Software Engineer, Container Infrastructure (Technical Leadership)

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

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 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
