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.
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.
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.
Our QA context
Treatwell Connect is a SaaS platform with web and mobile surfaces. The product moves fast, and what breaks has a direct impact on the livelihoods of the beauty & wellness businesses that depend on it every day. You will work alongside a junior QA specialist and a mid-level QA analyst,



reporting to the QA Team Lead, with engineering and product leadership actively invested in where this function goes.
5+ years of QA experience with hands-on automation work and structured manual and exploratory testing. You take satisfaction from shifting how a team thinks about testing, not just from shipping test suites. Quality culture is something you actively build, not something you leave to others.
~ You influence without authority: you bring developers, designers and product closer to quality, and the habits you build outlast your direct involvement.
~ You want to make the people around you better, and you're patient enough to do it consistently.

Experience with observability and monitoring tools, particularly Datadog. Knowing how to read production signals and connect them to your testing strategy is a meaningful advantage.
Experience working across web, mobile, and API surfaces in a single product. Experience with SQL for data validation, debugging, and exploratory testing. Ability to write queries to trace data flows, verify backend logic and support root cause analysis across distributed systems is a plus.
We’re the industry’s smartest salon management software, all connected to Europe’s leading bookings platform, working with over 50,000 salon partners across 13 countries, processing over 8 million bookings every month. We’re on an exciting journey to digitally revolutionise the hair and beauty community. 28-days holiday, plus bank holidays
~ All qualified applicants will receive consideration without regard to their condition.
