Postdoctoral Researcher in AI/ML-driven LC-MS for biopharmaceutical characterization (80%)

The Mass Spectrometry and Separation Sciences Laboratory (MS3L) at the HES-SO Valais-Wallis is seeking a highly motivated and skilled Postdoctoral Researcher with expertise in liquid chromatography high-resolution mass spectrometry (LC-HRMS), proteomics and biotherapeutic characterization. The successful candidate will combine hands-on Orbitrap-based analysis with active participation in the development of AI/ML-assisted data processing, working in a multidisciplinary team alongside software engineers and industry partners.

Key responsibilities

• Operate and maintain the LC-Orbitrap system, including method setup and routine troubleshooting.

• Develop and execute sample-preparation protocols for intact-mass and peptide-mapping analysis of monoclonal antibodies and related biopharmaceuticals.

• Perform HRMS data processing, interpretation and reporting, including multi-attribute method (MAM) and critical-quality-attribute workflows.

• Analyze host cell protein (HCP) profiles.

• Collaborate with software engineers to design, test and validate AI/ML tools for LC-HRMS data analysis and pipeline optimization.

• Engage with industry partners to translate methods into application-ready workflows.

• Contribute to manuscripts, project reports and scientific presentations.

Selection criteria

• PhD in Analytical Chemistry, Biochemistry or a related field.

• Demonstrated hands-on experience with LC-HRMS operation, in particular Orbitrap mass spectrometers.

• Experience with protein/biopharmaceutical sample preparation and LC-MS data analysis.

• Working proficiency in at least one scripting language (R, Python or similar) for data handling and analysis.

• Strong assets include: experience with antibody characterization; familiarity with MAM workflows and HCP analysis; experience applying AI/ML methods to analytical data; experience with nano/micro LC instrumentation.

• Strong organizational, communication and collaborative skills.

• Proficiency in English (spoken and written) is required; French and German language skills are a plus.

What we offer

• Stimulating applied research addressing real-world challenges in AI/ML for biopharmaceutical analysis.

• Close collaboration with expert scientists, engineers and industry partners.

• Access to state-of-the-art mass spectrometry instrumentation and computational tools.

• Excellent teaching and laboratory facilities in a modern analytical chemistry environment, with the opportunity to develop teaching and student mentoring experience.

• A position based in Sion, a picturesque town in the heart of the Alps and the sunny capital of Valais.
