At the core of our mission is the commitment to delivering scalable, decentralized defense systems that enhance the strategic capabilities of the United States and its allies. With a workforce of approximately 350 employees, we operate with startup agility and ambition.\nOur vision is to redefine the future of warfare through cutting-edge manufacturing, innovation at speed, and unwavering focus on national security. We are dedicated to solving the next generation of warfare with lethal systems that deter kinetic conflict and protect global security.\nThe Role\nMach Industries is building autonomous systems that must be thoroughly tested and validated in a multi layered process, long before they are flown. As a Senior Software Engineer, Infrastructure & Simulation, you will build the simulation and validation infrastructure that enables rapid iteration and high confidence in real-world performance. Your work will sit at the foundation of our autonomy stack, powering Monte Carlo, software-in-the-loop (SITL), hardware-in-the-loop (HITL) and large-scale simulations across Mach product lines.\nKey Responsibilities\nDesign, build, and maintain simulation and validation infrastructure for aircraft systems, including discrete simulations of avionics, sensors, power distribution, flight controls, and embedded software.\n\nDevelop and operate Software-in-the-Loop (SITL) and Hardware-in-the-Loop (HITL) frameworks to support rapid development, regression testing, and system validation across flight autonomy and embedded stacks.\n\nBuild software infrastructure to emulate bare-metal drivers, avionics peripherals, and aircraft system behaviors, enabling early validation, fault injection, and failure-mode testing.\n\nCreate and scale automated test pipelines that integrate simulation and HIL into CI/CD workflows to continuously validate flight software performance, safety, and reliability.\n\nCollaborate closely with autonomy, embedded, avionics, and systems engineers to define robust test strategies aligned with real-world flight profiles, environmental conditions, and operational constraints.\n\nImprove simulation fidelity, determinism, and performance to close the gap between simulated behavior and real aircraft dynamics.\n\nOptimize build and test infrastructure to leverage parallel execution, cluster computing, and shared compute resources for large-scale simulation and regression workloads.\n\nDefine, track, and evolve metrics for test quality, coverage, and traceability, driving continuous improvement in aircraft software validation and confidence.\n\nRequired Qualifications \nStrong software engineering fundamentals with 5+ years of experience building production systems or developer infrastructure.\n\nProficiency in C++ and at least one systems language such as Python, Rust, or C.\n\nExperience building or working with simulation, testing, or validation frameworks for complex software or embedded systems.\n\nFamiliarity with CI/CD pipelines, containerization (Docker), and modern build systems.\n\nExperience scaling test infrastructure across distributed or cloud compute environments.\n\nKnowledge of infrastructure tooling such as Jenkins, GitHub Actions, Terraform, or similar.\n\nPreferred Qualifications \nExperience with SITL / HITL environments for robotics, autonomy, or embedded platforms.\n\nFamiliarity with Linux-based systems, embedded software, or low-level drivers.\n\nBackground in safety-critical or high-reliability systems.\n\nAdditional Requirements\nAvailable to work extended hours and weekends as needed\nITAR Requirements\nTo conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
