## About the Role

We are seeking a motivated Research Associate II to join our Integrated Therapeutic Engineering and Design (ITED) team and help advance the discovery and development of innovative protein therapeutics. In this hands-on role, you will play a key part in discovering novel therapeutics through yeast display-based protein engineering. You will perform all techniques associated with yeast display, including culture and induction of yeast, transformation of yeast with DNA-based libraries, and phenotypic selection using fluorescence activated cell sorting (FACS) or magnetic activated cell sorting (MACS). The ideal candidate is proficient with advanced molecular biology techniques, such as PCR, primer design, golden gate cloning, and DNA preparation for sequencing, and brings bench experience with protein display technologies, preferably yeast display. You will own experimental design, implementation, and data analysis, and share your results with your supervisor and the broader team in an
effective and timely manner. Drive to execute, experimental rigor, and scientific curiosity are essential to success in this role. Strong interpersonal, verbal, and written communication skills will enable you to thrive within our highly collaborative, cross-functional teams., * B.S. or M.S. in Biochemistry, Biology, Bioengineering, Immunology, or a similar field.

 * 2+ years of academic or biotech/pharma laboratory experience.
 * Experience with protein display technologies is required. Yeast display experience is strongly preferred.
 * Demonstrated understanding of complex molecular biology techniques is strongly preferred (e.g., PCR, primer design, DNA purification, DNA library design and construction using multiple methods (golden gate cloning, Gibson assembly, SOE), maintenance and culture of yeast and E. Coli).
 * Strong organizational skills, excellent attention to detail, and data analysis skills are required.
 * Knowledge of oncology or immunology is beneficial.
 * Experience with FlowJo, SnapGene, and JMP preferred.
 * Desire and ability to quickly learn new lab techniques and understand the significance to program goals.

## Description

* Design and execute experiments as a key contributor to the ITED team, under the supervision of your manager and scientific project leads.
 * Apply recombinant protein display systems (e.g., yeast display) to protein engineering applications.
 * Design and construct DNA libraries using molecular biology techniques (e.g., DNA isolation and purification, PCR, and transformation of yeast and/or E. coli).
 * Enrich displayed libraries for phenotypes of interest using FACS and MACS, and analyze target binding profiles.
 * Maintain good laboratory practices, including accurate ELN documentation, instrument and reagent validation, and adherence to lab safety policies.
 * Present data and analysis at cross-disciplinary team meetings and build working relationships that move projects forward.
