What is the difference between Manager Plant Science vs Plant Biologist?

AspectManager Plant SciencePlant Biologist
Required CredentialsBachelor's or Master's in Plant Science, Agriculture, or related field; often requires leadership experienceBachelor's, Master's, or Ph.D. in Plant Biology, Botany, or related field; research-focused
Work EnvironmentResearch facilities, agricultural companies, or corporate R&D departments; managerial roleUniversities, research institutes, or laboratories; primarily research and experimentation
Employer & Industry UsageAgri-business, biotech firms, research organizations; overseeing projects and teamsAcademic institutions, government agencies, research centers; conducting scientific studies

The main difference is that a Manager Plant Science oversees research projects and teams within agricultural or biotech companies, focusing on management and application. In contrast, a Plant Biologist primarily conducts scientific research to understand plant biology, often in academic or research settings. Both roles require strong knowledge of plant sciences, but their responsibilities and work environments differ significantly.

Job description

Job Description
About Allogene:
Allogene Therapeutics, with headquarters in South San Francisco, is a clinical-stage biotechnology company pioneering the development of allogeneic chimeric antigen receptor T cell (AlloCAR T) products for cancer and autoimmune disease. Led by a management team with significant experience in cell therapy, Allogene is developing a pipeline of "off-the-shelf" CAR T cell product candidates with the goal of delivering readily available cell therapy on-demand, more reliably, and at greater scale to more patients.
About the role:
Allogene is seeking a highly motivated Principal Scientist to lead the Pilot Plant function within Process & Product Development (PPD). This individual will serve as a technical and operational leader responsible for translating process development strategies into robust, scalable pilot-scale operations.
This successful candidate will leverage deep expertise in process development and scale-up to lead complex studies, guide organizational strategy, and drive cross-functional integration with Drug Product, MSAT, and Manufacturing. This role requires strong scientific leadership, operational execution, and the ability to influence programs across the organization.
Responsibilities include, but are not limited to:
  • Lead the Pilot Plant team, overseeing execution of large-scale and engineering runs in support of process development, characterization, and technology transfer.
  • Translate process development strategies into robust, executable at-scale cell therapy manufacturing operations.
  • Ensure alignment across development, pilot, and manufacturing functions, enabling robust technology transfer to GMP.
  • Lead the design and execution of high-impact process development and characterization studies using QbD principles.
  • Identify and mitigate scale-dependent risks associated with cell therapy manufacturing platforms (e.g. Sepax, Xuri, Prodigy, etc), ensuring robust process performance upon scale-up.
  • Apply engineering principles, including fluid dynamics and gas and mass transfer, to support process understanding, scale-up, and robust manufacturing performance.
  • Develop and implement closed, aseptic, automation strategies, including equipment/system evaluation, programming and optimization of cell therapy platform-specific systems
  • Drive end-to-end process integration, including thaw, activation genetic engineering, cell expansion, and fill/finish unit operations and associated at-scale equipment.
  • Serve as the primary Process Sciences interface with Drug Product, Manufacturing, and MSAT functions.
  • Ensure high-quality, timely documentation in electronic laboratory notebooks and Technical Reports and contribute to Regulatory Filings and responses to Regulatory questions as appropriate.
  • Author and/or oversee preparation of technical reports, regulatory documents (i.e. IND/BLA sections), and scientific publications.
  • Interpret complex datasets and communicate results to cross-functional teams and senior leadership.
  • Act as a technical mentor, coaching scientists on study design, data interpretation, and scientific decision-making.
  • Remain current with relevant cell therapy, immunology, and bioprocessing literature.
  • Other duties as assigned

Position Requirements & Experience:
  • Ph.D in Chemical Engineering, Bioengineering, Biochemistry, Molecular & Cell Biology, Immunology or related field with at least 7 years of relevant experience required; or MS with at least 10 years of industry experience; or BS with at least 12 years of industry experience.
  • Extensive experience in process development and scale-up for biologics or cell therapy manufacturing.
  • Demonstrated expertise in process characterization, DOE, and data-driven decision making.
  • Experience using Python or R for analysis of complex datasets and development of automation solutions for cell therapy manufacturing platforms.
  • Strong understanding of cell therapy manufacturing processes (i.e. gene editing, viral transduction, cell expansion, formulation).
  • Experience supporting regulatory filings (IND/BLA) and process validation (PPQ).
  • Proven track record of leading complex technical programs and cross-functional initiatives.
  • Strong leadership, mentorship, and cross-functional collaboration skills.
  • Strong written and verbal communication skills, including authoring technical documents and presenting to senior leadership.
  • Candidates must be authorized to work in the U.S.

We offer a chance to work with talented people in a collaborative environment and provide a top-notch compensation and benefits package, which includes an annual performance bonus, equity, health insurance, generous time off (including 2 annual holiday company-wide shutdowns) and much more. The expected salary range for this role is $155,000 - $180,000 per year. Actual pay will be determined based on experience, qualifications, geographic location, business needs, and other job-related factors permitted by law.
As an equal opportunity employer, Allogene is committed to a diverse workforce. Employment decisions regarding recruitment and selection will be made without discrimination based on race, color, religion, national origin, gender, age, sexual orientation, physical or mental disability, genetic information or characteristic, gender identity and expression, veteran status, or other non-job-related characteristics or other prohibited grounds specified in applicable federal, state and local laws. We also embrace differences in experience and background, and welcome diversity of opinions and thought with active recruitment and internships designed to create a stronger and better Allogene that is focused on developing life-changing products for patients.
