Anduril Industries, Inc.; Costa Mesa (CA); On-site; USD 150,000 - 210,000; Full time

Job summary

Anduril Industries in Costa Mesa develops defense technology and leads space-focused security programs. We seek a Systems Security Engineer to own the security architecture across space, ground, and link segments, coordinating with flight software, avionics, RF/comms, and government customers.

You will translate threat intelligence into concrete design decisions, define secure boot and data protection foundations, and drive verification across all integration stages.

Qualifications

• Experience designing security architectures for complex, multi-segment systems.
• Ability to translate threat intelligence into concrete design decisions.
• Experience collaborating across flight software, avionics, RF/comms, and ground systems.

Responsibilities

• Own end-to-end security architecture across space, ground, link, and user segments.
• Derive security requirements from customer needs, threat assessments, and policy.
• Design protections for command and telemetry links, including authentication and encryption.
• Define onboard security foundation: secure boot, hardware root of trust, firmware integrity.
• Build and maintain threat models and attack trees for the full mission.
• Collaborate with subsystem REs to implement security requirements.
• Run security verification at integration levels.
• Coordinate with red teams and assessment teams to identify weaknesses.
• Assess supplier hardware and software for supply chain risk.
• Brief architectures to Government customers and program leadership.
• Help build reusable security patterns and tooling.

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

Anduril's Space team is dedicated to expanding our AI-powered capabilities into the final frontier, enhancing Space Domain Awareness, Space Control, and Command and Control for U.S. military and allied partners. We're developing fully integrated hardware and software systems, including Lattice for Space Missions and modular payloads, to address growing threats in space and ensure our Guardians maintain a decisive advantage in this contested warfighting domain.

ABOUT THE JOB

We're hiring a Systems Security Engineer to own that architecture. You'll be the technical security authority on one or more space programs. You'll work directly with subsystem Responsible Engineers (REs) across flight software, avionics, RF/comms, and ground, and with Government customers, to make sure each system holds up against real threats and can prove it at every milestone.

This is an engineering role, not a compliance role. You won't run RMF paperwork or administer accreditation packages; we have ISSOs and ISSMs for that, and you'll partner with them closely. Your job is to make the system secure. Theirs is to show it.You'll take a program from customer need to on-orbit operations. You'll turn threat intelligence and mission requirements into a security architecture, break that architecture down into requirements each subsystem team can build to, and verify that what gets built matches what was designed. Your work covers the whole system: the spacecraft bus, the payload, the command and telemetry links, the ground segment, and the supply chain behind all of them.You'll have real ownership and a direct line to program leadership and the customer. When a trade comes up between security, schedule, mass, power, or cost, you'll be in the room making the call.

WHAT YOU'LL DO

• Own the end-to-end security architecture for assigned space systems, across the space, ground, link, and user segments
• Derive security requirements from customer needs, threat assessments, and applicable space security policy, then flow them down to subsystem specifications
• Design protections for command and telemetry links, including authentication, encryption, anti-replay, and key management approaches
• Define the onboard security foundation: secure boot, hardware root of trust, firmware and software integrity, memory protection, and secure update paths for systems that can't be physically touched after launch
• Build and maintain threat models and attack trees for the full mission, and use them to drive design decisions
• Partner with flight software, avionics, RF, and ground REs to turn security requirements into working implementations, then review designs and code against them
• Develop and run security verification at every integration level: unit, subsystem, flatsat, spacecraft, and end-to-end with the ground segment
• Work with internal and external red teams and assessment teams to find weaknesses in our products and integrated third-party components, then drive fixes to closure
• Assess supplier hardware and software for supply chain risk and set the security requirements we put on vendors
• Own the security content at major milestones: SRR, PDR, CDR, TRR, and PSR
• Brief security architectures to Government customers, program leadership, and technical reviewers, adjusting the depth for each audience
• Partner with ISSOs and ISSMs so design decisions support accreditation instead of fighting it late in the program
• Help build out reusable security patterns, reference architectures, and tooling across Anduril's space programs

REQUIREMENTS

• Experience designing security architectures for complex, multi-segment systems (spacecraft bus, payload, ground segment, RF/comms links)
• Ability to decompose system-level security architecture into subsystem-level requirements that engineering teams can actually build and test against
• Hands-on understanding of threat modeling and the ability to translate threat intelligence into concrete design decisions
• Experience working across disciplines - flight software, avionics, RF/comms, ground systems - and enough technical depth in each to hold your own with the subsystem REs
• Familiarity with the full system lifecycle from requirements through verification and on-orbit operations
• Experience
