Position Description:    

*** this position has been closed, and no new applications will be accepted. ***

The LUX-ZEPLIN (LZ) Dark Matter Group at SLAC has an immediate opening for a Software Developer to prepare for the upcoming science phase. LZ is a liquid xenon time projection chamber with a 7-ton active target that will provide unprecedented sensitivity to dark matter. The experiment will be located in the Davis Campus at the 4850’ level in the Sanford Underground Research Facility (SURF) with turn on in early 2020.

The SLAC group is responsible for a number of key LZ deliverables, including: offline software, reconstruction, and analysis tools; a system test program to verify detector components in gas and liquid xenon; custom woven mesh grids for the central detector; and a dedicated purification system to remove radioactive krypton from the target.

Computing resources for LZ are hosted at the National Energy Research Scientific Computing Center (NERSC). Data processing and data analysis employ the latest generation of supercomputers, including the Intel Xeon Phi Many Integrated Core Architecture. An upcoming refresh of the supercomputer platform will be based on a combination of CPUs and accelerators, opening the door to advanced machine learning techniques.

The focus of this appointment is to contribute to the development and optimization of the LZ software infrastructure and reconstruction framework. The successful candidate will oversee the optimization of the LZ software stack for the existing multicore architecture and prepare it for the next generation of supercomputers. The role includes membership in the LZ operations team, and key responsibilities over the data handling and data processing pipeline.

The ideal candidate will have a background of demonstrated excellence in computing and a MS or PhD in experimental particle physics, astronomy, computer science, or related field; or at least three years of relevant experience in software engineering. Familiarity with multicore computing, large-scale data handling, HEP software frameworks (ROOT, Gaudi, Geant4) and release engineering/continuous integration tools are highly beneficial. The initial appointment is for three years, with the possibility of extension for additional years or conversion to a regular continuing position upon satisfactory performance. Assignment duration is contingent upon project needs and funding.

Selection of candidates will start December 19, 2018 and will continue until the position is filled.
