Precision Mechanical Assembly Technician

A day in the life

At our Sacramento, CA facility, you arrive to a clean, organized work cell, review the day’s build plan and blueprints, and begin bringing mechanical systems to life. You methodically assemble components to spec, verify tolerances, and record what you’ve completed. When something doesn’t align, you troubleshoot, confer with teammates, and fine-tune the process so the next build is even better. Throughout the day, you switch confidently between hand and power tools, keep your station orderly, and contribute ideas that elevate quality and throughput.
