Postdoctoral Associate

Job ID JR100592 Date posted 09/29/2023

The Nuclear and Particle Physics Software (NPPS) Group in the Physics Department at BNL participates in BNL’s nuclear and particle physics experiments and programs such as the ATLAS experiment at CERN, the Belle II experiment at KEK, and the sPHENIX experiment at BNL, among 10 in total. BNL is the site of the future Electron Ion Collider (EIC) and NPPS plays leading roles in EIC software development.

The NPPS Group has an opening for a postdoctoral associate position to work on EIC software development with a particular focus on detector simulation. The selected candidate will play a central role in advancing the detector simulation infrastructure to be used in the EIC experimental program, including the newly formed ePIC detector and an anticipated future second detector. The work will encompass fully detailed as well as fast (e.g. parameterized, ML based, and/or GPU accelerated) simulation within a Geant4 based infrastructure, with an advanced python interface for ease of configuration and use. A focus of the work will be on simulation needs of EIC detector systems being developed at BNL, in particular RICH detectors. The position is likely to involve extending effort and expertise to other experiments as well over time.

The successful candidate will be experienced in nuclear and/or high energy physics software development. We are seeking a physicist with strong software skills and an interest in a scientific software career path, individuals prepared to work full time on software. This position has a high level of interaction with an international and multicultural scientific community.

Essential Duties & Responsibilities

  • Scientific software development for nuclear and high energy physics experiments that are part of the NPPS program
  • Play a central role in developing and using detector simulation software (both fully detailed and fast simulation) and associated infrastructure in the EIC experimental program
  • Leverage EIC software and experience to make contributions to other BNL experiments
  • Contribute to common software efforts across experiments, an example being the common use of simulation software across EIC experiments, and providing common developments to the wider high energy and nuclear physics detector simulation community. 

Required Knowledge, Skills, and Abilities:

  • PhD in experimental particle or nuclear physics
  • Experience in particle or nuclear physics software development and computing
  • Demonstrated strong programming skills in C++
  • Knowledge of major HEP software packages including Geant4 and ROOT
  • Experience in collaborating with a distributed team of scientists and software developers
  • Research experience demonstrated through a record of publications in peer-reviewed journals
  • Proven ability for disseminating research results by writing manuscripts and giving academic presentations

Preferred Knowledge, Skills, and Abilities:

  • Experience in developing and applying detector simulation software in the design and operation of particle or nuclear physics detectors
  • Experience in applying machine learning to scientific problems
  • Demonstrated strong programming skills in Python
  • Experience in parallel programming and heterogeneous computing (e.g. GPUs)


  • This is an on-site position eligible for consideration of flexible work arrangement (hybrid telework) at the discretion of the manager/dept chair.
  • Initial 3-year term appointment subject to renewal contingent on performance and funding. Domestic and some international travel is anticipated
  • This position will be under the direction of Dr. Torre Wenaus, NPPS Group Leader
  • Expected start date is immediate

Brookhaven Laboratory is committed to providing fair, equitable and competitive compensation. The full salary range for this position is $68400 - $113250 / year.  Salary offers will be commensurate with the final candidate’s qualification, education and experience and considered with the internal peer group. Position level & salary will be commensurate with experience and qualifications

Brookhaven employees are subject to restrictions related to participation in Foreign Government Talent Recruitment Programs, as defined and detailed in United States Department of Energy Order 486.1A. You will be asked to disclose any such participation at the time of hire for review by Brookhaven. The full text of the Order may be found at:
