Contract Method Development Scientist – Surface Chemistry

LifeSprout • Baltimore, MD

5d • Onsite

About The Position

LifeSprout is a medical device company developing innovative biomaterial products for aesthetic and reconstructive medicine. Our synthetic biomaterial platform is designed to mimic the look and behavior of native tissue and is being advanced into products intended to restore form and function for patients with soft tissue loss. We are seeking a highly capable contract scientist to support a focused analytical method development and validation project in a fast-paced, hands-on environment.

LifeSprout is opening a short-term contract role (approximately 2–3 months) for a hands-on Method Development Scientist to lead improvement and validation of a colorimetric analytical method, specifically an Ellman’s assay for quantification of surface bound thiol groups . This role requires a strong analytical chemistry background and the ability to independently assess an underdeveloped assay, improve its performance, and deliver a validated method package suitable for internal use. The ideal candidate brings deep experience in colorimetric or spectrophotometric assay development, method troubleshooting, and formal validation in a regulated environment.

Requirements

• PhD or MS with significant relevant experience in Analytical Chemistry, Chemistry, Chemical Engineering, Materials Science, Biomedical Engineering, or a related scientific discipline.
• Demonstrated hands-on experience in analytical method development, optimization, and validation in regulated laboratory environments such as medical device, biotechnology, pharmaceutical, or GMP/ISO 13485 settings.
• Strong analytical chemistry background with direct experience in colorimetric and/or spectrophotometric method development.
• Experience improving assay sensitivity, precision, and overall robustness, including work related to LOD/LOQ or comparable performance characteristics.
• Direct experience authoring and executing validation protocols, SOPs, work instructions, and validation reports.
• Knowledge of validation concepts such as accuracy, precision, linearity, range, specificity, and robustness.
• Knowledge of statistical approaches for method evaluation, acceptance criteria, and data analysis.
• Excellent technical writing, data interpretation, and troubleshooting skills.
• Ability to work independently with minimal oversight and drive work to completion on an accelerated timeline.
• Eligibility to work in the U.S. is required.

Responsibilities

• Assess, troubleshoot, and improve an existing colorimetric assay, including identification of factors affecting sensitivity, robustness, and reproducibility.
• Design and execute method development experiments to optimize assay conditions, sample preparation, reagents, and analytical parameters.
• Improve method performance with emphasis on sensitivity, precision, and practical limits of detection and quantitation.
• Plan, author, and execute method validation protocols and generate defensible validation reports.
• Draft and revise SOPs, work instructions, and supporting technical documentation required for internal method implementation.
• Summarize data clearly, interpret results scientifically, and recommend next steps based on sound analytical reasoning.
• Collaborate cross-functionally as needed while operating with a high degree of independence in a short-term contract setting.
• Deliver a complete, validated method package ready for internal laboratory use.
