About QuilrAI
QuilrAI is the first agent-native company that secures and operationalizes the agentic enterprise across the entire agent lifecycle. Foundation models are non-deterministic, so protecting agents only at runtime leaves every decision to the last millisecond and every alert to the security team. QuilrAI treats AI as a deployment problem first: every agent is assessed, governed against policy, and deployed from an approved blueprint before it reaches production; every action it takes is decided before it executes; and every outcome is proven after it runs. Founded by security veterans and deployed across, QuilrAI is headquartered in Austin, Texas. Make every agent matter.
Why Join Us
We are building the infrastructure that makes safe, autonomous AI a reality for the enterprise. Joining our team means tackling unsolved engineering and security challenges at the absolute cutting edge of agentic AI. We operate with high velocity, value ownership, and are backed by top-tier investors. If you want to shape how the world's most advanced AI systems are governed and deployed, we want you on board.
About the Role
You will own the day-to-day administration, reliability, automation, and security of our internal IT and cloud infrastructure across Linux, Windows, identity, endpoints, networking, and DevOps platforms.
What You Will Do
Linux and Windows Server Administration
Administer Linux and Windows servers, including operating-system provisioning, configuration, monitoring, patching, upgrades, and lifecycle maintenance.
Apply secure-hardening standards and troubleshoot performance, availability, authentication, and application issues through root-cause analysis and documented remediation.
Identity, SSO, MFA, and Access Management
Manage identity platforms, SSO integrations, MFA policies, roles, groups, and least-privilege access across corporate and cloud systems.
Conduct periodic access reviews and execute timely onboarding, role-change, and offboarding workflows in partnership with People and functional teams.
Endpoint and SaaS Administration
Manage corporate endpoints through MDM, including enrollment, configuration profiles, security baselines, software deployment, compliance monitoring, and remote support.
Administer key SaaS platforms such as GitHub, Google Workspace or Microsoft 365, Jira, and Slack, including licensing, integrations, permissions, and user support.
Networking, VPN, DNS, Backups, and Disaster Recovery
Maintain office and cloud networking, VPN access, DNS, firewalls, and connectivity, and diagnose network performance and availability issues.
Operate backup and disaster-recovery processes, verify backup integrity, test restoration procedures, and maintain recovery documentation and readiness.
Kubernetes, CI/CD, and Infrastructure as Code
Support Kubernetes environments across Amazon EKS, Google GKE, or Azure AKS, including cluster access, upgrades, troubleshooting, observability, and workload reliability.
Maintain CI/CD pipelines and Terraform-based infrastructure, applying controlled changes, reviewing failures, and improving repeatability across environments.
Systems Automation
Automate recurring administration, monitoring, reporting, provisioning, and remediation tasks using Bash or Python.
Build maintainable scripts with clear documentation, version control, logging, error handling, and appropriate testing and review.
Vulnerability, Endpoint, and Secrets Security
Run vulnerability-management activities, including scanning, triage, risk-based prioritization, remediation tracking, exception handling, and stakeholder reporting.
Administer EDR and secrets-management platforms, investigate alerts, enforce secure secret storage and rotation, and support incident response.
SOC 2 and ISO 27001 Audit Support
Collect, organize, and validate technical evidence for SOC 2 and ISO 27001 audits, including access, change, vulnerability, backup, and security-monitoring records.
Maintain audit-ready documentation, respond to evidence requests, identify control gaps, and work with control owners to complete remediation actions.
What We Are Looking For
Required Qualification
10+ years in sysadmin or infrastructure roles, including 3+ years in cloud
Strong Linux and networking skills
Hands-on experience with identity/SSO, MDM and SaaS administration
Working knowledge of Kubernetes, Docker, Terraform and CI/CD
Practical security skills: IAM, patching, vulnerability scanning
Nice to Have
RHCE, CKA or cloud certifications; startup experience.
Important Logistical Note
Candidates must possess active, valid US work authorization. Quilr is currently unable to provide visa sponsorship.
