Mission Security Engineer III

Space is a warfighting domain. True Anomaly seeks those with the talent and ambition to build the technology that secures it.OUR MISSIONTrue Anomaly delivers decisive capabilities for space superiority. We build autonomous spacecraft, advanced payloads, mission software, and space-based interceptors — enabling the U.S. and its Allies to secure the space environment and counter threats from the ultimate high ground.OUR VALUESBe the offset. We create asymmetric advantages with creativity and ingenuity.What would it take? We challenge assumptions to deliver ambitious results.It’s the people. Our team is our competitive advantage and we are better together.YOUR MISSIONAs a Mission Security Engineer III, you will be a critical technical expert securing national security space systems, classified ground-based Command and Control (C2) infrastructure, and space vehicle hardware and software.This is a hands-on role that blends deep technical Information Technology (IT) expertise with cybersecurity and compliance acumen. We are looking for candidates with deep expertise in at least one of the following disciplines:Cybersecurity compliance (NIST 800-53 controls implementation and validation)DevSecOpsSoftware DevelopmentOperating systems & hosting (Windows / Linux)Cloud infrastructure deployment (AWS/Azure)Containerization infrastructure, Kubernetes, EKS, AKSBoundary protectionEndpoint Detection and Response / Extended Detection and Response (EDR/XDR)Security Information and Event Management / Security Operations Center (SIEM/SOC) deploymentYou will work as part of a highly capable, cross-functional team to design, deploy, measure, and document classified systems from the ground up — navigating dynamic, cross-program priorities that change daily. You will be responsible for ensuring our systems meet the most rigorous federal security standards while accelerating delivery of critical warfighting capabilities to Department of War and Intelligence Community customers.This is an ideal role for a security-focused technologist with deep IT or cybersecurity technical skills who is eager to take novel, innovative approaches to cybersecurity and compliance. If you're energized by the challenges of securing mission-critical systems that protect lives and national interests, join our team.ResponsibilitiesImplement end-to-end security controls for
