The role, at a glance.
ecosio is seeking a senior cloud security engineer to improve the security posture of AWS, Kubernetes, infrastructure-as-code, and microservices environments. The role combines hands-on implementation of security tooling and controls with threat modeling, misconfiguration remediation, and security automation. It also supports audits, compliance initiatives, and certifications such as ISO 27001 and SOC 2 while partnering with engineering teams and the Security Chapter. Strong practical experience with AWS, Kubernetes, Terraform, GitLab CI, ArgoCD, and a scripting or programming language is central to success.

Sample interview questions
I would begin with an inventory and risk assessment covering IAM, network segmentation, logging, encryption, cluster access, workload identities, image provenance, and secrets management. I would prioritize high-impact controls such as least-privilege IAM, private endpoints where appropriate, admission controls, image scanning, runtime monitoring, centralized audit logs, and policy-as-code integrated into deployment pipelines.
I would add automated checks at merge-request and deployment stages, including secret detection, dependency and container scanning, IaC scanning, policy validation, and Terraform plan review. Findings should have clear severity thresholds, block releases only for agreed critical risks, and create actionable remediation guidance so controls support delivery rather than becoming a manual bottleneck.
I define the system boundaries, assets, data flows, identities, trust boundaries, and external dependencies with the engineering team. I then identify likely threats using a structured method such as STRIDE, prioritize them by likelihood and impact, document mitigations, and convert the highest-value controls into design requirements and automated verification where possible.
I would maintain evidence showing that controls are designed and operating effectively, such as access reviews, change-management records, vulnerability-management reports, security training records, incident-response exercises, logging configurations, backup tests, and policy attestations. I would automate evidence collection where practical and map each artifact to the relevant control requirements.
For engineers, I would provide the affected resource, attack path, risk severity, recommended configuration change, and validation steps. For non-technical stakeholders, I would summarize the business impact, likelihood, remediation timeline, ownership, and any residual risk in plain language without unnecessary implementation detail.
