About Us

The Particle Physics Department (PPD) at the Rutherford Appleton Laboratory (RAL) of Science and Technology Facilities Council (STFC), is one of the largest Particle Physics groups in the UK. We design, construct and operate some of the most sensitive scientific instruments in the world, collaborating with partners in academia, industry and international laboratories such as CERN. We currently work with the ATLAS, CMS, LHCb, DUNE, Hyper-K, T2K, MICE, Lux-Zeplin, DEAP-3600, CERN RD50, Electron Ion Collider and AION collaborations. The PPD ATLAS group plays a key role in the High Level Trigger (HLT), Level 1 Calorimeter Trigger and ITk projects, as well as physics data analysis.

About the role

Applications are invited for two physicists to join the ATLAS High Level Trigger (HLT) group within the Particle Physics Department (PPD). The PPD HLT group has long-standing experience and expertise on triggering and track reconstruction. The successful applicants will help maintain the operation of the current trigger during data taking and develop new triggers for the Phase II upgrade with an emphasis on fast track reconstruction and triggers exploiting track information. This will include developing tracking software for CPU and the use of accelerated computing technologies, GPUs and possibly FPGAs. In addition, you will be able to contribute to physics data analysis at the level of 10-20%.


  • A doctorate (DPhil or PhD) in experimental particle physics or a related field or be about to receive a doctorate in particle physics;
  • A strong background in programming with an emphasis on C++ and Python;
  • Experience with Linux;
  • An interest in the challenges of efficient computation;
  • Fluent English and good communication skills, both verbal and written, ability to work effectively with a wide range of scientists and project members;
  • Willingness to work at RAL and undertake travel to CERN and elsewhere.

Employee Benefits

We are offering a 3 year FTC with a whole host of benefits including:

  • 30 days holiday (in addition to 10.5 bank holidays and privilege days);
  • Flexible working hours;
  • An excellent defined average salary pension scheme;
  • Employee shopping/travel discounts;
  • Excellent learning and development opportunities.

We are committed to sustaining a diverse and inclusive workforce. We are invested in creating an environment that is welcoming and supportive of all, to help us achieve the highest possible standards in our work and organisation together. In this regard, we encourage applications from under-represented groups.

What could you achieve with the world-leading facilities and experts of one of Europe's largest research organisations by your side? Join us and discover what's possible.


STFC imageAt the Science and Technology Facilities Council (STFC), part of UK Research and Innovation (UKRI), research is driven by practical applications and a curiosity to create a world-leading hub of scientific and engineering excellence. Our science and facilities enable researchers to answer fundamental questions about the nature of the universe. Success typically requires long-term strategic investment, international collaboration on a global scale and the capability to push the limits of technology and engineering. To remain internationally competitive in our areas of science and to keep our facilities at the leading edge, we have to develop bespoke technology that cannot be reliably sourced on the open market, for example in detectors and instrumentation, accelerators, specialist engineering, optics and e-infrastructure. These technologies are often also applied to address broader societal and industrial challenges and we actively promote their translation and commercialization.

Why work for us
When you join STFC, you become a key part of one of Europe’s largest research organizations. We are trusted to support, enable, and undertake cutting-edge projects in an amazing diversity of fields that you could be a part of. With access to our world-class facilities, people like you are helping us to drive ground-breaking advances in science, engineering, computing and technology.
