Reliability Engineer

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 Founding 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.
