Decode blueprints, sketches, parts lists, and assembly diagrams.
Understand and apply Geometric Dimensioning and Tolerancing standards, including:
Identify and understand the symbols and terminology that comprise datum reference frames, datum features and feature controls describing form, orientation, size and location, to correctly decode drawings and leverage this knowledge into precisely manufactured components.
What is Required:
Extensive 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.
Ability to climb stairs and ladders, and lift 23 kg (50 lbs.).
Good verbal and written communication skills.
Additional Desired Qualifications:
AS 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 is preferred.
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.
General personal computer application skills with spreadsheets, databases and word processors.
The posting shall remain open until the position is filled.
This is a full time career appointment.
Full-time, M-F, non-exempt (hourly paid) from overtime pay.
This position is represented by a union for collective bargaining purposes.
Salary will be determined based on range by collective bargaining agreement.
This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.
Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA.
Berkeley Lab (LBNL) addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the U.S. Department of Energy's Office of Science.

In the world of science, Lawrence Berkeley National Laboratory (Berkeley Lab) is synonymous with excellence. Thirteen scientists associated with Berkeley Lab have won the Nobel Prize. Fifty-seven Lab scientists are members of the National Academy of Sciences (NAS), one of the highest honors for a scientist in the United States. Thirteen of our scientists have won the National Medal of Science, our... nation's highest award for lifetime achievement in fields of scientific research. Eighteen of our engineers have been elected to the National Academy of Engineering, and three of our scientists have been elected into the Institute of Medicine. In addition, Berkeley Lab has trained thousands of university science and engineering students who are advancing technological innovations across the nation and around the world. Berkeley Lab is a member of the national laboratory system supported by the U.S. Department of Energy through its Office of Science. It is managed by the University of California (UC) and is charged with conducting unclassified research across a wide range of scientific disciplines. Located on a 200-acre site in the hills above the UC Berkeley campus that offers spectacular views of the San Francisco Bay, Berkeley Lab employs approximately 4,200 scientists, engineers, support staff and students. Its budget for 2011 is $735 million, with an additional $101 million in funding from the American Recovery and Reinvestment Act, for a total of $836 million. A recent study estimates the Laboratory's overall economic impact through direct, indirect and induced spending on the nine counties that make up the San Francisco Bay Area to be nearly $700 million annually. The Lab was also responsible for creating 5,600 jobs locally and 12,000 nationally. The overall economic impact on the national economy is estimated at $1.6 billion a year. Technologies developed at Berkeley Lab have generated billions of dollars in revenues, and thousands of jobs. Savings as a result of Berkeley Lab developments in lighting and windows, and other energy-efficient technologies, have also been in the billions of dollars. Berkeley Lab was founded in 1931 by Ernest Orlando Lawrence, a UC Berkeley physicist who won the 1939 Nobel Prize in physics for his invention of the cyclotron, a circular particle accelerator that opened the door to high-energy physics. It was Lawrence's belief that scientific research is best done through teams of individuals with different fields of expertise, working together. His teamwork concept is a Berkeley Lab legacy that continues today.
