Bengali Data Trainer

Scope of Work Review existing translations of English-source ARC benchmark science questions into the Bengali language. Each item will include the original translation and an AI-proposed correction. This is a review/QA task, not a from-scratch translation task. Review only two translatable elements: the question/stem and the answer choices. Instructions, explanations, and other associated text are out of scope. Compare both the original translation and AI-proposed correction against the English source and assign exactly one of the following labels: Accept original Accept AI correction Edit final – provide the corrected question and choices Escalate – when the item cannot be safely reviewed, such as mismatched choice count/order, indistinguishable choices, or display issues.

CBRN Safety & Risk Evaluation Specialist

##Role: We are looking for experienced technical professionals to help review and improve AI-generated content in chemical, biological, radiological, and nuclear (CBRN) safety. The work combines subject-matter judgment with careful written evaluation: you will check whether model responses are technically sound, appropriately cautious, and useful without crossing into unsafe or overly operational guidance. MANDATORY REQUIREMENT: All trainers must be a citizen of, currently reside in, or both, one of the Five Eyes (FVEY) countries: United States, Canada, United Kingdom, Australia, or New Zealand. Candidates who do not meet this requirement are not eligible for this role. ##What You’ll Do -Review AI-generated technical content: Check responses on CBRN, hazardous materials, emergency preparedness, and public-safety topics for technical accuracy, clarity, and safe framing. -Spot unsafe or misleading guidance: Identify content that is overly procedural, enables harmful activity, gives inappropriate acquisition or evasion guidance, misstates exposure risks, or provides unsafe laboratory or emergency advice. -Write and improve reference answers: Create or refine high-quality examples that answer legitimate questions clearly while staying within appropriate safety boundaries. -Compare and rank model responses: Judge which response is stronger based on factual accuracy, risk framing, usefulness, refusal quality when needed, and overall clarity. -Catch technical errors: Flag hallucinated facts, incorrect hazard classifications, unsupported conclusions, poor escalation advice, misleading risk statements, or misuse of technical terminology. -Apply project guidance consistently: Use project rubrics and review standards in a repeatable way and explain your decisions in concise written feedback. -Escalate sensitive cases: Recognize when an item is ambiguous, high risk, or outside the expected review boundary and route it for additional review. ##What We’re Looking For Bachelor’s degree or higher in a relevant technical field, or equivalent professional experience. Strong matches include Chemistry, Biochemistry, Physics, Nuclear Physics, Engineering, Materials Sciences, and closely related disciplines.

Egocentric Activity Capture: First-Person Video Data Collection

This project collects real-world, first-person (egocentric) video of people performing everyday tasks, captured from head-mounted or chest-mounted cameras. The footage is used to train and evaluate models that need to understand human activity from the wearer's point of view: hand-object interaction, task sequencing, spatial awareness, and intent prediction. Contributors record short, unscripted clips of themselves completing routine activities in natural settings: cooking, cleaning, assembly and repair, shopping, office work, tool use, and similar. Each recording follows a defined scenario brief covering environment, task, duration, lighting conditions, and camera placement, and is delivered with a metadata sheet (device, resolution, frame rate, location type, consent record). Where required, sessions include synchronized sensor streams such as IMU. We are looking for resources who can support: participant recruitment, on-site or at-home recording, scenario scripting, and post-capture QC against the collection guidelines. Volume, target locations, and per-scenario requirements are defined per batch.
