In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters. This opportunity centers on thorough nanoparticle sizing, particle size distribution analysis, and lot release qualifications using Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM). The engagement emphasizes independent expert analysis — including manual image thresholding, calibration, and morphology assessments — without reliance on automated or AI-powered tools. Strong written and verbal communication skills are essential to document findings, interpret complex micrographs, and convey critical decisions to project stakeholders.\nScope of Work\nManually analyze and interpret TEM and SEM micrographs for nanoparticle sizing and morphological assessment\n\nDetermine and document particle size distributions (PSD) with rigorous attention to accuracy and reproducibility\n\nEstablish and communicate lot-release acceptance criteria based on technical reference cases and quality control standards\n\nPrepare detailed reports summarizing findings, methodologies, and recommendations for material qualification\n\nValidate measurement techniques through manual calibration, thresholding, and cross-checking against reference data\n\nParticipate in technical discussions, providing expert insights on nanomaterial characterization and quality control criteria\n\nDeliver clear, concise written and verbal communications to facilitate knowledge transfer across project teams\n\nPreferred Qualifications\nAdvanced knowledge of nanomaterial characterization, especially using TEM and SEM\n\nDemonstrated hands-on experience in nanoparticle sizing, particle size distribution analysis, and lot release evaluation\n\nProficiency with manual image analysis, including thresholding, calibration, and interpretation of complex morphologies\n\nStrong understanding of quality control standards and reference material qualification protocols\n\nExceptional written and verbal communication skills for reporting and collaboration\n\nAbility to evaluate and validate technical reference cases without the use of AI-based tools\n\nBackground in scientific consulting, materials science, or laboratory-based analytical roles is a plus\n\nOriginally posted
