Scale the infrastructure to support millions to billions of concurrent sandboxes.

Construct a comprehensive observability stack beginning at the virtual machine kernel level.

Requirements

Minimum of 5 years of professional experience building complex distributed systems.

Proven track record operating infrastructure at significant scale, such as 100K+ RPS, multi-region setups, and petabyte-scale data.

Deep expertise in Linux internals, including kernel-level debugging with eBPF, CPU scheduling, memory management, and cgroups v1 versus v2.

Practical experience with VM hypervisors such as Firecracker, QEMU, or KVM, along with an understanding of virtio, hypercalls, and nested virtualization.

Strong systems programming skills in languages like Rust or C/C++, with the ability to write performance-critical code utilizing lock-free data structures and memory-mapped files.

Hands-on production orchestration experience using Kubernetes, Nomad, or custom systems, including handling bin-packing algorithms and noisy neighbor problems.

Obsession with performance, including shaving milliseconds off hot paths, profiling production systems under load, and optimizing p99 latency.

Solid networking knowledge encompassing L4/L7 load balancing, network namespaces, iptables/nftables, and secure multi-tenant isolation topologies.

Genuine excitement for open-source software, transparent infrastructure, and community documentation.
