About ITRex
THE PLACE
ITRex - AI pioneers who build systems that actually work in the real world, not just in demos. We're 200+ people spread across the US and Europe, creating solutions for companies like P&G and Shutterstock. We keep it simple, build it right, and focus on what works.
THE PEOPLE
We're the kind of people who don't ignore messages in Slack, who jump in to help when you're stuck on a problem, and who offer solutions instead of blame when things go sideways. We believe in openness, accountability, and having each other's backs. No office politics, no hidden agendas - just people who care about doing good work together and supporting each other to get there.
THE ROLE
We are looking for a QA Engineer to join a high-scale product in the digital finance / blockchain domain.
Our client is a globally distributed tech company building high-load, security-critical solutions used by millions of users. The product ecosystem includes mobile, desktop, and web applications, with a strong focus on mobile.
You will own quality across the full release cycle, working closely with engineering, product, and stakeholders. Your work will directly impact the reliability and security of large-scale financial systems.
