[Hiring] Senior QA Engineer @Treatwell

Role Description

We are 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.

• Build an automation framework from scratch, starting with API-level coverage of critical end-to-end happy path flows, the ones that must never break in a product shipping multiple times a day.
• Mentor QA team members into more technical and structured testing practice.
• Work with developers to build shared ownership of quality across engineering: encourage better unit testing, help them understand what good coverage looks like, and shift quality from a QA concern to a team habit.
• 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 from what you find.
• Identify gaps that developers and PMs miss and bring them to the table early, contributing to product decisions throughout the cycle, not just at the end.
• Track QA metrics that matter, bug detection rate, release confidence, post-release defect counts, and own the narrative around what they mean for the product.

Qualifications

• 5+ years of QA experience with hands-on automation work and structured manual and exploratory testing.
• Experience building automation frameworks, not just using them.
• Fluent in at least one programming language and capable of making and defending tooling decisions.
• Ability to shift how a team thinks about testing and actively build a quality culture.
• Influence without authority and bring developers, designers, and product closer to quality.
• Articulate risks clearly to engineers, PMs, and non-technical stakeholders.
• Desire to make the people around you better and demonstrate patience in doing so.

Requirements

• 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.

Benefits

• 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.
