Security Architect (f/m/d)

About ITRex

THE PLACE

ITRex - AI pioneers who build systems that actually work in the real world, not just in demos. We're 250+ people spread across the US and Europe, creating solutions for companies like Procter & Gamble 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 Security Architect to be the single technical owner of security and privacy assurance for a self-custody crypto wallet during its first delivery phase. Keys are generated, stored and used on the user's own device, in code that has already been distributed through the app stores - a defect on the signing path can't be fixed server-side or pulled back from devices that already hold the build. Security work here is preventive and continuous, not a hardening phase before launch. You will report to the Project Manager / Delivery Lead, work daily alongside the wallet SDK integration, backend, mobile and DevOps engineers and QA, co-sign the exit checklist of every milestone, and act as the technical counterpart to the independent auditor engaged by the client.
