Software Build, Tools & Infrastructure Engineer
About The Position
Quest Defense Systems and Solutions is seeking experienced Software Build, Tools & Infrastructure Engineers to join our team to supplement the customer team, maintain engine control tools, build systems, and simulation environments. This role focuses on sustaining critical build, CI, and debugging infrastructure for embedded/aerospace-related software projects. The ideal candidate has strong scripting skills and hands-on experience maintaining complex, multi-toolchain build pipelines in a mission-critical or regulated environment. Due to the nature of the project, all applicants must be U.S. citizens. This role can be done remotely, with a strong preference for candidates based in Cincinnati, OH.
Requirements
- Strong scripting/programming: Perl, Python, Tcl, PostScript (for legacy document/build processing).
- Hands-on knowledge of Apache Ant.
- Familiarity with IBM Engineering Lifecycle Management (ELM) tools, including: Engineering Workflow Management (EWM) for build definitions and pipelines.
- Engineering Test Management (ETM) (if integrated with build/validation).
- Experience managing build artifacts, repositories (Artifactory preferred), and CI failures.
- Deep understanding of embedded/aerospace software toolchain: SCADE (for model-based design).
- Simics (full-system simulation and debugging, including breakpoint setup, tracing, reverse execution).
- NPSS (Numerical Propulsion System Simulation, for propulsion/thermodynamic modeling if applicable).
- ARM compiler toolchain.
- Makefiles, C programming, and embedded build processes.
- Experience with embedded debuggers and low-level debugging in simulated environments (Simics preferred).
- Ability to write Python/C-based extensions or helpers for simulation tools.
- Broad knowledge of software architecture in embedded systems (real-time constraints, hardware-software interaction).
- Comfortable working with legacy codebases and tools.
- Strong problem-solving skills for root-cause analysis in production-like CI/build environments.
- Excellent documentation skills to create maintainable procedures and guides.
Nice To Haves
- Prior experience in aerospace, defense, or propulsion system software development.
- Familiarity with migration of legacy build systems or artifact repositories.
- Knowledge of continuous integration best practices in regulated industries.
- Onsite in Cincinnati, OH a plus
- Experience in the adoption and/or integration of emerging technologies (e.g., generative AI, automation platforms, digital assistants) into day-to-day operations for continuous improvement.
Responsibilities
- Maintain the software build ecosystem, ensuring stability, reliability, and ongoing support for development and release activities.
- Perform daily monitoring and maintenance: restart services following machine reboots or network disruptions.
- Monitor build/CI jobs for failures, diagnose root causes (build machine issues, configuration errors, etc.), take corrective actions, or implement fixes.
- Maintain and troubleshoot CI pipelines and related infrastructure.
- Handle user account provisioning and access management.
- Support migration activities and IT-related administrative tasks for repositories and artifacts.
- Debug and fix issues in build tools, makefiles, and build scripts.
- Implement makefile modifications and build process improvements
- Debug issues in engine system simulated test environment.
- Develop and add helper functions/scripts to improve simulation usability and diagnostics.
- Create standardized work instructions/procedures (e.g., troubleshooting guides or standard operating procedures) for developers to follow when encountering software/simulation issues.
Benefits
- Competitive pay, comprehensive medical/dental/life and disability coverage, 401(k) with employer match, professional development support, and a flexible, friendly workplace.
