Weāre 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 code sandboxes (isolated remote containers) that we manage. Weāre revenueāgenerating and backed by AI Grant, YCombinator, Bessemer Venture Partners and the founders from Vercel, Notion, Perplexity, Palantir, Replit, Zapier, Intercom, and Dropbox.
The Role
Build and scale the codeāexecution sandboxes that power Julius across cloud environments (AWS and GCP). We orchestrate 500k+ containers/month and growing. Youāll own reliability, performance, and security for multiātenant compute.
What Youāll Do
Design and operate secure, multiātenant container infrastructure with fast startup and smart autoscaling.
Ship 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 fairāuse and rateālimiting 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, multiātenant systems.
Nice to Have
gVisor/Kata/Firecracker; Cilium/eBPF; GPU scheduling; serverless autoscaling (KEDA/Knative/Karpenter).
Youāve built an AI side project and enjoy tinkering with LLMs.
Why Julius
Small, senior team; massive impact surface; hard infra problems at meaningful scale.
