Top Linux Jobs

Mid-level software engineer supporting a defense program: develop and maintain software solutions using Zabbix, Python, Java, CSC, and Linux. Must hold active Top Secret/SCI with polygraph and contribute to mission-critical systems.

Develop and maintain Java-based mission-focused software on a small team. Implement services, CI/CD, containerized deployments, and backend integrations using Git, Gradle, Docker, REST, and Linux. Support ops and limited UI work as needed.

Develop, sustain, and troubleshoot a suite of mission-focused software applications. Implement, test, and integrate with COTS/GOTS/FOSS; build containerized services (Docker, Kubernetes, Helm); work with NoSQL/Databases, messaging, CI/CD, and IaC. Support evolving mission needs while holding required security clearance.

Design, implement, and optimize scalable data ingress/egress pipelines and distributed processing (Apache Spark). Develop orchestration using Apache Airflow, automate with Bash/Linux, code in Python/Java, perform data wrangling in Jupyter using pandas/NumPy, query large datasets with SQL, ensure data quality, and use Git for source control.

Design, develop, test, troubleshoot, and sustain a mission-focused enterprise web application in a containerized Linux/Kubernetes environment. Collaborate with product owners, system and project engineers to implement CI/CD, REST interfaces, and SQL-backed services while maintaining operational readiness for government missions.

The Linux Kernel Developer will innovate on the Linux operating system, focusing on high-performance file systems and collaborating with the upstream community.

Develop and maintain C++ machine control and data analysis software for advanced mask inspection systems. Collaborate with multidisciplinary teams to define system requirements, optimize performance, support integration and testing, and resolve customer escalations. Work in Linux environments and leverage RPC/REST APIs, containerization, and modern UI frameworks as needed.

Architect, develop, maintain, and enhance full-stack software systems across the SDLC. Deliver scalable, high-performance solutions for analytics, large data sets, and real-time systems. Collaborate with stakeholders, design modular reusable components, optimize performance, and mentor developers while supporting sustainment and customer-focused delivery.

Architect technical solutions for AIOS, lead proof-of-concept developments, define AIOS evolution roadmap, and ensure high-quality implementation with engineering teams.

Develop software to manage a fleet of Linux systems. Requires Linux internals, release/change-engineering development, C-like large-scale programming (C99), OpenSSL, Git/Gerrit, and use of Linux toolchain (gcc, make, rpm). Knowledge of systemd and sysv init required; AIX init is a plus.

Develop Linux system software in C with knowledge of the Linux boot process. Work on RPM-based distros (Red Hat/OEL), systemd and sysvinit, and OpenSSL; Golang and cross-platform experience are nice-to-haves.

Join Canonical as a graduate software engineer to write high-quality code across the open source stack, work on Linux system-level and application projects, engage with communities, respond to customer issues, and develop security-aware software while collaborating remotely and attending biannual in-person team sprints.
