Your impact
This is a part-time contract position . The contract is expected to run ~2–4 months , with an anticipated workload of ~10–15 hours per week (may vary based on program needs and consultant capacity).
The Machine Learning Annotation Content Developer will create high-quality instructional materials that teach modern data annotation and labeling workflows used to train and evaluate machine learning systems. The role will develop content across modalities—including text, image, video, audio/speech, and cross-modality labeling—translating real-world annotation tasks into clear, engaging, job-relevant learning experiences.
You will collaborate with our internal program team to produce session plans, hands-on practice, examples, and assessments aligned to defined learning outcomes. Content should model best-in-class annotation behavior: rule-based decisions, clear rationales, consistent application of guidelines, and appropriate handling of ambiguity (e.g., escalation rather than guessing).
A day in the life
Develop instructional lessons and training materials on:
- Text annotation (e.g., classification, NER, span annotation, summarization evaluation, safety/toxicity, dialogue evaluation)
- Image data annotation (e.g., bounding boxes, polygons, keypoints/landmarks, segmentation basics, quality checks)
- Video labeling (e.g., temporal segments, tracking, event labeling, frame sampling strategies)
- Audio and speech annotation (e.g., transcription conventions, speaker diarization concepts, intent/slot labeling, quality review)
- Cross-modality labeling (e.g., image-text matching, VQA-style labeling, grounding references across modalities)
Produce complete “content packages” per session/module (as applicable), such as:
- Facilitator guide, learner materials, demos or walkthroughs, practice activities, “strong vs. weak” examples, rubrics/evaluation criteria, and short knowledge checks/assessments
Create hands-on exercises using a common annotation platform (e.g., Label Studio or similar), including:
- Task setup guidance, labeling instructions, example labels, edge cases, and review workflows
Review and iterate on content based on internal feedback and peer review
Participate in weekly and ad hoc meetings with the program team to align on objectives, standards, and delivery constraints.
Support content deployment into our learning platform (training provided).
Your expertise
Required qualifications
- Demonstrated experience creating machine learning training content, instructional content, curriculum materials, or technical content for adult learners.
- Hands-on experience as a data annotator, including using tools such as Label Studio or similar annotation platforms.
- Ability to translate complex content into clear, learner-friendly lessons with concrete examples.
- Strong command of English (written and verbal) with excellent attention to detail and consistency.
- Organized, deadline-reliable, and comfortable working in a remote, fast-moving environment.
Nice to have
- Experience creating content across multiple data modalities (text, image, video, audio) and/or cross-modality tasks.
- Experience building rubrics, scoring guides, or evaluation criteria for annotation quality.
