Job description

Swap is the infrastructure behind modern agentic commerce. The only AI-native platform connecting backend operations with a forward-thinking storefront experience.

Built for brands that want to sell anything - anywhere, Swap centralises global operations, powers intelligent workflows, and unlocks margin-protecting decisions with real-time data and capability. Our products span cross-border, tax, returns, demand planning, and our next-generation agentic storefront, giving merchants full transparency and the ability to act with confidence.

At Swap, we’re building a culture that values clarity, creativity, and shared ownership as we redefine how global commerce works.

About the role

We 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.

Responsibilities

• 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.

Requirements

• 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.
• Stock options in a high-growth startup.
• Competitive PTO with public holidays additional.
• Private Health.
• Pension.
• Wellness benefits.
• Breakfast Mondays.
