Job Description

About the Role

Join our team working on a telecom microservices project built around SCTP and SS7 protocol stacks.

  • SCTP Service ensures reliable message transfer between peer SCTP user applications, establishing robust communication associations between endpoints.
  • SS7 Service provides SS7 stack functionality (SCCP, M3UA) over IP using SCTP, exposing SCCP connectionless API to the user. This is legacy code with minimal changes.

These services are packaged as Kubernetes Pods with their own Helm charts and integrated into a broader microservice ecosystem.

 

Key Responsibilities

  • Design and execute functional and automated tests for SCTP and SS7 components.
  • Validate deployments in Kubernetes environments.
  • Collaborate with developers to ensure quality and reliability across microservices.
  • Work in Agile sprints, using Jira and Confluence for tracking and documentation.

 

Required Skills

  • Java programming for test development.
  • Linux user-level proficiency (command line, basic scripting).
  • Git for version control.

 

Nice to Have

  • Basic networking knowledge (TCP/IP).
  • Familiarity with Kubernetes (kubectl), Docker, and Helm.
  • Experience in automated testing frameworks.
  • Jenkins for CI/CD.
  • Understanding of SS7 protocol family.
  • Python scripting.
  • TestNG framework.

 

Why Join Us?

  • Work on telecom-grade protocols in a modern microservice architecture.
  • Gain experience with Kubernetes, CI/CD, and test automation.
  • Collaborate in an international team with English as the working language.
