Client
Our client is assembling a team to develop and upgrade systems for an international association of financial industry professionals. The organization unites 200,000 investment experts and operates more than 100 different applications to support its global operations.
Position overview
We are looking for a Solution Architect to own the solution architecture of Java services across Studio and Mosaic. The architect sets service boundaries, API and event contracts, persistence, identity, and integration patterns for authoring, governance, transformation, packaging, and delivery and stays close enough to the code to make those designs real in Micronaut services.
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
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
Nice to have
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
