Site Reliability Engineer, Client Platform

What You'll Do

• Focus on building scalable, automated solutions that ensure seamless deployments, security configurations, and efficient operational workflows for our end-users.
• Own, administer, and optimize MDM platforms (Fleet DM, Intune, Workspace ONE) to enforce configuration and drive self-healing by writing OS-level scripts and lightweight tools that resolve recurring user-impacting issues (disk pressure, certificate expiry, drift, broken agents) at the source instead of via tickets.
• Proactive Response. We want to gather telemetry data and analytics to develop an understanding of device lifecycles. We want to prevent end-user disruption by understanding when and how to act.
• Partner with Security, IT, and Infrastructure to translate compliance requirements (CMMC) into enforceable, code-managed baselines.
• Build dashboards and alerts that measure end-user experience as an SLO, not a helpdesk metric.

Do you have experience in Infrastructure as Code (IaC)?, * Ownership. You treat the fleet as a product, take incidents personally, and close the loop with automation rather than a runbook. Strong scripting in Python, Bash, and PowerShell.

• Scalability. Hands-on experience with Infrastructure as Code (IaC) and configuration management: Ansible and Terraform (or equivalents like Chef, Salt, Puppet, Pulumi).
• Device Management. Working knowledge of at least one major MDM (Fleet DM, Intune, Jamf, Workspace ONE) and its API surface.
• Security Remediation. Practical experience with patch management, vulnerability remediation, and endpoint hardening on both macOS and Windows.

What Will Set You Apart

• Strong computer science fundamentals. You can reason about systems from the operating system up, demonstrating durable and sustainable solutions.
• Experience building self-healing or auto-remediation platforms (remote actions, osquery + response, custom agents). Exposure to OT (Operational Technology) systems.
• Comfort operating in an SRE culture: SLOs, error budgets, and blameless postmortems applied to the end-user experience.

Hadrian is building autonomous factories that help aerospace and defense companies manufacture rockets, satellites, jets, and ships up to 10x faster and up to 2x cheaper. By combining advanced software, robotics, and full-stack manufacturing, we are reinventing how America produces its most critical parts. We're accelerating our mission with the launch of Factory 3 in Mesa, Arizona, a 290,000-square-foot facility creating 350 new jobs. We are expanding rapidly to support thousands of future hires, launching Hadrian Maritime to expand into naval production, and introducing a Factory-as-a-Service model that delivers complete systems instead of individual parts. Hadrian is backed by leading investors including T. Rowe Price, Lux Capital, Founders Fund, and Andreessen Horowitz, our fast-growing team is united around reindustrializing American manufacturing for the 21st century and beyond.
