Senior Platform Software Engineer

Responsibilities

• As a Principal Platform Software Engineer on the Container Instances Data Plane team, you will:
• - Design, build, and maintain production-grade Linux hypervisor and guest operating-system images used to run containerized workloads. - Develop automated processes for creating, customizing, validating, publishing, and safely rolling out Linux images, including formats such as qcow2. - Customize Linux at the kernel-facing, systemd, networking, storage, security, package-management, and boot layers to meet platform requirements. - Build and maintain RPM packages, repositories, image-composition workflows, and release manifests using DNF/YUM and, where applicable, OSTree-based technologies. - Develop and maintain lifecycle-management and platform components in Java, Go, and shell scripting. - Integrate and troubleshoot container runtimes and OCI container behavior, including containerd/runc or related technologies. - Design and optimize virtualization using QEMU/KVM and paravirtualized networking, storage, and host/guest communication devices. - Improve performance, boot time, reliability, resource utilization, isolation, and scalability across virtualized Linux environments. - Troubleshoot complex issues across the Linux kernel, virtualization stack, container runtimes, networking, storage, security, and distributed cloud infrastructure. - Design and execute functional, integration, performance, regression, failure, and security testing. - Build CI/CD and image-release pipelines that automate package integration, vulnerability remediation, security validation, qualification, canary deployment, compatibility checks, monitoring, rollback, and release evidence. - Integrate the data plane with OCI services and APIs for networking, storage, identity, telemetry, and infrastructure lifecycle management. - Automate infrastructure provisioning and validation using Terraform and other approved Infrastructure as Code practices. - Coordinate safe releases across large hypervisor fleets and multiple global regions, including staged deployment and operational readiness. - Participate in on-call and incident response, drive root-cause analysis, and improve monitoring, runbooks, and service reliability. - Produce clear design documents, operational procedures, troubleshooting guides, and architectural decisions; explain technical tradeoffs and influence engineering partners across teams. - Mentor engineers and provide technical leadership through design quality, reviews, debugging, and end-to-end ownership rather than through people-management responsibility.
