Job Description
Role Overview We are looking for a System Test Automation Engineer who is a software engineer at heart, with strong systems knowledge, sharp analytical thinking, and a passion for building scalable, automated quality frameworks. This role focuses on validating complex, distributed software systems through automation, observability, and system‑level testing rather than manual or UI‑centric testing. You will analyze system behavior, reason about failure modes, and derive clear conclusions even when working with incomplete, ambiguous, or noisy data. You will work closely with development, architecture, and platform teams to embed quality early in the lifecycle, design robust test frameworks, apply data‑driven quality insights, and prevent defects from reaching customers.
Key Responsibilities
Test Automation & Frameworks • Design, develop, and maintain system‑level test automation frameworks for complex software platforms. • Integrate automated tests into CI/CD pipelines to enable continuous validation. • Own test infrastructure, frameworks, and tooling — not just individual test cases. System‑Level Validation • Build and execute regression, scale, stress, soak, and fault‑injection tests. • Validate system behavior under real‑world conditions including high load, failures, and degraded states. • Identify issues related to timing, concurrency, memory leaks, performance, and resource exhaustion. Observability, Analysis & Debugging • Leverage and enhance observability signals (logs, metrics, traces, counters). • Apply analytical and logical reasoning to break down complex behaviors and isolate root causes. • Use data‑driven analysis to detect regressions, identify trends, and surface systemic quality risks. • Diagnose failures by clearly distinguishing test issues vs product defects. • Work with developers to add testability hooks, diagnostics, and observability into the product. Early Quality Engagement • Participate in design and architecture reviews with a strong testability and quality mindset. • Influence design choices to enable deterministic, scalable, and measurable testing. • Shift defect detection earlier in the development lifecycle through proactive quality engineering. Collaboration & Ownership • Partner closely with development, release, and operations teams. • Influence engineering decisions using clear data, analysis, and technical communication. • Take end‑to‑end ownership of system quality for assigned features or platforms.
Required Qualifications
Education and Experienced Required: Typically 8-10 years of work experience in Test Engineering Bachelor's degree Technical Skills • Strong programming skills in Python, Go, or C++ (at least one at production depth). • Proven experience building automation frameworks, not just test scripts. • Solid understanding of Linux/UNIX fundamentals (processes, memory, networking). • Familiarity with CI/CD systems and version control (Git‑based workflows). • Experience testing complex, multi‑component,
