Senior Infrastructure Engineer

You'll design, operate, and scale the systems that power our platform, working at the intersection of distributed systems, security, and cloud infrastructure to keep everything reliable, secure, and performant. You'll build and maintain the infrastructure that supports wallet services, transaction processing, and blockchain integrations. Beyond day-to-day operations, you'll help design resilient architectures, automate operations, and improve how deployments, monitoring, and security are handled. You'll collaborate closely with engineering, product, and security teams to deliver infrastructure that scales with real-world financial workloads.
