Join Baxiva and Help Shape the Future of Bacterial Vaccines

Baxiva is a biotechnology startup focused on developing next-generation glycoconjugate vaccines aimed at preventing infections caused by Gram-negative bacterial pathogens. Our lead vaccine candidate targets Escherichia coli, a leading cause of urinary tract infections worldwide and a significant contributor to antimicrobial resistance. Situated in Schlieren and on the ETH Zurich Hönggerberg campus, Baxiva offers a unique opportunity to contribute to high-impact science with real-world clinical potential.

Your Role

We are seeking a highly skilled and motivated Scientist / Analytical Chemist to develop the analytical backbone of our glycoconjugate vaccine program. You will lead the design and development of assays that define the composition, structure, and purity of vaccine components and conjugates. This hands-on and independent role requires close collaboration within the R&D team and with external partners.

Your main responsibilities will include:

• Developing and executing analytical assays for vaccine components.
• Applying and integrating techniques such as HPLC and mass spectrometry.
• Establishing reference standards and conducting phase-appropriate method qualification; writing SOPs and reports.
• Collaborating with internal teams (vaccine development and carrier protein) and building relationships with external partners for key analytical methods.
• Contributing to early CMC documentation as the program advances.

Your Profile

We’re looking for someone who takes initiative, delivers high-quality results, and enjoys tackling complex problems in a collaborative environment to create real-world impact.

You bring:

• A PhD in Analytical Chemistry, Biochemistry, Chemical/Biological Engineering, or a related field.
• Demonstrated hands-on experience developing and executing analytical methods for complex biological molecules or assemblies. Experience with glycan/polysaccharide analysis is a strong plus.
• Familiarity with analytical methods (e.g., HPLC, MS, NMR) and a comfort in developing new techniques.
• Strong documentation and organizational skills, with the ability to work independently and partner effectively with internal and external collaborators.
• Advantageous: experience with bacteriophage-derived VLPs and/or an understanding of phase-appropriate CMC requirements.
• Excellent communication skills and proficiency in English.

We Offer

We're a small, agile team of motivated scientists working in a friendly, collaborative environment where everyone contributes their unique experiences and expertise. We believe that science thrives in an atmosphere of open exchange, trust, and collaboration. We are committed to supporting the personal and professional growth of each team member.
