Job Description

Job Title: Scientist – Medical Device Toxicology (CRO)
Job Description

This role focuses on preparing and testing a wide range of medical devices within a contract research organization (CRO) environment to support in vivo toxicology studies and help advance treatments, including therapies for cancer. The scientist handles devices ranging from simple solid materials to complex implants, such as tubes, syringes, and various plastic components, and prepares extracts in accordance with ISO standards and Good Laboratory Practices (GLP). This position requires a hands-on leader who brings strong technical expertise in medical device extraction, supports and trains less experienced staff, and maintains meticulous documentation while working in a fast-paced, client-driven setting.

Responsibilities

• Receive, evaluate, and process medical device test articles submitted for testing.
• Review incoming devices to determine appropriate tests and preparation procedures in accordance with ISO standards and internal protocols.
• Confirm that all required instructions and documentation accompany each device and verify surface area measurements and related details.
• Determine the surface area of each device or device component and calculate the required extraction ratio for testing.
• Prepare extractions from medical devices, creating liquid extracts that will be dosed to animals in toxicology studies.
• Handle a broad range of devices, such as syringes, tubing sets, and other components, including measuring and calculating surface areas for partial or fully submerged configurations while excluding non-relevant parts (for example, end caps that do not contact the patient).
• Prepare samples and dosing solutions using aseptic technique and in strict accordance with standard operating procedures and study protocols.
• Coordinate and communicate sample preparation and scheduling with scientific staff and Study Directors to align with study timelines and changing client needs.
• Run assays and execute scheduled laboratory activities as outlined in weekly study schedules and protocols.
• Participate in dosing studies in the vivarium, including obtaining animal body weights and administering test materials via appropriate routes such as intravenous injection.
• Monitor and observe animals following dosing, including wrapping or restraining animals when needed to ensure proper handling and safety.
• Perform single-injection studies and related observations, documenting all procedures and outcomes accurately.
• Meticulously maintain precise, complete, and accurate records of all preparations, dosing activities, and assay results in compliance with GLP requirements.
• Perform basic mathematical calculations to support surface area determinations, extraction ratios, and dosing calculations.
• Maintain a clean, organized, and well-documented work area to support efficient and compliant study execution.
• Follow all laboratory and facility safety requirements, including the ability to safely wear a respirator when needed.
• Lead and mentor less experienced personnel, providing training on device preparation, extraction techniques, documentation practices, and GLP expectations.
• Adapt to a fast-paced, schedule-driven environment where priorities may shift based on client demands.
• Support cage wash and cleaning activities related to animal studies as needed to maintain a compliant and sanitary environment.
• Contribute to study reporting by providing accurate data, documentation, and assay results to scientific staff and Study Directors.

• Direct hands-on experience preparing extracts of medical devices in a contract research organization (CRO) environment.
• Practical experience handling a variety of medical devices, from simple components to complex implants, for testing and extraction.
• Working knowledge and application of ISO standards related to medical device testing and extraction.
• Strong understanding and practice of Good Laboratory Practices (GLP), with the ability to maintain meticulous and accurate records.
• Experience preparing dosing solutions and extractions that are administered to animals in toxicology studies.
• Hands-on experience with toxicology-related procedures, including dosing and in vivo study support.
• Ability to perform basic mathematical calculations, including surface area determinations and extraction ratio calculations.
• Proven ability to follow detailed written and verbal instructions, standard operating procedures, and study protocols.
• Demonstrated integrity, strong sense of responsibility, and commitment to ethical and compliant laboratory work.
• Strong organizational skills with the ability to manage a broad spectrum of responsibilities in a fast-paced environment.
• Capability to work independently while also collaborating effectively with scientific staff and Study Directors.
• Ability to safely wear a respirator when required by specific tasks or safety protocols.

• Leadership experience in a laboratory or CRO setting, including mentoring and training less experienced staff.
• Experience working directly with animals in a vivarium setting, including dosing, body weight collection, and observation.
• Familiarity with intravenous (IV) dosing and related dosing techniques in animal studies.
• Background in toxicology, pharmacology, or related life sciences disciplines.
• Experience with medical device preparation for testing, including disassembly, extraction practices, and readiness for ISO-compliant testing.
• Comfort working in a fast-paced environment with changing schedules driven by client needs.
• Strong attention to detail in paperwork, documentation, and record-keeping to support GLP compliance.
• Ability to communicate clearly and professionally with cross-functional scientific teams.
• Motivation to contribute to research that supports the development of therapies, including those aimed at curing cancer.

The role is based within a contract research organization (CRO) that conducts animal studies and medical device testing in a vivarium and laboratory setting. The environment is fast-paced and schedule-driven, with priorities that may shift based on client timelines and study requirements. You will work hands-on with medical devices, laboratory equipment, and animal dosing setups, following ISO standards, GLP, and strict safety protocols. The position involves close collaboration with scientific staff and Study Directors, as well as leadership and training responsibilities with less experienced team members. The work includes time in animal facilities, cage wash and cleaning support as needed, and adherence to all facility safety requirements, including the use of personal protective equipment and respirators when required. The culture emphasizes scientific rigor, integrity, meticulous documentation, and a shared commitment to advancing research that supports treatments for serious diseases, including cancer.
