Quicknode is backed by some of the world's best investors including Tiger Global, Y Combinator, SoftBank, and the Seven Seven Six Fund. The Quicknode team has over 120 people maintaining high performance global data infrastructure for amazing customers serving billions of requests daily.

We are a global remote company with an HQ in Miami, Florida.

The Role

As a Senior Infrastructure Engineer at QuickNode, you'll play a pivotal role in architecting, developing, and implementing our next-generation infrastructure platforms across both private and public clouds. This role focuses on building robust, scalable systems that go beyond traditional cloud deployments—developing hybrid environments that integrate bare-metal, virtualization, and orchestration technologies. You'll drive automation, standardization, and operational excellence across QuickNode's infrastructure ecosystem, ensuring performance, reliability, and scalability as we expand our Web3 infrastructure footprint globally.

What You'll Do
  • Research, architect, and deploy complex infrastructure systems across bare-metal servers, hypervisors, orchestrators, virtual machines, and containerized environments.

  • Design and implement automation using Infrastructure-as-Code and Configuration Management principles (Terraform, Ansible, Consul) to ensure reproducibility, speed, and consistency in infrastructure deployment.

  • Establish and maintain infrastructure standards, documentation, and architecture diagrams to support scale, reliability, and compliance across environments.

  • Partner with Technical Operations, CloudOps, and Platform teams to ensure smooth integration of systems, improve deployment efficiency, and enhance observability.

  • Optimize resource allocation and infrastructure cost efficiency while maintaining performance and uptime goals.

  • Continuously improve resilience and scalability through proactive capacity planning, disaster recovery testing, and infrastructure modernization initiatives.

What You'll Bring
  • Minimum 5 years of experience in Systems Administration, Datacenter Operations, or Infrastructure Engineering, with deep expertise in Linux/Unix systems

  • Proven success designing and managing hybrid cloud and traditional infrastructure platforms at scale (bare-metal, virtualized, and cloud-native).

  • Hands-on experience with automation, configuration management, and CI/CD tools such as Terraform, Ansible, Consul, and Jenkins.

  • Proficiency with observability and monitoring platforms (Grafana, ELK, VictoriaMetrics, DataDog).

  • Programming experience in one or more languages such as Python, Go, or JavaScript.

  • Strong understanding of infrastructure architecture principles — scalability, redundancy, fault tolerance, and cost optimization.

  • Familiarity with containerization (Docker, Kubernetes) and networking fundamentals across cloud and datacenter environments.

  • A proactive, analytical mindset and the ability to deliver under pressure while fostering a culture of continuous improvement and reliability.

  • Excellent communication and documentation skills to facilitate alignment across cross-functional engineering teams.

This role is eligible for a quarterly bonus tied to company and individual goal achievement.
