Site Reliability Engineer

Hadrian is building autonomous factories to reindustrialize America. By combining AI, advanced software, robotics, and full-stack manufacturing, we help aerospace and defense companies build rockets, satellites, aircraft, ships, and other mission-critical systems up to 10x faster and at significantly lower cost.

Following our $1.37B Series D at a $7.87B valuation, Hadrian is rapidly expanding our manufacturing footprint, launching new capabilities across welding, casting, forging, electronics, additive manufacturing, and more, while scaling our Factory-as-a-Service platform to transform how critical products are built.

Backed by leading investors including JPMorgan Chase, Valor Equity Partners, Andreessen Horowitz, Founders Fund, 137 Ventures, Lux Capital, T. Rowe Price, and Morgan Stanley, we’re building the future of American manufacturing—and looking for exceptional people to help make it happen.

If you’re ready to take on the most challenging and rewarding work of your career while helping create American manufacturing jobs for generations to come, you’re exactly who we’re looking for.

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.

What We’re Looking For

• 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.

Compensation

For this role, the target salary range is $175,000 - $285,000 (actual range may vary based on experience).

This is the lowest to highest salary we reasonably and in good faith believe we would pay for this role at the time of this posting. We may ultimately pay more or less than the posted range, and the range may be modified in the future. An employee's pay position within the salary range will be based on several factors, including, but not limited to, relevant education, qualifications, certifications, experience, skills, geographic location, performance, and business or organizational needs.
