Systems Security Engineer

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., * 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, 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. Our legitimate recruitment is entirely free for candidates.
• Please always verify communications:
• Direct from Anduril: If you receive an email from one of our recruiters, it will only come from an @anduril.com address.
• Via Agency Partner: If contacted by a recruiting agency for an Anduril role, their email will clearly identify their agency. 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.

• 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
