What is a data annotation intern?

Data Annotation Interns are entry-level professionals who assist in labeling and categorizing data, such as images, audio, or text, to help train machine learning models. Their work is crucial for ensuring that AI systems can accurately interpret and process various types of data. Interns typically use specialized software tools to annotate data according to specific guidelines, and they may also help with data quality checks. This position is ideal for those interested in gaining experience in artificial intelligence, data science, or related fields.

What are the key skills and qualifications needed to thrive as a data annotation intern, and why are they important?

To thrive as a Data Annotation Intern, you need strong attention to detail, basic computer literacy, and familiarity with data labeling concepts, often supported by a background in computer science or related fields. Familiarity with annotation tools like Labelbox, Supervisely, or CVAT and understanding of data formats such as JSON or XML are typically required. Effective communication, time management, and the ability to follow complex guidelines are important soft skills for this role. These skills ensure high-quality, consistent data labeling, which is crucial for training accurate machine learning models.

What are some common challenges faced by data annotation interns and how can they be overcome?

Data Annotation Interns often encounter challenges such as maintaining consistency and accuracy when labeling large volumes of data, especially when guidelines evolve or when dealing with ambiguous cases. To overcome these challenges, it's important to frequently review annotation guidelines, communicate proactively with supervisors or team members for clarification, and participate in regular quality checks. Collaborating with experienced annotators and leveraging feedback provided during peer reviews can also help interns improve their accuracy and efficiency.

What is the difference between Data Annotation Intern vs Data Labeling Specialist?

AspectData Annotation InternData Labeling Specialist
CredentialsTypically pursuing or recent graduate in related fieldRelevant experience or certifications in data labeling
Work EnvironmentInternship setting, often in tech or AI companiesFull-time or freelance roles in data annotation projects
Industry UsageCommon in tech, AI, and machine learning industriesUsed across similar industries for data preparation
Job FocusLearning and assisting with data annotation tasksPerforming detailed data labeling and quality control

While both roles involve working with data annotation, a Data Annotation Intern is typically a beginner or student gaining experience, whereas a Data Labeling Specialist is a more experienced professional focused on precise data labeling tasks. Interns often work under supervision, while specialists handle independent projects.

Is it hard to get hired for data annotation intern?

Getting hired as a data annotation intern can be competitive but generally requires basic skills in data labeling, attention to detail, and familiarity with annotation tools. Many positions are entry-level and may not require extensive experience, making the application process accessible to beginners with relevant skills or coursework.

Job description

2027 Spring Intern - OpRegen Machine Learning

Department Summary

The OpRegen ML team develops machine learning tools that help us understand the biology behind the OpRegen manufacturing process and give our teams objective, quantitative metrics where today we rely on infrequent and subjective observation. OpRegen is an allogeneic hESC-derived cell therapy in development for geographic atrophy (advanced dry AMD), manufactured through hESC expansion, RPE differentiation, and RPE expansion. We're building ML models to capture cell morphology from routine microscopy images, non-invasively and at scale.

This internship position is located in South San Francisco, on-site.

The Opportunity


This internship centers on our in-house morphology capability, a platform we call Cellestial. The core opportunity is to turn generated imaging data into insight - running our models across the images and exploring the results for correlations with phenotypic properties - and to help extend the capability further.

The intern will work closely with our computational team and with the wet-lab, Process Development, and gRED scientists who generate the data and act on the results. This internship offers the opportunity to shape the specifics around the intern's strengths and interests, anchored to the core deliverable of analyzing the already obtained images.

  • Data analysis and insight - exploring the imaging data for correlations between morphological features and phenotypic properties, and reporting the findings

  • Model deployment and automation - helping automate inference on new data using our compute infrastructure, so results are generated as data arrives

  • Visualization and tooling - building tools to explore results and connect them back to their experimental context

  • Translation to the process - working with our lab, Process Development, and manufacturing partners to identify the metrics that matter most

  • Applied research - collaborating with research scientists on questions the morphology data can help answer

  • Data annotation and modeling - annotating additional imaging data and contributing to related model work

Program Highlights

  • Intensive 6 months, full-time (40 hours per week) paid internship.

  • Program start dates are in January 2027 (Spring).

  • A stipend, based on location, will be provided to help alleviate costs associated with the internship.

  • Ownership of challenging and impactful business-critical projects.

  • Work with some of the most talented people in the biotechnology industry.
