🎯 Who Kaluza Is Looking For

  • Has hands-on scripting experience in Python or Go, with demonstrable projects automating security tasks or integrating security tooling.
  • Possesses deep, practical knowledge of AWS/GCP security, Kubernetes security, and infrastructure-as-code (especially Terraform), ideally in energy or SaaS contexts.
  • Has experience managing web application firewalls like Cloudflare and can articulate how they've used them to protect dynamic, cloud-native applications.
  • Is not just aware of OWASP Top 10 and DevOps security principles, but can discuss how they've applied them in CI/CD pipelines to shift security left.

📝 Tips for Applying to Kaluza

1

Highlight specific examples where you've integrated security platforms to prevent, detect, or respond to threats, especially in AWS/GCP environments.

2

Tailor your resume to show how you've partnered with engineering teams (like Platform or IAM) to implement security controls, not just worked in isolation.

3

Mention any experience in energy, utilities, or decarbonization tech, as this shows alignment with Kaluza's mission.

4

Include a link to a GitHub repo or portfolio with Terraform scripts, Python/Go security tools, or Kubernetes security configurations.

5

Explain in your application how you've cultivated a collaborative security culture in past roles, as this is explicitly called out in the job description.

✉️ What to Emphasize in Your Cover Letter

['Your experience embedding security into DevOps/CI/CD pipelines and how it enabled rapid, secure delivery of systems.', 'Specific projects where you implemented Zero Trust architecture or privileged access management (PAM) controls in cloud environments.', 'How your work has empowered product or engineering teams to prioritize and mitigate risks, with metrics or examples if possible.', "Why you're passionate about applying security skills to decarbonization and energy technology, referencing Kaluza's mission."]

  • → Recent news on Kaluza's partnerships or projects in the energy sector, to discuss their impact in interviews.
  • → Their culture and values, as the role emphasizes collaboration and empowering teams—be ready to align with this.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Walk us through how you'd design and implement a Zero Trust architecture for a cloud-native SaaS platform on AWS/GCP.
2 Describe a time you integrated a security tool (like a WAF or monitoring platform) into a CI/CD pipeline and the outcomes.
3 How would you approach securing a Kubernetes cluster for a multi-tenant application, considering Kaluza's product teams?
4 Discuss a scenario where you had to balance security requirements with rapid product delivery, and how you collaborated with engineers.
5 What AWS/GCP security services or best practices would you prioritize for protecting an energy data platform, and why?

⚠️ Common Mistakes to Avoid

  • Submitting a generic security resume without tailoring it to cloud security, scripting, or infrastructure-as-code as required.
  • Focusing only on defensive security without showing experience in proactive threat prevention or collaboration with engineering teams.
  • Failing to demonstrate knowledge of how security integrates into DevOps/CI/CD, as this is core to the role's responsibilities.
