THE COMPANY

Septerna is a biotechnology company with a vision to become the industry-leading G protein-coupled receptor (GPCR)-focused R&D company with a portfolio of life-changing medicines. The company’s Native Complex™ Platform recapitulates GPCRs with their native structure, function, and dynamics outside of the cellular environment to enable new technologies for industrial-scale drug discovery for the entire GPCR target class for the first time. Septerna has an emerging pipeline of GPCR-targeted small molecule drug discovery programs, along with growth potential to reach many GPCRs that have been undruggable and unexploited to date. Septerna was launched by scientific founders who have made groundbreaking GPCR discoveries and by founding investor Third Rock Ventures. For more information see: www.septerna.com.

·       Stay informed with the latest advancements in protein expression and purification technologies, particularly in the context of GPCRs, and actively contribute to structural biology efforts

·       Work in a collaborative environment to support discovery and structural biology efforts for internal drug discovery programs

·       Effectively analyze and interpret data, as well as communicate updates to management and cross-functional teams

·       Maintain accurate laboratory documentation, reports, and protocols, and present scientific data to colleagues in group and project team meetings

QUALIFICATIONS

·       PhD in Structural Biology, Biochemistry, Biophysics, or other related disciplines is required, with work experience in optimizing protein purification protocols, protein characterization methods, and protein structure determination using cryoEM

·       Strong core competency in protein biochemistry, protein purification, and structural biology are essential, with demonstrated success in developing and optimizing protein purification protocols for cryoEM studies

·       Minimum of 4+ years of research experience, 0-2 years of related experience post-PhD

·       Experience in cryoEM data collection, data processing, and model building and working knowledge of associated software tools such as CryoSPARC, Chimera, Phenix, Coot, or similar

·       Proven expertise in protein purification techniques, with working knowledge of FPLC platforms (AKTA, Bio-Rad).

·       Proficiency in aseptic cell culture techniques and recombinant protein expression in bacterial, insect, and mammalian systems is required.

·       Familiar with biochemical and biophysical techniques used for protein characterization, such as luminescence, fluorescence, and FRET-based methods.

·       Experience with prokaryotic and eukaryotic expression vectors and construct design for structural biology studies.

·       Proficient at sustained communication with superiors and working in a highly collaborative, cross-functional team environment

·       Strong work ethic with an ability to multi-task and independently plan experiments, analyze and interpret data, troubleshoot challenges and come up with solutions.

·       Attention to detail, accurate record keeping, and strong oral and written communication skills 

Preferred Qualifications: 

·       Prior experience with protein purification and protein characterization of membrane-spanning proteins such as GPCRs, is a bonus.

·       Proven experience with protein purification, stabilization, and characterization of difficult protein targets.

·       Willingness to work outside of their discipline to accomplish project goals.

·       Experience with automation and data analysis/reporting software is highly desired.
