Our flagship product, the NodeZeroTM platform, delivers production-safe autonomous pentests and other key assessment operations that scale across the largest internal, external, cloud, and hybrid cloud environments. NodeZero has been adopted by organizations of all sizes, from small educational institutions to government agencies and Global 100 enterprises. It is used by ITOps/SecOps teams, consulting pentesters, and MSSPs and MSPs.\nWe are a fusion of former U.S. Special Operations cyber operators, startup engineers, and formerly frustrated cybersecurity practitioners. We're committed to helping solve our common security problems: ineffective security tools, false positives resulting in alert fatigue, blind spots, \"checkbox” security culture, cybersecurity skills shortage, and the long lead time and expense of hiring outside consultants. Collectively, we are a team of learn it alls, committed to a culture of respect, collaboration, ownership, and results.\nSummary/Overview\nAs we expand our offering to Federal and Defense customers, we are building dedicated, compliant environments that meet FedRAMP and DoD Impact Level 4/5 (IL4/IL5) requirements. We are hiring a Federal Security Engineering Manager to build and lead the team that maintains the security of those environments.\nThis is a founding leadership role and will be responsible for building the team, setting its direction, and holding it accountable for delivering secure cloud architecture, detection, and response for our federal boundaries. This role will recruit and develop a security engineering team, define what right looks like, remove obstacles, and represent the team to leadership and partner organizations.\nWhat You'll Do\nBuild and Lead the Federal Security Engineering Team\nRecruit, hire, and onboard a team of cloud, SIEM, and SOC security engineers dedicated to our FedRAMP and IL4/IL5 environments, including candidates who meet U.S.-person and clearance requirements.\n\nDefine the hiring roadmap, role profiles, interview loops, and sequencing for the team as the federal program scales.\n\nLead, coach, and develop security engineers through regular 1:1s, goal setting, feedback, and career growth. Recognize and retain high performers.\n\nSet priorities and operating rhythms that balance strategic investments, day-to-day engineering support, and incident response.\n\nLead horizontally with peers in commercial and partner teams.\n\nLead Federal Cloud Security Engineering\nSet the technical direction for how the team secures our federal cloud environments, including identity and access, network segmentation, encryption and key management, hardening baselines, and logging.\n\nEnsure cloud security engineers design and implement controls that meet FedRAMP and DoD Cloud Computing SRG requirements, and that those controls are automated through Infrastructure as Code and policy-as-code.\n\nReview and approve team architecture decisions, threat models, and risk assessments for federal deployments and new features.\n\nPartner with Engineering to embed security into the SDLC and CI/CD pipelines for federal workloads.\n\nSet standards for identity and access management in federal environments, including least privilege, federated identity, and privileged access.\n\nLead Federal Detection and Response\nDefine the vision and roadmap for SIEM, log aggregation, and detection within the federal boundary, and ensure the team's work satisfies audit-logging and retention requirements.\n\nBuild the SOC function for the federal environment: establish functional requirements, operating model, on-call structure, escalation paths, and documentation standards.\n\nDrive an automation-first culture, guiding the team toward SOAR and AI/ML-assisted triage, investigation, and response.\n\nDirect the development of detection content and threat hunting aligned to MITRE ATT&CK, and use internal pentests and purple-team exercises to steer improvements.\n\nServe as the accountable leader for security incident response in the federal environments, including escalation, coordination across teams, post-incident review, and required customer and government incident reporting.\n\nCommunicate, Measure, and Manage\nDefine team metrics (e.g., MTTD/MTTR, detection coverage, false-positive rates, control and tooling health) and report on posture, risk, and priorities to leadership and federal stakeholders.\n\nOwn the team's budget, tooling strategy, and vendor relationships, including selection of FedRAMP-authorized and IL-appropriate tools.\n\nDevelop and maintain the team's security standards, SOPs, and engineering practices, aligned to NIST 800-53/800-171, FedRAMP, the DoD SRG, CIS, and MITRE ATT&CK.\n\nEvaluate and recommend new tools, techniques, and controls to improve security posture within federal constraints.\n\nStay current on emerging threats and federal security requirements, and translate them into team priorities.\n\nWhat You'll Bring\nRequired\nU.S. citizenship and the ability to meet DoD personnel security requirements for IL4/IL5 environments. The ability to obtain and maintain a U.S. government security clearance is required.\n\n8+ years of experience in cybersecurity, including 5+ years in cloud security (AWS strongly preferred).\n\n3+ years of experience managing or technically leading security engineers, with a track record of hiring, developing, and retaining strong talent.\n\nExperience building and scaling a security engineering team\n\nWorking knowledge of how FedRAMP High and DoD IL4/IL5 requirements shape cloud architecture, logging, and incident response, sufficient to guide engineers building to those standards.\n\nStrong technical foundation in cloud security architecture, IAM, encryption and key management, network security, secure SDLC, and Infrastructure as Code, sufficient to review designs and make sound technical decisions.\n\nFamiliarity with SIEM and detection engineering concepts and with SOC operating models, including incident response and automation.\n\nExcellent written and verbal communication, including explaining technical risk and tradeoffs to engineers, executives, and government stakeholders.\n\nBachelor's degree in Computer Science, Cybersecurity, Information Systems, or a related field, or equivalent practical experience.\n\nTechnology Context\nCloud: AWS GovCloud, Kubernetes and container security\n\nIaC / CI/CD: Crossplane, GitLab, ArgoCD\n\nSIEM / SOAR: ELK Stack, AWS GuardDuty\n\nDetection: Sigma, YARA, MITRE ATT&CK, EDR/XDR\n\nHardening and Scanning: STIG/SCAP, CIS benchmarks, cloud posture management\n\nPreferred\nExperience standing up security capabilities for a SaaS product entering the federal market.\n\nPrior experience operating within FedRAMP or DoD IL4/IL5 environments, in a hands-on or leadership capacity.\n\nBackground in incident management, detection engineering, or logs/events processing.\n\nExperience with SOC build-out and scaling in a high-growth company.\n\nActive clearance.\n\nCertifications such as CISSP, CISM, CCSP, AWS Certified Security - Specialty, GCIH/GCIA, or similar.\n\nWho You Are\nA Team Builder: You have created teams, not just inherited them.
