Member of Technical Staff (Infrastructure)

Skills

About the Role

You will build and operate the distributed infrastructure that runs millions of browser sessions for AI agents. You will optimize VM and Linux kernel performance, implement multi tenant isolation, and design global orchestration and scheduling to achieve sub second session startup. You will debug kernel and networking issues, add kernel level observability (including eBPF and distributed profiling), and deploy reliable multi cloud infrastructure and developer primitives for browser automation.

Requirements

• 5+ years operating distributed systems handling thousands of requests per second
• Deep Linux knowledge including kernel debugging eBPF and syscall optimization
• Experience with resource isolation multi tenancy and security boundaries
• Network engineering fundamentals and production packet loss debugging
• Production experience with VM hypervisors such as Firecracker QEMU or KVM
• Experience building or operating orchestration systems (Kubernetes Nomad or custom)
• Familiarity with observability tooling and distributed tracing

Responsibilities

• Build globally distributed VM orchestration with sub second startup
• Design and implement multi tenant isolation architecture for untrusted code
• Perform kernel level observability including eBPF tracing and distributed profiling
• Optimize VM and Linux kernel performance and syscall behavior
• Implement high performance networking features such as anycast routing and cross region failover
• Deliver multi cloud deployment infrastructure using Pulumi for AWS GCP and Azure
• Develop developer primitives and tooling for reliable browser automation
• Contribute to open source tooling and infrastructure projects

Benefits

• Founding engineer equity (employee #5-7)
• Health dental vision for you and family
• Regular team events and off sites
• Brand new laptop setup
• Gym membership subsidies
