Madrid, Spain

What you'll do

Quality strategy & ownership

  • Define, implement, and continuously improve testing strategies in close alignment with the product and engineering teams.
  • Serve as the team's subject matter expert on QA processes, tooling, and best practices — raising the bar for the whole squad.
  • Maintain clear, accurate, and actionable test documentation and reporting for both developers and business stakeholders.

Hands-on testing

  • Test newly implemented features using a diverse range of testing techniques, with a focus on uncovering gaps early.
  • Perform exploratory testing to proactively identify regressions and edge cases before they reach production.
  • Provide fast, reliable feedback on product health and stability to developers and stakeholders throughout each sprint.

Automation & tooling

  • Develop, execute, and maintain automated test suites covering E2E and API testing for both web and mobile applications.
  • Perform root cause analysis on failing automated tests and drive their resolution.
  • Set up and maintain CI/CD pipelines to ensure continuous quality gates are in place (Azure DevOps preferred).
  • Contribute to AI-assisted development efforts and explore how emerging tooling can improve the team's quality workflows.

Collaboration & communication

  • Report bugs clearly and follow up on their resolution, monitoring the bug backlog to keep it actionable.
  • Support developers in investigating and reproducing issues, acting as a trusted partner rather than a gatekeeper.

Your Responsibilities

  • Test the products applying diverse testing techniques to uncover bugs.
  • Report bugs and follow up their resolution.
  • Develop new and maintain the existing automated end-to-end and API tests.
  • Contribute in the AI assisted development efforts and tooling.
  • Setup and maintain CI/CD pipelines.
  • Perform root cause analysis of failing automated tests.
  • Provide the developers and business representatives with fast feedback regarding the current state of the product.
  • Assist and help the developers in investigating issues.

Your Experience

What you bring

Must-haves

  • 6+ years of experience testing web-based applications.
  • 4+ years of experience in test automation using JavaScript or TypeScript — ideally with Playwright.
  • Solid hands-on experience in both E2E and API testing and automation.
  • Proven experience setting up and maintaining CI/CD pipelines (Azure DevOps preferred).
  • Strong root cause analysis skills and the ability to diagnose flaky or failing tests independently.
  • Excellent written and spoken English.

How you work

  • Autonomous and accountable — you take ownership of your work and deliver it with care.
  • A proactive team player who communicates clearly and keeps stakeholders in the loop.
  • Critical thinker who questions assumptions and advocates for the right level of quality.

Nice to have

  • Exposure to AI-assisted development tools and workflows.
  • Experience testing mobile applications (native or hybrid).
  • Familiarity with the enterprise SaaS or supply chain compliance domain.
