Berkeley Lab is Bringing Science Solutions to the World, and YOU can be a part of it!

In the world of science, Lawrence Berkeley National Laboratory (Berkeley Lab) is synonymous with "excellence." That's why we hire the best - whether in research, science or operations. This is a great opportunity to bring your top-notch skills to bear in support of world-class scientific research that addresses national and global challenges!

Position Summary:

Berkeley Labs Engineering Division is looking for a Machinist (Mechanical Engineering) to provide technical support in the field of journey-level machining technology. You will apply intermediate-level knowledge, innovation, and creativity in mechanical and shop related theory and practice. This position will be filled at the Mechanical Engineer Machinist (Level II or Level III), dependent on experience.

Level II - Specific Responsibilities:

*

Under general supervision apply advanced knowledge and expertise in journey-level machining technology, theory and practice to effectively and efficiently carry out assignments.
*

Design and fabricate workpiece fixtures for one-of-a-kind or production machine tool fabrication of metallic or non-metallic parts.
*

Provide design for manufacturability advice to technicians, designers, engineers and scientists.
*

Use both conventional and Computer Numerical Controlled machinery to program, set-up and perform mixed-complexity machining operations that include producing hardware components and assemblies bearing complex geometry, high precision, non-prismatic features, hidden features and difficult to machine materials.
*

Use computers, in conjunction with Computer Aided Design/Computer Aided Manufacturing software applications

*

Access, view, import, export, measure, manipulate and construct native electronic drawings and solid models as well as generic file formats such as dxf and iges.
*

Apply appropriate and efficient tool/cutter path to geometry, proper machining sequences, spindle speeds and federates.
*

Generate, edit and transfer appropriate machine tool controller-specific part program instructions.

*

Decode blueprints, sketches, parts lists, and assembly diagrams.
*

Understand and apply Geometric Dimensioning and Tolerancing standards

*

Compare Datum Reference Frames to Datum Features for correct decoding.
*

Understand the symbols and terminology describing part feature form, orientation, size and location.

In addition to the above, the Level III will:

*

Under minimal supervision apply advanced knowledge and expertise in journey-level machining technology, theory and practice to effectively and efficiently carry out assignments.

Level II - Required Qualifications:

*

Demonstrate technical understanding of machining and related mechanical process theory and work practices typically acquired with a minimum of 5 years experience.
*

Demonstrate understanding of technical shop mathematics.
*

Conventional and CNC machine tool experience, performing work on complex, precision (to .0005 inch) hardware components and assemblies.
*

Experience with CAD and CAM applications.
*

Demonstrate knowledge, skill and work experience in performing set-ups, testing, troubleshooting, repair, calibration, operation and maintenance of sophisticated mechanical, shop related, and scientific apparatus, equipment and systems.
*

Demonstrate knowledge of and ability to select, set-up and use appropriate hand, power, and specialized machine tools.
*

Ability to read and correctly decode complex blueprints, sketches, parts lists, layout and assembly drawings and operation, calibration and repair manuals.
*

Ability to climb stairs and ladders, work from heights and confined spaces, and lift 23 kg (50 lbs.).

In addition to the above, the Level III will have:

*

Minimum of ten years experience in the field of machining precise, complex, one-off components, often of expensive and difficult to machine materials, using both conventional and CNC equipment.
*

Advanced understanding of machining theory, work practices and shop mathematics.
*

Extensive experience using CAM systems to analyze components, set-ups, tooling and fixturing, as well as to produce efficient, accurate toolpaths for use on a variety of CNC machine tools.
*

Ability to use CAD systems to manipulate electronic models of machined components and assemblies, as well as to model fixturing, tooling and machine tool components to aid in manufacturing processes.
*

Advanced understanding of the ISO 6983/RS274D machine tool programming language (G-code).
*

Extensive knowledge of the GD&T standard ASME Y14.5, with the ability to read and correctly decode complex blueprints, sketches, parts lists, layout and assembly drawings and operation, calibration and repair manuals.
*

Demonstrated knowledge of and ability to select, set-up and use appropriate hand, power, and specialized machine tools.
*

Demonstrated knowledge, skill and work experience in performing set-ups, testing, troubleshooting, repair, calibration, operation and maintenance of sophisticated mechanical, shop related, and scientific apparatus, equipment and systems.

Level II - Additional Desired Qualifications:

*

AA or BS degree in Mechanical Engineering Technology, Manufacturing Engineering Technology or Industrial Engineering Technology and/or successful completion of a formal machinist apprenticeship-program, or the equivalent in formal industrial training.
*

General personal computer application skills with spreadsheets, databases and word processors.

In addition to the above, the Level III will have these desired qualifications:

*

Experience with the programming, setup and operation of four and five axis machining centers, live tooling turning centers, wire and/or sinker EDM and rapid prototyping machines.
*

Experience in Fanuc Custom Macro B programming.

The posting shall remain open until the position is filled.

Notes:

*

This is a career appointment.
*

Salary is commensurate with experience.
*

Incumbents in this position are represented by a union for collective bargaining purposes.
*

This position requires completion of a background check.
*

Classification will depend upon the applicant's level of skills, knowledge, and abilities.
