Job description

About Mach Industries

Founded in 2022, 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 180 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.

The Role

Mach Industries is seeking Mechanical Design Engineers to join our revolutionary new division, Mach Propulsion. We’re developing a high-performance small turbine engine from the ground up, designed for scalable, high-rate manufacturing. This is a unique opportunity to apply your experience to a first-of-its-kind propulsion system. We’re looking for engineers with foundational experience in propulsion, drivetrain systems, or rotating machinery who are excited to solve complex engineering problems in a fast-paced, hands-on environment.

Key Responsibilities

• Design and Development: Design turbojet engine components and subsystems using Siemens NX, leveraging tools such as CAD, CFD, and FEA. Produce 3D models and 2D drawings optimized for manufacturing and performance.

• Full Lifecycle Ownership: Participate in concept generation, trade studies, prototyping, testing, and iteration. Engage directly with test teams to validate your hardware.

• Team Collaboration: Work closely with fabrication, machining, test, and engineering teams to ensure high-quality, on-time delivery of components.

Required Qualifications

• BS in Mechanical, Aerospace, Electrical Engineering or related field.

• 2+ years of mechanical engineering experience in propulsion, powertrain, or mechanical assemblies involving high-speed rotating hardware.

• Proficient in Siemens NX and familiar with PLM tools like Teamcenter.

• Working knowledge of ASME Y14.5 for tolerance control and manufacturability.

• Strong base in structures, materials, and manufacturing processes.

• Experience with prototyping and testing; comfortable in lab and shop environments.

• Must be a U.S. Person due to required access to U.S. export-controlled information or facilities.

Preferred Qualifications

• Experience designing or developing turbomachinery, small turbine engines, or air-breathing propulsion systems.

• Familiarity with high-rate manufacturing methods and strong understanding of DFM principles.

• Exposure to advanced materials such as composites and high-temperature alloys in propulsion environments.

• Experience supporting or leading test rig design, component integration, or validation of hardware.

• Understanding of defense or aerospace regulations and qualification processes.
