• Manage oligonucleotide sample analysis, collaborating closely with R&D teams to interpret multi-technique results.

• Take part in routine and high-throughput analyses, supporting projects across the company.

• Drive method transfer to QC and ensure robustness for future scale-up.

• Own instrument performance: maintenance, qualification, SOPs, logbooks, and system suitability testing.

• Author high-quality protocols and technical reports, and contribute to scientific reviews and continuous learning.

• Promote cross-team collaboration and act as an analytical science ambassador within the organization.

🧬 What We’re Looking For

Must-Haves:

• MSc or equivalent in Analytical Chemistry, Biochemistry, or related field.

• 5+ years’ experience in analytical development using LC/MS (low and high resolution) on biomolecules.

• Deep expertise in UHPLC and mass spectrometry data analysis, including software tools.

• Strong interpersonal and communication skills – French and English proficiency required.

• Self-motivated and team-oriented with a hands-on, proactive mindset.

Nice-to-Haves:

• PhD in Analytical Chemistry

• Industry experience (biotech, pharma, start-up environments)

• Familiarity with automation, SPE, and liquid handling robotics

🌱 Why Join Us?

• Work with top-tier scientists in a high-growth, mission-driven biotech company

• Collaborate in a supportive and intellectually curious team

• Be a key player in setting standards and innovating analytical methods

• Access to the latest technologies in analytical instrumentation

• Competitive compensation and a dynamic work culture
