Job Description:

Job Description Job Description Career Renew is recruiting for one of its clients a Senior Site Reliability Engineer - this is a fully remote role for US or Europe based candidates (as long as they can work EST hours) We are a fast-growing software company supporting and developing Hedera, an open-source, proof-of-stake, EVM-compatible public ledger built for enterprise and Web3 use cases. Hedera is governed by a global council of industry-leading organizations across multiple sectors and regions, ensuring long-term stability, decentralization, and sustainability. About the Role We are hiring a Senior Site Reliability Engineer to join the HashSphere engineering team. HashSphere is a greenfield, enterprise-focused distributed ledger platform built on Hiero, designed for private and consortium deployments with a strong emphasis on security, privacy, and scalability. This role is hands-on and high impact. You will own the design, deployment, and reliability of mission-critical, multi-region infrastructure used by large organizations across financial services, supply chain, and healthcare. You will partner closely with product, security, and platform leadership to shape architecture, reliability strategy, and operational standards from the ground up. This is not a support role. We are looking for someone who has operated real systems at scale, measured outcomes, and taken end-to-end ownership. What You’ll Do Design, build, and operate highly available, multi-region distributed systems with clear recovery strategies and tested RTO/RPO. Partner with the Head of SRE to define the reliability roadmap, platform architecture, and operational standards. Own large-scale Infrastructure as Code using Terraform, including reusable modules, multi-account patterns, and policy guardrails. Operate and scale Kubernetes environments (EKS, GKE, or AKS) using GitOps practices (ArgoCD), Helm, and strong RBAC and network policies. Build and maintain secure CI/CD pipelines, including blue/green and canary deployments, promotion and rollback strategies, and artifact integrity (SBOM, signing). Define and improve SRE practices, including SLOs, error budgets, observability, and measurable reductions in MTTR/MTTA. Work closely with product and engineering teams to translate customer and business requirements into reliable, secure platform services. Contribute to the operational support and continuous improvement of customer-facing HashSphere deployments. Required Qualifications 7 years of experience in SRE, platform engineering, or infrastructure engineering operating production distributed systems. Strong multi-cloud experience (AWS, GCP, or Azure), with SME-level depth in AWS or GCP. Proven experience running multi-region production systems, including disaster recovery testing, runbooks, and real incident ownership. Deep, hands-on experience with Kubernetes at scale (EKS/GKE/AKS), including GitOps workflows and production-grade security controls. Extensive experience with Terraform-first Infrastructure as Code in large, real-world environments (not POCs). Strong security and compliance mindset, including Zero Trust principles, secrets management (Vault or cloud-native equivalents), and exposure to regulated environments (PCI, SOC 2, HIPAA, NIST). Comfortable owning systems end to end, with clear metrics and outcomes to show impact. Nice to Have Experience with distributed ledger or blockchain systems, particularly private or consortium deployments. Familiarity with Hedera services such as HCS, HTS, Hedera SDKs, or the Smart Contract Service. Understanding of EVM-based systems and smart contract tooling (Solidity, Hardhat). Experience operating active-active, globally distributed architectures. Prior experience supporting financial services or other highly regulated industries. Compensation & Package Equity & Tokens Performance Bonuses Health insurance & 401k for US employees only.
