About The Position

The Senior Mechanical Design Engineer provides hands-on mechanical and opto-electro-mechanical design support for complex experimental, pulsed power, high-voltage, accelerator, diagnostic, and other mission-critical hardware in research and production environments with Lawrence Livermore National Laboratory in Livermore, California. The role works closely with physicists, engineers, technologists, manufacturing personnel, and program staff to develop sophisticated hardware from early concepts through final design, documentation, procurement, fabrication, assembly, installation, and testing. The position requires strong capabilities in precision mechanical design, design definition, configuration-controlled drawing packages, GD&T, and manufacturing. The engineer works independently on fast-paced technical programs and may lead or check designers’ and detailers’ work while coordinating with fabrication vendors and internal stakeholders. The role is onsite and requires the ability to obtain and maintain a DOE Q clearance; a current DOE Q clearance is preferred.

Requirements

At least 15 years of progressively responsible experience in mechanical design, mechanical engineering technology, product design, or a related area supporting complex hardware.
Extensive hands-on experience with Creo/ProENGINEER and/or SolidWorks.
Ability to obtain and maintain the required clearance.

Nice To Haves

Expertise in GD&T and ASME Y14.5, engineering drawing development and checking, tolerance analysis, configuration control, and manufacturing methods.
Experience with pulsed power, high-voltage systems, accelerator technologies, diagnostics, experimental physics hardware, nuclear security programs, or other national laboratory R&D environments.
Experience with Windchill, PDMLink, ELM, or similar PDM/PLM systems and vendor fabrication/procurement.
Bachelor’s degree in mechanical engineering, engineering technology, design, manufacturing technology, or a related field; an equivalent combination of education and extensive relevant experience may be considered.
Current DOE Q clearance.

Responsibilities

Develop mechanical and opto-electro-mechanical designs for complex experimental, pulsed power, high-voltage, accelerator, and diagnostic systems.
Translate conceptual requirements from physics and engineering staff into detailed 3D models, assemblies, drawings, and released design packages.
Support hardware throughout the design lifecycle, including concept development, design reviews, documentation, procurement, fabrication, assembly, installation, and testing.
Apply GD&T and ASME Y14.5 principles, tolerance analysis, and design-for-manufacturing practices to precision hardware and assemblies.
Create, revise, check, and release CAD models and engineering drawings using Creo/ProENGINEER and/or SolidWorks within controlled PDM/PLM environments.
Coordinate with machine shops, fabricators, suppliers, and procurement personnel to obtain quotes, resolve manufacturing issues, track hardware, and meet project schedules.
Lead or coordinate the technical work of designers and detailers, perform design checks, and help ensure the quality and consistency of engineering deliverables.
Collaborate across mechanical, electrical, physics, controls, and manufacturing teams to resolve multidisciplinary design and integration challenges.
Support design reviews, configuration management, drawing release, installation activities, and continuous improvement of engineering and design processes.
