Job description

Senior Scientist / Principal Scientist, Biotherapeutic Engineering

Xilio Therapeutics is a clinical-stage biotechnology company discovering and developing tumor-activated immuno-oncology (I-O) therapies with the goal of significantly improving outcomes for people living with cancer without the systemic side effects of current I-O treatments. The company is using its proprietary platform to advance a pipeline of novel, tumor-activated clinical and preclinical I-O molecules that are designed to optimize their therapeutic index by localizing anti-tumor activity within the tumor microenvironment. Learn more by visiting www.xiliotx.com and follow us on LinkedIn (Xilio Therapeutics, Inc).

SUMMARY:

Xilio Therapeutics is seeking an experienced and initiative-taking individual to help build internal discovery capabilities using display technologies. This hands-on position involves generation and screening of antibodies, proteins, and peptides to be used in the company's conditional scaffolds for the development of novel tumor activated therapeutics. This is a high-impact position with the potential to shape the future trajectory of the company. The ideal candidate will have hands-on experience in display technologies such as phage and/or mammalian/yeast, and necessary molecular biology techniques.

Job Responsibilities:

• Build strategies for selection and screening of mAbs, protein domains and peptides using display from synthetic libraries (i.e., Phage display).
• Design and optimize strategies to lift immune repertoires from immunized animals to create immune libraries, manage and manipulate these libraries to isolate mAbs, sdAbs with large diversity.
• Generate libraries for display platforms for therapeutic optimizations such as affinity maturation, potency, and stability enhancements of antibodies, proteins, and peptides.
• Conduct in vitro discovery campaigns using phage display (added bonus yeast/mammalian display also).
• Conduct/lead campaigns utilizing display, and single B-cell platforms towards mAb and peptide discovery.
• Design and execute strategies to amplify and clone antibody variable regions, protein domains or peptides from display libraries into final therapeutic format.
• Able to manage CROs and build workplans for synthetic library generation and/or animal immunizations.
• Lead/co-lead core discovery teams.
• Represent Protein Engineering function at project team and group meetings.
• Maintain laboratory stocks and reagents and serve as a mentor to junior staff.
• Keeps a detailed and well-organized electronic laboratory notebook.
• Stays current with literature and emerging trends in the discipline.

Skills, Qualifications, and Requirements:

• PhD in Molecular Biology, Biochemistry, Microbiology, Structural Biology, or related field.
• BA + 7-10 years or MS + 4-7 years of experience in an antibody discovery team in the pharmaceutical or biotechnology industry.
• Firsthand experience in mAb discovery platforms such as display, and/or single B-cell is required.
• Phage display experience required. Yeast/mammalian (including FACS analysis and sorting) desired.
• Experience with prokaryotic or eukaryotic display technologies.
• Expertise in molecular biology techniques (PCR, cloning, primer design, plasmid preparation, etc.) is required.
• Handling and manipulation of cell cultures is required.
• Working knowledge of high-throughput plate-based processes is desirable.
• Experience with plate-based expression in bacterial and/or yeast/mammalian cultures is desirable.
• DNA sequence analysis/editing is desirable.
• Familiarity with formatting scFvs and VHH/nanobodies/sdAbs is desirable.
• Ability to work independently in a dynamic environment. Ability to work on multiple projects in parallel to deliver results in rapid timeframes.
• Critical thinking, prioritization of tasks, attention to detail and troubleshooting.
• Creativity in approaches to complex problems and desire to expand technical skill set.
• Timely delivery of team goals and ability to build productive relationships with colleagues across a research organization.
• Experience leading discovery/research project teams a plus.
