Scientist, Antibody Discovery

Company Description Stipple Bio, Inc. is a private biotechnology company harnessing epitope-level precision to create targeted cancer therapies. We pioneered a Pointillist epitomics' discovery platform to unlock tumor-specic epitopes and develop a pipeline of next-generation precision oncology therapeutics with a high therapeutic index. Our lead candidate STP-100, designed to avoid on-target/off-tumor toxicity, is expected to enter clinical studies in early 2027. Stipple Bio is well capitalized and has announced a $100M Series A nancing which supports the company into 2029. Role Description The Scientist II, Antibody Discovery role at Stipple Bio is a PhD level scientist position within the Research department, reporting to the Director, Target & Antibody Discovery. This role is pivotal in advancing the company's mission to develop cancer therapies through innovative cellular proling and epitope-level target and antibody discovery. Based in Cambridge, Massachusetts, the position involves overseeing the antibody engineering efforts by integrating structural insights with biochemical and cellular characterization, collaborating across teams, and advancing antibody therapeutic candidates from discovery through preclinical development. It requires a blend of scientic expertise, critical thinking, and operational management to bridge antibody discovery and development candidate nomination in a dynamic biotech environment. This is a full-time, on-site position. Job Duties Lead structure-guided antibody and protein engineering efforts Play a critical role in the design and discovery of antibody therapeutics across multiple modalities, including T Cell Engager (TCE), Antibody Drug Conjugate (ADC), Bi- or Multi-specic Antibodies Design and execute functional and mechanistic characterization of therapeutic antibody candidates Collaborate seamlessly with Platform Technology, Antibody Discovery, Computational biology and Translational Biology teams to drive antibody characterization and engineering activities and advance discovery programs Develop and expand internal antibody discovery and engineering capabilities (e.g., affinity maturation) Contribute to drug target evaluation/prioritization and product concept development Analyze, interpret, and effectively communicate experimental data to the team; maintain data integrity, and detailed documentation Conduct and oversee research activities with external research organizations (CROs) as needed
