Description

Company Description 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. Job Description Introduction: You will provide support to the Organisation in matters of Indoor Air Quality (IAQ) for occupational Health & Safety. This includes requirements for the design of air management systems, performing on-site workplace assessments and leading air quality studies for specific projects. Functions: Provide technical and safety requirements for the design and retrofit of ventilation and filtration systems. Conduct on-site workplace air quality assessments, measuring different indoor pollutants, analysing the results and proposing solutions. Investigate incidents related to air quality, perform root cause analysis, and recommend corrective actions. Lead complex Indoor Air Quality (IAQ) studies for high-risk and/or high-complexity projects. Perform ventilation / filtration rate calculations and airflow modelling. Develop IAQ guidelines, procedures, best practices and other engineering solutions for the Organisation. Act as Safety correspondent and become the single point of contact in matters of safety, for some CERN-specific projects. Qualifications Master's degree or PhD or equivalent relevant experience in the field of Mechanical Engineering or Environment and Building Engineering or a related field. Experience: Strong background in nuclear ventilation and ISO 17873 standard. Strong background on modelling the spread of pollutants in indoor environments. Experience with IAQ sensors and performing on-site measurements is desirable. Profound knowledge in Indoor Air Quality (IAQ) and Ventilation Standards. Knowledge in designing HVAC or air management systems for tertiary and industrial facilities. Familiarity with Python programming language and CFD tools is desirable. Technical competencies: HVAC process design and analysis. Occupational safety and risk management. Knowledge and application of numerical modelling in fluid mechanics and/or heat transfer. Behavioural competencies: Working in Teams: building and maintaining constructive and effective work relationships. Communicating Effectively: demonstrating a pro-active approach to resolving differences; addressing issues of conflict constructively. Managing Self: demonstrating a receptive approach to feedback; being open to criticism and reconsidering position accordingly. Solving Problems: seeking and integrating other points of view when tackling an issue; consulting experts in the field and undertaking benchmarking. Language skills: Spoken and written English, with a commitment to learn French.
