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, includingchaos engineering tests and validating the behavior ofKubernetes 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-siteRedis replication andconflict resolution (LWW).

  • Familiarity with message bus testing, specificallyKafka partitioning and legacySpread IPC for message fidelity and ordering validation.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
