## Description

We are a high-growth software company supporting the development of a premier open-source, EVM-compatible public ledger built for global enterprise and Web3 use cases. We are currently hiring a Senior Site Reliability Engineer for our "greenfield" enterprise-focused team. This team is building a private and consortium distributed ledger platform designed specifically for sectors with high security and privacy requirements, such as financial services, healthcare, and supply chain.
This is a hands-on, high-impact role where you will own the design, deployment, and reliability of mission-critical, multi-region infrastructure. This is not a traditional support role; we are looking for an engineer who has operated real systems at scale and is eager to take end-to-end ownership of architecture and operational standards from the ground up., + Systems Architecture: Design and operate highly available, multi-region distributed systems with rigorous recovery strategies (RTO/RPO).

 + Infrastructure as Code: Own large-scale IaC using Terraform, developing reusable modules and multi-account patterns with policy guardrails.
 + Kubernetes Orchestration: Scale production environments (EKS, GKE, or AKS) utilizing GitOps (ArgoCD), Helm, and strict network policies.
 + CI/CD Leadership: Build secure pipelines supporting blue/green and canary deployments, artifact signing (SBOM), and automated rollback strategies.
 + SRE Advocacy: Define and improve SLOs, error budgets, and observability metrics to drive measurable reductions in MTTR.
 + Collaboration: Partner with the Head of SRE and VP of Engineering to translate complex business requirements into reliable, secure platform services.
