• Develop, validate, and optimise analytical methods, notably by GC, LC, GC-MS, LC-MS, and associated techniques.
• Ensure the quality, reliability, and relevance of methods and analytical results, respecting laboratory requirements and applicable standards (ISO 17025, ISO 9001, GLP).
• Contribute to the management of the analytical portfolio (Asset Management) and investments (CAPEX), according to needs and activity evolution.
• Help organise and coordinate analytical activities according to priorities, available resources, and client needs within the department.
• Participate in the evolution of the laboratory’s analytical capabilities and processes to support the objectives and strategic directions of the service and CIMO’s mission.
• Contribute to the implementation, monitoring, and continuous improvement of micropollutant and industrial sample analyses (air, water, soil), using gas or liquid chromatography and mass spectrometry (GC, LC, GC-MS, GC-MS/MS, LC-MS, LC-MS/MS).
• Help organise analyses according to priorities, workload, and available resources, in collaboration with other team members.
• Provide technical support to laboratory technicians: methodological advice, problem-solving, and daily assistance.
• Ensure and participate in the maintenance of analytical equipment and technical monitoring of instruments.
• Propose, develop, validate, and optimise analytical methods according to service needs and client expectations.
• Contribute to the management of the analytical portfolio (Asset Management) and investment projects (CAPEX), from defining needs to commissioning and equipment monitoring.
• Contribute to technical documentation and the drafting of analysis and activity reports.
• Serve as a technical reference, ensuring the quality, reliability, and compliance of methods and results with laboratory requirements and the ISO/IEC 17025 standard.
• Actively participate in managing non-conformities and internal or external quality audits.
• Engage in continuous improvement initiatives of the laboratory, both technically and organisationally.
• Minimum: Federal Certificate of Competence (CFC) as a chemistry laboratory technician (or equivalent in Switzerland or abroad)
• Advantage: HES Chemical Engineer and/or higher education in analytical chemistry, environmental chemistry, or analytical sciences.
• At least 7 years of experience in an analytical laboratory, ideally in environmental and industrial analytical chemistry.
• Proven mastery of GC, LC, GC-MS, LC-MS, GC-MS/MS, and UPLC-MS/MS techniques.
• Experience in developing, validating, and adapting analytical methods.
• Excellent knowledge of micropollutants and their analysis in air, water, and soil matrices.
• Experience in maintenance and technical monitoring of analytical equipment.
• Good knowledge of quality requirements and standards ISO 9001, ISO 17025, and GLP.
• Experience in writing procedures and participating in quality audits.
• Ability to analyse complex situations and propose appropriate technical solutions.
• Experience in providing technical support to colleagues and/or projects, without necessarily having held a managerial role.
• Proficiency with IT tools and laboratory technical software (Limpsophy); SAP is an advantage.
• Experience in investment projects for analytical equipment (CAPEX) and/or managing an instrumentation portfolio is an asset.
• Organisational skills, responsiveness, and adaptability to changing priorities.
• Ability to work independently while collaborating effectively with the team.
