The Opportunity

We’re hiring a Site Reliability Engineer (SRE) to help strengthen the reliability, observability, and performance of Cryptio’s platform. You’ll work across our stack, from AWS infrastructure to Rust and Type Script services, helping to make our systems faster, more stable, and easier to operate.

This is a role for a hands-on builder who can see across systems, trace complex issues, and design reliability into everything we ship. You’ll collaborate closely with senior engineers and the CTO to implement our reliability roadmap, improve monitoring and incident management, and build automation across our infrastructure.

It’s a great opportunity for a mid-level SRE or Dev Ops engineer ready to take ownership of complex systems and grow toward senior reliability responsibilities.
