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 challenges. This is a fielded-systems SRE role, distinct from traditional cloud SRE or product development. You will be the frontline for keeping deployed imaging systems operational. As the second SRE on a small, high-trust team reporting to the lead SRE, you will own the health and uptime of fielded systems end-to-end. Your responsibilities include triaging and diagnosing issues that may originate anywhere in the stack—networking, calibration, firmware, hardware, or services—and driving resolution. You will serve as the escalation point for field personnel and customer-support channels, acting as the deep-expertise backstop when issues bubble up from Tier 0 through Mission Success / Product Operations. Key responsibilities: - Own fielded system reliability and uptime; triage and resolve issues across system boundaries - Run point on escalations from support channels and customer-support pipeline - Build and maintain runbooks, diagnostics, and self-service tooling to reduce recurring problems - Hold the boundary with engineering: own everything short of code fixes; cleanly reproduce and document genuine software defects for handoff to Mission Software Engineers - Feed field reliability signals back into product design to improve observability, upgrade safety, and failure gracefully - Participate in structured on-call rotation, including after-hours and weekend coverage - Travel approximately 20% for field support and deployment windows The work is varied and often ambiguous. You might spend a morning triaging a networking failure at a remote deployment site, an afternoon walking a field operator through sensor calibration over the phone, and the remainder of the week hardening a runbook to prevent the same issue recurring. Success requires methodical diagnosis under pressure, proactive communication, and the ability to work across system boundaries with incomplete visibility. Requirements: - 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 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 qualifications: - Experience supporting fielded or deployed systems (not just development environments) - Experience with fielded hardware or sensor systems (EO/IR, optical, or similar), including sensor calibration familiarity - 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)
