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 revenue‑generating and backed by AI Grant and founders from Vercel, Notion, Perplexity, Palantir, Replit, Zapier, Intercom, and Dropbox.

The Role

Build and scale the code‑execution platform that powers Julius—across cloud and on‑prem environments. We orchestrate 500k+ containers/month and growing. You’ll own reliability, performance, and security for multi‑tenant compute.

What You’ll Do

  • Design and operate secure, multi‑tenant container infrastructure with fast startup and smart autoscaling.

  • Ship on‑prem/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 fair‑use and rate‑limiting 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, multi‑tenant systems.

Nice to Have

  • gVisor/Kata/Firecracker; Cilium/eBPF; GPU scheduling; serverless autoscaling (KEDA/Knative/Karpenter).

  • Delivered on‑prem or air‑gapped 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.
