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
Interview process
- Talent Screen (15–30 min): Initial call to discuss your background, Cryptio, and the role
- Technical Interview (60 min): Deep dive into reliability, AWS, and debugging scenarios
- Team Interview (45 min): Meet an engineer and product manager to explore cross-team collaboration
- CTO Interview (45 min): Discussion about technical strategy, ownership, and your vision for reliability at Cryptio
If this sounds like you, we would love to hear from you 🙌
At Cryptio, we move fast and take ownership of outcomes. We learn from failures, celebrate wins, and let humility, curiosity, and a passion for crypto guide how we work. If you value collaboration and want to build with purpose, you’ll feel right at home here.
