Missions

The Kastler Brossel Laboratory is looking to recruit a research engineer specializing in nano and microfabrication to lead projects involving the design, manufacture, and characterization of original devices at the micro- and nanometric scale. Working closely with several teams within the laboratory and in coordination with the various clean rooms in the Paris region to which the laboratory has regular access, the engineer will play a central role in developing processes tailored to scientific needs, structuring expertise, and enhancing the laboratory’s skills in the field of quantum technologies.

Activity

The engineer will join a high-level research environment within the laboratory’s “Quantum Information and Optics” division and will be involved in all stages of experimental device development, from design to implementation in the clean room.

• Design, manufacture, and characterize complex devices based on nano- or micro-manufacturing processes in clean rooms; develop new devices, from the substrate to the complete packaging.
• Study scientific needs, propose solutions, and develop new manufacturing and characterization processes.
• Negotiate functional specifications and draft technical specifications.
• Organize the monitoring of the project’s progress, validate and qualify the device at its various stages.
• Manage all technical and financial resources allocated to projects, including orders and the storage of consumables.
• Ensure access to and coordination with clean rooms in Paris and the Paris region; liaise with the various clean room managers.
• Keep up to date and receive training as necessary on the equipment used in clean rooms.
• Monitor technological developments; maintain and enhance in-house design/simulation software.
• Present, disseminate, and promote achievements.
• Participate in promotion projects involving nano- or micro-manufacturing.
• Advise, train, and inform researchers working in clean rooms on the principles and implementation of manufacturing and characterization processes; ensure safety and compliance with rigorous scientific methods.

Profile

Expertise:

• Techniques in the field of nano and micro-manufacturing: laser and electron lithography (20 keV and 100 keV), plasma etching (RIE, ICP-RIE), FIB… (in-depth knowledge).
• Engineering techniques and sciences (optics, microwaves, electronics, programming, mechanics, chemistry) (general knowledge).
• General physics and physics in the relevant field (radiation, matter, thermodynamics, etc.) (general knowledge).
• Environment and professional networks (general knowledge).
• Written and oral presentation techniques.
• English language: B1 to B2 (Common European Framework of Reference for Languages).

Skills:

• Combine a set of elements from different technological fields.
• Manage a project.
• Use field-specific software.
• Lead a meeting.
• Conduct negotiations.
• Apply quality assurance procedures.
• Apply health and safety rules.
• Manage a budget.
• Apply public procurement regulations.
• Monitor technological developments.

Environment

The Kastler Brossel Laboratory (LKB) is a joint research unit of the French National Center for Scientific Research (CNRS), the École Normale Supérieure (ENS), Sorbonne University (SU), and the Collège de France. Internationally renowned in the field of quantum physics, it comprises 11 research teams and several administrative and technical departments, involving nearly 200 people. The laboratory is spread across three sites in Paris (ENS, SU, and Collège de France), but the position will be based at Sorbonne University (SU).
The position is part of the “Quantum Information and Optics” research area, which brings together several teams developing original experimental devices requiring advanced micro- and nanofabrication processes. These devices include superconducting circuits, optomechanical resonators, optical nanoguides, and hybrid photonic structures.

The engineer recruited will play a central role in structuring this cross-disciplinary activity within the laboratory. He or she will ensure technical coordination with the various clean rooms in the Paris region (mainly ENS, INSP, Paris Cité, but also Collège de France, CEA, LPS Orsay, etc.), participate in the pooling and documentation of processes, contribute to user training, and ensure the continuity of know-how between generations of doctoral and post-doctoral students.

The position is part of a drive to enhance the LKB’s manufacturing capabilities, already supported by significant investments in shared equipment, and will enable the laboratory to play a full role in the ongoing developments in the field of quantum technologies.
