The successful candidate will be enthusiastic, observant, collaborative, and dedicated, and will serve as a subject matter expert, applying their foundational immunology knowledge and experience to exciting, interdisciplinary efforts.

Draper offers a distinctive atmosphere that blends the best aspects from academia, government, and industry and that fosters innovation, a supportive team environment, intellectual freedom and creativity, and an emphasis on career development. The available position offers the potential for career growth and opportunities to take on more responsibilities over-time.

Key Responsibilities:

    Serve as an cell biologist and/or tissue bioengineer subject matter expert (emphasis on lung, liver, gastrointestinal, neural, and/or lymphoid tissue biology) for interdisciplinary teams including biologists, engineers, chemists, bioinformaticians, etc.
  • Plan and execute hands-on experiments in a BSL-2 lab with Draper's novel in vitro platform technologies (microphysiological system or organs-on-chip); train and supervise junior staff.
  • Lead mammalian cell and tissue culture and assay development; assist in troubleshooting experimental work in coordination with colleagues as needed.
  • Analyze, report, and present experimental data to internal management, external customers, and/or for publication.
  • Work across a broad spectrum of engineering and biological applications to solve our customers' most challenging needs including biodefense/biosecurity and medical countermeasure development applications.
  • Multitask within a dynamic and diverse project environment and adapt to changing priorities.
  • Support lab organization and maintenance as needed.


  • PhD in biomedical engineering, cell biology, stem cell biology, immunology or related field, with demonstrated understanding of human cell and tissue biology and advanced in vitro cell culture platforms.
  • Expertise in primary mammalian cell and tissue culture (human or animal), including complex multi-cell type co-culture, 3D cell culture/organoid biology, and/or stem cell culture.
  • Experience engineering tissue with resident immune cell populations, i.e. immune-competent tissue models.
  • Experience with primary-derived cell culture differentiation methodologies; phenotypic and functional characterization of tissue-specific and/or immunological cells; identification and/or understanding of key biomarkers for core tissue cell populations, and/or tissue-resident or blood-derived immune cell populations.
  • Expertise applying fundamental biology knowledge to novel in vitro cell culture systems such as microphysiological systems or organs-on-chip.
  • Experience with standard cell and molecular biological assays such as ELISA/Luminex, nucleic acid extraction, qPCR, immunofluorescence staining and confocal microscopy, cell proliferation/viability assays, cytotoxicity assays, flow cytometry / FACS, magnetic cell sorting.
  • Ability to solve complex problems with minimal supervision, adapt to changing priorities, interface with all levels of internal management, as well as program sponsors and subcontractors
