Senior QA Engineer

We are looking for an exceptional individual to join the Core Platform team as a Senior QA Engineer. This is a deliberately versatile role: rather than owning a single feature area, you will act as a trusted quality specialist we can deploy onto whatever is most critical at any given moment: the mission-critical, time-sensitive work that is difficult to plan for in advance and that we need handled with confidence and minimal ramp-up. Success depends first on mindset: genuine flexibility, sound judgement under pressure, and uncompromising attention to detail; and second on deep functional knowledge of our products across the Core Platform, Onboarding, Payments, PSP, Trading, Loyalty, and Operations.  • Take ownership of whatever is most critical at a given time, often at short notice and with limited time to plan —moving quickly into a problem, understanding the risk, and driving it to a confident resolution. 

• Operate with the autonomy and judgement that let the team fully entrust mission-critical, time-sensitive work to you without close oversight. 

• Apply rigorous, non-negotiable attention to detail, surfacing the edge cases, subtle regressions, and quiet failure modes that others miss. 

• Build and continuously deepen functional expertise across all Core Platform domains including Onboarding, Payments, PSP, Trading, Loyalty, and Operations; Understanding not just how each domain works but why it matters and where the real business and client risk sits, so testing effort is always aimed at what counts. 

• Act as a go-to reference on product behaviour and quality risk for engineering, product, and operations partners, working as an embedded team player across squads. 

• As a secondary focus, translate this domain expertise into a sharper automation strategy by critically vetting what is genuinely worth automating and pushing back on low-value coverage, so we test what actually matters with no fluff. 

• Partner with engineering to ensure automated coverage targets the highest-risk, business-critical paths rather than chasing coverage metrics for their own sake. 

• Provide hands-on test support across front-end and back-end changes, user workflows, performance, and security when needed.
