Nix or NixOS is what we use and what we most want to see; adjacent depth in Bazel, Buildroot, Yocto, or infrastructure-as-code tooling (Terraform, Ansible, Pulumi) is a solid substitute. * Proficiency in Rust or C++, enough to read and modify the services that sit on top of the platform, not just the configuration that deploys them. * Comfort operating and troubleshooting real hardware: serial consoles, provisioning and reflashing, boot problems, and remote debugging of systems you cannot physically reach. * Demonstrated ability to define a technical interface that other teams build against, and to hold that line through code review and documentation rather than authority. * US person status required, with eligibility to obtain and maintain a US security clearance. NICE TO HAVE * Hands-on NixOS experience, including writing modules and maintaining flakes. * Python for tooling and automation. * Experience with NVIDIA Jetson platforms (Xavier, Orin, Thor) including BSP integration, device trees, and JetPack upgrades. * Fleet-scale operational experience: over-the-air update systems, observability pipelines, or long-lived embedded deployments. * Familiarity with CAN, SNMP, or managed-switch configuration in an embedded context. * Experience setting up and maintaining CI/CD for large build graphs and hardware-in-the-loop pipelines. ## Description * Own the shared base of our NixOS overlay: system modules, compute platform definitions, common tower services, and the image definitions that every product variant composes from. * Own the tower network topology end to end: VLAN and subnet allocation, bridging, link ranking and failover across heterogeneous backhaul, NAT and firewall policy, and the physical-port-to-payload mapping for each carrier board. * Define and enforce the integration contract that business line teams use to add network-attached payloads, so their additions extend the platform instead of diverging from it. * Drive the consolidation of legacy, per-product configurations into the common overlay, with build-time checks that keep them from drifting back apart. * Support and extend our real-time messaging layer as services migrate from the legacy pub-sub bus to its next-generation replacement, including the topic and schema contracts that define who owns which data. * Debug problems that cross every layer at once: kernel and device tree, systemd unit ordering, Nix evaluation, link-layer configuration, and the sensor daemons on top., To ensure your safety and help you navigate your job search with confidence, please keep the following critical points in mind: * No Financial Requests: Anduril will never solicit payment or demand personal financial details (such as banking information, credit card numbers, or social security numbers) at any stage of our hiring process.

If you suspect any suspicious activity, please verify the agency's authenticity by reaching out to contact@anduril.com. * Exercise Caution with Unsolicited Outreach: If you receive any communication that appears suspicious, contains grammatical errors, or makes unusual requests, do not engage. Always confirm the sender's email domain is @anduril.com before providing any personal information or clicking on links. * What to Do If You Suspect Fraud: Should you encounter any questionable or fraudulent outreach claiming to be from Anduril, please report it immediately to contact@anduril.com. Your proactive caution is invaluable in protecting your personal information and upholding the security and trustworthiness of our recruitment efforts.
