Full Job Description

Senior Mechanical Assembler
WET (Design) – Burbank, CA

At WET, we don’t just build systems—we engineer and manufacture complex, performance-driven environments that operate on a global stage. Our fountains and features, including the Fountains of Bellagio and the Dubai Fountain, integrate mechanical systems, controls, hydraulics, and show technology to deliver precision, reliability, and spectacle at scale.

We are seeking a Senior Mechanical Assembler who brings deep technical experience, strong mechanical intuition, and pride in craftsmanship. This is a critical, hands-on role responsible for building complex assemblies that must perform flawlessly in the field—often under demanding, real-world conditions.

Where You Fit In

As a Senior Mechanical Assembler, you will be at the center of building WET’s core systems—translating engineering designs into fully realized mechanical assemblies. You will work across mechanical structures, plumbing systems, and electrical integrations, ensuring each build meets exacting standards for fit, function, and durability.

This role is ideal for someone who has seen a wide range of assemblies, understands how systems come together holistically, and can independently drive work forward while supporting and elevating those around them.

What You’ll Do

Read and interpret complex engineering drawings, P&IDs, wiring diagrams, and assembly documentation
Assemble integrated mechanical systems including structural components, pipe assemblies, valves, manifolds, and electromechanical elements
Build and route wire harnesses and cable assemblies, ensuring proper termination, labeling, and protection
Perform plumbing and pipe fitting (threaded, compression, and bonded connections), ensuring leak-free and field-ready systems
Install and align pumps, motors, actuators, sensors, and lighting components to precise tolerances
Use precision tools including torque wrenches, calipers, micrometers, and alignment tools to verify assembly accuracy
Chase, repair, and maintain threads using taps, dies, and thread restoration techniques
Perform functional testing, troubleshooting, and rework to ensure assemblies meet performance requirements prior to release
Identify build issues, tolerance stack-ups, and design gaps; provide feedback to engineering and manufacturing teams
Support continuous improvement efforts, helping refine build processes, tooling, and assembly standards
Maintain a disciplined, clean, and safe work environment aligned with 5S and shop best practices

What You Bring

7+ years of hands-on experience in mechanical assembly within manufacturing, industrial, aerospace, or custom fabrication environments
Strong experience with mechanical systems, plumbing/pipe fitting, and wire harness assembly
Ability to read and interpret detailed engineering drawings, schematics, and technical documentation
High level of proficiency with hand tools, power tools, and precision measurement equipment
Solid understanding of tolerances, alignment, sealing methods, and system integration
Experience assembling complex, multi-disciplinary systems (mechanical + electrical + fluid systems)
Strong troubleshooting skills and the ability to identify and resolve issues during build
Self-directed, reliable, and able to take ownership of critical assemblies from start to finish
Effective communicator who can work cross-functionally with engineering, fabrication, and production teams

Preferred Experience

Experience in low-volume, high-complexity builds or custom engineered products
Background in themed entertainment, aerospace, automotive prototypes, or similar industries
Familiarity with hydraulic or fluid systems, pumps, and control assemblies
Experience supporting installation or field commissioning efforts

Why WET

At WET, your work is not hidden inside a product—it becomes part of a living system experienced by millions. The assemblies you build must not only meet spec, but perform reliably in highly visible, high-expectation environments.

This is a role for someone who takes pride in precision, ownership, and execution—someone who understands that the quality of their work directly impacts the performance of world-class installations.

If you’re a highly skilled assembler looking to apply your craft to something truly unique and technically demanding, WET offers the opportunity to build at a level few environments can match.

If you want, I can also calibrate this for pay transparency, union/non-union alignment, or tweak language to better target aerospace vs entertainment talent pools.
