- Design and document a public REST API
- Build validation and transformation logic against external structured schemas
- Return clear, field level errors and remediation guidance
- Implement authentication, idempotency, durable job processing, and reconciliation, so network failures never create duplicate filings
- Preserve submission history, acknowledgements, and audit records securely
- Ensure sensitive data never appears in application logs
- Provide automated testing across units, integration, resilience, and security
- Deliver deployment, monitoring, and operational documentation
- Complete a technical handover to our engineering team
- Senior level backend engineering experience delivering production APIs
- Strong REST and OpenAPI design skills
- Experience with complex JSON data models and schema validation
- Experience integrating with token based external APIs

- Strong automated testing and documentation practices
- Java and Spring Boot experience
- Experience with bulk submission, async processing, and partial batch handling
