Senior IT Architect; Enterprise​/Clinical Platforms

Role Summary

Ontada is 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.

• Cloud‑Native Integration: API‑led connectivity, event‑driven architecture, pub/sub, schema management, idempotency, retries, back pressure
• APIs: RESTful services, OpenAPI/Swagger, API gateways, versioning and contract‑first design
• Messaging:
  Kafka (or equivalent), queues/streams, event schema design
• Platform Patterns:
  Microservices, containerization (Docker), service discovery, configuration management; service mesh (where applicable)
• Data & Performance:
  Oracle and relational databases;
  Redis (caching);
  Elasticsearch; analytics/pipelines (e.g., Databricks)
• Interoperability (nice to have): HL7v2, FHIR (R4+), SMART on FHIR, OAuth2/OIDC, C‑CDA
• Observability:
  Logging, metrics, distributed tracing (e.g., Dynatrace)
• Cloud & Platforms:
  Azure, AWS, GCP, Cloud Foundry
• Engineering Practices: CI/CD, automated testing, code reviews, architecture documentation

• Drive architecture for interoperability and integration capabilities across systems, services, and product offerings.
• Partner with Product Owners, Sales, Business Analysts, Quality Assurance, and Project Management to translate functional and non‑functional requirements into target architectures and delivery plans.
• Define architecture standards, reference implementations, and guardrails for APIs, integration patterns, security, and operational readiness.
• Evaluate solution options and drive alignment across stakeholders; communicate tradeoffs, risks, and recommendations to technical and non‑technical audiences.
• Provide technical guidance to coach, motivate, and develop engineers and architects.

• Define and govern integration reference architectures across APIs, events, and asynchronous workflows (request/response, pub/sub, choreography vs. orchestration).
• Establish platform patterns and guardrails for API gateways, service‑to‑service communication, schema/version management, and contract testing.
• Design for resiliency and performance using proven patterns (timeouts, retries, circuit breakers, bulkheads, idempotency, caching) and align to SLOs/SLAs.
• Guide event‑driven integration (e.g., Kafka or equivalent) with well‑defined event schemas, lifecycle management, and operational controls.
• Collaborate with security and platform teams to ensure secure‑by‑default integration approaches (OAuth2/OIDC, least privilege, secrets management, threat modeling).

• When applicable, drive design for healthcare data exchange leveraging HL7v2 and/or FHIR (R4+), including SMART on FHIR, to enable integrations with EMRs and partner systems.
• Partner with domain SMEs and external stakeholders to define interoperability expectations (security, conformance, and onboarding) and ensure integrations are scalable and supportable.
• Define API contracts, versioning strategy, and error taxonomy to enable predictable integrations for internal and external consumers.
• Partner with engineering teams to implement and evolve reusable integration components, adapters, and accelerators that reduce time‑to‑integrate.

• Collaborate with engineering in release, sprint, and project planning to ensure delivery commitments are tracked and met across the SDLC.
• Demonstrate strong architectural ownership in production operations to address customer needs for support, issue analysis, enhancements, and corrective actions.
• Evolve software systems, infrastructure, and architecture to support growth, SLAs, availability, and continued operation.
• Drive operational readiness practices including observability, runbooks, incident response, and post‑incident improvements.
• Resolve technical problems, issues, and escalations across delivery teams and project activities.
