Staff Infrastructure Engineer (Generalist) at Crusoe

Role Overview

Crusoe is on a mission to accelerate the abundance of energy and intelligence, crafting the engine that powers a world where people can create ambitiously with AI — without sacrificing scale, speed, or sustainability. We are seeking a Staff Infrastructure Engineer to secure the foundations of Crusoe Cloud, our purpose-built compute platform for AI and high-performance workloads. This role focuses on designing and embedding security controls directly into our global infrastructure, enabling customers to train advanced models within a trusted, secure-by-default environment.

Your expertise will be crucial in ensuring the security and integrity of our cloud platform.

A Day in the Life

• Championing Infrastructure-as-Code (IaC) standards (e.g., Terraform) to enforce secure defaults, immutability, and drift detection.
• Building automated security guardrails embedded directly into CI/CD and deployment pipelines.
• Collaborating on a centralized Vault-as-a-Platform service to manage secrets, encryption keys, and internal PKI.
• Designing and operating certificate lifecycles (X.509, SSH) to support secure machine-to-machine trust.
• Driving adoption of short-lived, Just-In-Time (JIT) access models to reduce standing privileges and improve auditability.
• Securing core network foundations, including global DNS architecture, service discovery, and network authentication systems.
• Designing and maintaining authentication controls for network infrastructure to ensure secure, monitored access.
• Partnering closely with infrastructure, platform, and SRE teams to identify and remediate security gaps in foundational systems.
