Job description

Description

You will build and operate the pipelines, environments, and release machinery that let engineers move quickly across both unclassified and classified development enclaves, including the air-gapped ones, where every release depends on the reproducibility of the build and tool chains.

What you will do

Build and CI/CD

• Own CI/CD pipelines across embedded, firmware, and application build targets
• Manage compilation toolchains, build reproducibility, and dependency caching
• Automate test execution, including hardware-in-the-loop test integration where applicable
• Reduce build and feedback times as a standing objective

Development environments

• Provision and maintain development, integration, and test environments across security domains
• Operate artifact repositories, container registries, and internal package mirrors
• Manage the transfer and synchronization processes that keep air-gapped enclaves current

Release engineering and configuration management

• Own baseline definition, versioning, and release packaging for delivered software and firmware
• Maintain configuration management records supporting program baseline control
• Build and validate installation, update, and rollback procedures for fielded systems

Infrastructure

• Manage infrastructure-as-code for development and test infrastructure
• Administer source control, issue tracking, and engineering tooling
• Support capacity planning and infrastructure lifecycle

Requirements

Minimum qualifications

• BS in Computer Science or equivalent hands-on experience
• 4+ years in DevOps, build engineering, or platform engineering
• Hands-on experience with Bitbucket, GitLab CI, or equivalent
• Experience with containerization and infrastructure-as-code
• Strong scripting ability in Python and Bash
• Linux system administration depth
• Active TS/SCI

Preferred qualifications

• Prior experience operating build infrastructure in air-gapped or classified enclaves
• Embedded and cross-compiled build experience (Yocto, Buildroot, vendor SDKs)
• Hardware-in-the-loop or automated test lab infrastructure experience
• Familiarity with configuration management expectations on programs of record
• Ability to obtain a TS/SCI clearance
