Mechanical Test Technician

System One is seeking a Mechanical Test Technician to support advanced engineering and testing activities within the nuclear energy sector. This role is ideal for hands-on, detail-oriented technicians who enjoy working closely with engineers and scientists to support prototype development, mechanical testing, and experimental systems in a regulated environment.

Position Summary

The Mechanical Test Technician will independently perform a wide range of technical tasks in support of mechanical testing campaigns. The role involves collaboration with engineers, scientists, machinists, and other technicians to design, fabricate, assemble, operate, and test components, subassemblies, vessels, piping systems, and experimental prototypes.

This position requires strong hands-on mechanical aptitude, the ability to operate sophisticated test equipment, and experience collecting and evaluating test data to support prototype adjustments and test execution.

Onsite presence is required at the Bellevue or Everett, WA locations.
The expectation is a minimum of three (3) days onsite per week, with some project phases requiring full-time onsite support (five days per week) depending on testing and program needs.

Key Responsibilities

• Execute hands-on mechanical testing campaigns in accordance with approved procedures

• Perform work in compliance with safety, quality, and regulatory guidelines

• Support design, procurement, fabrication, installation, troubleshooting, and repair of test equipment and engineering infrastructure

• Assist with laboratory maintenance, organization, and cleanup

• Repair and maintain mechanical equipment and systems

• Collaborate with internal stakeholders to translate conceptual requirements into test specifications, including instrumentation strategies and success criteria

• Define, select, and validate measurement instrumentation (e.g., load cells, LVDTs, encoders, RTDs, strain gauges, temperature sensors)

• Coordinate cross-functional efforts including fixture design, control system integration, and lab space planning

• Manage test campaigns from concept through execution and reporting, including setup, validation, and post-test analysis

• Support testing activities that may require working at elevated heights (typically under 60 feet)

• Under guidance of senior engineers, assist with setup and commissioning of experimental equipment

• Apply nuclear industry best practices and support continuous improvement initiatives

Qualifications & Skills

• High School Diploma or GED (required)

• 2- or 4-year technical degree (preferred)

• Minimum 4 years of experience in test operations (nuclear, aerospace, military, or industrial)

• Relevant school or military experience may substitute

• Basic math skills including algebra, fractions, percentages, and unit conversions

• Knowledge of pumps, electric motors, motor controls, piping systems, hydraulic systems, and mechanical equipment

• Proficiency with personal computers and standard software (Word, Excel, spreadsheets, control system interfaces)

• Ability to accurately perform, document, and report laboratory test results

• Ability to read and interpret engineered drawings

• Ability to read meters and gauges accurately

• Understanding of electrical, radiological, and chemical hazards and safety practices

• Strong interpersonal and communication skills

• LabVIEW experience is a plus

Physical & Work Requirements

• Ability to sit and/or stand for extended periods

• Bending, stooping, grasping, gripping, and fine motor control required

• Ability to safely lift up to 25 pounds

• Repetitive work and visual/audio focused tasks

• Work environment may include stairs, typing/keyboard use, and extended workdays (>8 hours)

• Travel: 0–5%
