Develops unmanned military systems and propulsion
Founded in 2023, Mach Industries is a rapidly growing defense technology company focused on developing next-generation autonomous defense platforms. 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.
Our 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.
Mach Industries is seeking a Propulsion Systems & Mechanical Integration Engineer to own the mechanical integration of propulsion systems across our next-generation defense platforms. In this hands-on role, you will work at the intersection of propulsion, structures, fluids, thermal management, avionics, and vehicle systems to turn propulsion concepts into reliable, testable, manufacturable hardware.
You will integrate next-generation engines, fuel systems, valves, pumps, tanks, actuators, thermal protection, and associated support hardware in tightly constrained aerospace vehicles. You will drive the mechanical architecture and interfaces required to accomodate propulsion systems while balancing performance, mass, packaging, manufacturability, reliability, and cost.
At Mach Industries, we are redefining the future of defense through advanced, scalable platforms. As a Mechanical Engineer, you will play a key role in prototyping and refining mechanical systems, and optimizing designs for performance and scalability. Collaborating with a multidisciplinary team, you’ll help shape the next wave of defense technologies, from concept to deployment.
Own mechanical integration of propulsion systems from early architecture and concept development through prototype, test, qualification, and production.
Develop and maintain propulsion mechanical interfaces, including engines, tanks, pumps, valves, regulators, plumbing, actuators, mounts, supports, and vehicle structure.
Define propulsion system packaging and installation architectures, balancing performance, mass, center of gravity, volume, thermal environment, accessibility, and manufacturability.
Translate engine and vehicle level requirements into feed system requirements, interface documentation, and hardware
Perform first-order sizing and engineering analysis of mounts, brackets, plumbing supports, tanks, interfaces, and other propulsion hardware.
Develop and manage propulsion mechanical interface requirements, ICDs, interface drawings, layouts, and configuration-controlled design data.
Design and release mechanical hardware including flight hardware, prototype, test fixtures, and ground support equipment using 3D CAD, drawings, GD&T, and appropriate engineering standards.
Analyze and resolve propulsion-induced loads, vibration, thermal expansion, pressure loads, shock, and other dynamic environments at mechanical interfaces.
Design and support installation, removal, servicing, inspection, and test of propulsion systems.
Support propulsion and vehicle-level testing, including test planning, hardware readiness, instrumentation, anomaly resolution, and post-test assessment.
Author technical documentation, test plans, interface documentation, trade studies, and engineering milestones for cross-functional and leadership review.
Ability to support critical development and test milestones, including occasional extended hours and weekends as needed
5+ years of experience in mechanical, aerospace, or propulsion engineering, with significant experience developing and integrating complex mechanical systems in a fast-paced environment.
Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Electrical Engineering, or a related field.
Strong skills in 3D modeling and CAD tools (e.g., NX, SolidWorks, etc.) for mechanical design and iteration including GD&T per ASME Y14.5
Strong understanding of propulsion mechanical systems, including some combination of engines, fuel systems, tanks, pumps, valves, regulators, plumbing, mounts, and associated support hardware.
Advanced degree (Masters of PhD) in Mechanical Engineering, Aerospace Engineering, Propulsion, or a related field.
Experience with structural analysis, FEA, Thermal Desktop, or other analytical tools used to evaluate propulsion interfaces and hardware.
Experience with programming languages (e.g. python, MATLAB, C++) for analytical modeling, simulation and engineering problem-solving.
Direct experience designing or integrating engine mounts, fuel tanks, pressure vessels, fluid lines, valves, pumps, regulators, manifolds, and related hardware.
Familiarity with slosh dynamics and mitigation systems including baffles, foam, bladders, etc.
