Position Overview \n
Are you a software engineer motivated by building applications that power scientific discovery? 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 Software Developer to join the Engineering and Design controls team. The Software Developer will primarily develop and maintain Python and C/C++ based applications and automation scripts that serve as an important interface for controlling complex experiments to advance scientific research.
\n
LCLS is the world's first hard x-ray free electron laser (XFEL) with unprecedented capabilities in photon energy range, peak power, and pulse lengths. There are 8 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.
\n
As a member of the ECS Engineering and Design department, the Software Developer will join a multidisciplinary engineering group which develops and supports technology for controlling and operating scientific instrumentation at LCLS. This suite of instrumentation characterizes and delivers the XFEL beam to experiments and establishes the conditions for data collection. You will also help develop and deliver Python, C, and EPICS software for LCLS projects at varying scales.
