Map out query patterns, access flows, and integration touchpoints with external systems (data storage and encryption services provided by partner organisations)
Collaborate with the database consulting engineer on schema design, search strategy, and encryption approach to ensure the API layer aligns with the underlying data model
Contribute to Infrastructure as Code design for deployment (Terraform or similar)

Build &amp; Implementation (Weeks 5 15, full-time)

Build a RESTful API layer in Java implementing full catalogue functionality:
CRUD operations for metadata records
Advanced search capability leveraging Atlas Search
ABAC enforcement on all API operations, ensuring search results and data retrieval are filtered by the requestor s access attributes
Secure storage and retrieval of encrypted key material (shard keys) via CS-FLE

Implement unit tests to validate functional correctness
Build automated data load and stress testing harnesses for the combined API and cluster deployment
Perform integration testing against external partner systems (or appropriate stand-ins) to validate end-to-end data creation and retrieval flows
Produce API documentation and integration guides for consuming systems
Support knowledge transfer and handover activities in the final weeks of the engagement

Essential

Java development — strong hands-on capability building production RESTful APIs (Spring Boot or similar framework)
MongoDB — solid working experience with MongoDB, including querying, aggregation pipelines, and integrating MongoDB into Java application layers
Atlas Search — practical experience designing and implementing search solutions using Atlas Search (or Lucene-based search within MongoDB)
Security &amp; encryption — experience with Client-Side Field Level Encryption (CS-FLE) or equivalent application-layer encryption patterns; understanding of key management concepts
Infrastructure as Code — experience with Terraform or equivalent for deploying and managing application infrastructure
API design — ability to design clean, well-documented RESTful APIs suitable for integration by multiple consuming systems
Testing — experience with load/stress testing tools and approaches for validating API performance under realistic conditions
Technical leadership — proven ability to make architectural decisions, produce design documentation, and communicate technical trade-offs to both engineering and non-technical stakeholders

Desirable

Experience designing and implementing Attribute-Based Access Control (ABAC) systems; familiarity with policy-as-code frameworks (e.g. Casbin, OPA, or XACML-based systems)
Experience with metadata standards such as DCAT, Dublin Core, or IES
Experience working in UK public sector or defence environments
Familiarity with multi-classification or multi-tenancy access models
Experience with event-driven architectures and asynchronous processing patterns
Understanding of consistency patterns in multi-service architectures (e.g. saga pattern, eventual consistency)
Knowledge of data mesh or federated data architecture concepts
Experience integrating with third-party data storage APIs (e.g. S3-compatible interfaces)
