Job Description

Company Overview

TwoStep Therapeutics is a biotechnology company developing a pipeline built around a unique tumor-targeting polyspecific integrin-binding peptide (PIP) that can selectively bind several targets that are highly expressed on solid tumors. This multi-targeting feature enables the agent’s broad applicability to a wide range of tumor types and patient populations, overcoming the limitations of single-antigen targeting approaches. The company has leveraged this technology to create a pipeline of targeted cancer therapies for cytotoxic drug delivery and radioligand therapy. TwoStep Therapeutics was co-founded by CEO, Caitlyn Miller, in collaboration with leading academic entrepreneurs at Stanford University, including Nobel Laureate Carolyn Bertozzi, Jennifer Cochran, and Ronald Levy.

• Prior experience in a CMO, senior VP of Clinical Development, or equivalent medical leadership role in a biotech or pharmaceutical organization, ideally in a fast-paced, innovative environment.

• Hands-on, execution-oriented mindset with a willingness to actively contribute to pipeline advancement, including protocol design, data interpretation, and cross-functional problem-solving.
