It's an excellent opportunity for students or recent graduates to gain practical skills and exposure to real-world research and development environments.

What types of projects or experiments might an internship assay development scientist typically be involved in during their internship?

As an Internship Assay Development Scientist, you can expect to participate in hands-on projects focused on the design, optimization, and validation of biochemical or cell-based assays. Your daily tasks may include preparing reagents, running experiments, analyzing data, and troubleshooting protocols under the guidance of experienced scientists. Interns often collaborate closely with cross-functional teams, such as research scientists and quality control specialists, to ensure assay reliability and accuracy. This role offers a valuable opportunity to refine laboratory techniques, gain exposure to industry-standard instrumentation, and contribute to real-world research projects.

What are the key skills and qualifications needed to thrive as an internship assay development scientist, and why are they important?

To thrive as an Internship Assay Development Scientist, you need a solid understanding of molecular biology, biochemistry, and laboratory techniques, typically supported by coursework or experience in a related scientific field. Familiarity with laboratory equipment, data analysis software (like GraphPad Prism or Excel), and adherence to safety protocols is often required. Strong attention to detail, problem-solving abilities, and effective communication skills set candidates apart in collaborative research environments. These competencies ensure accurate experiment execution, reliable data generation, and valuable contributions to assay development projects.

What is the difference between Internship Assay Development Scientist vs Laboratory Technician?

AspectInternship Assay Development ScientistLaboratory Technician
Required CredentialsTypically pursuing or holding a bachelor's or master's degree in life sciences; internship experienceAssociate degree or relevant technical training; less emphasis on advanced degrees
Work EnvironmentResearch labs focused on assay development, often in biotech or pharma companiesGeneral lab settings performing routine testing and sample preparation
Employer & Industry UsageUsed in biotech, pharmaceutical, and research organizations for early-career rolesCommon across various industries for lab support roles

The Internship Assay Development Scientist role focuses on gaining experience in assay design and validation within research environments, often requiring higher education. In contrast, Laboratory Technicians perform routine lab tasks with less emphasis on assay development, serving as support staff in various industries.

Job description

About AcelaBio
AcelaBio is a CAP- and CLIA-accredited specialty histopathology laboratory based in San Diego, CA. We deliver anatomic histopathology, immunostaining, digital image analysis, spatial transcriptomics, and biomarker endpoints to pharmaceutical and biotechnology sponsors. Our team is scientifically driven, client-focused, and committed to advancing translational research through rigorous, reproducible methods.
About the opportunity
This is a high-impact, technically hands-on role at the intersection of immunostaining assay development, quantitative image analysis, and client science. You will build and optimize IHC, multiplex IF, and ISH assays from the ground up, develop and maintain AI-assisted image analysis pipelines, and serve as a scientific lead for sponsor studies across preclinical and clinical programs.
You will work directly with pathologists, laboratory technicians, project operations, and business development teams, and will be a visible scientific partner to our pharmaceutical and biotechnology clients. If you are someone who thrives on solving complex assay challenges, values scientific rigor, and enjoys translating data into clear, actionable insights for sponsors, this role is built for you.
Role Logistics: On-site, San Diego (required). Travel expectations ~ 10%
Responsibilities
  • What you'll be doing:

Assay Development, Image Analysis (Core Focus):
  • Design, develop, optimize, and validate immunostaining assays including single-plex IHC, multiplex immunofluorescence (mIF), in situ hybridization (ISH), and spatial biology platforms.
  • Define analytical endpoints, scoring strategies, and QC metrics aligned with assay performance requirements.
  • Develop, validate, and maintain image analysis pipelines using platforms such as Visiopharm, HALO, or equivalent software.
  • Build and implement AI/machine learning algorithms for tissue segmentation, cell phenotyping, and biomarker quantification.
  • Ensure traceability, reproducibility, and thorough documentation of all analysis workflows.
  • Contribute to assay validation documentation, analytical reports, and regulatory-aligned deliverables.
  • Partner with histotechnicians to support hands-on assay troubleshooting and knowledge transfer
Scientific Leadership & Client Engagement;
  • Serve as a scientific interface for sponsors, participating in protocol reviews, study design discussions, and data review meetings.
  • Provide expert guidance on biomarker study design incorporating omics and non-omics endpoints.
  • Prepare and review project plans, analysis plans, study reports, abstracts, and technical manuscripts.
  • Deliver clear, scientifically rigorous data visualizations, analyses, and summaries tailored to sponsor audiences

Business Development and Innovation:
  • Support RFP responses, project pricing, protocol review, and bid defense activities.
  • Contribute to the development of sales, marketing, and promotional scientific content.
  • Drive continuous improvement of our computational pathology, spatial biology, and translational research service offerings.
  • Participate in capability development and functionality reviews to expand the AcelaBio service portfolio.

Qualifications
  • Education and Experience:
    • Graduate degree (M.Sc. or Ph.D.) in a relevant scientific discipline (pathology, cell biology, molecular biology, biomedical engineering, or related field).
    • 7 or more years of hands-on experience in IHC/IF assay development and image analysis in a CRO, biopharma, or regulated research environment.
    • Demonstrated experience building image analysis algorithms or pipelines in platforms such as Visiopharm, HALO, or similar.
    • Exposure to spatial biology platforms (e.g., 10x Visium, Xenium, Akoya PhenoCycler) is a strong asset.
  • Technical Skills & Competencies:
    • Deep practical knowledge of chromogenic IHC and multiplex immunofluorescence, including antibody selection, panel design, optimization, and troubleshooting.
