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.

Get Access To All JobsTips for Finding H-1B Visa Sponsorship in Senior IT Architect
Validate your specialty occupation documentation early
USCIS scrutinizes IT Architect roles for specialty occupation eligibility. Pull the O*NET profile for your SOC code and document how your degree field maps directly to enterprise architecture, infrastructure design, or systems integration, not general IT management.
Search LCA filing history by occupation code
Use Migrate Mate to filter employers who have filed LCAs under the computer systems architect SOC codes. This surfaces companies with active H-1B sponsorship history for your specific role, not just general tech employers.
Target employers with cap-exempt petition pathways
Universities, nonprofit research institutions, and government-affiliated entities can file H-1B petitions year-round outside the annual cap lottery. Senior IT Architects at these organizations skip the April registration window entirely.
Request the prevailing wage tier before negotiating
Run your job title, SOC code, and work location through the OFLC Wage Search before accepting an offer. Knowing your Level III or Level IV prevailing wage gives you a floor for salary negotiations and confirms the employer's LCA will clear DOL certification.
Clarify project-site work arrangements before the I-129 files
If your role involves client-site deployments or multi-location work, the employer must file an amended I-129 or obtain additional LCA certifications for each worksite. Confirm this scope with your employer's immigration counsel before the original petition is submitted to USCIS.
Use the 60-day grace period strategically between roles
If your H-1B employment ends, you have a 60-day grace period to secure a new offer and have a transfer petition filed. Prioritize employers who can file concurrently with the I-129 so your work authorization continues without interruption under portability rules.
H-1B Visa Senior IT Architect: Frequently Asked Questions
Does a Senior IT Architect role qualify as an H-1B specialty occupation?
Yes, Senior IT Architect qualifies as a specialty occupation when the position requires at least a bachelor's degree in computer science, information systems, software engineering, or a closely related field. USCIS evaluates each petition individually, so your employer's job description must specify the degree requirement clearly. Roles framed as general management without a specific technical degree requirement can attract a Request for Evidence.
What SOC code do employers typically use for H-1B filings for this role?
Most employers file under SOC 15-1299 (Computer Occupations, All Other) or 15-1244 (Network and Computer Systems Administrators), though enterprise architects may also fall under 15-1211 (Computer Systems Analysts). The SOC code determines the prevailing wage tier on the Labor Condition Application, so a mismatch between your actual duties and the code filed can create compliance issues. Confirm the code with your employer before the LCA is submitted to DOL.
How do I find employers actively sponsoring H-1B visas for Senior IT Architect positions?
Search Migrate Mate to identify employers with verified LCA filing history under computer systems and architecture occupation codes. This shows you which companies have sponsored this specific role type, not just general H-1B sponsors. Prioritizing employers with a documented track record in your specialty reduces the risk of navigating the process with a first-time sponsor unfamiliar with the requirements.
Can I transfer my H-1B to a new employer if I receive a better Senior IT Architect offer?
Yes, H-1B portability allows you to start working for a new employer as soon as the transfer petition is filed with USCIS, without waiting for approval. Your new employer must file a new I-129 and LCA before you begin. If your current H-1B has been approved for at least 180 days, your status is protected even if the transfer petition receives a Request for Evidence.
Does a multi-site or client-facing Senior IT Architect role create additional H-1B compliance requirements?
Yes. If your role requires regular work at client locations or multiple employer sites, your sponsoring employer must obtain a certified LCA for each worksite metropolitan area and post the LCA notice at each location. Failing to maintain site-specific LCAs is one of the most common H-1B compliance violations in consulting and professional services engagements. Clarify the worksite obligations with your employer's immigration team before your I-129 is filed.
