About the job
Requirements
Currently pursuing a Bachelor of Science, Master of Science, or PhD in Mechanical Engineering, Marine Engineering, Naval Architecture, Electrical Engineering, Mechatronics, or a related field.
Have a strong foundation in mechanical engineering, including computer-aided design, simulation, and materials selection.
Have hands-on prototyping and fabrication experience through clubs, projects, internships, competition teams, research, or equivalent work.
Be comfortable working close to hardware, tools, and physical systems.
Be comfortable working around industrial equipment and shipboard machinery.
Provide a portfolio or other evidence of hands-on building when applying.
Responsibilities
Contribute to the integration of onboard mechanical and electrical systems deployed on operational vessels.
Support the design of sensor mounts, equipment enclosures, electrical panels, and cable routing layouts.
Assist with hardware installation, assembly, and system bring-up.
Participate in vessel integration, commissioning, and testing activities.
Support development and execution of structured test campaigns for deployed systems.
Help identify and troubleshoot mechanical or electrical integration issues in real-world environments.
Work closely with software, electrical, and mechanical engineers to improve system reliability and deployment efficiency.
Contribute to documentation, including integration procedures, drawings, and system layouts.
Desired Qualifications
Experience with robotics, marine systems, automotive, aerospace, or industrial hardware projects.
Familiarity with electrical systems, harnessing, or cable routing.
Experience building or integrating electromechanical systems.
Interest in maritime systems, offshore operations, robotics, or heavy industry.
About Oceanus
Oceanus Marine Technologies is building the operating platform for the modern maritime world.
Global trade runs on ships, and we’re redefining what’s possible at sea by leveraging modern technology.
We’re a small, hands-on team based in El Segundo building full-stack systems that perform in real operating conditions across vessels, ports, and fleets. We focus on practical, deployable technology that brings safety oversight, automation, and coordination to complex maritime environments.
Our founding team previously built and operated SpaceX’s Autonomous Spaceport Droneships, which are among the most advanced autonomous maritime systems ever deployed. Today, we work with leading U.S. operators to bring that same rigor and systems thinking to the next generation of maritime infrastructure.
About the Role
We’re hiring a Naval Architect Intern, for the Summer or Fall term. Summer internships begin in June, and Fall internships begin in September, with a minimum 12 week commitment, and a preferred commitment of 4 to 8 months.
As a Naval Architect Intern, you’ll work on initiatives that improve how onboard systems are integrated, deployed, and operated across commercial vessels. You’ll help solve complex, real-world engineering problems spanning mechanical integration, electrical systems, packaging, test, and deployment in demanding marine environments.
This role sits at the intersection of mechanical, electrical, and marine engineering. You’ll contribute to the integration of sensors, compute, power systems, cabling, enclosures, and onboard infrastructure that must operate reliably in harsh real-world conditions.
Our size allows interns to take significant ownership. We give interns autonomy on interdisciplinary projects that move quickly from idea to implementation. Our philosophy is to build and test in days or weeks, not months.
Because of this, a portfolio or evidence of hands-on building is required to apply. Show us projects, systems, competition work, research, or fabrication experience that reflect strong engineering fundamentals, execution, and curiosity.
