New Graduate Engineer, Electrical​/Avionics Huntington , California,

Huntington Beach, California, United States

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 New Graduate Electrical & Avionics Engineer to support the design, development, integration, and testing of electrical systems for next-generation autonomous defense platforms. In this role, you will work across circuit-board design, avionics, power distribution, communications, vehicle harnessing, and hardware testing to take systems from early prototypes through flight-ready production hardware.

You will collaborate closely with mechanical, software, systems, manufacturing, and test engineers to rapidly build, troubleshoot, and validate reliable electrical systems. This role is ideal for a hands‑on engineer who wants broad technical ownership, learns quickly, and is excited to build critical hardware in a fast‑paced environment.

• Design and develop electrical and avionics systems for autonomous aircraft, missiles, propulsion systems, and related defense platforms.
• Support schematic capture, component selection, PCB layout, stack‑up design, and board bring‑up.
• Design circuits incorporating microcontrollers, high- and low-speed communication buses, analog and digital interfaces, sensors, power distribution, EMI protection, and ESD protection.
• Develop flight avionics, guidance and control electronics, communications systems, power electronics, and supporting test hardware.
• Design and integrate vehicle wiring harnesses, connectors, sensors, actuators, and electrical interfaces.
• Build prototypes and conduct bench‑level, subsystem, and vehicle‑level testing using oscilloscopes, logic analyzers, power supplies, electronic loads, and other laboratory equipment.
• Troubleshoot electrical hardware, identify root causes, and implement design or process improvements.
• Support hardware‑in‑the‑loop testing, environmental testing, system integration, and flight or field‑test activities.
• Develop and maintain schematics, drawings, bills of materials, test procedures, design documentation, and product specifications.
• Partner with mechanical, software, systems, manufacturing, and test teams to ensure electrical components integrate successfully into the overall vehicle.
• Work alongside manufacturing and quality teams to transition designs from prototype builds into reliable, repeatable production.
• Ensure designs meet applicable performance, reliability, safety, quality, and regulatory requirements.

• Bachelor’s, master’s, or doctoral degree in Electrical Engineering, Computer Engineering, Aerospace Engineering, or a related technical field.
• Graduating by summer 2027
• Electrical or avionics experience gained through internships, research, academic projects, student competition teams, or professional roles.
• Foundational understanding of analog and digital electronics, circuit design, power systems, and electrical interfaces.
• Experience with schematic capture or PCB design software such as Altium Designer, Cadence, KiCad, or an equivalent tool.
