Meta's container platform runs a large share of the services that power Facebook, Instagram, WhatsApp, Messenger, and Meta's AI products. The Containers team builds and runs the node-level software that starts, isolates, networks, and manages these workloads across a global fleet of millions of machines. We help Meta use its hardware efficiently through multi-tenancy, support new hardware including AI accelerator platforms, and build the next generation of our container runtime. We work closely with Meta's Linux kernel, networking, capacity engineering, and AI infrastructure teams. Many of the problems we solve exist nowhere else at this scale. We're looking for a Technical Lead to set the technical direction for three core areas: resource isolation, container networking, and the long-term evolution of our container runtime. You'll define the multi-year architecture, make key design decisions, mentor a team of systems engineers, stay hands-on in the most critical code, and influence partner teams across the infrastructure organization.

Responsibilities

Set technical strategy and roadmap for container resource isolation, networking, and runtime architecture
Design isolation mechanisms for densely packed multi-tenant hosts that manage contention across CPU, memory, I/O, and network, using cgroup v2 and other kernel primitives
Lead the architecture of container networking across diverse workloads and hardware, including network namespaces, eBPF-based datapaths, and network isolation and policy
Drive the modernization of the container runtime toward a modular, standards-aligned (OCI) architecture that improves scalability, reliability and deployment safety
Plan and carry out safe, incremental migrations across a very large production fleet
Partner with kernel, networking, hardware, and capacity teams to shape new platform capabilities
Mentor engineers through design reviews, code reviews, and technical coaching, and raise the team's engineering and operational standards
Write and present technical proposals that build alignment across teams and organizations

Minimum Qualifications

Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience
Deep knowledge of Linux internals relevant to containers, such as cgroups, namespaces, process management, and resource accounting
Experience leading technical direction for a team and delivering complex, multi-quarter infrastructure projects
Experience designing and running large-scale distributed or fleet-wide infrastructures in production
Experience communicating technical decisions in writing and in presentations to technical and non-technical stakeholders, and influencing direction across teams through proposals and stakeholder alignment

Preferred Qualifications

Experience running fleet-wide migrations or rollouts with strong safety and observability practices
Hands-on eBPF experience, especially for networking (TC, XDP, cgroup hooks) or observability
Background in Linux networking, such as virtual network devices, routing, and packet path performance tuning
Experience with container runtimes and ecosystems such as OCI, runc/crun, containerd, Kubernetes node components, or systemd
Experience with performance isolation in multi-tenant environments, such as CPU scheduling, memory pressure management, I/O control and PSI
Contributions to the Linux kernel or open-source container and networking projects
