Anduril Industries is seeking a Site Reliability Engineer to join the Imaging team, which builds and fields state-of-the-art camera and sensor systems deployed for U.S. and allied military security. This is a fielded-systems SRE role—not traditional cloud SRE and not product development. You will be the frontline for keeping deployed imaging systems operational, serving as the escalation point when field personnel and customer support encounter issues in live environments. You will be the second SRE on a small, high-trust team, working directly with the lead SRE with real opportunity to shape how Imaging reliability and support scale. The work is varied and often ambiguous: you might triage a networking failure at a remote deployment site one morning, walk a field operator through sensor calibration over the phone in the afternoon, and spend the rest of the week hardening runbooks to prevent recurring issues. When a fielded system misbehaves, the root cause could be anywhere in the stack—networking, calibration, upgrades, sensor hardware—and you own the diagnosis and resolution. Key responsibilities include: owning the health and uptime of deployed imaging systems; running point on escalations from support channels and customer-support pipelines as the deep-expertise backstop; converting recurring fires into durable runbooks, diagnostics, and self-service tooling; holding the boundary with engineering by owning everything short of a code fix and cleanly handing off genuine software defects; and feeding field reliability signals back into the product to improve observability, upgrade safety, and failure modes. Travel is expected approximately 20% of the time for field support and deployment windows. Success in this role requires closing loops and owning problems until resolved, staying calm under pressure when systems are down in the field, communicating proactively with status updates and documentation, being comfortable with ambiguity at stack boundaries and systematically narrowing down root causes, and knowing when an issue is a true code-level defect that belongs with engineering. REQUIREMENTS: Required: - 3+ years in SRE, DevOps, field/systems engineering, or production support of deployed hardware/software systems, with real ownership after systems ship (not just standing them up) - Strong Linux fundamentals, including comfort troubleshooting real networking issues (IP, routing, VPNs, connectivity in constrained or field environments) - Demonstrated ability to diagnose and resolve issues across system boundaries (networking, services, hardware interaction) without always having full visibility into every component - Comfortable owning a structured on-call rotation, including scheduled after-hours and weekend coverage - Strong written and verbal communication skills, including ability to run remote troubleshooting sessions with non-technical operators and document outcomes - Eligibility to obtain and maintain a U.S. Secret clearance Preferred: - Experience supporting fielded or deployed systems, not just development environments - Experience with fielded hardware or sensor systems (EO/IR, optical, or similar), including familiarity with sensor calibration - Scripting for diagnostics and automation (Python, Bash, or similar) - Familiarity with Nix or NixOS - Familiarity with systemd service management and observability practices on Linux - Familiarity with incident tooling (PagerDuty or equivalent)
