Job Description:

Allogene is seeking a Senior/Principal Scientist, Process Development to support the development and characterization of clinical-scale manufacturing processes for Allogene’s CART therapies.

This individual will contribute to the development, implementation and characterization of state-of-the-art processing technologies to deliver scalable and robust clinical and commercial manufacturing processes and support successful tech transfer for GMP manufacturing.

Responsibilities include, but are not limited to:

  • Actively contribute to development, implementation, characterization and successful execution of robust, state-of-the-art CART manufacturing processes.
  • Apply Quality by Design principles to develop a deep understanding of process/ product relationships to define and enable robust, integrated control strategies
  • Build and develop capabilities to enable characterization and validation of allogenic CAR T therapies including development of robust risk assessments and characterization plans developed using Design of Experiments and Quality by Design methodology to support BLA and commercialization
  • Develop and optimize cell therapy manufacturing process scale down models.
  • Support clinical-scale non-GMP/ GMP IND-enabling manufacturing operations, including Tech Transfer to CMO and support of successful GMP manufacturing of clinical material.
  • Support and contribute to relevant and impactful innovation programs to enhance CART manufacturing technologies/ capabilities and work-processes (such as alternate transfection/ cell engineering strategies, media development, disposable/ closed production systems and automation), aligned with emerging business drivers and regulatory expectations.
  • Contribute to Project Technical Teams and communicate and collaborate effectively to ensure effective interactions with all stakeholder groups.
  • Ensure high-quality, timely documentation in electronic laboratory notebooks and Technical Reports and contribute to Regulatory Filings and responses to Regulatory questions as appropriate.
  • Present data/strategy to scientists (and management) in internal venues (technical meetings, Project Team meetings) as appropriate.
  • Remain current with the process engineering and chemistry literature. May collaborate and author external publications and present research at external conferences.

Position Requirements & Experience:

  • Ph.D. in Chemical Engineering, Biochemistry, Molecular & Cell Biology, Immunology or the related field with 5+ years or 7+ years (with M.S.) of relevant experience required.
  • Experience with prior Gene & Cell Therapy manufacturing preferred
  • A demonstrated foundational understanding of mammalian or primary cell culture, biochemistry, molecular & cell biology and immunology (required for enhanced product & process understanding).
  • Experience in genetic modification of cells using gene edit and gene delivery technologies.
  • Experience with continuous manufacturing processes including operation in upstream genetic modification and bioreactor/WAVE expansion, as well as downstream purification/separation, formulation/fill and cryopreservation.
  • Experience in media development, disposable processing technologies and automation of manufacturing processes.
  • Excellent knowledge of chemical engineering principles including: reaction kinetics, reactor design, chemical thermodynamics, heat and mass transport, engineering statistics, modeling and simulation.
  • Laboratory experience in a variety of analytical methods for the characterization and release of cell-based therapies, especially multi-parametric flow cytometry-based assays for characterization/ release/ stability testing preferred.
  • Hands-on expertise in processing of human peripheral blood mononuclear cells and the isolation and analysis of CAR T cells and T cell subsets and subpopulations preferred.
  • Proficiency in data analysis and interpretation using FlowJo and FACS Diva preferred.
  • Ability to work in a fast-paced, startup environment.
  • Strong attention to detail with the ability to multi-task and handle multiple responsibilities simultaneously.
  • Excellent organizational skills and an ability to prioritize effectively to deliver results within reasonably established timelines.
  • Ability to work independently and as part of a team.
  • Strong interpersonal skills including verbal and written communication are essential in this collaborative work environment.
