Contract Method Development Scientist – Fiber Length Characterization

Contract Method Development Scientist – Fiber Length Characterization

Location:

Onsite – Baltimore, MD
Engagement Type:

Contract / Temporary
Duration:

Approximately 2–3 months, with possibility of extension
Schedule:

Full‑time, onsite laboratory work
Pay Rate:

Competitive senior‑level contract rates (hourly)
Role Overview

We are seeking a

senior, hands‑on Method Development Scientist

to support development and optimization of analytical methods for measuring fiber length of

PCL nanofibers . This is a focused, project‑based contract role requiring strong experimental design skills, analytical judgment, and the ability to work independently in a laboratory setting.
Our current fiber length method involves SEM imaging with manual fiber tracing, which suffers from variability due to inconsistent sample preparation, fiber entanglement, and subjective interpretation. We are evaluating more robust and potentially automated approaches, including image‑based particle analysis using a

Malvern Morphologi

system and/or alternative techniques. The successful candidate will own the evaluation, optimization, and recommendation of a go‑forward method.
This role is

onsite and hands‑on , not remote or execution‑only.
Key Responsibilities

Evaluate limitations and variability sources in current SEM‑based fiber length measurement methods
Design and execute experiments to improve sample preparation, fiber dispersion, and measurement reproducibility
Assess feasibility of automated or semi‑automated image‑based approaches (e.g., Malvern Morphologi or similar systems) for fibrous materials
Define objective criteria for identifying individual fibers versus aggregates or intertwined fibers
Conduct side‑by‑side method comparisons (manual vs automated approaches) with appropriate data analysis
Troubleshoot method variability using hypothesis‑driven experimentation
Summarize findings in clear, well‑organized technical documentation
Provide data‑driven recommendations on method readiness, limitations, and next steps toward validation
Required Qualifications

B.S., M.S., or Ph.D. in Chemistry, Materials Science, Biomedical Engineering, Chemical Engineering, or a related field
Demonstrated

hands‑on method development experience

for particle, fiber, or morphology analysis
Strong understanding of microscopy, image analysis, and sample preparation challenges
Experience working with

polymeric materials, fibers, or nanomaterials
Proven ability to independently design experiments, interpret data, and troubleshoot variability
Ability to clearly document and communicate technical decisions and conclusions
Preferred / Nice‑to‑Have Experience

Experience with Malvern Morphologi or similar image‑based particle analysis systems
SEM experience with fibrous or soft materials
Experience transitioning manual, subjective methods into more robust or automated workflows
Familiarity with regulated or GMP‑adjacent laboratory environments
What Success Looks Like

Reduced subjectivity and variability relative to current SEM‑based method
Clear understanding of strengths, limitations, and applicability of automated image‑based approaches
Optimized sample preparation and measurement workflow(s)
Written recommendation for a defensible fiber length measurement strategy suitable for further development or validation
