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.
Requirements
Essential:
1. Mindset and ways of working:
- Highly adaptable and comfortable with ambiguity, i.e. be able to switch focus and context at short notice and still deliver.
- Trustworthy and self-directed: can be handed mission-critical work and own it end to end.
- Uncompromising attention to detail. This is not optional for this role.
- A strong, collaborative team player who builds trust quickly across functions.
- Sound judgement under time pressure; calm and methodical when priorities shift.
2. Domain and functional expertise (primary requirement):
- Proven experience (5+ years) in QA or quali
