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

- 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.
