The Medical Device Toxicologist will serve as a scientific leader and subject matter expert for the biological safety evaluation of medical devices, combination products, materials, and components across the product lifecycle. The role will develop risk-based biocompatibility strategies, integrate chemical and biological evidence, and translate complex toxicology data into clear product-safety conclusions and global regulatory positions. The successful candidate will pair medical device toxicology expertise with toxicology judgment, strategic problem solving, cross-functional leadership, and effective oversight of external laboratories and consultants. This role is on-site in Fort Worth, Texas and would include: Lead development and execution of phase-appropriate, risk-based biological evaluation strategies for new and existing medical devices, combination products, components, materials, manufacturing changes, and product modifications. Author and critically review Biological Evaluation Plans and Biological Evaluation Reports that integrate device categorization, nature and duration of contact, chemical characterization, toxicological risk assessment, existing data, and biological testing. Apply ISO 10993 principles, including ISO 10993-1, to determine relevant biological endpoints and establish scientifically justified testing, read-across, bridging, or testing-waiver strategies. Integrate device extractables and leachables data, chemical and material characterizations, and exposure information with toxicological hazard data to assess patient risk and support product safety conclusions. Develop toxicological risk assessments for identified constituents and establish health-based exposure limits using relevant toxicology principles, weight-of-evidence methods, and computational toxicology tools. Serve as the medical device toxicology and biocompatibility subject matter expert on product development, lifecycle management, remediation, and regulatory-response teams. Critically evaluate complex or conflicting data, identify evidence gaps and product-safety risks, and recommend pragmatic, science-based paths forward that balance patient safety, regulatory expectations, program timing, and business needs. Lead biocompatibility workstreams and integrated project plans, including scope, milestones, dependencies, timelines, budgets, risks, and decision points. Contribute to global regulatory submissions and responses by authoring, reviewing, and defending medical device toxicology and biocompatibility content.
