Cybersecurity Engineer, Senior Manager

Two Six Technologies is seeking a visionary Cybersecurity Engineer, Senior Manager to architect, build, and defend the highly secure environments that power our advanced R&D initiatives. We are looking for a true security architect who can seamlessly bridge the gap between rigorous government security frameworks (NIST, STIGs, CMMC) and complex operational engineering. In this role, you will lead the strategic design of our secure infrastructure, guide DevSecOps integration across software projects, and engineer pragmatic, intent-based security solutions. If you excel at deconflicting stringent compliance mandates with real-world engineering challenges, and thrive in a role that spans infrastructure defense, network architecture, and application security, we want you to lead our team.

Preferable locations are San Antonio TX and Arlington VA. The role is considered hybrid, and would require at least 3 days a week in the office at either location.

Key Responsibilities

• Strategic Security Architecture: Architect custom security solutions that deconflict stringent government compliance requirements with critical operational needs. Move beyond standard "box checking" to design risk-optimized, tailored controls.
• Intent-Based Engineering: Engineer alternative technical solutions when literal remediation causes operational failure. Leverage deep system knowledge and industry best practices to meet the core security intent of a framework while maintaining system functionality.
• Design & Implementation: Lead the hands-on technical development, configuration, and deployment of secure IT infrastructure and custom security tools, ensuring all architectures are defensible during an audit.
• Threat Defense & Mitigation Strategy: Develop high-level strategies, playbooks, and architectures for threat detection and incident response. Oversee the vulnerability mitigation lifecycle, guiding the team's efforts so that day-to-day monitoring is handled by staff while the Lead focuses on proactive, structural defense improvements.
• Collaborative Security: Partner with development and IT teams to seamlessly integrate security and compliance into CI/CD pipelines and software development lifecycles while supporting innovation.
• Team Leadership & Mentorship: Direct a small team of security professionals across multiple projects. Mentor junior team members on how to balance strict compliance auditing with pragmatic, operational engineering solutions.

Required Skills & Qualifications
