Your responsibilities

• Own solution architecture for Java services across authoring, governance, transformation, packaging, and delivery
• Define service boundaries and contracts for Studio and Mosaic, including assembler, resolver, LMS integration, content delivery, identity, and progress / learning-record services
• Design a canonical content model for modular lessons, topics, assessments, and media, and keep it stable across Java APIs and React experiences
• Define taxonomy and ontology services exposed through APIs so classification stays consistent across authoring, search, and delivery
• Architect workflows for approvals, versioning, quality gates, lineage, and audit trails
• Design standards-based transformation and packaging across XML, JSON, BITS, QTI, XLIFF, SCORM, xAPI, LTI, PDF, and ePub
• Lead integration architecture across the component CMS, taxonomy, translation management, search, publishing, and learner channels (including Canvas and Brightspace)
• Define AI-assisted drafting, tagging, enrichment, semantic search, and recommendation patterns, including how Java services call and govern those capabilities
• Establish human review checkpoints, attribution, prompt and model versioning, and traceability of AI-generated content
• Design identity and entitlement integration: Entra ID workforce SSO, Kong as the backend-for-frontend, JWT validation in Java services, LTI 1.3 learner federation, roles, paywalls, and secure access to published content
• Shape AWS runtime architecture for these services: Aurora PostgreSQL, S3 and CloudFront delivery, secrets, and container deployment
• Ensure end-to-end observability across authoring, classification, approval, transformation, delivery, and AI actions (OpenTelemetry, metrics, and correlated logs)
• Set engineering standards for OpenAPI, persistence (JPA and schema migrations), error semantics, and testability of the Java services

Our requirements

• 8+ years in solution, content, information, or enterprise architecture, with a substantial record of shipping Java services
• Production experience with modern Java service frameworks (Micronaut or Spring), Gradle or Maven, REST, and OpenAPI
• Experience with structured component CMS platforms and component-level content models
• Experience with taxonomy and ontology platforms exposed through APIs
• Experience with translation workflows, translation memory, glossaries, and XLIFF exchange
• Knowledge of search and discovery architecture, including semantic search and recommendations
• Experience with publishing and transformation pipelines
• Familiarity with learning delivery standards and channels such as LTI 1.3, SCORM, xAPI, Canvas, and Brightspace
• Experience with API, event, workflow, and file-ingest architectures
• Strong cloud architecture experience on AWS (relational data, object storage, CDN, secrets, container platforms)
• Experience with gateway and session architecture, identity integration (OIDC/JWT, SSO, federation), and secure access patterns
• Familiarity with application stacks such as React front ends consuming Java services
• Experience integrating structured editors such as CKEditor with content models

Optional

• Experience with logical architecture across presentation, capability, content, integration, and infrastructure layers
• Hands-on Micronaut, Flyway, and PostgreSQL / Aurora
• Experience with Kong (or a similar API gateway) as a backend-for-frontend in front of Java APIs
• Experience migrating legacy long-form content into modular reusable components
• Familiarity with xAPI learning-record stores and content analytics
• Knowledge of semantic standards such as SKOS or RDF
• Knowledge of content standards such as BITS and QTI
• Experience governing a canonical model across multiple vendor platforms
• Experience with OpenTelemetry and Prometheus-style metrics on JVM services
