About Cryptio
We’re Cryptio. We build infrastructure to bring financial integrity to the crypto economy. Our enterprise-grade back-office and data platform power mission-critical accounting, reporting, and operational workflows for institutions, corporates, and crypto-native organisations.
We’re trusted by leaders like Circle, Societe Generale, Uniswap, Gemini, and the Government of El Salvador. We’ve raised $26m from top investors including Point Nine, 1kx, Tim Draper, and Ledger Cathay.
The opportunity
We’re hiring a Senior Site Reliability Engineer (SRE) to take full ownership of Cryptio’s reliability, observability, and incident response. You’ll work across our stack—from AWS infrastructure to Rust microservices, TypeScript indexers, and data-heavy backends—to ensure our platform remains fast, stable, and resilient as we scale.
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 engineering and product teams to define SLAs/SLOs, strengthen monitoring and alerting, improve incident management, and build the processes and tooling that make reliability a shared culture at Cryptio.
Key technologies
AWS (EKS, S3, GuardDuty, Route53, IAM, and more)
Rust, TypeScript (Nest.js, React, OpenAPI)
PostgreSQL, Cassandra, ClickHouse
Pulumi, GitLab CI, Docker, Kubernetes
Grafana, Prometheus, Loki, Jaeger
What you’ll do
Own reliability end-to-end: design, measure, and improve service availability, latency, and performance across Cryptio’s platform
Enhance observability: expand and refine metrics, logs, and traces to provide deep insight into our Rust and TypeScript services
Lead incident management: define playbooks, improve response workflows, and foster a blameless postmortem culture
Strengthen infrastructure: optimise AWS configurations, CI/CD pipelines, autoscaling, and networking for reliability and cost efficiency
Collaborate across teams: work with product and engineering leads to ensure reliability is considered at every design stage
Drive continuous improvement: identify systemic weaknesses, automate recovery where possible, and reduce MTTR across the stack
Champion SRE best practices: guide teams on capacity planning, runbooks, and resilience testing
What we’re looking for
5+ years of experience in Site Reliability, DevOps, or Infrastructure Engineering roles
Deep understanding of distributed systems and debugging at the network, application, and database layers
Hands-on experience with AWS, container orchestration (Kubernetes, ECS), and Infrastructure-as-Code tools (Pulumi or similar)
Comfortable tracing through Rust and TypeScript code to diagnose complex performance or reliability issues
Experience with (or willingness to learn) Cassandra and ClickHouse in production
Strong collaborator with excellent communication skills
Systematic, analytical, and passionate about building reliable systems at scale
Interest in (or curiosity about) crypto, finance, or large-scale data systems
Why you’ll love this role
True ownership of reliability and uptime across a critical, fast-growing SaaS platform
Opportunity to shape SRE culture and processes from the ground up
Work with a world-class engineering team at the intersection of crypto, accounting, and data infrastructure
Freedom to experiment and improve observability, alerting, and recovery pipelines end-to-end
100% remote (UK only), with opportunities to visit our Paris or London hubs
Competitive salary and full benefits package
