Requirements and responsibilities

Readable role content extracted into sections for faster review.

Key Responsibilities

  • Test Strategy & Execution: Lead the creation and management of Unit & Characterization tests (Golden Master generation) to validate the ported C++ business logic against legacy behavior.
  • Automation Focus: Implement and maintain test automation, Quality Assurance, and coordinate UAT and DevOps activities.
  • Quality Gates & CI/CD: Integrate workflow and deliverables into the existing CI/CD pipelines, enforcing strict Quality Gates. This includes ensuring 100% golden master match and constraining performance regression to less than 10% from the C++ baseline.1
  • Characterization Targets: 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.
  • Performance Engineering: Conduct performance profiling and testing to meet Non-Functional Requirements (NFRs) like 7,000–8,000 TPS throughput and event processing latency of <5ms.
  • Technical Validation: Focus on validating key modernization aspects, including IPC behavior, cache operations (L1/L2 Redis tiering), and Node Manager state transitions.

Minimum Qualifications:

  • Minimum of 5 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

Good to Have Skills

  • Familiarity with AI-led SDLC tooling used by the modernization team, such as Claude Code, to accelerate development and testing.
  • Experience with cloud-native testing methodologies, including chaos engineering tests and validating the behavior of Kubernetes health probes (readiness, liveness, startup).
  • Familiarity with the target observability stack (Prometheus, OpenTelemetry, Grafana, and ClickHouse) for validating logging, metrics, and distributed tracing.
  • Background in testing distributed data consistency, such as cross-site Redis replication and conflict resolution (LWW).
  • Familiarity with message bus testing, specifically Kafka partitioning and legacy Spread IPC for message fidelity and ordering validation.
