You will work closely with our Director of Innovation, data architecture team, and front-end developer to design and build backend services, APIs, and data-centric applications that support critical workflows—such as licensing, compliance, digital pathology, and internal automation.

Collaboration & Mentorship <ul> <li class="MsoNoSpacing">Partner closely with a junior front-end developer to ensure clean, well-documented backend interfaces that support high-quality user experiences.</li> <li class="MsoNoSpacing">Provide technical mentorship across the Innovation team, sharing patterns, code reviews, and guidance on design and implementation.</li> <li
