Contexte de travail
The Laser Physics Laboratory (LPL) is an experimental physics research laboratory with approximately 90 staff members, including 55 permanent employees and 35 doctoral and post-doctoral students. Research topics include quantum gases, interactions between light and atoms or molecules, photonic devices, and precision measurements. These research activities are based on cutting-edge experimental developments that enable us to make scientific advances in highly competitive fields.
The successful candidate will work within the Metrology, Molecules and Fundamental Tests, which consists of 10 permanent researchers, lecturers and research engineers. Their activities, which are mainly experimental, focus on optical frequency metrology, ultra-precise molecular spectroscopy in the near and mid-infrared (NIR and MIR), and research on cold molecules. We use molecules to test fundamental physics, explore the limits of the standard model, and more generally to improve precision measurements and metrology research. To achieve these ambitious goals, we develop metrology-grade lasers, devices for ultra-high-resolution spectroscopy, and techniques for disseminating ultra-stable signals. In particular, we coordinate the national research infrastructure REFIMEVE (Réseau Fibré Métrologique à Vocation Européenne), with the LTE (national time-frequency metrology laboratory) and RENATER. This network of fibre optic links enables us to disseminate ultra-stable time and optical frequency signals throughout the country and to our European partners for a wide range of applications in fundamental metrology, precision measurements, photonics, earth sciences, etc. Our activities are therefore fundamental, applied (instrumental component) and service-oriented (REFIMEVE). We are also one of the five main partners of Labex First-TF.
The position offered is that of head of experimental development for precision measurements and ultra-stable signal transmission. This position is currently held by a research engineer who will retire in April 2026 and who will be able to train the person recruited. The profile sought is at the interface between an experimental development engineer specialising in metrology and an experienced electronics engineer. We are therefore looking for either an instrumentation development engineer with skills in analogue and digital electronics, or an expert electronics engineer with knowledge and skills in optics, metrology and physics. For electronic design and implementation, the successful candidate will be able to draw on the expertise of the laboratory's electronics engineers.
An external competition has been requested with a profile similar to that of this position.
