How to Apply for Security Operations Engineer

at Critical Loop

🏢 About Critical Loop

Critical Loop is unique because it combines energy storage hardware with advanced software controls to make power more accessible and efficient. Working here means contributing to sustainable energy solutions at the intersection of physical infrastructure and digital innovation, with a focus on distributed edge systems that power real-world applications.

About This Role

This Security Operations Engineer role involves securing distributed edge nodes across energy storage systems, implementing security controls like network segmentation and secrets management, and translating compliance requirements into scalable implementations. It's impactful because you'll directly protect critical infrastructure that enables efficient power distribution while working across cloud and edge environments.

💡 A Day in the Life

A typical day might involve reviewing security telemetry from distributed edge nodes, automating security controls using infrastructure-as-code tools, collaborating with engineering teams on secure system designs, and documenting security implementations for compliance frameworks. You'll balance proactive security engineering with operational monitoring and incident response across hybrid cloud and edge environments.

Practice questions for this role

🎯 Who Critical Loop Is Looking For

  • Has 7+ years total experience with at least 2 years in Security Operations, specifically with Linux-based systems in cloud, on-premise, and edge/IoT environments
  • Demonstrates hands-on experience with infrastructure-as-code tools like Terraform and Ansible, plus scripting to automate security tasks
  • Can provide concrete examples of documenting and implementing security/compliance frameworks like ISO 27001 or SOC 2
  • Shows experience with securing distributed systems, particularly around hardening baselines, secure provisioning, and telemetry for edge nodes

📝 Tips for Applying to Critical Loop

1

Highlight specific experience with edge/IoT security, not just cloud or on-premise systems, since the role focuses on distributed edge nodes

2

Include metrics or examples showing how you've automated security operations tasks through scripting (Python, Bash, etc.)

3

Mention any energy, utilities, or critical infrastructure security experience, as this aligns with Critical Loop's domain

4

Demonstrate understanding of both compliance frameworks (ISO 27001/SOC 2) AND practical implementation in technical environments

5

Show how you've partnered with engineers to design secure systems, not just operated security tools independently

✉️ What to Emphasize in Your Cover Letter

['Your experience securing distributed systems, particularly edge/IoT environments similar to energy storage nodes', 'Examples of translating security/compliance requirements into practical implementations using automation', "How you've collaborated with engineering teams to build secure systems from design through operation", "Why you're specifically interested in Critical Loop's mission of making power more accessible and efficient"]
