The Opportunity

We’re hiring a Site Reliability Engineer (SRE) to strengthen the reliability, observability, and performance of Cryptio’s platform. You'll work across our stack, with a heavy focus on AWS and Kubernetes, helping to make our systems faster, more stable, and easier to operate.

This is a role for a hands-on builder who can trace complex issues, design reliability into everything we ship, and take ownership of both infrastructure and application reliability. You’ll collaborate closely with senior engineers and the CTO to implement our reliability roadmap, improve monitoring and incident management, and automate our infrastructure.

It’s a great opportunity for an experienced SRE/Platform Engineer ready to lead in Kubernetes and AWS environments, take ownership of complex systems, and grow into senior reliability responsibilities.

What you'll do

• Drive reliability improvements across AWS and Kubernetes, as well as application layers

• Enhance observability by refining logs, metrics, and traces

• Support incident response and contribute to postmortem analysis and automation

• Maintain and evolve AWS and Kubernetes environments with a focus on scalability and cost efficiency

• Has hands-on experience with databases such as PostgreSQL, Cassandra, or ClickHouse

• Knows at least one programming language well enough to debug and improve systems

• Has used Infrastructure-as-Code tools like Pulumi or Terraform

• Enjoys debugging complex systems and improving performance or reliability

• Communicates clearly and collaborates effectively with software teams

• Is curious, systematic, and eager to grow into a senior reliability role

• (Bonus) Experience or interest in Rust, TypeScript, or crypto/finance/data systems

Why you’ll love this role

• Work on a high-impact platform powering top crypto and finance institutions
