About the Company General Matter enriches uranium. We are designing, building, and operating the world’s lowest-cost enrichment services, here in the US. In the process, we are restoring America’s ability to produce nuclear fuel to power AI, advanced manufacturing and critical industries our country relies on to remain competitive. Fuel drives the cost of advanced reactor electricity production, and enrichment drives the cost of the fuel that advanced reactors consume. Reliable, low-cost enrichment is the catalyst for the nuclear Renaissance now under way. Our mission is to make nuclear not only the cleanest and safest source of baseload power, but also the most affordable. We believe abundant nuclear energy will lead to a post-scarcity society. We were incubated inside Founders Fund, like Anduril and Palantir before us, and are backed by over a dozen of the world's top venture capital firms. Our lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production. We are a mission-driven company with a culture of urgency, accountability, and transparency. Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable. About This Role As a General Matter Security Engineer, you will play a critical role in protecting the systems, infrastructure, and information that enable our mission.

If you thrive in high-impact environments, enjoy solving complex security challenges, and are excited to help build secure systems from the ground up in a fast-paced, Skunkworks-style organization, we encourage you to join our team. Responsibilities Design, implement, and maintain security controls across product, infrastructure, corporate, and regulated environments. Secure cloud, on-prem, air-gapped, and classified systems in alignment with NRC, federal, and internal security requirements. Support security operations, including monitoring, detection engineering, incident response, vulnerability management, and remediation tracking. Implement and improve identity and access management controls across workforce systems, production environments, and privileged access workflows. Partner with engineering teams to embed application security and secure SDLC practices across hardware, firmware, and software development. Contribute to GRC efforts, including policy implementation, risk assessments, audit readiness, NRC licensing support, and classified facility accreditation preparation. Basic Qualifications 5+ years of hands-on cybersecurity experience across infrastructure, product, cloud, or security operations domains. Practical experience implementing security controls in production or high-stakes environments. Experience working in regulated environments such as federal, defense, nuclear, classified, ITAR, or similarly controlled settings. Strong technical knowledge of cloud security, network security, endpoint security, IAM, and security monitoring. Experience supporting incident response, vulnerability management, or security event investigation in operational environments. Ability to work cross-functionally with engineering, IT, compliance, and operations teams to drive security improvements. Preferred Skills and Experience Experience supporting NRC licensing, classified facility buildouts, or federal frameworks such as NIST 800-53, NIST 800-171, RMF, or STIGs. Familiarity with hardware security, embedded systems, industrial control systems, or operational technology environments. Experience designing or operating secure architectures for hybrid cloud, air-gapped, or highly restricted systems.
