Contribute to an exciting mission
What will your daily life look like?

Within our R&D division, the Downstream Process Design department focuses on designing and optimizing purification strategies for fermentation-derived products. To support our innovation and industrial development efforts, we are offering a one-year apprenticeship opportunity for an engineering student interested in developing and modeling downstream processes at laboratory and pilot scale.

As part of the Purification process team, your mission will be to contribute to the definition, testing and modelling of extraction and purification processes. The main unit operations involved can include tangential flow filtration, chromatography or crystallization.

Your main missions will include:

Designing and performing laboratory and pilot-scale experiments to evaluate different purification strategies.
Characterizing process performance (yield, purity, robustness) under various operating conditions.
Identifying and quantifying key phenomena (e.g. fouling, mass transfer limitations, crystallization kinetics)
Developing mathematical models using the gPROMS software (Siemens) to describe and simulate these unit operations.
Using modelling as a decision-support tool to guide process optimization and scale-up.
Documenting your work and presenting results to the R&D team.

What we propose:

A hands-on R&D experience in a dynamic and innovation-driven environment.
Exposure to industrial challenges in biotechnology and purification processes design.
A balanced mix of laboratory experimentation and advanced process modelling.
Mentorship and technical support from experienced process scientists and engineers.

Make a personal impact
That makes you the ideal candidate

Final-year student in engineering school or university (chemical engineering, biotechnology, process engineering, or related fields).
Strong knowledge of unit operations, particularly in separation processes, chromatography, and crystallization.
Interest in both experimental and modelling work.
Familiarity with simulation tools such as gPROMS, Aspen or Matlab is an asset.
Analytical mindset, autonomy and scientific curiosity.
Strong communication and teamwork skills.
Fluent in English.
