Anduril Industries System Security Engineer, Space at Anduril Industries responsible for owning the security architecture of space systems. This includes deriving security requirements, designing protections for command and telemetry links, and verifying system security across spacecraft and ground segments.

Responsibilities

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

Qualification

Direct experience working with U$183

Required

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 with supply chain security as it applies to space or defense systems
Ability to make and defend engineering trade-offs where security competes with schedule, mass, power, or cost
Direct experience working with U.S. Government customers on classified or sensitive programs
Active security clearance (almost certainly TS/SCI given the "space programs" and government customer context, though the posting doesn't say explicitly)
Strong communication skills — you're the security voice in the room with program leadership and the customer, not writing reports from a back office
CCNP certification or equivalent advanced networking credential
