How to Apply for Staff Infrastructure Engineer (Generalist)

at Crusoe

🏢 About Crusoe

Crusoe is uniquely positioned at the intersection of energy innovation and cloud computing, transforming stranded or wasted energy (like flared natural gas) into eco-friendly power for modular data centers. This mission directly reduces carbon emissions and environmental impact, making it a compelling choice for engineers passionate about sustainability and cutting-edge infrastructure. Working here means contributing to a tangible solution for climate change while building a global cloud platform.

About This Role

As a Staff Infrastructure Engineer (Generalist) at Crusoe, you'll architect and enforce security controls across the entire stack of their global cloud platform, focusing on compute, networking, and storage layers. This role is impactful because you'll champion Infrastructure-as-Code (IaC) standards like Terraform to build secure, immutable infrastructure and embed automated security guardrails directly into CI/CD pipelines, ensuring the platform's integrity as it scales. You'll also design and operate critical trust systems like certificate lifecycles (X.509, SSH) for machine-to-machine communication.

💡 A Day in the Life

A typical day might involve collaborating with remote teams to design security controls for new cloud platform features using Terraform, reviewing IaC code for compliance with secure defaults, and troubleshooting certificate lifecycle issues for machine-to-machine authentication. You could also spend time automating security checks into deployment pipelines or optimizing infrastructure to support Crusoe's energy-efficient data centers, balancing technical depth with the company's sustainability goals.

Practice questions for this role

🎯 Who Crusoe Is Looking For

  • Has 8+ years of hands-on experience in infrastructure engineering, SRE, or security engineering, with a proven track record of using Terraform to manage complex, multi-environment infrastructure at scale.
  • Possesses deep, practical knowledge of security principles across the entire stack—from Linux/container runtimes (e.g., Docker, Kubernetes) to cloud control planes (likely AWS, GCP, or Azure), not just theoretical understanding.
  • Demonstrates strong expertise in cryptography, secrets management (e.g., HashiCorp Vault), PKI, and modern authentication standards (e.g., OAuth, mTLS), with experience designing certificate lifecycles for production environments.
  • Is a proactive champion of Infrastructure-as-Code (IaC) who can enforce secure defaults, immutability, and drift detection, and has built automated security guardrails into CI/CD pipelines (e.g., using tools like Checkov, OPA, or custom scripts).

📝 Tips for Applying to Crusoe

1

Tailor your resume to highlight specific projects where you used Terraform at scale to manage multi-environment infrastructure, emphasizing security outcomes like enforcing immutability or detecting drift.

2

Explicitly mention experience with cryptography, PKI, and secrets management in your application—Crusoe's focus on certificate lifecycles and machine-to-machine trust makes this non-negotiable.

3

Research Crusoe's energy-to-cloud model and mention in your cover letter how your infrastructure skills align with their mission of building a sustainable, global cloud platform.

4

Provide concrete examples of automated security guardrails you've embedded into CI/CD pipelines, such as pre-deployment policy checks or post-deployment compliance scans.

5

If you have experience in remote-first environments, highlight your ability to collaborate asynchronously and manage infrastructure across time zones, as this role is fully remote.

✉️ What to Emphasize in Your Cover Letter

["Explain how your 8+ years of infrastructure/security engineering experience directly applies to architecting security controls for Crusoe's global cloud platform, citing specific technologies (e.g., Terraform, Linux, cloud providers).", "Demonstrate your passion for sustainability by linking your technical skills to Crusoe's mission of transforming stranded energy into eco-friendly data center power.", 'Highlight a past project where you championed Infrastructure-as-Code (IaC) standards to enforce security, immutability, or drift detection, showing quantifiable results if possible.', 'Briefly describe your hands-on experience with cryptography, PKI, or certificate lifecycles, emphasizing how it supports secure machine-to-machine trust in distributed systems.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Deep-dive into Crusoe's core technology: how they convert stranded energy (e.g., flared gas) into power for modular data centers, and their cloud platform's role in this ecosystem.
  • → Explore their public content (blog, news) about infrastructure, security, or sustainability initiatives to understand their technical priorities and company culture.
  • → Investigate their likely cloud providers and tech stack—given the remote, global nature of the role, look for mentions of AWS, GCP, Azure, Kubernetes, or similar in job postings or engineering articles.
  • → Learn about the environmental impact of data centers and how Crusoe's model reduces carbon emissions, as this mission-driven aspect is central to their identity.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Walk us through how you've used Terraform to manage complex, multi-environment infrastructure at scale, including how you enforced secure defaults and handled drift detection.
2 Describe your approach to designing and operating certificate lifecycles (X.509, SSH) for machine-to-machine trust in a production environment. What challenges have you faced?
3 How have you embedded automated security guardrails into CI/CD pipelines? Provide an example of a policy or check you implemented and its impact.
4 Explain your understanding of security principles across the stack, from Linux/container runtimes to cloud control planes. How do you secure each layer in a global platform?
5 Crusoe's platform relies on sustainable energy sources. How might infrastructure decisions (e.g., resource allocation, cooling) align with environmental goals in a cloud setting?

⚠️ Common Mistakes to Avoid

  • Applying with a generic resume that doesn't specifically highlight Terraform experience at scale, cryptography/PKI knowledge, or security engineering in infrastructure contexts—Crusoe's requirements are highly specific.
  • Failing to demonstrate how your work aligns with sustainability or Crusoe's energy-to-cloud mission, which could suggest a lack of cultural fit for this purpose-driven company.
  • Overemphasizing theoretical security knowledge without providing concrete examples of hands-on implementation in infrastructure, CI/CD pipelines, or certificate management.
