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.
