DevOps Build & Release Engineer (Hybrid Eligible)

We are hiring a DevOps Build & Release Engineer. This position resides in the DevOps Engineering Team within the Research IT Infrastructure group of the Research Computing Support Division of the Information Technology Services Directorate (ITSD) at Oak Ridge National Laboratory (ORNL). This position will require a regular on-site presence. We optimize our workflows and monitoring solutions to take advantage of our 24/7 operations staff, which significantly reduces the need for off-hours support.

DevOps Engineering facilitates the delivery, operation, and monitoring of developed applications for R&D projects.

We operate within an Agile Scrum workflow and work with scientific researchers to provide automation solutions. Our success is measured by the additional capabilities, cost savings, and optimizations we provide to our research partners. To achieve this, we are growing our team and offering new capabilities. Our goal is to allow researchers to focus on their projects rather than IT concerns.

Major Duties/Responsibilities:

• Directly collaborate with research teams to develop a suite of applications.
• Provide support for continuous integration and delivery, configuration management, and release management throughout the SDLC.
• Coordinate with the team to identify, track and address priorities, discrepancies, dependencies, and risks associated with releases, while ensuring alignment with proper processes.
• Collaborate with the HPC engineering team to optimize solutions for performance and scalability in HPC environments. Collaboration with colleagues across the organization is imperative to ensure the delivery of secure solutions in compliance with Internal Operating Procedures.
• Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote equal opportunity by fostering a respectful workplace – in how we treat one another, work together, and measure success.

Our Stack and Workflow:

• Work planning and documentation – Gitlab, Jira/Confluence.
• Code repository, CI/CD – Gitlab.
• Configuration and Package Management – Spack, Pip.
• Monitoring, Analytics and Visualization - Prometheus, Grafana, Elasticsearch, Checkmarx.
• Other leveraged technologies include, but are not limited to Slurm, MPI, CUDA, and Harbor depending on program needs.

Basic Qualifications:

• BS degree in computer science, computer engineering, information systems or a related field, and 5 years of relevant professional experience (or an equivalent combination of education and experience will be considered).
• 3+ years of experience leading or coordinating Software Development Lifecycle (SDLC) processes.
• Hands-on experience with Linux-based software development, including software builds, CI workflows, and troubleshooting in multi-user environments.
• Experience using Git and building CI/CD pipelines with tools such as GitLab CI, Jenkins, or similar.
• Proficiency with Bash/shell scripting and Python for automation.
• Experience with compiler toolchains (GCC, Clang, Intel) and build systems such as CMake or Make.
• Ability to diagnose and resolve software build and runtime issues, including dependency, ABI, linker/loader, permissions, and environment conflicts.
• Experience building and deploying software with package/build managers such as Spack or similar tools.
• Experience developing and maintaining technical documentation, including build guides, release notes, and operational runbooks.

Preferred Qualifications:

• Active DOE Q Clearance.
• Familiarity with C/C++ sufficient to debug build issues and make minor fixes.
• Experience supporting software builds and CI workflows in an HPC environment (e.g., Slurm job submission and debugging).
• Experience creating and maintaining environment modulefiles (Lmod/Environment Modules), managing defaults, and minimizing version conflicts.
• Experience with HPC-appropriate container workflow (Apptainer/Singularity preferred).
