Role
Who you are
- You are an experienced security leader who understands that strong enterprise security comes from enforceable baselines, high-quality monitoring, and thoughtful automation
- You’ve led technical security teams and know how to create clarity around ownership, detection coverage, configuration standards, and measurable outcomes. You’re comfortable improving processes, reviewing architectures, and making risk-based decisions about security controls
- You think holistically about enterprise security—understanding how endpoint security, identity, SaaS configuration, vulnerability management, and monitoring work together to support a resilient security program
- You value structure, accountability, and continuous improvement, and you ensure security operations and engineering outputs remain reliable, measurable, and audit-ready
- 7–10+ years of experience in security engineering, security operations, or enterprise security architecture
- 2+ years leading technical security teams
- Experience with SIEM, EDR, and enterprise monitoring platforms
- Experience implementing security configuration baselines aligned with frameworks such as NIST 800-53, CMMC 2.0, or DISA STIGs
- Experience overseeing vulnerability management programs and remediation SLAs
- Strong understanding of enterprise logging across endpoints, identity providers, SaaS platforms, and cloud systems
- Strong understanding of API connections and workflow automations
- Experience with endpoint security tooling (e.g., MDM platforms, browser management, secure web gateways)
- Experience defining and reporting security operations metrics (e.g., MTTD, MTTR, detection coverage)
- Ability to translate regulatory requirements into enforceable technical controls
- Strong collaboration and communication skills with the ability to present clear security insights to leadership
What the job involves
- We’re hiring a Corporate Security Manager to lead our Corporate Security Engineering and Security Operations functions
- This role is responsible for strengthening the security posture of our Corporate IT environment and commercial infrastructure
- Reporting to the Director of Corporate IT & Security, you will partner closely with Corporate IT, GRC, Engineering, and application owners to ensure systems are securely configured, continuously monitored, and aligned to regulatory frameworks such as CMMC 2.0 and NIST 800-53
- This role combines technical security leadership with program ownership across configuration standards, vulnerability management, SaaS security governance, monitoring strategy, and detection engineering
- You’ll lead a team of engineers and analysts while driving improvements in automation, monitoring coverage, and operational maturity
- Own the strategy and maturity roadmap for corporate security engineering and operations. Define standards for configuration baselines, logging and telemetry, detection coverage, vulnerability remediation, and security automation
- Manage and develop System Security Engineers and Security Operations Analysts. Provide coaching, remove blockers, and focus the team on high-impact risk reduction
- Strengthen configuration enforcement, vulnerability remediation, monitoring quality, and detection coverage across endpoints, identity systems, SaaS platforms, and enterprise infrastructure
- Collaborate with IT, Engineering, Security, and Compliance teams to ensure systems are deployed securely, monitoring supports operational risk management, and security controls align with regulatory commitments
- Establish consistent processes for monitoring reviews, vulnerability remediation tracking, detection improvements, incident support, and audit evidence management
Our take
Onebrief is transforming military planning with its software platform, which simplifies and speeds up operational tasks for US military headquarters worldwide. The platform enhances decision-making and streamlines complex planning, supporting various missions from defense to humanitarian aid.
The company has continuously updated its offering, for example by launching an API for better integration with other military tools, and developing offline access for remote use. It has also added AI features as part of continued innovation to meet the evolving needs of military users.
Onebrief has secured substantial funding which has allowed it to grow significantly. The latest round, secured in early 2026, will support rapid scaling and comes alongside the company's acquisition of Battle Road Digital, a leading defense innovation company applying gaming technology to defense and national security challenges.
