Tasks and Deliverables. Lead, design, and build end-to-end quality for Event-Driven Architecture (EDA), low-latency platform built on Solace messaging, and Azure (AKS). You will own the test strategy, plan, automation framework, CI/CD pipelines, and compliance testing. The role is hands-on and leadership-oriented: you will set standards, coach engineers, and deliver audit-ready evidence for regulated markets.. Responsibilities. Own test automation strategy & governance. Define a shift-left test strategy across unit, integration, contract, E2E, performance, security, and resiliency.. Establish quality gates (defects, coverage, flakiness budgets, performance SLOs) and release criteria.. Shift left testing: requirements → tests → results → evidence traceability model.. Build a reusable automation framework. Architect a test framework packaged for reuse across CEE teams.. Provide libraries/utilities for API, Solace messaging, database, and contract testing.. Standardize test data management, deterministic fixtures, and parallel/ephemeral execution patterns.. Event-driven architecture (EDA) testing. Validate producer/consumer contracts, schema evolution, and topic compatibility.. Assert ordering, idempotency, exactly/at-least/at-most-once semantics, replay, DLQ handling, and deduplicate keys.. Prove back-pressure, throttling, and consumer lag behavior under bursty market loads; chaos test broker clusters.. Enforce schema/contract gates in CI/CD; prevent breaking changes before promote.. Data-platform & reconciliation QA. Automate data quality checks for market/reference data, order/trade states, and downstream stores (SQL Server/Azure SQL).. Implement reconciliation across OMS/EMS, risk, and settlement; verify lineage and PII/PCI masking where relevant.. Use SQL and profiling to validate accuracy, completeness, timeliness, and SCD/versioned data behaviors.. Manage golden datasets and synthetic market data at scale for repeatable regression.. Pipelines, environments & observability. Embed suites in Azure DevOps (build → deploy → smoke → regression → perf/security) with mandatory gates (coverage, static analysis, compliance, performance).. Orchestrate tests on AKS with Docker/Kubernetes, ephemeral environments.. Validate OpenTelemetry to correlate trace IDs across services; validate Application Insights/Dynatrace signals in assertions.. Performance & security. Baseline latency/throughput; run JMeter/LoadRunner for spike/soak/failover; collaborate on capacity tuning.. Automate OWASP checks (ZAP), enforce SAST/DAST and dependency scanning (Snyk) with remediation gating.. Leadership & operations. Lead QA activities in the project, mentor developers on testability and quality by design.. Contribute to incident response, RCA, production canary/verification suites, and reliability playbooks..
