Senior SDET — Enablement Platform
About Swap
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 SDET to join our Enablement Group. Enablement builds the shared foundations that power all teams: internal developer tooling and core services, reusable UI platform components, CI/CD and operational enablement, access/security integrations, public APIs and platform adapters, and Apollo (Swap’s ingestion + event/webhook intake and distribution layer).
This role owns quality standards for internal systems and drives adoption and compliance across teams. You will define functional and non-functional quality requirements, translate them into measurable standards, and ensure internal services meet them through reviews, gates, validation, and operational signals.
Responsibilities
Lead definition of quality standards for internal systems (functional and non-functional): reliability, performance, scalability, security, availability, observability, data correctness, and operability.
Partner with engineering teams to turn standards into service-level requirements and clear acceptance criteria for platform capabilities and internal services.
Own the compliance loop: define how compliance is measured, introduce evidence (tests, checks, dashboards), and drive remediation when gaps are found.
Run structured quality reviews for internal services: design reviews, readiness reviews, release criteria, and post-incident follow-ups that update standards and checks.
Define and maintain quality gates in CI/CD that enforce standards without slowing teams down (contract checks, smoke/regression, security checks where relevant).
Establish API quality standards for public APIs and platform adapters: contracts, backward compatibility, versioning, integration requirements.
Lead cross-team alignment: document standards, drive adoption, coach teams, and create lightweight processes that teams follow.
Requirements
5+ years in quality engineering / QA / SDET / reliability-oriented roles in a distributed systems environment.
Strong ability to define engineering standards and get teams to adopt them through influence and clear workflows.
Solid understanding of non-functional requirements: reliability, performance, scalability, security, observability, and operational readiness.
Strong technical background: able to review designs, understand system behavior and failure modes, and speak fluently with engineers.
Experience with CI/CD and quality gates; ability to translate standards into automated checks and measurable signals.
Experience testing and validating APIs (contract testing, integration testing, backward compatibility).
Strong ownership and organisation: can coordinate across multiple teams and drive compliance over time.
