Data Engineer / Backend API Engineer
Cognizant Technology Solutions Corporation
**PR / Citizens who lived in Canada for more than 5 years needed due to Pro B clearance**
Location- Onsite at Toronto, ON
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 Environment
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.
