Role Overview

Seasats builds unmanned surface vessels that carry sensors at sea for months at a time. Our platforms serve defense, scientific, and commercial customers who need to see, monitor, and respond across vast stretches of open water.

Role Details

You will:

• Install pre-built cable assemblies into connector plates per wiring diagrams and technical drawings for Lightfish, Quickfish, and Heavyfish
• Verify correct cable-to-connector mapping and pin-out against schematics before installing
• Install completed connector plates into the vessel hull
• Route, secure, and manage cable runs inside vessel hulls including strain relief, chafe protection, and clean routing for serviceability
• Label cables and connectors according to specification and maintain accurate traceability
• Wire and terminate solar panel connections as part of the standard build
• Diagnose and replace damaged or worn cables during rework, repair, or field return
• Apply sealing and waterproofing around connector plate installs for marine-rated protection
• Work alongside mechanical and electrical assembly technicians during install
• Perform quality control inspections on connector plate assemblies and cable installs against company standards
• Document install records, test results, and discrepancies; flag and help fix recurring issues

About You

• Hands-on experience installing cables, connectors, or wire assemblies into finished products
• Experience with cable routing and management (electrical panel wiring, wire harness work, or similar) in a professional or hobbyist setting
• Ability to read wiring diagrams and technical drawings
• Experience mating and installing connectors across multiple connector types
• Comfort working with gaskets, or other sealing methods for environmental protection
• Exceptional organizational skills and attention-to-detail: inconsistent labeling, a messy cable run, or a disorganized bench should genuinely bother you, and you fix it on sight without being asked
• The ability to perform precise, repetitive assembly work while maintaining consistent quality
• Good communication skills and the judgment to stop and ask questions when something does not match the documentation
• Comfort working independently and alongside technicians and engineers in a fast-moving production environment

Bonus points if you have

• Soldering and crimping experience - you'll occasionally take on solar panel wiring and cable repair/replacement alongside your core install work
• Background in marine, aerospace, or defense manufacturing
• Experience supporting multiple concurrent product lines in a fast-scaling production environment

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)
