About this role
From the Claru listing
You'll draw precise segmentation masks over anatomical structures in CT scans, MRI slices, X-rays, and histopathology slides using DICOM-compatible tools such as OHIF Viewer or ITK-SNAP. Work includes labeling organs, lesions, tumors, and tissue boundaries at the pixel level, following detailed clinical annotation guides provided per project. Throughput expectations vary by modality — a straightforward chest X-ray organ label takes minutes, while a multi-class abdominal CT series can take 30–45 minutes per volume.

Common questions
What makes this one of Claru's higher-paying roles?
Claru bands its desk-based work by how much judgment a task needs. This listing sits in the top band at $55-$100/hr, alongside its RLHF evaluation, medical and 3D vision annotation and red-teaming roles, all of which expect graduate-level or professional depth in the subject and the ability to justify a score in writing. Its entry-tier text labeling sits at $20-$35/hr for comparison.
Is Claru desk work a steady queue or does it arrive in batches?
It comes in batches. You pick up a batch when you want, finish it and submit it, with no meetings. A new batch may not be waiting when you finish one, so plan for it as project income.
Does Claru publish the rate before I apply?
Yes. Every listing on claru.ai/jobs shows its hourly band on the card and again on the role page, so you can compare a $20-$35/hr labeling role against a $55-$100/hr evaluation role without creating an account first.
How does Claru measure quality on this kind of work?
Through agreement scoring and review. Its evaluation roles set a target for how closely your scores track other annotators, and disagreements with reviewers are resolved in an async comment thread you are expected to answer within a day. Steady, strong scores open the senior and lead tracks Claru mentions in its listings.
What does task-based AI training work look like?
Short, hands-on tasks such as recording videos, sorting images, rating AI answers or checking data. Most take 5 to 60 minutes each.
Can I choose my own hours?
Usually, yes. You log in when you want, pick up a task, finish it and submit it, with no meetings. Other people work from the same pool of tasks, so some days there may be no work until more is added.
What does Healthcare work look like for a Medical Image Segmentation Annotator?
You check AI answers to Healthcare questions, correct their errors and write expert reasoning. As a Medical Image Segmentation Annotator, you're hired for that judgment, so hands-on Healthcare experience matters.
What specific skills does this listing call for?
Data Annotation is named directly in the listing. If you don't have hands-on experience with this, expect the screening to test for it.
How much does this specific role pay?
This listing is posted at $55-100/hr, an hourly rate. Where you land in the range depends on your background and the assessment. Pay can change after we check the listing, so confirm the rate on the platform's application page.
What happens when I click Apply on this listing?
Apply opens Claru's site, where you create an account and follow its sign-up steps.
