• Strategic Product Ownership: Act as the primary technical liaison between operational stakeholders and development teams, translating mission requirements into actionable, prioritized technical roadmaps that align with P.I. goals.

• Security Engineering Oversight: Serve as the Subject Matter Expert (SME) in defensive engineering and detection mechanics, guiding the integration of telemetry and validation environments to enhance offensive-cyber testing accuracy.

• Mentorship & Capability Development: Cultivate a culture of technical excellence by mentoring junior staff in low-level debugging, reverse engineering, and secure coding, while developing training curricula that bridge the gap between complex capability frameworks and end-user operational application.

• Operational Collaboration: Drive rapid triage and remediation efforts by collaborating across multi-disciplinary teams—including mission analysts and vulnerability researchers—to refine deployed capabilities and ensure strict alignment with evolving mission needs.

Minimum Qualifications:

• Bachelor’s Degree in Computer Science or a related technical field (e.g., Information Systems, Network Engineering) from an accredited college or university.

• Experience with automated testing and continuous integration (CI/CD) pipelines tailored for restricted software development environments

• Ability to explain complex technical requirements, systems architecture, and operational mission requirements to technical teams and non-technical leadership alike

• Ability to translate highly technical capability frameworks into digestible, impactful training curricula for customers spanning a wide spectrum of technical expertise

• Experience in low-level internals in one or more platforms (e.g., Windows, Unix, mobile, or network devices)
