Director/Head of CMC

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.

Position Overview TwoStep Therapeutics is seeking a hands-on Director/Head of CMC to lead execution of our Chemistry, Manufacturing, and Controls (CMC) strategy across a growing therapeutic portfolio. This role will be responsible for translating early development programs into robust, scalable, and regulatory-ready processes capable of supporting clinical development. The ideal candidate is an experienced CMC leader who thrives in a fast-paced biotech environment, takes full ownership of deliverables, and has a strong track record of advancing peptide, small molecule, and radiopharmaceutical programs through early clinical development within an outsourced manufacturing model. While this role is envisioned as a full-time position, we are open to part-time, or hourly consulting arrangements for highly qualified candidates - particularly those with deep expertise in CMC development of radioligand assets.

Key Responsibilities

• Own and execute phase-appropriate CMC development plans from discovery handoff through clinical development
• Lead all drug substance (DS) and drug product (DP) activities, including process development and optimization, cGMP manufacturing, analytical development (including method validation and stability programs), and formulation development (fill/finish, lyophilization optimization, etc.)
• Oversee CMC execution for radioligand programs, including management of radioisotope suppliers, radiochemistry development partners, and clinical radio-CMC operations
• Drive selection, contracting, and management of CDMOs to ensure high-quality and on-time phase-appropriate batch delivery to external vendors/clinical sites
• Manage timelines and budgets, monitor performance metrics, and proactively mitigate technical and supply chain risks
• Ensure compliance with cGMP, ICH guidelines, and global regulatory standards across all CMC activities
• Lead preparation, authoring, and review of CMC sections for regulatory submissions (INDs, IMPDs, NDAs, and future BLAs/MAAs). Serve as CMC technical lead in regulatory interactions with FDA, EMA, and other health authorities
• Serve as the CMC subject matter expert on cross-functional program discussions across Research, Nonclinical Development, Clinical Development, and Quality Assurance

Essential Qualifications

• Advanced degree in a relevant field (Chemical Engineering, Biomedical Engineering, Biochemistry, Pharmaceutical Sciences, etc.) or equivalent experience in CMC development
• A minimum of 5 years of progressive experience in the biopharmaceutical industry, with extensive experience in the CMC development of peptides and/or small molecules from early process development to the clinic
• Demonstrated expertise in radiopharmaceutical CMC development (radiolabeling, analytical methods, formulation considerations, and supply logistics)
• Proven experience operating within a fully outsourced manufacturing model, including CDMO selection, contracting, oversight, and performance management.
• Deep working knowledge of cGMP requirements, ICH guidelines, and global regulatory expectations, with hands-on experience authoring and reviewing CMC modules for regulatory submissions
• Strong project management skills with the ability to balance technical depth and program timelines
• Comfortable operating in a lean, high-growth biotech environment where adaptability and accountability are essential

Preferred Qualifications

• Experience with radiopharmaceutical site selection, method transfer, and evaluating clinical site readiness
• CMC experience with peptide-drug conjugates
• Experience supporting late-stage clinical development or commercial readiness activities
