4 Scientist Openings at MoleSense

• Aptamer Scientist
• Analytical Chemist
• Microfluidics Scientist
• Photochemist

Sweat is more than water — it’s a molecular window into human health. At MoleSense (EPFL Neuchâtel or Biopôle Lausanne), we’re developing the next generation of epidermal microfluidic biosensors that decode sweat and interstitial fluid chemistry in real-time. We’re a small, fearless team of scientists and engineers, blending rigor with imagination to transform women’s healthcare — starting with non-invasive monitoring of pregnancies.

Who You Are

If you thrive at the intersection of biology, nanotechnology, and electrochemistry and identify with one (or several) of the following profiles, we want to meet you.

• Aptamer Scientist: Expertise in nucleic acid chemistry, aptamer engineering, and bioconjugation, with demonstrated experience in SELEX, aptamer selection, structural modification, and nucleic acid folding dynamics. Extensive experience in electrochemical aptamer-based biosensors, DNA nanotechnology, and functional nucleic acid architectures is highly desirable.
• Analytical Chemist: Strong background in electrochemical biosensing, including techniques such as impedance spectroscopy, cyclic and square-wave voltammetry, and redox-based signal transduction. Expertise in interface chemistry and surface passivation, with a proven track record in developing multiplexed and regenerable sensor platforms.
• Microfluidics Scientist: Experienced in developing acoustofluidic, optofluidic, epidermal/wearable microfluidics/lab-on-chip, or organ-on-chip platforms. Solid theoretical knowledge of fluid mechanics and interfacial physics, with strong experience in epidermal microfluidics for ultra-low-volume sweat sampling.
• Photochemist: Specialized in synthetic photochemistry, interface phenomena, and light‐controlled molecular systems, with capabilities in modeling photo-responsive behavior using computational or theoretical approaches to guide experimental design.

Bonus Skills

• Understanding of sweat gland physiology or interstitial fluid transport.
• Knowledge of biocompatibility, flexible device mechanics, and regulatory standards.
• Experience in human testing or clinical collaborations.
• Development of wearable sweat biosensing systems from concept to completion during your PhD or postdoc is a significant plus.
• Possession of Swiss/EU/EFTA citizenship or a lucrative B permit in Switzerland.

General Qualifications

• Creative, curious, and tireless.
• An experimentalist at heart, passionate about building, testing, iterating, and solving complex technical challenges across disciplines.
• High levels of initiative, integrity, and scientific curiosity, demonstrating ownership and excellence in every project.
• A genuine desire to make science matter intellectually, technologically, and societally.
• A proven record of independent, high-impact research, evidenced by peer-reviewed publications and/or competitive postdoctoral fellowships.

What We Offer

• An English-speaking, international work environment at the intersection of academia and deep tech innovation.
• Work permit sponsorship in Switzerland for eligible international candidates.
• The opportunity to make a socially meaningful scientific contribution, developing technology that advances real-world healthcare impact.
• State-of-the-art lab and office space at the Biopôle campus in Lausanne, with panoramic views of Lake Léman and access to cutting-edge EPFL research platforms.
• A dynamic, merit-based, and collaborative culture that values creativity, rigor, and open scientific exchange.
• The chance to mentor and lead a small team of talented interns or master’s students, with opportunities for leadership as the project scales.
• Be part of a vibrant, curiosity-driven team that thrives on shared energy, late-night experiments, and the excitement of discovery.
• A pathway to becoming a key early team member in a rapidly growing research-driven startup.
• Extendable 1-year contract (with a 3-month probation period).
• Competitive salary and excellent working conditions, exceeding Swiss academic standards.
