Parasites and pests always end up resisting the treatments that fight them. Finding the next generation requires knowing early, and with certainty, which molecule acts and by which mechanism. This is our job: we design and carry out the biological assays that allow our partners, in animal health, crop protection, the pharmaceutical industry, and in academia, to decide which substances deserve to go further.

At Invenesis, this question arises at all scales: from the isolated receptor, expressed in a Xenopus oocyte, to the whole organism. We are a dozen people in St-Blaise. A small team, where everyone's contribution truly weighs on the result.

Your mission

You will join the Electrophysiology and Molecular Biology team, where you will spend most of your time:

• preparing, selecting, and micro-injecting Xenopus laevis oocytes;
• performing electrophysiological measurements (TEVC, HiClamp) on membrane receptors (for example: nAChR, GABA-A, voltage-gated sodium channels);
• conducting molecular biology activities: cloning, plasmid preparation, in vitro transcription;
• preparing solutions and documenting each experiment with rigor.

Because we are a small team, you will also provide support for phenotypic screening and compound logistics, in BSL2: receiving, weighing, and dissolving compounds to be tested, plate preparation, maintaining parasite and arthropod cultures, participating in assays. This part varies from week to week, filling the lulls in the electrophysiology platform by absorbing the peaks of screening and vice versa.

Our parasite colonies do not stop on Friday evening; the position includes an on-call service and some weekend or public holiday interventions, organized in advance and distributed within the team.

What we are looking for

• a CFC as a biology laboratory technician, or training deemed equivalent;
• rigor and precision: our results must be reproducible;
• dexterity and patience; the ability and desire to work with living organisms: oocytes, parasites, arthropods;
• versatility, and the flexibility to switch from one activity to another according to priorities;
• ease of working in a team;
• french, and a level of english sufficient to read a protocol or a technical data sheet;
• availability to provide the on-call service and weekend interventions related to the cultures.

Electrophysiology is not required: we train in-house, and it is one of the attractions of the position. Experience in molecular biology is strongly desired, while working in a regulated environment (GLP) is a plus.

What we offer

• a position that touches the entire experimental chain, from plasmid to parasite;
• complete training in electrophysiology and working in BSL2 confinement;
• a team of about a dozen people, where what you do is seen and counts;
• recent and well-equipped laboratories;
• St-Blaise, ten minutes from Neuchâtel, by the lake.
