Senior Automation QA (JavaScript) Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Automation QA (JS) Engineer based in India.

As a Senior Automation QA Engineer, you will help establish the quality foundation for an enterprise-grade AI Agent Development Platform. You will design and own automation across frontend, backend, long-running workflows, multi-tenant infrastructure, security boundaries, and performance requirements. Because the platform relies on non-deterministic AI behavior, you will develop sophisticated testing approaches based on statistical assertions, semantic evaluation, and adversarial scenarios rather than simple expected-output checks. Your work will directly influence release readiness, client milestone sign-offs, and production reliability. You will collaborate closely with AI engineers, platform engineers, and evaluation specialists to embed quality and testability from the earliest design stages. This is a high-impact opportunity to shape reusable quality engineering practices for rapidly evolving AI-powered systems.
