About the roleWe are looking for a Senior QA Engineer / SDET to work with product, engineering, and our Agentic AI team building an agentic storefront and new e-commerce workflows. You will lead quality across a complex system, define the QA strategy and operating model from scratch, and build the tooling, processes, and automation needed to ship reliably.
- Own QA strategy and execution for agentic AI and core ecommerce flows (definition of done, quality gates, release readiness).
- Define and roll out QA processes from scratch: test planning, risk assessment, defect triage, reporting, and continuous improvement.
- Lead cross-team alignment on quality standards and drive adoption through coaching and clear workflows.
- Design test architecture across unit/integration/contract/E2E, with a focus on reliability, maintainability, and signal quality.
- Build and maintain automation and CI/CD integration; reduce flakiness and improve time-to-signal.
- Define AI-specific validation for agent workflows: tool-calling paths, multi-step journeys, failure handling, regressions, and guardrails.
- Partner on system design to identify bottlenecks and failure modes; propose changes that improve testability, observability, and resilience.
- 5+ years in QA / quality engineering for modern web products (APIs + UI).
- Strong coding skills and hands-on automation experience (language flexible; Python/TypeScript common).
- Proven track record of building QA processes and test strategy from scratch in a fast-moving environment.
- Strong leadership and ownership: can organize work across teams, set direction, and drive execution without formal authority.
- Solid CI/CD experience: test automation in pipelines, quality gates, environment strategy, and test data management.
- Strong engineering mindset and system design skills; able to reason about distributed systems and propose pragmatic improvements.
