About The Role

We are looking for a Backend Engineer to design, build, and maintain entitlementserver modules, APIs, and automation workflows. You will work closely with telecomintegration engineers to enable seamless SIM-based authentication and entitlementflows.

Responsibilities

  • 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.
