About Julius

We're an applied AI lab building coding agents. Julius executes ~1M lines of code every 36 hours for 1M+ users and has generated 3M+ visualizations. All code runs in isolated remote containers that we manage. We're revenuegenerating and backed by AI Grant and founders from Vercel, Notion, Perplexity, Palantir, Replit, Zapier, Intercom, and Dropbox.

The Role

Build and scale the codeexecution platform that powers Julius-across cloud and onprem environments. We orchestrate 500k+ containers/month and growing. You'll own reliability, performance, and security for multitenant compute.

What You'll Do

• Design and operate secure, multitenant container infrastructure with fast startup and smart autoscaling.
• Ship onprem/private cloud deployments (Helm/Terraform) with SSO, network controls, and audit logging.
• Drive observability (metrics, traces, logs) with clear SLOs; lead incident response.
• Optimize images, scheduling, networking, and cost; build fairuse and ratelimiting controls.

What You Bring

• Production Kubernetes and container internals (Docker/containerd); strong networking fundamentals.
• Cloud (AWS/GCP/Azure) and IaC (Terraform/Helm).
• Monitoring/Logging (Prometheus, Grafana, OpenTelemetry, ELK/Vector).
• Security best practices for containerized, multitenant systems.

Nice to Have

• gVisor/Kata/Firecracker; Cilium/eBPF; GPU scheduling; serverless autoscaling (KEDA/Knative/Karpenter).
• Delivered onprem or airgapped enterprise software.
• You've built an AI side project and enjoy tinkering with LLMs.

Why Julius

Small, senior team; massive impact surface; hard infra problems at meaningful scale.
