Mechanical Engineering Intern

Albacore Inc. is a Philadelphia-based company building highly-capable, mass-producible drone submarines to defend sovereign waters of America and allied nations. We are backed with more than $10 million from Y Combinator and venture capital investors. Our team is hiring mechanical engineering interns to join our team for the summer. During that timeframe, you will help us: Scale vehicle production to double-digits. Conduct international demonstrations to NATO. Blow up a ship (legally). Role description: Contribute to mechanical design, integration, and validation efforts, supporting structural layouts, packaging, sealing strategies, and subsystem integration (propulsion, sensing, power). Design and fabricate custom hardware to enable component verification, system integration, and performance evaluation, applying a strong first-principles engineering approach. Execute focused technical investigations to assess new concepts, mechanisms, and materials that improve performance, reliability, and durability. Desired qualifications: Experience designing and building mechanical or electromechanical systems. Proficient in CAD tools (SolidWorks preferred) with working knowledge of GD&T, tolerance stack-ups, and design for manufacturability; capable of producing clear, production-ready documentation. Skilled in structural analysis, material selection, and environmental design considerations including pressure, vibration, and corrosion for marine applications. Comfortable with hands-on prototyping, fabrication, assembly, troubleshooting, and iterative testing in laboratory and field environments. U.S. work authorization and ability to obtain a security clearance.
