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 https:// home.cern.
The Engineering Department (EN) pushes back the limits of technology so that
physicists can carry out their research. Within the Mechanical & Material
Engineering Group (MME) of the EN department, you will join the Materials,
Metrology and Non-Destructive Testing (MM) section EN-MME-MM, more
specifically the dimensional metrology laboratory that undertakes the
inspection of parts, components and assemblies from small items to large
units. This includes dimensional measurements with various cutting-edge
equipment such as CMM (Coordinate Measuring Machines), 3D laser scanners and
an X-ray Computed Microtomography (µCT) unit.
As a dimensional metrology engineer, you will be in charge of the definition
of the measurement techniques taking into account all the parameters and
characteristics of the inspection, including the accuracy and measurement
uncertainty. In addition, you will have the opportunity to get involved in the
whole lifecycle of mechanical fabrication of components for CERN particle
accelerators, from development and production to integration operations and
Are you passionate about high quality manufacturing? Are you skilled in
combining mechanics, assembly, creativity, measurements, and rigour? This is
an opportunity for you: you will be part of a multidisciplinary team
fabricating the large variety of parts and units used at CERN, in the
framework of a wide range of research and development projects. Join a highly
qualified team of engineers and technicians in measurement processes. CERN,
As part of a group of specialists, you will mainly carry out geometrical and
dimensional measurements, namely:
Be responsible for predicting the needs of inspection methods and
implementing metrology features to the conceptual design study during the
design and manufacturing phase of the projects;
On the basis of the parts to be conceived, evaluate and select the
appropriate measurement methods and the required tools in view of
performing final measurements and quality inspections;
Perform quality control and final dimensional inspection of parts for
actual and future CERN accelerators and experiments, whether manufactured
on-site or off-site;
Perform quality control and high-precision metrology inspections, using
conventional tooling for dimensional certification, numerically controlled
3D CMMs and ultra-precise non-contact 2D and 3D laser operated measuring
machines. Portable measuring apparatus (3D scanners, poly-articulated
measuring arm and conventional portable measuring tooling) may also be
Produce relevant documentation and reports of results obtained on the
measured parts for subsequent presentation to the users;
Collaborate with sub-contractors on the acceptance, intermediate quality
control and dimensional checking of components during production. This
will involve occasional travel within the Member States;
Keep abreast of developments in international standards on quality
control, develop and maintain measurement procedures and templates.
Master's degree or PhD or equivalent relevant experience in the field of
Mechanical Engineering or a related field.
Proven experience in high precision metrology and quality control of
advanced mechanical components;
Experience in programming and operation of computer-aided metrology
Experience with portable volume measurement instruments and methods;
Proven hands-on experience of conventional measurement instruments and
Experience in developing and documenting standard or non-standard test
procedures and calibration protocols.
Experience in design and manufacturing work would be an advantage.
Knowledge and application of advanced metrologic techniques: (micrometric
3D and proficiency in 3D metrology software; optical metrology; knowledge
of surface metrology and standards including roughness measurements; good
knowledge of state-of-the-art dimensional metrology technologies and
processes; knowledge of the market in the metrology equipment field would
be an advantage)
Knowledge and application of conventional dimensional metrology
Manufacturing of mechanical parts: (ability to interpret engineering
drawings in accordance with ISO GPS standards; knowledge of precision
Achieving Results: having a structured and organised approach towards
work; being able to set priorities and plan tasks with results in mind
Driving work / projects along and seeing them through to their conclusion
Demonstrating Accountability: working conscientiously and reliably;
delivering on promises
Solving Problems: addressing complex problems by breaking them down into
manageable components Assimilating large quantities of information,
identifying key issues and formulating conclusions clearly and concisely.
Communicating Effectively: ensuring that information, procedures and
decisions are appropriately documented
Working in Teams: cooperating constructively with others in the pursuit of
team goals; balancing personal goals with team goals. Building and
maintaining constructive and effective work relationships
Spoken and written English or French: ability to understand and speak the
other language in professional contexts. Ability to draw-up technical
specifications and/or scientific reports and to make oral presentations in at
least one of the two languages.
