Applied Physicist for ATLAS Trigger Reconstruction (EP-ATL-OSW-2026-124-GRAP) Full‑time
The goal of this project is to introduce innovative selections into the ATLAS trigger system to improve the identification of events in difficult regions of the parameter space, including rare Standard Model processes and exotic signatures. In collaboration with NextGen doctoral students, the selected candidate will contribute to the development of the trigger menu for the High‑Luminosity Large Hadron Collider (HL‑LHC) era. The position is part of the Next Generation Trigger programme.
Your responsibilities
Design new triggering algorithms and strategies, including alternative data flows and ML/AI‑based approaches.
Develop tools to support HL‑LHC trigger menu studies.
Simulate trigger selections and estimate trigger rates using data and HL‑LHC Monte Carlo samples.
Ensure that proposed solutions meet trigger menu constraints on processing resources and rate limits.
Implement solutions within the central ATLAS trigger software.
Collaborate closely with ATLAS trigger and TDAQ upgrade experts.
This role includes team supervision responsibilities.
Your profile
Strong background in collider physics.
Experience with AI/ML and trigger systems.
Skills
Strong software skills
Excellent communication and presentation skills.
Experience with, or willingness to supervise, students.
Spoken and written English, with a commitment to learn French.
Eligibility criteria
You have a professional background in PhD in Physicsor 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.
Contract duration: 24 months, with a possible extension up to 36 months maximum.
Working hours: 40 hours per week
Job flexibility: Fully Onsite
This position involves:
Work during nights, Sundays and official holidays, when required by the needs of the Organization.
Field of work: Experimental Physics
Benchmark job: 200140 - Applied Physicist
A monthly stipend between 6372-7004 Swiss Francs per month (tax free) depending on your degree.
30 days of paid leave per year plus 2 weeks annual closure.
Coverage by CERN’s comprehensive health insurance scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund.
Family, child and infant monthly allowances depending on your individual circumstances.
A relocation package (installation grant and travel expenses) depending on your individual circumstances.
Possibility to extend your contract up to 36 months.
On‑the‑job and formal training including language classes.
