Job description

About LIOM

LIOM is a Swiss deep-tech company building the ultimate health wearable for conscious living – a continuous, needle‑free window into your body's chemistry, starting with glucose. Through this, we empower users to make informed lifestyle choices and live healthier and longer lives. Developed in Switzerland over 8+ years by 50+ scientists, validated across 130+ subjects, and protected by 23 patent families.

Your mission

As a Principal/Senior ML Scientist, you will research and collaboratively build computational solutions to real‑world problems in our domain: a continuous non-invasive multi‑biomarker monitoring smartwatch. Your work involves acquiring and smartly combining deep multi‑disciplinary knowledge (biophotonics, biomedical, microfluidics, electronics, and manufacturing).

Your profile

• Master's / PhD degree in Computer Science, Informatics, Statistics, Applied Mathematics, Electrical Engineering, Operations Research, Biomedical Engineering, related technical field, or equivalent algorithm development experience.
• Demonstrable capacity to digest scientific literature effectively, including cross‑disciplinary domains.
• High attention to detail and proven ability to manage multiple, competing priorities, being comfortable in a dynamic and sometimes ambiguous environment.
• 5+ years of experience in writing computational software working with at least one compiled and one interpreted language such as Python, Julia, Java, or C++
• 3+ years of experience in ML frameworks (e.g. Pytorch, Tensorflow, Jax), custom model development, and stochastic optimization
• 3+ years of experience in industry or applied environment
• Thorough understanding of the linear algebra, probability theory, and calculus underlying machine learning methodology
• The following qualifications are a plus:
  • Experience with transformer architectures, self‑supervised learning, and foundation models
  • Experience with training and optimizing machine learning models for time series data (e.g. health signals, audio, video)
  • Experience in analyzing -omics data
  • Experience in optics or photonics

IMPORTANT: We cannot sponsor work permits for non‑EU / EFTA nationals for this role. Applications that do not fulfill this criteria will be automatically rejected.
