Senior Site Reliability Engineer

Shape the reliability experience of an always-on crypto platform delivering seamless service across North America and Europe.

As an SRE, you'll be leading the charge in designing active-active failover, cross-region routing, and distributed services that are resilient to cloud outages and geopolitical quirks. This is real-world chaos engineering at a global scale.
You’ll lead the creation of a region-aware CI/CD pipeline with canary deployments, automated rollbacks, and feature flags tailored per continent.

Join us remotely, you can be located anywhere in Europe within the CET/CEST time zones, as our work is 100% remote. This is a full-time position.
