Mechanical Engineer

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.
Role Description:

• Design and develop mechanical systems for underwater vehicles, contributing to structural layouts, pressure housings, propulsion integration, and subsystem packaging.
• Work across the full development cycle from concept and analysis through fabrication, integration, and testing, applying a strong first-principles engineering mindset to solve complex design problems.
• Collaborate closely with electrical, software, and systems engineers to integrate propulsion, sensing, power, and payload subsystems into robust electromechanical systems.
• Design and fabricate custom hardware, fixtures, and test infrastructure to enable component validation, system integration, and field evaluation.
• Support hands-on build, assembly, and debugging of prototypes, driving rapid iteration and continuous improvement in system performance, reliability, and manufacturability.

Required Qualifications:

• B.S. or M.S. in Mechanical Engineering or related technical field.
• 1–7 years of experience designing and building mechanical or electromechanical systems.
• Proficiency with CAD tools (SolidWorks preferred) and experience producing clear engineering documentation, including drawings and tolerance specifications.
• Experience with structural design, material selection, sealing strategies, and environmental considerations such as pressure, vibration, and corrosion.
• Hands-on experience with prototyping, fabrication, assembly, and mechanical troubleshooting.
• Experience working in multidisciplinary engineering environments with electrical and software teams.
• Strong first-principles engineering mindset and practical design approach.
• U.S. work authorization and ability to obtain a security clearance.
