Job Description

Senior Mechanical Technician

Pleasanton, CA

We're working with an innovative hardware technology company developing advanced defense systems, and we're looking to appoint a Senior Mechanical Technician at its Pleasanton facility.

This is an opportunity to join a growing engineering team working on complex, high-performance hardware where mechanical craftsmanship, precision manufacturing and reliability are fundamental to the end product.

The role will suit an experienced, hands-on technician who enjoys working across machining, fabrication, mechanical assembly and hardware testing, taking components from engineering drawings through to fully assembled and qualified hardware.

What you'll be doing:

• Operate manual mills and lathes to machine components, produce fixtures and tooling, and carry out fast-turn modifications.
• Build and assemble mechanical enclosures, chassis, mechanisms and integrated electromechanical assemblies.
• Work with precision fasteners, torque specifications, O-rings, gaskets, adhesives and environmental sealing techniques.
• Prepare and instrument hardware for environmental qualification testing, including vibration, shock, thermal, rain, dust and salt-fog testing.
• Support test execution, inspections and hardware teardowns, identifying issues and feeding practical improvements back to engineering.
• Interpret engineering drawings and GD&T, carry out precision measurements and maintain accurate build and inspection documentation.
• Help establish repeatable assembly processes, workshop standards and quality practices.

Ideal Experience:

• 10+ years of hands-on mechanical, manufacturing or test technician experience.
• Background in aerospace, defense, space or similarly demanding hardware environments.
• Strong manual machining experience, particularly milling and turning.
• Proven mechanical assembly and fabrication skills.
• Experience reading engineering drawings and GD&T, using precision measurement equipment.
• Familiarity with environmental testing, ideally vibration, shock and thermal qualification.
• Exposure to AS9100 or comparable aerospace/defense quality systems.
• Someone comfortable working in a hands-on R&D environment, taking ownership and working closely with engineering teams.

Additional experience with CNC setup/programming, SolidWorks, 3D printing, welding or an active security clearance would be beneficial.

This is a full-time, on-site position in Pleasanton, California. Candidates must qualify as a U.S. Person under ITAR/EAR requirements.
