Senior DevOps Engineer

Job Overview

Hiro is seeking a DevOps Engineer to help scale, secure, and optimize the infrastructure powering the Stacks ecosystem. You'll be responsible for Kubernetes-based systems that underpin the Stacks Public Testnet, API Gateway, Chainhook-2.0, and Platform services, ensuring that our developer community and partners can build on reliable and observable infrastructure. DevOps engineers at Hiro are hybrid systems and software engineers with a two-pronged mission: Empower teams to build, test, deploy, and monitor services used by hundreds of thousands of users (soon to be millions) at scale with high velocity and quality. Eliminate toil across our engineering, IT, and other operations.

Key Responsibilities

• Architect and operate Kubernetes clusters across production, staging, and testnet environments.
• Build and manage API Gateway infrastructure (Kong, Istio) for high-scale external APIs.
• Deploy and monitor Chainhook-2.0 within Platform, ensuring resilient predicate registration and event streaming.
• Own Stacks Public Testnet reliability, including alerting, metrics, and incident response.
• Implement IaC (Terraform) for all infrastructure resources.
• Improve CI/CD pipelines for internal services deployed into private Kubernetes clusters.
• Enhance observability (Grafana, Prometheus, Loki) with SLO-based alerts and distributed tracing.
• Partner with blockchain and platform teams to ensure smooth rollouts and incident preparedness.
• Improve the tooling and automation for building, testing, and deploying software and services
• Collaborate with engineering teams on building / launching new products and features
• Evangelize and implement industry best practices to improve the security and ease-of-use of our production environment
• Diagnose problems from all sides and quickly narrow down potential solutions
• Debug production issues across services and multiple levels of the stack
• Improve operational standards, tooling, and processes
• Engineer solutions to automate, and streamline monitoring and incident escalation, improve resiliency and uptime

Required Qualifications

• 8+ years in DevOps/SRE roles operating high-availability distributed systems.
• Deep Kubernetes expertise (StatefulSets, Operators, Service Meshes, scaling strategies).
• Strong background in API infrastructure: load balancing, API Gateways (Kong, Nginx), rate limiting, caching.
• Proficiency with container technologies like Docker or Containerd
• Skilled in IaC (Terraform, Pulumi) and CI/CD (Actions, ArgoCD).
• Experience with observability stacks: Prometheus, Grafana, Loki, Jaeger/OTEL.
• Strong networking knowledge (L4/L7 load balancers, TLS termination, DNS, ingress controllers).
• Proficiency with scripting languages (Bash, Python, Go, or NodeJS).
• Cloud experience (AWS/GCP/Azure), ideally multi-cloud.
• Excellent communication skills and comfort working with a diverse team across time zones
• Great ownership, humility, and bias to action
• Able to see a problem from all sides and quickly narrow down potential solutions
• Experience deploying, scaling, and troubleshooting production services
