Internship - Biotechnologies

About us

Spore.Bio is a deeptech start-up born in 2023, building a new paradigm in the quality control systems in Food&Beverage, Cosmetics, and Pharmaceutics factories.

After spending a lot of time in factory environments, we saw the pain it was to make sure products were safe. Traditional quality control has heavy constraints and long waiting times. To change that, we decided to build Spore.Bio , a new generation of microbiological testing.

Our team is dedicated to bringing technology and developing a cutting-edge solution, based on advanced optical and deep-learning technologies, to detect bacterial contamination within seconds.

The role

You'll run the biotechnology experiments that help us decide what goes into our detection platform. You'll work closely with our Biophysics Engineer. You'll carry out experiments at the bench, record them carefully and share your results with the team.

What you'll do

• Biotechnology development: run and optimize experiments.

• Biotechnology performance: measure detection limits, reproducibility and stability. Find sources of background and variability, and fix them.

• Documentation: keep a thorough lab notebook and present your results to the team.

• Integration: share what you learn with the biology, hardware and software teams as the assay moves toward our platform.

About you

• Final-year Master's or Engineering School student in Biotechnology, Biochemistry, Immunology, Microbiology, Bioengineering or a related field.

• Hands-on technical experience in a previous internship or lab experience: Routine ELISA or related methods, surface functionalization, bacterial sample handling, sterile technique.

• Careful record keeping: you document every experiment in your lab notebook so anyone could reproduce it.

• You work in a rigorous, organized way: well-planned experiments with proper controls.

• Reliable at the bench: you follow protocols and instructions precisely, and you ask questions when something is unclear.

• Curious and eager to learn.

• English required, French a plus.

We don't expect you to know everything on day one. Curiosity and drive matter more.

Why join

Real technologies for a real product, at the intersection of microbiology and optical detection. You'll get direct mentoring and hands-on training, and your work will feed directly into our choices for the platform. We hire for the long term: this internship can lead to a permanent position (CDI) for the right person.
