Bioengineer, Molecular Biology

About the role

Adaptyv is building an automated lab that lets AI agents run biology experiments, and is hiring a hands-on research Bioengineer for its biology and production team in Lausanne. The role covers developing and optimizing protein expression systems, running molecular biology workflows and characterizing products at scale. It is not a project management role: you will be at the bench doing molecular biology, analyzing data and iterating on protocols.

Key responsibilities

• Develop and optimize protein expression workflows (cell-free PURE and lysate-based, E. coli, and possibly mammalian systems) and troubleshoot non-expressing, misfolded or aggregated proteins.
• Design and run DNA synthesis and assembly protocols (PCR, Golden Gate, Gibson) and improve yield, fidelity and throughput.
• Develop new assays or adapt existing ones for the platform (thermostability, developability, enzyme activity).
• Run experiments yourself, analyze data, identify failure modes and improve methods systematically.
• Work with the automation team to turn your methods into automated workflows.

Required profile

• MSc or PhD in molecular biology, bioengineering or a related field; hands-on bench experience counts more than the degree title.
• Rigorous experimentalist who keeps detailed notes, designs proper controls and understands reproducibility.
• Comfortable interpreting chromatograms, binding curves and expression gels.
• Interested in automation, even if you do not program robots.
• Independent and resourceful, troubleshooting with literature and first principles.

Required skills

• Practical protein expression and purification skills.
• Experience with DNA synthesis, cloning or assembly (PCR, Golden Gate, Gibson); high-throughput experience is a plus.

The position is full time, on site in Lausanne, with an ASAP start date. Applications are reviewed on a rolling basis.
