Senior Infrastructure Engineer

About the Role: Our core mission at Railway is to make software engineers higher leverage. We are looking for a Senior Infrastructure Engineer to build the platform that Railway engineers run on. This is a high-impact, internal-facing role with a direct effect on company culture, trajectory, and outcome, focusing on baremetal orchestration and system reliability.

What You'll Do

• Build and maintain our host provisioning stack: PXE boot, Ansible, and burn-in agents that bring new bare metal online quickly.
• Evolve our homegrown orchestration engine to manage clusters, containers, and VMs through a single lens.
• Optimize the efficiency of our bin packing algorithm to maximize utilization/performance and minimize costs.
• Define immutable infrastructure using Terraform and Ansible, and design CI pipelines that ship code safely.
• Build Golang/Rust GRPC services from scratch capable of supporting millions of users.

What You Bring

• A strong understanding of distributed systems and what it takes to operate them resiliently.
• Hands-on experience with bare metal provisioning, configuration management, and getting hardware production-ready.
• Comfort building and operating internal tools, understanding that internal developer experience matters.
• Grit to dive into ambiguity, implement solutions, scale them, and replace them when needed.
• Great communication skills for getting your point across and solutions implemented.

Benefits

• Best in class benefits including a great salary and full health benefits (including dependents).
• Strong equity grants and an equipment stipend.
• A culture of high autonomy, high ownership, and very few meetings.
• 100% remote work flexibility, distributed globally.
