Scientist - Cell Biology

Position Overview: The Javelin Biotech R&D team is seeking a talented and motivated individual with experience in cell biology and Complex In Vitro Models (CIVM). The R&D team is responsible for developing tissue models which recapitulate the phenotypic and molecular functions that are important to drug discovery and development. This role is for an early-career scientist with a passion for advancing and characterizing primary human tissue models using cutting-edge biomaterials, advanced imaging techniques, and establishing assays for tissue function and application-specific requirements. Expertise in primary human cells (emphasis on liver, kidney, and/or gastrointestinal tissue biology) and molecular biology techniques, including quantitative polymerase chain reaction (qPCR), ELISA/immuno-assays, and immunohistochemistry, are integral to this position. The successful candidate will apply their scientific experience towards expanding our in vitro modeling capabilities for new pharmacological applications.


Responsibilities:

  • Design, develop, and validate complex 3D in vitro models using biomaterials and scaffold, including normal and diseased tissue, using Javelin’s tissue chip platform

  • Conduct experiments using cell biology and bioengineering tools (primary human tissue culture, microscopy, biochemical/immuno-based assays, qPCR)

  • Develop and apply immunofluorescence and immunohistochemistry (IHC) staining protocols optimized for complex 3D constructs and execute advanced imaging workflows including confocal microscopy, electron microscopy, and high-content imaging to characterize tissue models in 2D and 3D

  • Quantify morphological and phenotypic endpoints using image analysis pipelines (e.g., CellProfiler, FIJI/ImageJ, Imaris). Independently design and execute studies, analyze and interpret data, and present findings back to the project team

  • Collaborate and communicate data clearly and concisely within a multidisciplinary team, including tissue engineering, hardware engineering, computational biology, and product development

  • Stay current with the latest advancements in CIVM and contribute to the development of innovative approaches and contexts-of-use

  • Assist in writing and preparation of grant proposals, manuscripts, and reports and participate in professional activities related to research

  • Provide mentorship and training for team members in specialized protocols and equipment use. Contribute critical scientific input to experiment designs.


Qualifications:

  • PhD degree in Cellular or Molecular Biology, Bioengineering, Chemical Engineering, or a related discipline with 1-3 years of relevant experience. Appointment level will depend on skill set and years of experience.

  • Outstanding laboratory technique: primary human cell culture; microscopy (phase contrast, fluorescence, and confocal), protein and gene expression analysis, immuno-, biochemical & bioanalytical assays

  • Strong experience with primary human complex in vitro models (liver, kidney, gut) including microphysiological systems, biomaterials, iPSCs, 3D cultures, spheroids, and organ-on-chip; experience with extracellular matrix biology, immune components and disease models is a strong plus

  • Advanced microscopy and imaging expertise, including confocal and fluorescence microscopy in 3D tissue contexts is required. Proficiency in image analysis software (FIJI, CellProfiler, Imaris, or equivalent)

  • Familiarity with ADME/Tox assays, drug metabolism studies, or nephrotoxicity/hepatotoxicity screening

  • Detail-oriented and scientifically driven with solid reasoning skills in experimental design, data analysis, and interpretation

  • Excellent written and verbal communication skills; ability to follow complex instructions, multitask, carefully document work in written records.

  • Strong data analysis and statistical skills (e.g., Prism, R-studio, etc.)

  • Able to work well under direction as well as independently to achieve scientific and corporate milestones

  • Demonstrated ability to work in a cross-functional team and/or lead a small team effectively in a multidisciplinary, fast-paced, dynamic, and results-oriented environment

  • Available to start within 4-6 weeks


Compensation:
Javelin Biotech offers a compensation package that includes a competitive salary based on experience, full health insurance, company contribution for dental and vision insurance, company match 401(k), and stock options.

Job type: permanent, full-time, on-location

 Javelin Biotech is an equal opportunity employer and welcomes candidates from diverse backgrounds to apply.
