Job description

Cabaletta Bio (Nasdaq: CABA) is a clinical‑stage biotechnology company focused on developing and launching the first curative targeted cell therapies designed specifically for patients with autoimmune diseases. The CABA™ platform encompasses two complementary strategies which aim to advance the discovery and development of engineered T cell therapies with the potential to become deep and durable, perhaps curative, treatments for a broad range of autoimmune diseases.

The lead CARTA (Chimeric Antigen Receptor T cells for Autoimmunity) strategy is prioritizing the development of rese‑cel, a 4‑1BB‑containing fully human CD19‑CAR T cell investigational therapy. Rese‑cel is currently being evaluated in the RESET™ (REstoring SElf‑Tolerance) clinical development program spanning multiple therapeutic areas, including rheumatology, neurology and dermatology. Cabaletta Bio’s headquarters and labs are located in Philadelphia, PA.

This role can be remote or based out of our Philadelphia, PA headquarters.

Director, Clinical Scientist

The Director, Clinical Scientist plays a key role in supporting the clinical development of the company’s CAR‑T cell therapy programs in autoimmune diseases. The individual contributes to the scientific and clinical integrity of trials from early proof‑of‑concept through late‑stage pivotal studies, working closely with Clinical Operations, Translational Medicine, Regulatory, and Biostatistics to help ensure high‑quality data and alignment toward a successful BLA submission. They serve as an important scientific link between discovery and clinical execution, bringing expertise in autoimmune diseases, cell therapy, and clinical trial design to support the advancement of transformative therapies for patients.

Key Responsibilities

• Serve as a key clinical science contributor for assigned CAR‑T programs, partnering with the Medical Director and other Clinical Development team members to support study design, execution, and interpretation across all phases of clinical development.
• Lead or contribute to the preparation of key clinical documents — including protocols, amendments, informed consent forms, investigator brochures, clinical study reports, and regulatory submissions (e.g., INDs, CTAs, DSURs, BLAs/MAAs).
• Review, analyze, and interpret emerging clinical data (safety, efficacy, PK/PD) to identify trends and issues, ensuring timely resolution through cross‑functional collaboration.
• Conduct literature and competitive landscape reviews to inform study design, data interpretation, and program strategy.
• Provide ongoing data review to ensure study conduct aligns with protocol, patient safety standards, and data integrity expectations.
• Collaborate with the Medical Monitor to ensure awareness of key safety and efficacy findings, supporting SAE review, narrative development, and safety governance activities.
• Lead or support governance activities, including preparation and presentation of materials for Development, Executive, and Scientific Steering Committees, as well as oversight of external boards (e.g., DSMB, adjudication committees).
• Contribute to and present scientific and clinical data internally and externally (e.g., investigator meetings, scientific conferences, regulatory interactions).
• Serve as the clinical science representative on cross‑functional development and study teams, providing scientific and strategic input to ensure cohesive execution.
• Mentor study team members and contribute to vendor oversight to ensure consistency, quality, and scientific rigor across all clinical deliverables.
• Maintain awareness of emerging scientific and regulatory trends in cell and gene therapy and autoimmune diseases to integrate innovations into development strategy.
• Other related duties, as assigned.

Qualifications

• Advanced degree (MS, Ph.D., Pharm.D., M.D., or equivalent) in a relevant scientific discipline.
• 4‑5+ years of clinical development experience within biotech, pharmaceutical, or academic settings, with demonstrated leadership in advancing programs through early and late‑stage development.
• Cell and gene therapy experience—particularly in CAR‑T or T‑cell–based modalities—strongly preferred; autoimmune disease experience highly desirable.
• Deep understanding of T‑cell biology, immunology, and translational science principles relevant to cellular therapy.
• Proven ability to author and critically review clinical protocols, study reports, and regulatory documents, ensuring scientific integrity and compliance with ICH‑GCP and global regulatory standards.
• Demonstrated skill in analyzing complex clinical data, conducting literature reviews, and synthesizing insights to inform program strategy.
• Exceptional scientific judgment, attention to detail, and analytical rigor.
