Transform technology into opportunity as a Cybersecurity Engineer Senior Principal with GDIT. A career in enterprise IT means connecting and enhancing the systems that matter most.

The Intel and Homeland Security (IHS) Chief Technology Office (CTO) is responsible for technical solutioning with excellence within the division. The Cybersecurity Engineer Senior Principal role provides deep, hands-on cyber engineering expertise and advanced development skills to address our customers’ most complex challenges. The role focuses on building, prototyping, and delivering cutting-edge cyber capabilities and providing thought leadership that strengthens our mission outcomes.  

This role reports directly to the CTO Leadership and serves as a primary technical driver within high-impact cyber initiatives.

How a Cybersecurity Engineer Senior Principal will make an impact:

Cyber and Technical:

• Designs, develops, and evaluates complex cyber systems and capabilities, with emphasis on mission-driver cyber effects and risk-informed engineering
• Conducts hands-on software development and systems engineering, including prototyping and research, to develop new or enhanced cyber capabilities
• Performs in-depth technical research to identify vulnerabilities, characterize system behaviors, and inform offensive and defensive mission approaches
• Apply deep expertise in full spectrum cyber functional areas (OCO, DCO) to shame mission execution, capability development, and proposal solutions.
• Lead and contribute to the testing, validation, deployment, and sustainment of cyber tools, infrastructure, and mission systems.
• Develop and assess cyber‑related engineering artifacts—including system designs, dataflows, and software components—to anticipate and address operational cyber considerations.
• Develop automations, tooling, and software capabilities that support offensive or defensive missions across diverse environments and enterprises.

Innovation and Technical Leadership:

• Serve as a senior technical authority in shaping concepts, prototypes, and engineering approaches for mission‑aligned cyber capabilities.
• Identify and develop innovative technical solutions that meet emerging customer needs, leveraging deep cyber tradecraft and modern engineering practices.
• Conduct trade studies, analyze alternatives, and recommend technical paths that balance mission impact, feasibility, and resources.
• Collaborate with program teams to improve cybersecurity operations, advance capability deployment, and mentor engineers in advanced cyber techniques.
• Reviewing and providing constructive feedback on proposal and technical artifacts (designs, prototypes, research outputs, etc), ensuring alignment with mission and organizational goals.

• Contribute to Internal Research and Development (IRAD) efforts through hands-on architecture, design, prototyping and delivery.

The candidate must possess the following skills:

• Significant hands-on experience (minimum 3+ years each) in at least three of the following criteria:• Vulnerability analysis, security automation, or cyber-enabled data workflows (OCO)
• Threat analysis, incident response, and cyber mission planning (DCO)
• Operational support to Full Spectrum Cyber or joint cyber operations
• Enterprise or cloud security engineering

• Experience leading or contributing to R&D activities
• Experience across the full systems engineering lifecycle including trade studies, analysis of alternatives, prototype development, and operational pilots
• Proven ability to lead development of technical artifacts and engineering documentation such as security architecture diagrams, CONOPS, OV-1s, APIs and system descriptions
• Excellent verbal and written communication (including executive level interface), work autonomously and in groups, highly organized, deadline-oriented, continuous-improvement mindset.
• Functional understanding of U.S.  Government cyber authorities, operational frameworks, and how cyber, intelligence, and mission planning integrate to achieve outcomes
• Education: Bachelor of Science or advanced degree in a relevant technical field or equivalent work experience.
• Required Experience: 10+ years of related cyber, systems engineering, or mission-focused technical leadership experience, including at least 5 years leading technical aspects of cyber, cloud, or integrated mission systems.
• U.S. Citizenship is required.
• Requires a TS/SCI with the ability to achieve TS/SCI with polygraph

The likely salary range for this position is $170,000 - $230,000. This is not, however, a guarantee of compensation or salary. Rather, salary will be set based on experience, geographic location and possibly contractual requirements and could fall outside of this range.
