Quality Assurance Analyst

We are seeking a QA Analyst with a strong background in ecommerce testing to ensure the quality, reliability, and production-readiness of all client deliverables across Teifi Digital's Shopify Plus engagements. QA will work within a delivery pod, collaborating closely with Engineering Leads, Business Analysts, and Project Managers to define test strategies, validate acceptance criteria, and enforce quality gates from sprint execution through to go-live.

This is a hands‑on, detail-oriented role operating in a fast‑paced agency environment where projects span complex e-commerce builds, platform migrations, and custom integrations.

• Define the overall test strategy for each engagement, tailoring the approach to project scope, complexity, and risk profile.
• Create comprehensive test plans that outline testing phases, scope, timelines, entry/exit criteria, and resource requirements.
• Apply a risk‑based testing approach, prioritizing test effort toward high‑impact areas to maximize coverage within delivery timelines.
• Own test environment readiness, verifying that environments are correctly configured — feature flags enabled, settings aligned to production — coordinating with engineering to resolve infrastructure dependencies such as CI/CD pipelines and data seeding.

• Write and maintain test cases that thoroughly cover functional requirements, edge cases, and user journeys.
• Manage the test case repository, ensuring cases are versioned, organized, and reusable across projects and sprints.
• Execute QA testing across all phases of delivery, from feature-level validation through to end‑to‑end integration testing.
• Conduct sanity testing after deployments and code changes to rapidly confirm that critical functionality is intact before broader test cycles begin.
• Perform smoke testing pre- and post-deployment, validating that builds are stable enough to proceed to deeper testing or release.
• Execute regression testing to confirm that new changes have not introduced defects into existing functionality.
• Perform accessibility testing to verify compliance with accessibility standards and inclusive design requirements.
• Review design artifacts including wireframes and high fidelity mockups to identify issues early.
• Plan and execute performance testing — including page load times and basic throughput validation.

• Track and manage bugs through the full defect lifecycle, from identification through to resolution and verification.
• Triage and report defects with clear severity classification, reproduction steps, and supporting evidence to enable efficient resolution.
• Monitor and report on defect rates, establishing metrics that inform project quality assessments and drive process improvement — including defining the tooling and processes needed to capture this data systematically.
• Produce test coverage reports, providing stakeholders with visibility into what has been tested, current coverage levels, and outstanding risk.
• Maintain QA documentation and reporting, ensuring that test outcomes, known issues, and quality metrics are clearly communicated to the wider delivery team.

• Provide sprint QA sign‑off, formally confirming that all deliverables within a sprint meet the required quality bar before they progress.
• Enforce the Definition of Done, holding the team accountable to agreed quality standards and ensuring no work is marked complete without passing QA gates.
• Own and execute the go‑live QA checklist, providing a structured final quality gate before production deployment.
• Conduct post‑launch validation, verifying that the deployed solution works as expected in the production environment — accounting for environment‑specific…
