Job type: Full Time · Department: Mechanical · Work type: On-Site · USD 125,000-175,000 / two weeks

El Segundo, California, United States

What You Get To Do:

  • 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

What You Will Need:

  • 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

Bonus Qualifications:

  • 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

Other Things To Know:

  • Expect to work long hours outside of standard business hours, including early mornings, evenings, and weekends to support testing activities, technician schedules, and production deadlines

  • 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
