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 invites applications for a Motion Controls Engineer opportunity. The position is responsible for supporting controls software for the Advanced Light Source (ALS), a world-class user facility that provides high intensity photon beams for science. This position has a special emphasis on design and support of high precision motion controls, requiring knowledge of motion controls software and hardware. This position will be filled at Level III or Level IV, dependent on experience.

Level III - Specific Responsibilities:

*

Design, develop, maintain and upgrade control systems including software and occasionally hardware, with a specific focus on motion control systems.
*

Support motion controls at the ALS for continued highly reliable performance.
*

Troubleshoot and maintain the Delta Tau controllers, including PMAC and Power PMAC models. Maintain the existing EPICS interface to the Delta Tau controllers. Design and develop improvements to the PMAC code to meet ongoing institutional needs.
*

Regularly interface with a variety of personnel to determine needs and performance of the system, including accelerator physicists, beam line scientists, mechanical engineers, and software engineers.
*

Conduct occasional training sessions on the operation, troubleshooting and maintenance of the control systems software and associated equipment.
*

Provide complete and professional documentation of all aspects of the system including software, system configuration, and troubleshooting.
*

Participate in the specification and design of new devices in close cooperation with mechanical engineers and scientists to ensure the proper system implementation.
*

Support the activities of the controls group in ensuring the reliable operation of and improvements to the entire accelerator control system.
*

Provide occasional off-hours support when needed to install, troubleshoot and repair control systems.

In addition to the above, the Level IV will:

*

Solve highly technical and complex problems and to provide input and direction to project-related decisions.
*

Determine methods and procedures on projects and may provide guidance to personnel.
*

Take a lead role in designing, implementing and/or administering the control systems at the ALS.

Level III - Required Qualifications:

*

Bachelors degree in Computer Science, Electrical Engineering or Physical Sciences plus a minimum of 5 years of directly related experience, or the equivalent combination of education and experience.
*

Knowledge of EPICS, the Experimental Physics and Industrial System.
*

Motion controls experience including PID tuning and encoder feedback.
*

Experience with motion controllers such as Delta Tau, Galil, etc.
*

Software development experience in both Linux and Windows environments.
*

Demonstrated experience in software and hardware development of controls and data acquisition systems, programming in C/C , designing, writing and maintaining software that interfaces with controls hardware.
*

Proven experience utilizing modern coding standards, including well-documented code, source code control, debugging and testing tools.
*

Ability to work with minimal supervision on complex projects, and willingness to actively seek support from appropriate experts.
*

Effective interpersonal skills, clear, proactive communication with the ability to communicate and collaborate with colleagues with varying skills and backgrounds including accelerator operators, physicists, and mechanical, electronic and software engineers.

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

*

Additional minimum of 8 years directly related experience.
*

Thorough knowledge of EPICS, including experience writing IOCs and support modules.
*

Extensive experience with motion controllers including Delta Tau, including programming the PMAC and/or Power PMAC API.
*

Demonstrated experience with sophisticated motion control algorithms.
*

Leadership skills on technical projects, including mentoring and instructing coworkers, creating cost estimates, schedules and proposal presentations.
*

Ability to represent the Lab to the community by, for example, giving presentations at conferences, collaborating remotely with colleagues at other institutions, and contributing to open-source software projects.
