Anduril Industries is a defense technology company transforming U.S. and allied military capabilities through advanced technology, including AI-powered operating systems, autonomy, computer vision, and sensor fusion. The Imaging team builds and fields state-of-the-art camera and sensor systems deployed to solve real security challenges. This Site Reliability Engineer role is the second SRE on a small, high-trust team, working directly with the lead SRE to keep fielded imaging systems alive in production. You will be the frontline for deployed system reliability and the escalation point when field personnel and customer support encounter issues. The work is varied and often ambiguous: you might triage a networking failure at a remote deployment site, walk a field operator through sensor calibration over the phone, or harden runbooks to prevent recurring issues. When a fielded system misbehaves, the root cause could be anywhere in the stack—hardware, firmware, networking, services, or cloud integrations—and you are responsible for narrowing it down systematically. Key responsibilities include: - Own the health and uptime of deployed imaging systems, triaging and driving resolution of issues across the full stack - Run point on escalations from support channels and customer-support pipelines, acting as the deep-expertise backstop - Build and maintain runbooks, diagnostics, and self-service tooling to reduce repeat problems and shrink support load - Own everything short of a code fix; when an issue is a genuine software defect, cleanly reproduce and document it for handoff to Mission Software Engineers - Feed field reliability signals back into the product to improve observability, upgrade safety, and failure gracefully - Participate in structured on-call rotation, including after-hours and weekend coverage - Travel approximately 20% of the time for field support and deployment windows Success in this role requires closing loops (owning problems until resolved), staying calm under pressure, communicating proactively, being comfortable with ambiguity at stack boundaries, and knowing when to hand off to 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 - 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)
