SLAC National Accelerator Laboratory is one of 17 Department of Energy (DOE) National Laboratories, and operated by Stanford University on behalf of the DOE. SLAC develops and operates some of the world’s premier science facilities, including the first hard X-ray free-electron laser. Research at SLAC explores the structure and function of matter and the properties of energy, space and time, at the smallest and largest scales, all with the goal of solving problems facing society and advancing human knowledge.

 

 


Staff Engineer 2 – [Controls and Automation Engineer]

Job Requisition #: 2863
Classification Title: Staff Engineer 2
Grade: K
Location: Menlo Park, CA (HQ)
# of openings: 1

Description

POSITION OVERVIEW:

Do you enjoy collaborating with a diverse group of people to solve complex challenges?  Does contributing to breakthrough discoveries in science and working with unique experimental instrumentation in a world-leading scientific research environment excite you? The Photon Controls and Data Systems (PCDS) Department within the Linac Coherent Light Source (LCLS) Directorate at SLAC is seeking a PLC Controls & Automation Engineer to plan, implement, and operate customized experimental installations, and develop enhancements to our scientific instrumentation and supporting hardware and software for PLC-based controls & automation systems.

 

Reporting to the Automation Group Lead, the Controls and Automation Engineer  will be a member of a multidisciplinary team comprised of electronic engineers and software developers focused on developing software and hardware solutions to support scientific instrumentation, laser systems, controls, and data acquisition systems.  This position will also work with scientific and operations support staff involved in advancing scientific instrumentation capabilities.

 

LCLS is the world’s first hard x-ray free electron laser (FEL) with unprecedented capabilities in photon energy range, peak power, and pulse lengths. There are seven independent instruments currently in operation, which are specifically designed to utilize the exceptional beam characteristics of the LCLS to probe the structure and dynamics of matter at atomic size and timescales.  The evolution of science and experimental techniques on these instruments, along with upgrades in the x-ray FEL source and optical lasers (LCLS-II), require regular improvements to the supporting software and hardware platforms. Programmable Logic Controllers (PLC) form the backbone of some of the most vital experiment support systems at LCLS, ranging from robust vacuum control to monitoring & protection of sensitive machine components, to motion control in steering x-ray optics. Additionally, the LCLS-II superconducting upgrade to the accelerator brings new capabilities, equipment, and infrastructure to the experiments that must be designed, developed, and installed prior to first light.  See https://portal.slac.stanford.edu/sites/lcls_public for more on LCLS and the unique capabilities of our instrument facilities.

 

CORE DUTIES :

  • Manage hardware and software for the PLC controls & automation systems and related infrastructure such as computers and local networks, power supplies, motion systems, vacuum systems, and the like.
  • Participate in upgrades to, and new designs involving, PLC controls & automation systems for vacuum systems, power systems, facility monitoring, pneumatics, cooling, fieldbus networks, mechatronic systems, and similar.
  • Lead the development and support effort for the LCLS PLC programming and development environment, and ensure that collaborative capabilities and a robust development process are maintained and extended as necessary.
  • Develop system specifications and designs to meet stakeholder needs.
  • Produce BoMs and schematic outlines, and be responsible for ensuring successful and on-schedule delivery of a fully commissioned instrument control system from actuator to user interface (HMI).
  • Define, implement, and execute reliability and qualification tests. Design electronic test benches; perform safety and reliability analysis and tests, and develop documentation.
  • Diagnose issues identified in control systems in operation, with subsequent follow-up solutions and recommendations for improvement.
  • Investigate new PLC and automation technologies.
  • Provide expert level support for PLC operations.
