Key facts

What you'll do

• Design and implement unit and characterization tests to ensure that the migrated business logic aligns with the standards set by the legacy system.
• Develop and sustain automation frameworks while managing user acceptance testing (UAT) and DevOps activities.
• Integrate deliverables into continuous integration and continuous deployment (CI/CD) pipelines, establishing stringent quality gates to guarantee a perfect match with the golden master.
• Ensure that performance regressions remain below 10 percent compared to the original C++ baseline.
• Create a comprehensive test suite that encompasses at least 3,200 test cases, achieving a minimum of 80 percent code path coverage for critical components such as Node Managers, Event Handlers, and the BRG Module.
• Conduct performance profiling to validate that throughput remains between 7,000 to 8,000 transactions per second (TPS) and that event processing latency is kept under 5 milliseconds.
• Validate inter-process communication (IPC) behavior, cache operations including L1/L2 Redis tiering, and the state transitions of Node Managers.
• Collaborate with cross-functional teams to identify and resolve quality issues throughout the development lifecycle.
• Mentor junior engineers in best practices for testing and automation, fostering a culture of quality within the team.
• Stay updated with industry trends and emerging technologies to continuously improve testing strategies and methodologies.

• Familiarity with Golden Master Testing and the development of characterization tests.
• Experience with AI-assisted test generation techniques and performance profiling methodologies.
• Understanding of telecom protocols such as SS7 and Diameter.
• Proven ability to integrate automation processes into CI/CD pipelines, specifically using tools like Jenkins.
• Excellent debugging skills, including the ability to analyze logs and recognize patterns.
• Proficient in English, with experience using project management tools such as JIRA, Notion, and version control systems like Git.
• Experience with Ansible and various CI/CD automation tools is highly desirable.

Nice to have

• Familiarity with AI-driven software development lifecycle (SDLC) tools, such as Claude Code.
• Experience in cloud-native testing, chaos engineering practices, and implementing Kubernetes health probes.
• Knowledge of observability tools and stacks, including Prometheus, OpenTelemetry, Grafana, and ClickHouse.
• Background in testing distributed data consistency, cross-site Redis replication, and conflict resolution strategies.
• Experience with message bus testing, particularly in relation to Kafka partitioning and legacy Spread IPC systems.
