Septerna is a biotechnology company based in South San Francisco, CA on a mission to develop life-changing medicines for patients with the vision to become the industry-leading G protein-coupled receptor (GPCR)-focused drug discovery company. The company’s Native Complex Platform™ recapitulates GPCRs with their native structure, function, and dynamics outside of the cellular context. This approach enables novel access to modern structural and screening technologies used in industrial-scale drug discovery for the entire class of GPCRs. Septerna has an emerging pipeline of GPCR-targeted small molecule programs with potential for growth to target many GPCRs that have been undruggable and unexploited to date.

We are excited to expand our multidisciplinary team of individuals focused on creating revolutionary medicines to address the unmet needs of patients. At Septerna we strive to embrace diversity of thought, expertise, and background through collaboration. To join our ambitious team, be prepared to bring your real self to work every day; grow and learn from a talented team of drug hunters, scientists, and business professionals; and contribute your passion, creativity, and energy to accomplish our mission. We share a fearless pursuit of ground-breaking innovations and cultivate an environment where our employees succeed by learning from each other and working as a team.

We are committed to the development of meaningful therapeutics for patients with indications of high unmet need. This is a tremendous opportunity to work with talented individuals on the frontlines of therapeutic discovery and development. You will directly help move therapies through preclinical research, positioning them for success in the clinic. The successful candidate will add their passion, unique talents, and expertise to a dynamic team motivated to discover new disease-modifying therapeutics for patients in a fast-paced environment.

  • Assist in the development and execution of platforms for parallel screening of protein production constructs to enable optimization of protein quality and yield.
  • Responsibilities will include eukaryotic cell culture, automated column chromatography (FPLC/HPLC), microscale protein purification, and protein QC.
  • Work in a collaborative environment to support discovery, biophysics, and structural biology efforts for internal drug discovery programs.   
  • Data analysis, documentation, and presentation in group and project team meetings 

Qualifications

  • BS with 10 years or MS with 7 years of relevant experience in a biotechnology or pharmaceutical setting.
  • Experience in hands-on large-scale recombinant protein purification using FPLC-based column chromatography including affinity, ion exchange, hydrophobic interaction, and size exclusion on a variety of proteins and protein families.
  • Experience purifying proteins from bacterial and eukaryotic expression systems is essential. Mammalian cell culture experience, particularly with HEK293-based systems, is highly desirable.
  • Experience with purification and characterization of membrane proteins, particularly GPCRs, using detergents, nanodiscs, amphipols, and other stabilization technologies is considered a plus.
  • Use of multi-parallel purification technologies (magnetic beads, PhyTips, etc.) and automated protein production screening would be desirable.
  • Familiarity with protein characterization techniques including multi-angle light scattering (MALS), Differential Scanning Fluorimetry (DSF), analytical size exclusion (AnSEC), etc.    
  • Demonstrated experience working collaboratively in a team-oriented environment while also working independently on experimental planning, data analysis and interpretation
  • Clear and effective verbal and written communication skills
