Job Description:

Senior QA Engineer. We build and operate web products used daily by tens of thousands of people across 13 European countries. Treatwell Connect is our SaaS platform for salon and venue management, the tool thousands of salon owners rely on to run their business every day. Following the integration of Salonized, we now have a dedicated QA team and we're shaping it with intention. We've seen firsthand that embedded, proactive QA is what separates reliable releases from reactive firefighting. We're looking for a senior QA engineer who is passionate about quality as a team discipline: someone who builds automation foundations, runs effective exploratory testing, and shifts how the people around them think about quality, not just how they personally test.

Job Responsibility:

  • Build an automation framework from scratch, starting with API-level coverage of critical end-to-end happy path flows
  • Mentor QA team members into more technical and structured testing practice
  • Work with developers to build shared ownership of quality across engineering
  • Run exploratory testing to surface edge cases and failure modes that specs don't anticipate
  • Own feature aftercare: monitor releases in production, track stability, and drive continuous improvement
  • Identify gaps that developers and PMs miss and bring them to the table early
  • Track QA metrics that matter, bug detection rate, release confidence, post-release defect counts

Requirements:

  • 5+ years of QA experience with hands-on automation work and structured manual and exploratory testing
  • You've built automation frameworks before, not just used them
  • You're fluent in at least one programming language and can make and defend tooling decisions without a spec telling you what to choose
  • You take satisfaction from shifting how a team thinks about testing, not just from shipping test suites
  • You influence without authority
  • You can articulate risks clearly to engineers, PMs, and non-technical stakeholders
  • You want to make the people around you better

Nice to have:

  • Experience with observability and monitoring tools, particularly Datadog
  • Experience working across web, mobile, and API surfaces in a single product
  • Experience with SQL for data validation, debugging, and exploratory testing
What we offer:
  • 28-days holiday, plus bank holidays
  • Monthly €40 Treatwell vouchers
  • Mental health support through our partnership with Plumm
  • Growth funds for you to develop and grow with your team
