Description

This is a full-time position for a DevOps Engineer (typically 3+ years of experience) focused on building and operating reliable, scalable, and easy-to-use infrastructure.

You will work across our production and development environments, including CI/CD pipelines, cloud infrastructure, blockchain nodes, and internal services, to ensure that systems are stable, observable, secure, and straightforward to operate. This role sits at the intersection of infrastructure, automation, and developer enablement.

You will design and maintain the tooling that supports engineers, auditors, and operators: deployment pipelines, monitoring and alerting, secrets management, networking, and automation. Prior blockchain experience is not required; you will learn it on the job. What matters most is strong systems thinking, comfort with distributed systems, and a bias toward automation and reliability.

As with all roles at Common Prefix, we value first-principles thinking, pragmatic engineering, and infrastructure that stays out of the way rather than becoming a bottleneck.

Responsibilities

In this role, you will work across the following areas:

• Infrastructure and platform engineering
  • Design, build, and maintain infrastructure (cloud, on-prem, or hybrid) supporting blockchain nodes, validators, relayers, and internal services
  • Automate provisioning, configuration, and scaling of infrastructure using Infrastructure as Code
  • Containerize services and manage orchestration platforms (e.g. Docker, Kubernetes)
  • Manage networking components such as DNS, load balancing, TLS, VPNs, and firewalls
• CI/CD, automation, and developer enablement
  • Design and maintain CI/CD pipelines from development through production
  • Improve developer workflows by building tooling that makes deployments safe, repeatable, and fast
  • Identify manual or error-prone processes and automate them away
  • Collaborate closely with software engineers to understand their needs and support them with reliable infrastructure
• Reliability, monitoring, and security
  • Implement monitoring, logging, and alerting to ensure system health and fast incident response
  • Participate in incident response and post-incident improvements
  • Improve reliability, availability, and cost efficiency of production systems
  • Implement infrastructure security best practices, including secrets management and key handling
  • Participate in on-call rotations for production systems, always with shared ownership and senior support
• Knowledge sharing
  • Document infrastructure, runbooks, and operational procedures
  • Share DevOps and reliability best practices across the organization
  • Help evolve our internal platform and infrastructure culture
