Salary range: $71,000 - $90,000 / yr + stock options, 401k matching, and other benefits
Role Overview:
Seasats deploys unmanned surface vessels on multi-month missions that rely on top-quality mechanical systems. 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.
Role Details:
Everyone on this team gets real ownership over their work, along with support and mentorship from senior engineers. Some tasks will include:
Designing parts and assemblies, with guidance from senior engineers
Supporting timeline and plan creation
Reviewing, detailing, and configuration management of CAD models
Designing (CAD) fixtures, tooling, jigs
Sourcing and communicating with suppliers
Filling out vehicle BOM and evaluating production/procurement options
Supporting process refinements to increase production efficiency
Assembly and Q&A of incoming parts from external suppliers
Testing new and existing designs of components of the vessels
About You:
You’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:
0-2 years of experience (internships, co-ops, school projects, or professional experience) working on mechanical parts in a team environment
Working knowledge of Solidworks
A foundational understanding of mechanical engineering, structures, assembly and DFM trade-offs, and fabrication methods
Interest in or background in the maritime space, from work, school projects, competitions, or personal time on and around the water
Some exposure to how different manufacturing processes (i.e. CNC milling, 3D printing, waterjet, etc.) affect design
Willingness to learn to work with outsourced parts and external vendors/fabricators
Strong communication skills with vendors and internal team
Good organizational skills - tracking BOMs, following up with suppliers, etc.
Attention to detail, with a basic understanding of GD&T and an interest in learning to create drawings for suppliers
Experience in startups, competitions (e.g. FSAE, Baja SAE, robotics teams), or similarly tight-timeline settings
Basic understanding of electrical and software needs for electro-mechanical systems is a plus
