Our mechanical engineering team designs and builds these systems, providing customers with products they can count on. Our team has grown to keep pace with rapidly multiplying projects, and now we’re looking to recruit a junior engineer. This person will work closely with senior engineers and vehicle design leadership, taking on real design and fabrication work while building the skills and judgment to take on greater ownership over time.\nRole Details:\nEveryone on this team gets real ownership over their work, along with support and mentorship from senior engineers. Some tasks will include:\nDesigning parts and assemblies, with guidance from senior engineers\nSupporting timeline and plan creation\nReviewing, detailing, and configuration management of CAD models\nDesigning (CAD) fixtures, tooling, jigs\nSourcing and communicating with suppliers\nFilling out vehicle BOM and evaluating production/procurement options\nSupporting process refinements to increase production efficiency\nAssembly and Q&A of incoming parts from external suppliers\nTesting new and existing designs of components of the vessels\nAbout You:\nYou’re a self-starter with a get-stuff-done attitude, a solid foundation in mechanical engineering and fabrication, and an interest in the maritime space. Specifically, you have:\n0-2 years of experience (internships, co-ops, school projects, or professional experience) working on mechanical parts in a team environment\nWorking knowledge of Solidworks\nA foundational understanding of mechanical engineering, structures, assembly and DFM trade-offs, and fabrication methods\nInterest in or background in the maritime space, from work, school projects, competitions, or personal time on and around the water\nSome exposure to how different manufacturing processes (i.e. CNC milling, 3D printing, waterjet, etc.) affect design\nWillingness to learn to work with outsourced parts and external vendors/fabricators\nStrong communication skills with vendors and internal team\nGood organizational skills - tracking BOMs, following up with suppliers, etc.\nAttention to detail, with a basic understanding of GD&T and an interest in learning to create drawings for suppliers\nExperience in startups, competitions (e.g. FSAE, Baja SAE, robotics teams), or similarly tight-timeline settings\nBasic understanding of electrical and software needs for electro-mechanical systems is a plus\nDue to export control requirements applicable to this position, we are only able to consider U.S. persons, as defined by U.S. export control laws. This includes U.S. citizens, lawful permanent residents, and individuals granted asylee or refugee status\nBonus:\nAn understanding of basic naval architecture\nBasic understanding of composites\nUnderstanding of autonomous systems\nExperience with combustion engines and hybrid power systems\nAbout Seasats:\nAt Seasats, we're passionate about delivering maritime robotics solutions to redefine the maritime industry. Our primary products are unmanned surface vehicles (USVs), designed to carry sensors at sea for months at a time. Our USVs 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.\nAlong with your salary, you’ll receive perks including:\nCompetitive insurance (including a 99% employer-covered Gold HMO plan or other options)\n401k matching up to 4% of salary\nFour free lunches per week\nAn employee activity fund\nA pet-friendly office\nUnlimited/Flex PTO\nHiring Notes:\nWhen you apply, you’ll be asked to provide a resume and answer a few screening questions.\nPlease note that we are currently unable to sponsor employment visas, so candidates must be independently authorized to work in the United States.\nWe appreciate diverse perspectives and life experiences, and we’re committed to building a team that reflects a wide range of backgrounds.
