Job description

Role Title: Materials Scientist (Nanoparticle Sizing & Lot Release)

Role Type: Contractor

Location: Remote

micro1 is engaging Materials Scientists (Nanoparticle Sizing & Lot Release) to contribute specialized expertise to a customer’s project focused on advanced nanomaterial evaluation. 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.

Scope of Work

1. Manually analyze and interpret TEM and SEM micrographs for nanoparticle sizing and morphological assessment
2. Determine and document particle size distributions (PSD) with rigorous attention to accuracy and reproducibility
3. Establish and communicate lot-release acceptance criteria based on technical reference cases and quality control standards
4. Prepare detailed reports summarizing findings, methodologies, and recommendations for material qualification
5. Validate measurement techniques through manual calibration, thresholding, and cross-checking against reference data
6. Participate in technical discussions, providing expert insights on nanomaterial characterization and quality control criteria
7. Deliver clear, concise written and verbal communications to facilitate knowledge transfer across project teams

Preferred Qualifications

1. Advanced knowledge of nanomaterial characterization, especially using TEM and SEM
2. Demonstrated hands-on experience in nanoparticle sizing, particle size distribution analysis, and lot release evaluation
3. Proficiency with manual image analysis, including thresholding, calibration, and interpretation of complex morphologies
4. Strong understanding of quality control standards and reference material qualification protocols
5. Exceptional written and verbal communication skills for reporting and collaboration
6. Ability to evaluate and validate technical reference cases without the use of AI-based tools
7. Background in scientific consulting, materials science, or laboratory-based analytical roles is a plus
