What You Will Do

The Product Cybersecurity Center (PCsC) provides enterprise-wide services, enablers, training, and technical expertise that help RTX securely design, build, and assess the cybersecurity of its products. As a senior cybersecurity expert within this organization, the Sr. Principal Engineer, Cyber Vulnerability Assessment leads a broad range of product-focused security assessment activities—including vulnerability analysis, penetration testing, secure-design evaluation, and architectural review—to identify risks and strengthen the resilience of a broad range of RTX products across all lifecycle stages.

This role encompasses advanced vulnerability identification, penetration testing, secure design evaluation, architectural analysis, and risk assessment — all aimed at strengthening the cybersecurity posture and resilience of RTX products. It requires deep technical capability, strong analytical skills, and the ability to provide actionable recommendations that directly influence product engineering decisions.

A key component of this role is also the development and delivery of cybersecurity training that enables product teams to integrate secure practices into design, development, testing, and sustainment. The Sr. Principal Engineer ensures that assessment insights and real-world findings directly shape course content, hands-on exercises, and learning materials used across RTX engineering teams. Training is not an isolated task; it is a strategic capability that amplifies the impact of assessment activities by raising the overall cybersecurity proficiency of the product engineering workforce.

This is an individual contributor role with no direct reports, but it requires operating as a recognized technical leader. The Sr. Principal Engineer will regularly lead assessment teams composed of engineers and specialists from across the business, providing technical direction, mentoring, and coordinating activity to deliver high-impact product assessments. Influence, expertise, and the ability to guide others—without formal authority—are essential for success.

Key Responsibilities

Holistic Product Cybersecurity Assessment

• Conduct comprehensive cybersecurity evaluations of RTX products across embedded systems, mission systems, avionics, space platforms, hardware/software integrated systems, and cloud-connected components.

• Assess product attack surfaces, interfaces, workflows, and security controls to identify weaknesses that could impact mission performance, safety, or resilience.

• Perform system-level risk assessments and deliver prioritized mitigation recommendations tailored to product requirements and operational environments.

• Review and analyze design artifacts, system behaviors, interface specifications, and product architectures to identify potential vulnerabilities or insecure implementation choices.

Vulnerability Analysis & Penetration Testing

• Plan, execute, and lead advanced vulnerability analysis and penetration testing activities as part of end‑to‑end product cybersecurity assessments.

• Validate vulnerabilities and test exploitation feasibility across software, hardware, network, and physical attack surfaces across a broad range to RTX technologies – including both traditional IT systems and embedded systems.
