Overview
You will join Automation development team to build and evolve an in-house platform that runs large-scale load and functional tests for real-time communication and VoIP systems. You will own features end-to-end, work across the stack — from Java services down to C/C++ media components and Linux networking — and help scale tests that simulate thousands of concurrent users and calls.
We expect strong fundamentals, leadership capability and the ability to learn fast: several of our specialized tools and technologies are developed in-house, and you will have room to grow into them on the job.
Responsibilities
•Design, build, and maintain Java components of the test-automation platform.
•Work with real-time media and VoIP flows: signaling, media transport, NAT traversal, and transport security.
•Build and debug C/C++ components on Linux when needed.
•Package and run the system with Docker and container orchestration.
•Diagnose complex issues across application code, protocols, containers, and networking.
•Contribute to CI/CD, code review, and technical documentation.
•Collaborate daily in English with a distributed, international team.
Requirements
•4+ years of software development, with strong senior-level Java (concurrency, multithreading, performance).
•C/C++: able to read, build, and debug native code on Linux.
•Docker and containers; comfortable running multi-service systems.
•Linux: shell scripting, service management, troubleshooting.
•Networking fundamentals: TCP/UDP, TLS, sockets, NAT, and packet inspection.
•Advanced English, written and spoken.
