Contract Director, Developability and Early CMC Development (1-Year contract, full-time, onsite)
Contract (12 months, with potential to convert to FTE). Start Date: Immediately.
Location: PineTree Therapeutics, Cambridge, MA.
About PineTree Therapeutics: PineTree Therapeutics is an innovative biotech company pioneering multispecific degrader antibodies to revolutionize cancer treatment. Our proprietary platform is designed to target and degrade membrane-bound and extracellular proteins, offering a new approach to overcoming drug resistance in oncology. We are advancing a robust preclinical pipeline and actively preparing for translational and early clinical development.
Position Overview We are seeking an experienced and motivated Director of Developability and Early CMC Development to provide scientific and strategic leadership in early CMC development. The role will oversee the development of late-stage drug candidates with analytical and developability screening and cell line development. Working on‑site, the right candidate will play a critical role in ensuring efficient candidate selection and optimizing therapeutic candidates for manufacturability, scalability, and regulatory compliance.
Supervisory Responsibilities
Supervise and mentor direct reports.
Manage interactions within cross‑functional teams.
Key Responsibilities
Establish fit‑for‑purpose analytical/purification methods to support multivalent therapeutic antibodies, ADC or protein/antibody fusion lead screening and further development using proprietary in‑house technologies and external CRO/partner capabilities.
Execute purification and analytical utilizing modern equipment to support the programs at early discovery or late‑stage development including UPLC‑MS, LC‑MS, RP‑HPLC, HIC‑HPLC, CEX‑HPLC and various affinity chromatography methods.
Provide strategic input into candidate selection based on robust developability assessment outcomes, balancing scientific rigor with resource efficiency.
Collaborate cross‑functionally with Discovery, Molecular Biology, and Translational Research teams to ensure seamless transition from research to clinical development.
Lead and oversee the early‑stage CMC development strategy and execution for monoclonal and multivalent antibody candidates to the IND submission.
Design, implement, and manage comprehensive developability and pre‑formulation screening, evaluating parameters such as cell productivity, aggregation, glycosylation patterns, post‑translational modifications, solubility, stability.
Establish and optimize workflows, ensuring alignment of internal processes with industry best practices.
Manage relations with external CDMOs for CMC activities including process transfers, problem resolution, timeline management, and budget oversight.
Author key sections of IND applications related to CMC.
Communicate effectively with senior management and external partners regarding CMC strategies, progress, and risk management.
Foster a culture of innovation, teamwork, and continuous performance improvement.
Qualifications
PhD or advanced degree in Biochemistry, Chemistry, Biotechnology, (bio)chemical Engineering, or a related scientific discipline.
10+ years of experience in advancing biological molecules from late research to CMC development, specifically focused on monoclonal and multi‑specific antibody therapeutics.
Demonstrated hands‑on expertise in designing, optimizing, and validating analytical and purification techniques to support the screening and development of multivalent therapeutic antibodies.
Proven track record in Analytical Method Development and Optimization for physicochemical characterization of biological molecules.
Working knowledge of pre‑formulation activities such as excipient screening, solubility, and stability testing.
Good to have experience in protein/antibody biophysiological characterization such as CE‑SDS, cIEF, DSC, etc.
Good to have experience with stable cell line generation concepts/technology and regulatory requirements.
Good to have experience of successfully managing CRO/CDMO relationships to deliver manufacturing stable cell lines.
Good to have experience working in both large pharmaceutical companies and smaller biotech organizations, demonstrating adaptability and efficient resource management.
Required Skills/Abilities
Strong interpersonal and communication skills, with the ability to clearly articulate strategies and scientific rationale to diverse stakeholders.
Managerial or supervisory experience is mandatory.
Excellent organizational, analytical, and problem‑solving abilities.
Deep and hands‑on expertise in Analytical method development.
Experience with formulation screening and optimization.
Experience in IND submissions and early‑phase regulatory interactions.
Familiarity with various mammalian expression systems and technologies, especially CHO cell‑based production.
Experience with novel antibody formats such as multispecific antibodies or antibody‑drug conjugates (ADCs).
Team player and builder with excellent coaching skills.
High degree of integrity, professionalism, and dedication to exceptional quality.
Preferred Skills
Ability to establish high‑level strategies for new drug technologies and apply novel technologies to drug discovery.
Location Full‑time, on‑site position at PineTree Therapeutics, Cambridge, MA.
Contract Duration 1 Year (with potential for extension and conversion to FTE based on performance and business needs).
