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.
We are hiring an IT Architect to define and drive cloud-native integration architecture across Ontada products 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 integration 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 as Ontada expands intelligent experiences, but is not the core requirement.
TECHNICAL ENVIRONMENT
Cloud-Native Integration: API-led connectivity, event-driven architecture, pub/sub, schema management, idempotency, retries, backpressure
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
KEY RESPONSIBILITIES
Architecture Leadership & Strategy
- 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.
Cloud-Native Integration Architecture
- 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).
Healthcare Interoperability (Optional) & Partner Integrations
- 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.
Operational Excellence & Production Ownership
- 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.
AI Enablement (Preferred)
- Partner with product and engineering teams to identify and deliver AI-enabled capabilities, from discovery and design through deployment, monitoring, and continuous improvement.
- Guide architecture patterns for integrating model services into cloud-native systems (APIs, events, data pipelines) with appropriate security, privacy, and compliance controls.
- Promote MLOps/LLMOps practices (versioning, CI/CD, automated testing, observability, rollback) and responsible AI governance.
- Collaborate on evaluation approaches to ensure AI features are reliable and safe for production use.
MINIMUM REQUIREMENT
Degree or equivalent and typically requires 7+ years of relevant experience.
Education

Get Access To All JobsTips for Finding Senior IT Architect Jobs
Lead with enterprise-scale credentials
Sponsors for Senior IT Architect roles want evidence of system design at scale. Highlight cloud migrations, infrastructure overhauls, or multi-platform integrations you led. Tangible scope signals to employers that the role clears the specialty occupation bar.
Confirm your degree aligns with the role
USCIS requires your degree field to match the position. A computer science, information systems, or software engineering degree maps cleanly. An unrelated bachelor's can create RFE risk, so address any field mismatch in your sponsorship conversation early.
Target employers with an active H-1B filing history
Large technology firms, financial institutions, and consulting groups file hundreds of H-1B petitions annually. Prioritize companies with a documented sponsorship track record rather than first-time sponsors, who face steeper compliance learning curves and longer timelines.
Quantify your architecture impact in applications
Generic resumes stall sponsorship decisions. Frame your work in measurable outcomes: systems supported, uptime improvements, cost reductions from infrastructure decisions. Sponsors use this detail to justify specialty occupation status in the petition documentation.
Understand the H-1B lottery timeline before negotiating
Cap-subject H-1B petitions are filed in April for an October start date. If you're mid-process, ask whether the employer qualifies for cap-exempt filings through a nonprofit or university affiliation, which bypasses the lottery entirely.
Get clarity on the LCA before signing anything
Your employer must file a Labor Condition Application with the Department of Labor before your petition is submitted. Confirm they've done this before you resign from a current role. A missing or delayed LCA is the most common avoidable bottleneck.
Frequently Asked Questions
Does a Senior IT Architect role qualify as a specialty occupation for H-1B purposes?
Yes, in most cases. Senior IT Architect positions typically require a bachelor's degree or higher in computer science, information systems, or a related engineering field, which satisfies the specialty occupation definition. The key risk is if the job description is written broadly enough that any bachelor's degree qualifies, regardless of field. Employers should draft the role narrowly and specifically to reduce RFE exposure.
What visa types are realistically available for Senior IT Architects seeking sponsorship?
H-1B visa is the most common path, but Senior IT Architects with a strong publication record, patents, industry awards, or conference speaking history may qualify for the O-1A, which has no lottery and no annual cap. Candidates already working for a multinational may also explore the L-1A or L-1B if transferring from an overseas office. Each path has different documentation requirements and timelines.
How competitive is H-1B sponsorship for IT Architect roles compared to other tech positions?
IT architecture roles are among the stronger sponsorship bets in tech because they require a specific, advanced skill set that's harder to fill domestically. Employers sponsoring architects tend to be larger organizations with dedicated immigration counsel, which means the petition quality is generally higher. That said, the H-1B lottery is still random, so cap-exempt employers and O-1A eligibility are worth evaluating in parallel.
Where can I find Senior IT Architect jobs that explicitly offer visa sponsorship?
Migrate Mate filters specifically for roles open to visa sponsorship, which removes the guesswork of cold-applying to employers who won't sponsor. Senior IT Architect listings on Migrate Mate are sourced from companies with established immigration programs, so you're not wasting applications on employers who treat sponsorship as an afterthought.
Can work experience substitute for a degree when applying for sponsored Senior IT Architect roles?
USCIS allows three years of specialized work experience to substitute for one year of a bachelor's degree under certain conditions, so a candidate without a four-year degree would need roughly 12 years of directly relevant experience to qualify. In practice, most sponsors for Senior IT Architect roles require at minimum a bachelor's degree because it simplifies the specialty occupation argument. Experience alone is a harder case to make and increases RFE risk significantly.
What is the prevailing wage requirement for sponsored Senior IT Architect jobs?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
