At a glance

The Imaging team builds and fields state-of-the-art camera and sensor systems deployed to solve real security challenges for the United States and its allies.
As a Site Reliability Engineer on the Imaging team, you are the frontline for keeping fielded imaging systems alive and acting as the escalation point when a deployed system is not behaving.
This is not a product development role or a traditional cloud-SRE role, but rather an opportunity to own fielded system reliability and ensure operational uptime.

Own fielded system reliability by triaging, diagnosing, and driving resolution for issues across the network, calibration, upgrades, or sensor hardware.
Run point on escalations as the first and second line of response for issues coming through support channels and customer-support pipelines.
Build and maintain runbooks, diagnostics, and self-service tooling that reduce repeat problems and shrink support load over time.
Hold the boundary with engineering by cleanly reproducing, documenting, and handing off genuine software defects to Mission Software Engineers.
Feed reliability back into the product by turning field lessons into signals that improve observability, upgrade safety, and failure graceful handling.
Travel approximately 20% of the time for field support and deployment windows.

3+ years in SRE, DevOps, field/systems engineering, or production support of deployed hardware/software systems with real ownership after shipping.
Strong Linux fundamentals, including comfort troubleshooting real networking issues such as IP, routing, VPNs, and connectivity in constrained or field environments.
Demonstrated ability to diagnose and resolve issues across system boundaries like networking, services, and hardware interaction without 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 the ability to run remote troubleshooting sessions with non-technical operators and document events.
Eligibility to obtain and maintain a U.S. Secret clearance.

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 such as PagerDuty or equivalent.
