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

Role Type: Contractor

Location: Remote

our partner 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

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

Preferred Qualifications

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

This is a 100% remote contract role, open to applicants worldwide in the countries the employer accepts.

What to know before you apply

Pay
At the published rate, 10 hours a week would be about $400–$1,000 and 20 hours about $800–$2,000 before tax. Hours depend on the project, so treat this as a ceiling, not a promise.
Openings
Only 1 opening. Shape your CV around the requirements above so a reviewer sees the match in seconds.
Location
Open worldwide in the countries the employer accepts. Payments usually go out through services like PayPal or Wise, so check one of them works in your country.
Timing
This listing is new today. Projects can close once they have enough people, so it is worth applying while it is open.
Test tips for scientists & researchers
  • Show full derivations; partial reasoning is usually marked down.
  • Check units, assumptions and limiting cases in every AI solution.
  • Write hard original problems that break the model: that skill is in demand.
