructure: deploying it, keeping it healthy at scale, and making upgrades boring. This role suits someone who has run stateful, self-hosted software in Kubernetes for demanding customers and wants to point that experience at agentic AI.

Key Responsibilities:

Self-Hosted Platform Reliability

• Deploy, upgrade, and operate a containerized AI platform in customer-owned Kubernetes environments using Helm and GitOps (ArgoCD)
• Own the health of stateful backing services in-cluster, including Postgres, Redis, and ClickHouse
• Troubleshoot deployments across varied customer setups, including private networking, air-gapped, and regulated environments
• Turn recurring customer issues into better Helm charts, runbooks, and documentation

Site Reliability Engineering

• Define and track SLIs and SLOs for self-hosted deployments
• Lead incident response and blameless post-mortems
• Do capacity planning and performance tuning for high-volume trace and event data
• Reduce toil through automation

Infrastructure & Cloud

• Build and maintain infrastructure with Terraform across AWS, GCP, and Azure (EKS, GKE, AKS)
• Build CI/CD pipelines that test upgrade paths and catch regressions before customers do
• Apply security best practices: secrets management, RBAC, network policy, SSO

Required Qualifications:

• 6+ years in SRE, platform, or infrastructure engineering
• Deep hands-on experience with Kubernetes and Helm in production
• Experience with GitOps tooling (ArgoCD or Flux)
• Experience operating stateful services in Kubernetes (Postgres, Redis, ClickHouse, Kafka, or similar)
• Proficiency with Terraform or similar IaC tools
• Experience with at least one major cloud (AWS, GCP, or Azure) and its managed Kubernetes service
• Solid scripting and automation skills (Python, Go, or Bash)
• Comfortable working directly with customers to debug their environments

Preferred Qualifications (Exceptional Candidates):

• Experience supporting self-hosted or on-prem deployments of a commercial software product
• Experience with air-gapped or regulated environments (FedRAMP, HIPAA, SOC 2)
• Familiarity with observability tooling (OpenTelemetry, Prometheus, Grafana, Datadog, Honeycomb)
• Exposure to LLM applications, agent frameworks, or LLM observability and evaluation tools

What Sets Exceptional Candidates Apart:

• You've written or maintained Helm charts that other teams depend on
• You've scaled ClickHouse or another analytical database under heavy ingest
• Contributions to open-source infrastructure or AI tooling
• Strong technical writing; your runbooks get used
