Applied Physicist: Trigger system expert / software developer (EP-ADT-TR-2024-130-LD)

Introduction

Are you a physicist with extensive hands-on experience in trigger systems for a large High-Energy Physics experiment? Would you like to contribute to developing, maintaining and operating the system for one of the largest particle-physics experiments in the world?  Then apply for this post!

Functions

As Applied Physicist in the EP-ADT-TR Section, you will contribute to CERN’s responsibilities on the ATLAS Trigger Activity and the Trigger/DAQ System. You will be expected to work on a wide range of high-level trigger (HLT) topics, including: the development and maintenance of core software to support the HLT algorithms; integration of HLT algorithms in the software framework; testing, commissioning, operation and maintenance of the system; leading studies for improvements and upgrades; and supervision of fellows and students working on the HLT.

PhD or equivalent relevant experience in the field of Experimental Particle Physics or a related field.

Experience:

• Extensive experience in distributed, software based trigger systems for a large High-Energy Physics experiment, including: understanding requirements from a physics and technical perspective; and designing, developing, testing, commissioning, operating and maintaining trigger systems;
• Basic knowledge of software design principles and proven experience in object-orientated C++ and Python programming in a large, collaborative software project;
• It would be advantageous to have one or more of the following: experience in operating large scale trigger systems; experience with profiling tools to optimize the system performance; experience in using commercial computing accelerators (GPUs/FPGAs). 

Technical competencies:

• Simulation, design and development of trigger, data acquisition chains: experimental data reduction and triggering;
• Knowledge of programming techniques and languages: C++ and Python;
• Development of application software: multi-threaded, parallel, network-based programming focused on high-throughput, low-latency workloads, control and operation of PCIe devices;
• Capturing and analysis of requirements for ICT systems: requirements definition, design and management;
• Testing, diagnosing and optimization of software.

Behavioural competencies:

• Working in Teams: understanding when teamwork is required to achieve the best results; including others accordingly and sharing information
• Demonstrating Flexibility: demonstrating a willingness to accept changing circumstances; supporting initiatives for change;
• Solving Problems: assimilating large quantities of information, identifying key issues and formulating conclusions clearly and concisely;
• Learning and Sharing Knowledge: sharing knowledge and expertise freely and willingly with others; coaching others to ensure knowledge transfer.

Language skills:

Spoken and written English: ability to draw-up technical specifications and/or scientific reports and to make oral presentations.

Eligibility and closing date:

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success. We welcome applications from all Member States and Associate Member States.

This vacancy will be filled as soon as possible, and applications should normally reach us no later than 06.10.2024 at 23:45 CET
