Job description

Anduril Industries is a defense technology company with a mission to transform U.S. and allied military capabilities with advanced technology. By bringing the expertise, technology, and business model of the 21st century’s most innovative companies to the defense industry, Anduril is changing how military systems are designed, built and sold. Anduril’s family of systems is powered by Lattice OS, an AI-powered operating system that turns thousands of data streams into a realtime, 3D command and control center. As the world enters an era of strategic competition, Anduril is committed to bringing cutting-edge autonomy, AI, computer vision, sensor fusion, and networking technology to the military in months, not years.

About The Team

The Sentry Tower Software team develops robotic systems that provide force protection capabilities, monitoring the perimeter of secure areas, land or sea, for approaching people, vehicles, and vessels. We live in a world where security officers are increasingly overwhelmed by sensor data feeds. Our products leverage advanced sensor fusion and autonomy to seamlessly render activity in the environment to Lattice’s common operating picture.

About the Job

Sentry Towers are deployed to secure perimeters, some in contexts where the tower itself is a sensitive asset and physical access by an adversary is a realistic threat. That makes product security a hardware-and-software problem, not a policy exercise: if someone can pull a drive, attach a serial cable, plug in USB, or interrupt the bootloader, the design has to hold. We’re hiring a Senior Software Engineer to own product security for the tower platform.

You’ll own the trusted boot chain top to bottom, on NVIDIA Jetson compute across several generations. That means signed firmware and bootloaders, UEFI Secure Boot, signed kernel images, encrypted root filesystems, and the key management that makes it real: hardware-security-module-backed signing keys, separate development and production trust roots, and the release pipeline that signs what we ship.

Alongside the boot chain, you’ll own runtime hardening posture: what’s exposed on the network, what privileges the operator account holds, which physical interfaces are live in the field versus on a lab bench, and how a fielded fleet gets security patches on hardware whose vendor support is ending. You’ll work closely with our internal product security organization, translating requirements into implementations that ship, and reviewing our design decisions early, while they are still cheap to change.

Two things about this role are worth saying plainly. Security work is often the work of saying no, or of saying “not like that”, to engineers under schedule pressure who are not wrong to want to move faster; doing that well without becoming an obstacle is most of the craft. And the feedback loop is slow by construction: signed images cannot be built on your laptop, so the build farm is the gate, and you will wait on it. Some of the job is also inherited rather than chosen, including hardware whose vendor support is ending on a fixed date that will not move for us.

WHAT YOU’LL DO

• Own the signed boot chain across compute generations: firmware and bootloader signing, UEFI Secure Boot key hierarchies, signed kernel and initrd, and full-disk encryption with automated unlock.

• Own signing key management and the infrastructure behind it: HSM-backed keys, separation of development and production trust roots, key rotation, and build-time enforcement that the right keys sign the right artifacts.

• Define and implement the platform’s hardening postures, spanning network exposure and firewall policy, privilege and sudo restriction, serial console and USB lockdown, and the difference between a locked-down fielded system and a debuggable bench unit.

• Drive vulnerability management for the fielded fleet: track CVEs (Common Vulnerabilities and Exposures) against our kernel and userspace, own the patching strategy for hardware approaching vendor end-of-life, and keep a clear picture of fleet security state.

• Partner with our product security organization to turn security requirements into shippable implementations, act as our team’s security liaison, and support program-specific accreditation efforts.

REQUIRED QUALIFICATIONS

• 4+ years of professional software engineering with a security focus on Linux or embedded systems.

• Hands-on experience implementing a secure boot chain: code signing, chain of trust, UEFI Secure Boot or an equivalent vendor secure boot implementation.

• Practical cryptographic engineering skills: PKI and certificate hierarchies, HSM or PKCS#11-backed signing, key lifecycle management, and full-disk encryption.

• Strong Linux internals knowledge, particularly in patching, boot flow, kernel and initrd, systemd, privilege boundaries, and filesystem and device access control.

• Proficiency in C or Rust, plus the ability to w
