🚀 Senior QA Automation Engineer 🚀

If you have a passion for catching issues before customers do, love writing rock-solid automated tests, and want to help elevate our product quality at Paystone, this role is for you!

As a Senior QA Automation Engineer you’ll define our automated test strategy, expand test coverage, and empower every engineer to ship confidently by building robust, comprehensive tests.

Reporting to: VP, Engineering

Department: Engineering

What You'll Be Doing:

Test Automation & Technical Leadership

  • Design, build, and maintain robust automated test suites using Jest (API / integration) and Playwright (end-to-end, cross-browser).
  • Review application architecture to identify risk areas and define the right test pyramid (unit → integration → E2E).
  • Establish and document coding standards for test automation; perform PR reviews to uphold them.
  • Investigate test failures quickly, triage defects, and collaborate with developers on root-cause analysis.

Quality Process Improvement

  • Champion shift-left testing: embed quality gates in every stage of the SDLC and CI/CD pipeline.
  • Analyze flakiness, execution time, and coverage metrics; drive continuous optimisation.
  • Introduce tooling (static analysis, mutation testing, visual regression, etc.) when it meaningfully boosts product quality.

Cross-Team Collaboration & Facilitation

  • Partner with Product Owners and Squad Leads to turn acceptance criteria into executable automated tests.
  • Act as a quality mentor: run workshops, pair-program on test patterns, and nurture a culture of ownership.
  • Review upcoming technical designs with an eye on observability and testability, providing actionable feedback early in the lifecycle.

Planning & Delivery

  • Estimate and prioritise test automation work in sprint planning, balancing risk and velocity.
  • Provide clear visibility into test coverage, defect trends, and release health to stakeholders.
  • Ensure test environments and data are version-controlled, reproducible, and aligned with production.

What We're Looking For:

  • Proven success improving product quality for SaaS solutions in an agile environment.
  • Deep hands-on expertise with Jest and Playwright (or similar frameworks) and solid TypeScript/JavaScript skills.
  • Experience integrating automated tests into cloud-based CI/CD (GitHub Actions, GitLab CI, etc.).
  • Strong understanding of testing strategies (TDD, BDD, contract testing, accessibility, performance).
  • A collaborative, solution-oriented mindset with crisp, confident communication.
  • Passion for mentorship and driving a culture of quality across engineering teams.

Whether you’re already a senior automation specialist or an experienced developer passionate about quality, this role lets you broaden your impact while staying deep in the code.

Let’s raise the bar on reliability — together. 🚀
