Role
Summary
Ontadais an oncology data science and technology business dedicated to transforming the fight against cancer. We specialize in real-world data and evidence generation that accelerates life science research, clinical technologies that support community providers with precise care, and provider engagement channels that enable education and
insights.
We are hiring anIT Architect to define and drive cloud-native integration architecture acrossOntadaproducts and partner ecosystems. This role owns solution and platform architecture for API-led connectivity, event-driven integration, and secure data exchange-ensuring our systems are scalable, reliable, observable, and straightforward to evolve. Familiarity with healthcare interoperability standards (HL7/FHIR, including SMART on FHIR) is a plus for certain partner pathways, but the primary focus is strong enterprise-architecture fundamentals applied to modern cloud-native integrati
on models.
Success in this role is measured by the clarity and adoption of your reference architectures and standards, the reliability and scalability of the integration ecosystem you enable, and your ability to influence decisions across multiple initiatives while mentoring and elevating engineering teams. Familiarity with AI/ML and NLP capabilities used in products (e.g., LLM-enabled workflows, retrieval patterns, evaluation, and governance) is a plus asOntadaexpands intelligentexperiences, butis not the core
requirement.
