## Description

### **The role**

We are building an automated biology platform and, and we are looking for a molecular biologist / research scientist to handle the core wet lab work: selection design, library construction, and readouts.

### **Responsibilities**

- Run end to end workflows, library through selection to characterized hits

- Design selection strategy: stringency schedules, bottlenecks, counter-selections

- Design FACS sorting and screening strategies, and interpret population trajectories across rounds

### **Must-haves**

- Cell culture: hands-on experience, ideally with yeast.

- Molecular cloning: fundamentals (PCR amplification, Gibson assembly, Golden Gate assembly, transformations); experience with sequencing services.

- Flow cytometry/FACS: gating strategies, staining, sample loading.

### **Nice-to-haves**

Yeast genetics and surface display · OrthoRep or other continuous hypermutation systems · phage display or PACE · SPR/BLI · NGS library prep and analysis · protein expression and purification · Opentrons, Hamilton, Tecan, or eVOLVER-class hardware.
If you have never worked in yeast, apply anyway. We would rather hire for selection judgment and long-run discipline, and teach the organism.
