Job Description
Join the ATLAS Trigger and DAQ system as part of the Next-Generation-Trigger project to work on the Global Hardware Trigger, an upgrade that will be deployed for the High-Luminosity LHC programme for real-time data processing and event filtering using state-of-the-art field programmable gate arrays (FPGAs).
Take an active role in developing algorithms and infrastructure, including novel system-on-chip architectures capable of high-speed Machine Learning (ML) inference, to make optimal use of the available information from the calorimeter and muon systems for deriving the decision of this first step in the event selection chain of ATLAS.

Your profile:
Job closing date: 16.12.2025 at 23:59 CET.
Contract duration: 24 months, with a possible extension up to 36 months maximum.
Working hours: 40 hours per week
Job flexibility: Fully Onsite
Target start date: 01-March-2026
This position involves:
Field of work: Applied Physics
Benchmark job: 200140 - Applied Physicist
What We Offer
At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on http://home.cern.
We are on a Quest. A Journey into discovery like no other. Bring your expertise to our unique work and develop your knowledge and skills at pace. Join world-class subject matter experts on unique projects, in a Quest for greater knowledge and deeper understanding.

Your responsibilities:
- Develop and maintain pipelines for streamlining the end-to-end process of developing, optimising and implementing ML algorithms into the Global firmware framework, and supporting the ATLAS Global community in using these pipelines.
- Contribute to the Global hardware integration activities at CERN.
- Explore/develop/optimise novel ML algorithms for Global and play a leading role in developing the Trigger menu and strategy for the start of the HL-LHC programme.
- Explore/develop/optimise the concepts of anomaly detection, trigger-level analysis and data-scouting in ATLAS, using the Global system.
- Explore the potential/applicability of novel industry technologies for enhancing the reach of the Global system.
Your profile:
- Track record in developing novel ML algorithms.
- Background in computational statistics.
- Some experience with FPGA firmware development.
- Modern C++ and Python programming techniques.
- Writing and testing algorithms for data processing and filtering purposes.
- Knowledge of hardware description languages (HDL) or high-level synthesis (HLS) tools and concepts is highly desirable.
- Spoken and written English, with a commitment to learn French.
- You are a national of a CERN Member or Associate Member State.
- You have a professional background in Physics, Computer Science (or a related field) and have either:
- a Master's degree with 2 to 6 years of post-graduation professional experience;
- or a PhD with no more than 3 years of post-graduation professional experience.
- You have never had a CERN fellow or graduate contract before.
