Job description

Role: Mechanical Engineering Intern

Type: Internship (full-time, 40 hours/week)

Location: San Diego, CA (in-office)

Pay: $30/hourly

Role Overview

Seasats designs and deploys autonomous surface vehicles that operate at sea for months at a time. These missions depend on robust, well-designed mechanical systems that can survive harsh maritime environments with minimal human intervention.

As a Mechanical Engineering Intern, you'll work closely with our mechanical engineering team to support the design, fabrication, assembly, and testing of vehicle hardware, contributing to projects that actually go to sea.

This is a full-time, in-person internship running from approximately August 18 through December 31, 2026. Applicants should be available to work throughout the duration of the internship.

Role Details

• Design mechanical parts and simple assemblies in CAD (SolidWorks)
• Update and maintain CAD models, drawings, and basic BOMs
• Assist with fixtures, tooling, and jigs for assembly and testing
• Support part sourcing and communication with suppliers
• Help assemble and inspect mechanical components and subassemblies
• Participate in testing of new and existing vehicle components
• Support documentation, configuration management, and organization of design files
• Collaborate with mechanical, electrical, and software engineers on electro-mechanical systems

About You

You're someone who wants to design and build things; you've probably already built some cool stuff. You proactively spot problems, ask questions, and pursue solutions. Specifically, you probably have:

• Completed 2–3 years of coursework towards a BS or MS in Mechanical Engineering or a related field
• Hands-on experience using SolidWorks for part and assembly design
• Ability to read and create basic mechanical drawings
• Strong attention to detail and willingness to iterate based on feedback
• Comfortable working in a fast-moving, hands-on environment

Additionally, you may have one or more of the following qualifications:

• Internship, project, club, or competition experience (Formula SAE, robotics, robotics teams, etc.)
• Experience with manufacturing methods (3D printing, CNC, waterjet, shop tools)
• Interest in robotics, autonomous systems, or maritime environments
• Basic familiarity with GD&T
• Exposure to electrical or software systems in a mechanical context

About Seasats

At Seasats, we're passionate about delivering maritime robotics solutions to redefine the maritime industry. Our primary products are autonomous surface vehicles (ASVs), designed to carry sensors at sea for months at a time. Our ASVs provide persistent monitoring and data acquisition to defense, scientific, and commercial customers, and have autonomously crossed both the Pacific and Atlantic oceans. After thousands of years in which the only way to gather information from the ocean was to put people on a boat, these uncrewed vessels are transforming how humanity monitors and interacts with the ocean. Here, you'll find the space and opportunity to do your life’s best work.

Along With Your Salary, You’ll Receive Perks Including

• Competitive insurance (including a 99% employer-covered Gold HMO plan or other options)
• 401k matching up to 4% of salary
• Four free lunches per week
• An employee activity fund
• A pet-friendly office
• Unlimited/Flex PTO
