Application Engineer, Cyber Security

About the Role

The Sr. Application Engineer, Cyber Security is a security-focused software engineer responsible for designing, building, and automating security controls directly into application architectures, CI/CD pipelines, and software development workflows. This individual identifies weaknesses in the security posture within the application or web space and defines methods to achieve security control requirements via automation or highly efficient means that support timely delivery with minimal overhead.

They work across internal and external teams of infrastructure specialists and software engineers to ensure services are delivered and used securely, offering advice and guidance on security decisions and ensuring the effective use of common tools and patterns. The role requires a collaborative, service-oriented mentality, a high sense of ownership, and a strong track record of driving security initiatives to completion.

Responsibilities

• Be the primary security expert for multiple product lines and act as the point of contact for engineering and security.
• Design, write, and maintain custom security tools, automation scripts, and custom scanner rules to streamline security checks in CI/CD pipelines.
• Partner directly with software developers at the code level—providing actionable code snippets, refactoring recommendations, and technical architectural patterns to remediate complex vulnerabilities.
• Support engineering with implementing security fixes, ensuring security scanners are utilized correctly, and develop strategies to proactively secure their architecture.
• Review development frameworks for security functionality, consistency, and uplift opportunities.
• Perform threat modeling sessions and leverage them to prioritize time based on risk impact.
• Implement and/or assess existing security controls.
• Produce detailed technical designs and document all work using required standards, methods, and tools, including prototyping tools where appropriate.
• Design systems characterized by managed levels of risk, manageable business and technical complexity, and meaningful impact; works with well-understood technology and identifies appropriate patterns.
• Work with application development teams to ensure secure software development lifecycle (S-SDLC) implementation and validation.
• Educate and train product teams.
• Evaluate client needs, coordinate design for a solution, and clearly communicate the value proposition of complex and highly technical cyber security subjects.
