Mechanical Engineer - Build

Shinkei•El Segundo, CA

6d•Onsite

About The Position

This is a highly hands-on engineering role focused on building hardware that will be deployed into harsh maritime environments. You will be the primary owner of Poseidon system build reliability and drive the pace the company needs. You'll move between CAD reviews, wrench-in-hand assembly, troubleshooting on the floor, and pushing design updates. Success requires ownership, urgency, and a willingness to solve problems where they happen, not from behind a desk.

Requirements

1+ years of hands-on experience assembling or building electro-mechanical hardware; 3+ years preferred
Ability to read and produce CAD models, mechanical drawings, and specifications
Strong mechanical intuition with the ability to diagnose issues and propose fixes quickly
High proficiency with power tools, hand tools, and standard shop equipment
Comfortable owning tasks independently and driving work to completion
Strong communication skills and the ability to work closely with design engineers and technicians
Experience with build documentation or writing clear assembly instructions
Willingness to travel occasionally to fishing sites and work with the field engineering team on a dock or boat

Nice To Haves

Fixtures or tooling design experience
Experience with automation, robotics, or motion systems
Familiarity with Siemens NX or similar CAD software
Experience with fluid systems, alignment procedures, or precision mechanical assemblies

Responsibilities

Own the full mechanical build of our Poseidon robotic systems from start to finish
Develop new processes for new production required by new product development
Assemble, integrate, and debug electro-mechanical subsystems including actuators, motors, PCBs, plumbing, and structural assemblies
Identify design issues during build and work directly with the design team to implement improvements
Build fixtures, tools, and processes that make each unit faster and more reliable to assemble
Diagnose failures quickly through teardown, root-cause analysis, and hands-on testing
Ensure every Poseidon unit meets quality, fit, alignment, and performance standards before deployment
Collaborate with technicians and engineers to improve the repeatability of every subsystem
Maintain build documentation, assembly procedures, and checklists as systems evolve
Help plan and execute the build infrastructure and processes needed to triple robot production in 2026
Work closely with design engineers to influence new revisions based on real build-floor feedback
