Job purpose: We are seeking a Backend Software Engineer to design, build, and maintain scalable
backend systems and APIs that support multiple internal and customer-facing platforms.

This role focuses on backend architecture, system integration, and API-driven platforms. The successful

similar frameworks).
Build and maintain TMF-aligned REST APIs for service ordering, product catalogue,
feasibility, provisioning, monitoring, and ticketing.
Integrate backend services with internal and external systems, including OSS/BSS
platforms, ServiceNow, and third-party APIs.
Collaborate with frontend developers to define API contracts, data models, and response
structures that support user-facing applications.
Implement authentication and authorization mechanisms such as OAuth2, SSO, and serviceto-
service authentication.
Design and maintain backend data models and persistence layers (PostgreSQL/MySQL).
Implement robust error handling, logging, monitoring, and observability for backend
services.
Write and maintain technical documentation for APIs, integrations, and backend workflows.
Perform ongoing maintenance, debugging, and performance optimization of backend
systems.
Work closely with system architects, integration engineers, and business stakeholders to
refine requirements and ensure alignment with enterprise standards.
