Quest Defense Systems and Solutions is seeking experienced Software Build, Tools & Infrastructure Engineers to join our team in supplement the customer team maintaining engine controls 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 US Citizens. This role is remote with a strong preference to be in Cincinnati, OH.

Requirements

Strong scripting/programming: Perl, Python, Tcl, PostScript (for legacy document/build processing).
Build and CI expertise: 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.
Debugging capabilities: 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).
