Preferred Qualifications * Experience with identity, authentication, authorization, PKI, cryptography, zero-trust systems, or verifiable evidence. * Experience with containers, Kubernetes, infrastructure as code, service virtualization, or fault-injection testing. * Experience with Chaos Monkey or equivalent fault-injection tooling to test SaaS service robustness and recovery under simulated infrastructure failures. * Familiarity with agentic AI, MCP, LLM integrations, or testing workflows with nondeterministic outcomes. * Experience testing regulated or security-sensitive products and maintaining traceable test evidence for assurance reviews. ## Description This Senior Quality Engineering role independently designs, builds, and maintains automated tests for significant capabilities within the Entrust Agentic Trust SaaS platform. The role owns feature- and service-level quality across the development lifecycle, with a strong focus on automation, robustness, performance, and scalability in distributed, multi-tenant environments. Working with Software Development, Product, Architecture, Security, and Cloud Operations, this role translates requirements and technical designs into risk-based test strategies and reliable automated coverage. The role understands how assigned services connect to the Identity, Authority, Execution, and Assurance planes, identifies defects early, and provides evidence-based recommendations on release readiness while mentoring less experienced engineers. Key Responsibilities * Own test planning and quality execution for complex features and services, including acceptance criteria, risk assessment, test design, automation, and release verification. * Develop and maintain code-based API, integration, contract, end-to-end, and regression automation; contribute reusable utilities and framework improvements aligned with shared standards. * Integrate automated suites into CI/CD pipelines, investigate failures promptly, and improve test stability, execution efficiency, and diagnostic output. * Design and execute load, stress, spike, and soak tests using representative SaaS workloads; analyze latency, throughput, errors, and resource utilization to identify scalability limits. * Validate robustness under concurrency, retries, timeouts, dependency failures, interrupted workflows, and recovery scenarios; verify data consistency and resilience against agreed requirements. * Test tenant isolation, role and permission boundaries, authentication, delegated authorization, and evidence integrity in partnership with Security and Software Development. * Create and maintain production-representative environments and synthetic or approved de-identified test data; validate service integrations, upgrades, migrations, and backward compatibility. * Investigate defects and production issues using logs, traces, metrics, and controlled reproduction; collaborate on root-cause analysis and regression prevention. * Communicate coverage gaps, defects, performance findings, and residual risks to stakeholders; provide clear service-level release-readiness recommendations. * Participate in design and code reviews, mentor engineers in automation and test design, and contribute to shared quality engineering practices.
