Contract Method Development Scientist

About LifeSprout
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.

Position Overview
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.

Key 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.

Required Qualifications

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.

Working Conditions and Logistics
This is an on-site contract position based in Baltimore, Maryland, with an expected duration of approximately 2–3 months. The role requires regular laboratory presence and a high level of hands-on execution. The successful candidate will be expected to move quickly, apply strong scientific judgment, and deliver high-quality technical documentation and validated results within a short project timeline.

Eligibility
Eligibility to work in the U.S. is required.

LifeSprout offers the opportunity to make a direct technical impact on an important analytical development project supporting innovative biomaterial products.
This position is best suited for a scientist who combines strong experimental ownership with deep analytical chemistry expertise and proven success in colorimetric method development and validation.
We are looking for someone who can quickly assess, improve, validate, and document a method with minimal supervision in a contract setting.
