About The Position

Loyal is a clinical-stage veterinary medicine company developing longevity drugs for dogs. Our mission is to help dogs live longer, healthier lives. We're pioneering a new category of veterinary prescription drugs that proactively and preventatively target the underlying drivers of aging, delaying the onset of disease and preserving quality of life as dogs age. We've already made significant progress in our mission to develop the first FDA-approved drugs to extend canine lifespan: as of early 2026 we've completed two of three major FDA review sections for our lead program, LOY-002, and are targeting submission of the third and final section later this year. Loyal is a well-funded startup with teams of scientists, veterinarians, engineers, operators, and creatives. You'll help us continue on our path of earning FDA approval for the first lifespan extension medicine for any species, and change what's possible for the dogs we love.

The Senior Director of Clinical Development leads the team responsible for design, execution, and strategic direction of clinical programs across Loyal’s veterinary product portfolio. This role is responsible for driving end-to-end clinical strategy, from target product profile to study design and regulatory-facing protocol development through field execution, data interpretation, and evidence package generation. Experience in human clinical drug development is considered if candidates demonstrate the ability to translate human clinical rigor into the realities and constraints of veterinary medicine (owner compliance, clinic workflow, clinical trial models, and companion animal endpoints). This is a highly cross-functional role that partners closely with Veterinary Affairs, Clinical Operations, Regulatory (FDA-CVM),CMC, and Commercial to ensure our studies are scientifically sound, operationally feasible, and aligned with pathways to approval. You will be reporting to our VP, Clinical and Veterinary Medicine.

Requirements

• DVM or equivalent.
• 8–12+ years of experience in clinical development in animal health clinical development.
• Demonstrated experience designing and leading clinical trials, including protocol authorship, data review, and cross-functional collaboration.
• Prior oversight of safety evaluation, study conduct, and interpretation of clinical endpoints.
• Strong understanding of evidence requirements for regulatory approval.
• Ability to lead in a fast-paced, high-accountability biotech environment.
• Direct experience with FDA-CVM VICH guidelines.
• Experience in companion animal medicine, bonus if experience is in aging/longevity or quality-of-life endpoints.
• Background working with veterinary clinics, practice networks, or decentralized trial models.
