A family-owned company, bioMérieux has grown to become a world leader in the field of in vitro diagnostics. For more than 60 years and across the world, we have imagined and developed innovative diagnostics solutions to improve public health. Today, our teams are spread across 46 countries and serve 160 countries with the support of a large distribution network.

Come and join a family-owned global company with a long-term vision, and a human-centered culture.

The internship will take place in Marcy-l’Étoile, near Lyon, within the Global HSE & Sustainability team. This team supports the company’s health, safety and environmental protection approach worldwide, working with regional teams and local representatives at sites and subsidiaries. Its responsibilities include occupational risk prevention, carbon footprint reduction, hazardous substance management, improvement of products’ environmental performance, and management of HSE data and indicators.

In this context, the intern will contribute to developing an internal Life Cycle Assessment (LCA) methodological framework tailored to in vitro diagnostic (IVD) products. This framework will aim to improve the comparability and reuse of LCA studies within bioMérieux. The intern will work with the LCA expert and the internal network of eco-partners, bringing together functions including R&D, procurement, packaging, supply chain and marketing. Based in France, the intern’s work will have an international scope across bioMérieux’s main product ranges.

What are your responsibilities at bioMérieux?

Development and formalization of bioMérieux’s LCA methodology

Review existing LCAs, current practices, available data and potential methodological gaps.

Conduct a literature review of applicable standards and best practices, including ISO 14040 and ISO 14044, as well as relevant sector-specific guidance.

Define and document common rules for study objectives, functional units, system boundaries, reference scenarios, allocation rules, data quality requirements, uncertainty management and interpretation principles.

Propose a harmonized approach to data collection, selection of emission factors and life cycle inventory datasets, and traceability of assumptions and sources.

Develop a practical methodological guide supported by templates, tools and review criteria for use in future studies.

Application to priority product ranges and deployment

Review existing LCAs of the main product ranges and assess their alignment with the defined methodology.

Identify missing data, limitations, sensitive assumptions and potential update needs for each product range.

Harmonize models and, where necessary, recalculate or supplement results to enable consistent interpretation across product ranges.

Perform contribution, sensitivity and uncertainty analyses to identify the main impact drivers and opportunities for environmental improvement.

Prepare a clear summary of results and recommendations for PEP, R&D, industrial and marketing teams.

Present findings to key stakeholders and support adoption of the methodology by the relevant teams.

Who are you ?

Education / background: final-year engineering or master’s student (five years of higher education), specializing in environmental science, eco-design, life cycle assessment, industrial engineering, process engineering or a related scientific field.

Experience

theoretical training in life cycle assessment is required, together with a sound understanding of its fundamental principles: goal and scope definition, functional unit, life cycle inventory, life cycle impact assessment and interpretation of results. Initial practical experience through an academic project, a thesis or professional experience would be an asset, but is not mandatory.

a strong interest in data analysis and digital tools is expected. Knowledge of LCA software (SimaPro, GaBi, etc.), Excel, environmental databases (ecoinvent), or the healthcare and in vitro diagnostics sector would be an asset and may be further developed during the internship.

Skills and languages

scientific rigor and the ability to structure, document and critically assess methodological assumptions, data quality, sources and limitations.

strong analytical and synthesis skills, with the ability to work with complex or incomplete datasets and communicate results clearly to both technical and non-technical audiences.

ability to organize work independently, manage priorities and deliver structured outputs within agreed deadlines.

ability to collaborate across functions with international contacts, collect and critically review input data, and align stakeholders around a common methodology. Professional proficiency in English and French is required.
