Top Senior Linux Jobs in Philadelphia, PA

Design, implement, and maintain embedded firmware and cloud-ready microservices/APIs. Develop embedded Linux using Yocto, integrate hardware and device drivers, improve CI/CD pipelines, mentor junior engineers, troubleshoot performance issues, and collaborate with cross-functional teams to deliver scalable, secure software for connected devices.

Develop and maintain Linux kernel components and live-patching infrastructure for Rocky Linux. Responsibilities include kernel design, C programming, debugging memory management and process scheduling issues, device-driver and hardware integration, performance optimization, code review, documentation, and mentoring junior developers. The role requires deep Linux kernel internals expertise, familiarity with x86 and ARM architectures, Git workflows, and at least five years of kernel development experience.

Design, build, monitor, and maintain large-scale Linux infrastructure supporting distributed S3-compatible object storage across multi-cloud environments. Responsibilities include kernel and storage optimization, network and hardware troubleshooting, automation with Chef or Ansible, observability, forecasting capacity, technical leadership, project coordination, mentoring, documentation, and on-call support.

Designs and maintains secure Linux OS components for hardened container images and cloud-native workloads. Responsibilities include remediating CVEs, patching and rebuilding packages across Linux distributions, hardening container images, managing SBOMs and software provenance, and automating reproducible OS build and CI/CD pipelines. The role requires deep Linux systems, package management, dependency, container runtime, and supply chain security expertise, along with cross-functional collaboration to deliver stable, secure OS baselines.

Analyze Linux system performance, design and implement performance enhancements, productize new servers and hardware, extend performance metrics and visualizations, and build diagnostic tooling. The role requires advanced C programming, Linux kernel expertise, virtualization knowledge, hardware enablement and debugging experience, performance analysis skills, and understanding of computer architecture, concurrency, algorithms, and hardware interconnects.

Designs, implements, administers, and supports critical Linux infrastructure and enterprise systems. Diagnoses system issues, develops remediation plans, supports application infrastructure, and contributes to compliance activities. Builds automation, deployment pipelines, and infrastructure-as-code solutions using Linux, cloud, Kubernetes, GitOps, and configuration-management tools. Partners with engineering, security, and operations teams to improve reliability, scalability, security, and deployment efficiency while mentoring junior engineers.

Designs and maintains system architectures across applications, infrastructure, and platforms. Provides technical leadership, translates requirements into scalable and secure solutions, optimizes reliability and performance, supports system integration, and collaborates with development, DevOps, security, and business stakeholders. Maintains technical documentation and participates in Agile delivery and continuous improvement. Preferred experience includes federal contracts, migrations, Ansible, Linux, Red Hat, cloud platforms, DevOps, CI/CD, and secure system design.

Design, build, and maintain embedded Linux environments and kernels across hardware platforms. Tasks include kernel patching, cross-compilation, networking, system diagnostics, automation, and collaboration with hardware, software, and QA teams to integrate applications with embedded OS platforms.

Lead design and implementation of gameplay and engine systems on Linux platforms. Mentor engineers, define technical specs, manage Linux infrastructure, optimize performance and security, integrate art, maintain documentation, support live services and mobile (iOS/Android) ports, and coordinate cross-team standards and tooling.

Own and architect Linux kernel-space enforcement for an identity security platform using eBPF and BPF LSM hooks. Build kernel and userspace enforcement boundary, optimize syscall hot paths, extend enforcement to containers and Kubernetes, ensure portability across kernel versions, collaborate on shared policy/backend, mentor engineers, and drive production-grade, low-latency security enforcement.

Optimize Ubuntu integration across latest IoT and server-class hardware, lead customer engagements, and work with open source communities in a remote, collaborative environment.
