Objective
Engage a contract Data Engineer / Backend API Engineer to design and implement internal backend APIs supporting an enterprise data integration platform. These internal APIs will orchestrate processing, validate data, and route requests to downstream systems, operating behind an externally exposed API layer.

Scope of Work

Design and build internal REST and event‑driven APIs that receive single requests from an external API layer for downstream processing

Implement backend logic to:

Validate, transform, and enrich incoming data

Orchestrate workflow and route requests to target systems and databases

Route each request to the appropriate destination system

Integrate backend services with:

Internal databases

Downstream systems and APIs

Ensure solutions meet agreed non‑functional requirements for:

Reliability, scalability, and performance

Logging, monitoring, and error handling

Secure data handling and interface contracts

Collaborate with internal application, platform,



and integration teams to ensure alignment on API contracts, event schemas, and deployment timelines

Produce technical documentation sufficient for operational support and knowledge transfer

Technical Setting

Cloud Platform: Azure (primary), AWS (secondary if required)

API Styles: REST APIs and event‑driven messaging

Core Technologies:

Java or .NET for backend API implementation

Kafka for event streaming and asynchronous processing

Integration: Internal systems, databases, and downstream APIs

Engagement Model

Minimal discovery; work executed against a defined architecture and scope

Contractor expected to work independently while coordinating with internal teams as needed

Production‑ready internal backend APIs and supporting data pipelines

Event‑driven integration components where required

Technical documentation and handoff materials

Duration & Resourcing
Specific duration, capacity, and milestones to be defined within the commercial SOW.
