MLabs is hiring a Senior Site Reliability Engineer for a greenfield enterprise-focused team. You will build a private and consortium distributed ledger platform for sectors with stringent security and privacy needs.

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

What We're Looking For

  • 7+ years of experience in SRE, Platform Engineering, or Infrastructure Engineering operating production distributed systems.
  • Deep expertise in AWS or GCP, with experience running multi-region production environments and disaster recovery testing.
  • Hands-on experience with Kubernetes at scale, including GitOps workflows and production-grade security controls.
  • Strong background in Zero Trust principles, secrets management (Vault), and compliance frameworks like SOC 2, HIPAA, or NIST.
  • Extensive experience with Terraform-first infrastructure in large-scale, real-world environments.

Nice to Have

  • Experience with distributed ledger technology or blockchain systems, particularly private or consortium deployments.
  • Familiarity with EVM-based systems and smart contract tooling such as Solidity or Hardhat.
  • Experience operating active-active, globally distributed architectures.
  • Background in supporting financial services or other highly regulated industries.

Technical Stack

  • Terraform
  • Kubernetes (EKS, GKE, AKS)
  • GitOps (ArgoCD)
  • Helm
  • AWS, GCP
  • Vault

Team & Environment
