Note: The job is a remote job and is open to candidates in USA. Xometry is a digital marketplace that connects manufacturers with buyers and provides access to global manufacturing capacity. The Staff Cloud Security Engineer will lead cyber resilience efforts by designing an isolated AWS recovery environment, standardizing infrastructure as code, automating restoration workflows, and validating recovery capabilities. The role also leads recovery exercises and influences high-availability and security architecture across the engineering organization.
Responsibilities
- Design and build our Isolated Recovery Environment — a hardened AWS account with immutable vaults that break the attacker’s kill chain before it reaches our data
- Threat model our environment with a deep understanding of cloud-native attack patterns: IAM privilege escalation, backup deletion, ransomware persistence, and lateral movement across accounts
- Validate and continuously improve backup configurations to ensure recoverability, not just existence
- Lead our transition to 100% Infrastructure as Code. Every asset (VPCs, IAM roles, security groups) must be defined in Terraform so we can redeploy the entire stack into a clean account via automated pipeline
- Build automated recovery workflows that can tear down a compromised environment and bootstrap a fresh, hardened one from verified code and clean data
- Write and maintain executable recovery playbooks that detail the exact API calls and CLI commands needed to restore the application — tested, versioned, and runnable, not static documents
- Develop automated scripts (Python or Go) to smoke test recovered data and validate integrity post-restoration
- Lead regular hands-on recovery drills that simulate total loss of a critical environment and full recovery into a secondary clean account. Own the after-action process and drive improvements
- Act as the resilience authority for the engineering organization — shaping high-availability architecture decisions, influencing design reviews, and raising the floor on how we think about recoverability
- Partner with the Site Reliability Engineering team on multi-region deployments and high-availability design, ensuring cyber resilience is embedded in architecture from the start
- Champion IaC and immutable infrastructure practices across teams, not just within your own workstream
Skills
- 8+ years of experience in complex cloud environments (any of AWS/GCP/Azure), including at least 3 years in AWS. EKS/Kubernetes experience is a strong plus
- Strong Terraform skills. You should be able to modularize complex environments so they are environment-agnostic
- Hands-on familiarity with the Secure Vault pattern: protecting data in a separate, highly restricted AWS account with tight network controls
- Advanced shell scripting and proficiency in either Python or Go to automate restoration tasks that native AWS tooling doesn't cover
- Experience with CI/CD tooling (Scalr, GitHub Actions, or equivalent) to enable broad adoption of recovery pipelines across the organization
- Proven ability to engineer and automate end-to-end restoration workflows
- Hands-on experience leading technical recovery efforts from an actual cyber attack or destructive incident
- Experience with chaos engineering tooling to stress-test recovery assumptions
- Familiarity with NIST SP 800-34 (Contingency Planning) or similar frameworks
- AWS Security Specialty certification or equivalent demonstrated expertise
Benefits
- Bonus depending on factors such as job-related skills, relevant experience, and location
- 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
