Job 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 Experiment Control Systems (ECS) division within the Linac Coherent Light Source (LCLS) Directorate at SLAC is seeking a Laser Safety Systems Engineer to exercise responsibility for SLAC and LCLS Laser Safety Systems. LCLS Laser Engineering Department is responsible for the development, implementation, and maintenance of Laser Systems throughout the SLAC complex. The candidate will concentrate on the specification, hardware and software design and implementation of all Laser Safety Systems at the Lab. The successful candidate will establish performance criteria, evaluate system architecture, design, validate, document, implement, and exercise stewardship for the Laser Safety Systems. As the safety system engineer, you will perform project management and engineering work of considerable scope and complexity, often challenging and difficult with considerable technical independence as well as collaborate with LCLS and SLAC staff of diverse technical backgrounds to find solutions to the more challenging engineering problems. You will work with other engineers, engineering associates, and technicians, to support safety systems implementations and best practices, while maintaining and upgrading subsystems assigned. This position reports to the Laser Engineering Department Head.
See https://lcls.slac.stanford.edu/ for more on LCLS and the unique capabilities of our instrument facilities.

Your specific responsibilities include

• Own and maintain PLC and wired interlock-based Safety Systems. Systems range from relay-based interlock to legacy PLC installations, to modern industry standard PLC implementations.
• Design, review, plan, and implement upgrades to systems owned by the Laser Safety Program to maintain a high level of user availability. The Laser Safety Engineer is responsible for all aspects of system deployment.
• Collaborate with other related SLAC safety systems groups
• Assure rigorous work planning and control are in place including: project planning, requirements gathering, design reviews, soft/firmware version control, test procedures, management reports.
• Stewardship of LSS (Laser Safety Systems).
• Plan and implement upgrades to be the least invasive to 24/7 operations, with consideration of limited resources.
• Communicate with people from all other disciplines: Physicists, scientists, duty operators, electrical and mechanical engineers, electronic and network technicians.
• Hold and participate in safety systems reviews.
• Respond for occasional 24/7 support for system owned by the Laser Engineering Group.

To be successful in this position you will bring

• Bachelor of Science in Electrical Engineering, Physics, or Computer Engineering and 5 years of experience.
• PLC based interlock system design, implementation, and support
• Hardware Experience using various PLC specific system designs.
• Hardware Experience using fault-tolerant, standard program PLC and HMI & GUI designs.
• Proficiency reading electrical schematics and troubleshooting systems.
• Proactivity in creating and maintaining documentation related to projects, software, user guides, how-tos, among others.
• Lead and direct multiple complex projects requiring high levels of functional integration.
• Experience with version control systems, particularly Git, and collaborative development workflows
• Experience performing end-to-end ownership of tasks, including project management, schedule, and stakeholder management.
• Experience working in cross-disciplinary teams or environments.
• Effective communication (written and verbal).

In addition, preferred requirements include

• Experience designing, engineering, and implementing safety instrumented systems in alignment with functional safety standards
• Experience with relay logic implementation.
• Experience with Structured Text programming of PLCs
• Python, Linux, and EPICS (Experimental Physics and Industrial Control System) experience
