Note: The job is a remote job and is open to candidates in USA. Xometry is a company that powers the industries of today and tomorrow by connecting people with big ideas to manufacturers. They are seeking a Staff Cloud Security Engineer to own their cloud security posture and runtime detection capabilities, focusing on ensuring live cloud environments are hardened and continuously monitored.

Responsibilities

• Own CrowdStrike Falcon configuration, ensuring policies are appropriately scoped, tuned, and generating actionable alerts
• Partner with MDR to define alert routing, triage thresholds, and escalation logic, ensuring the right signals reach the right team
• Monitor cloud environments (primarily AWS) for security posture drift: misconfigured IAM roles, overly permissive security groups, exposed storage, and non-compliant resource configurations
• Secure Kubernetes clusters and containerized workloads: manage Network Policies, RBAC, Admission Controllers, and runtime detection for anomalous container behavior
• Develop and enforce cloud security policies and standards for AWS infrastructure, ensuring secure and scalable deployments align with organizational risk posture
• Evaluate and lead the implementation of additional detection tooling, including cloud SIEM platforms, designing detection rules and alerting pipelines
• Manage infrastructure as code (IaC) security using Terraform or OpenTofu — ensuring IaC definitions meet security standards before deployment
• Automate security posture checks and detection workflows using Python and shell scripting
• Stay current with the evolving cloud threat landscape and translate emerging threats into detection coverage or posture improvements

Skills

• Minimum 8 years of experience in cloud security, security engineering, or a related infrastructure security discipline
• Hands-on experience with a cloud security posture management (CSPM) platform — CrowdStrike, Wiz, Prisma Cloud, Orca, or equivalent. Prior CrowdStrike experience is a plus but not required
• Deep familiarity with AWS security architecture: IAM/SCP policy design, VPC networking, security groups, CloudTrail, and cloud-native security controls. GCP or Azure experience considered in lieu of AWS for strong candidates willing to expand into AWS
• Proficiency with infrastructure as code (IaC) tools such as Terraform, OpenTofu, or CloudFormation, with an understanding of how to enforce security standards within IaC workflows
• Strong Python and shell scripting skills for security automation, detection rule development, and tooling integration
• Must be a US Citizen or legal permanent resident (Xometry handles ITAR-controlled data)
• AWS GovCloud experience
• Hands-on Kubernetes security experience: securing and managing production clusters, including Network Policies, RBAC, and Admission Controllers
• Experience with cloud-native SIEM solutions, including writing detection rules in Python or SQL
• Experience securing microservices architectures, including service mesh security (Istio or Linkerd)
• Bachelor's degree in Computer Science, Information Security, or a related field

Benefits

• 401(k) match
• Medical, dental and vision insurance
• Life and disability insurance
• Generous paid time off including vacation, sick leave, floating and fixed holidays, maternity and bonding leave
• EAP, other wellbeing resources
