Monte Carlo Developer (Radiation Transport) (HSE-RP-CS-2025-53-GRAP)

Job Description

Your responsibilities

The Radiation Protection group, within the HSE Unit, is participating in the development of the FLUKA Monte Carlo radiation transport code. FLUKA has a wide range of applications, spanning accelerator design and shielding, radiation protection, particle physics, dosimetry, detector simulation, hadron-therapy. At present the existing codebase is extended while in parallel a completely new generation of the code is being developed using state-of-the-art software development techniques in C++.

Responsibilities:

• Work in the code development team that integrates various members from the Radiation Protection (HSE-RP) & the Sources, Targets & Interactions group (SY-STI-BMI)
• Extend existing and develop new features that are of high interest to the Radiation Protection community (biasing based on statistical learning, activation calculations, delayed radiation calculations, etc.)
• Help debugging problems and participate in the support of the user community (https://fluka-forum.web.cern.ch/

If you're passionate about stochastic modelling, advanced statistics, numerical methods in C++ and pushing the forefront of radiation transport simulations, we encourage you to apply. Join us shaping the next generation of FLUKA.

About us

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.
