About the Role :

We are looking for a Backend Engineer to design, build, and maintain entitlement

- Develop backend services and APIs (Java Spring Boot, Python, or Go).

- Implement entitlement server logic for silent authentication (EAP-AKA, fallback).

- Build microservices, containerized deployments (Docker, Kubernetes, Helm).

- Maintain CI/CD pipelines (GitHub Actions, GitLab, Jenkins).

- Implement logging, monitoring, and observability (Prometheus, Grafana, ELK).

- Collaborate with QA for automated test suites (unit + integration, >70% coverage).

- Work with integration engineers to expose APIs for HSS, AAA, UDM, PCRF.

- Ensure security-first development : input validation, encryption, token flows.

What We're Looking For :

- Strong backend development experience (Java, Go, or Python).

- Solid understanding of REST/GraphQL APIs, microservices, and API gateways.

- Familiarity with containerization (Docker/K8s) and cloud deployment practices.

- Good knowledge of authentication/authorization flows (OAuth2, OpenID, or telecom-
specific EAP-AKA preferred).

- Exposure to telecom or networking systems is a plus.
