Lead the creation and management of Unit & Characterization tests (Golden Master generation) to validate the ported C++ business logic against legacy behavior.
Implement and maintain test automation, Quality Assurance, and coordinate UAT and DevOps activities.
Integrate workflow and deliverables into the existing CI/CD pipelines, enforcing strict Quality Gates, ensuring 100% golden master match and constraining performance regression to less than 10% from the C++ baseline.
Drive the creation of a comprehensive test suite targeting ≥3,200 total test cases and ≥80% code path coverage across core components like Node Managers, Event Handlers, Business Rules, and the BRG Module.
Conduct performance profiling and testing to meet Non-Functional Requirements (NFRs) like 7,000–8,000 TPS throughput and event processing latency of <5ms.
Focus on validating key modernization aspects, including IPC behavior, cache operations (L1/L2 Redis tiering), and Node Manager state transitions.

Minimum of 6 years of progressive experience in the IT field, demonstrating comprehensive knowledge of testing strategies, methodologies, and automation in complex software development environments.
Mandatory Experience: Automated testing for both Java and C++ codebases.
Technical Stack: Strong proficiency in Java (targeting Java 21) and experience with high-availability/high-performance (HA/HP) systems.
Testing Methodology: Deep experience with Golden Master Testing and characterization test creation.
AI/Automation Skills: Proven ability to implement AI-assisted test generation & automation, including performance profiling/testing.
Domain Knowledge: Ability to quickly understand and validate telecom-specific protocols (SS7 and Diameter) that interact with the modernized application logic.
CI/CD: Experience in integrating test automation into CI/CD pipelines (e.g., Jenkins) and establishing performance baselines.
Solid debugging skills and experience (e.g., analyzing log files, spotting patterns).
Experience with tools for tracking and documenting development processes (JIRA, Notion, git) is an advantage.
Working with automation tools (Ansible, Jenkins, CI/CD).
Good communicator & fluent in written and spoken English.
