Application Security Coordinator - Threat Modeling

Responsibilities:

Threat Modeling & Secure Design Coordination

• Provide programmatic support and coordination for application and infrastructure security assessments.
• Own and manage the threat modeling engagement from intake through final reporting and closure.
• Coordinate workshop scheduling across multiple concurrent engagements, balancing priorities, dependencies, and resource availability.
• Partner with application teams, infrastructure owners, and product stakeholders to gather pre workshop information, technical documentation, architecture diagrams, and required artifacts.
• Ensure threat modeling workshop scope, assumptions, and prerequisites are clearly defined and validated prior to execution.

2.Stakeholder Engagement & Partnership

• Serve as the primary coordination point between cybersecurity, engineering, architecture, and product stakeholders for threat modeling and secure design activities.
• Build strong relationships with development and infrastructure teams to promote early engagement with security and "shift-left" practices.
• Clearly communicate expectations, timelines, and outcomes to both technical and non-technical audiences.
• Escalate risks, delays, or blockers to appropriate leaders in a timely, structured manner.

Documentation, Tracking & Reporting

• Ensure threat modeling sessions and outcomes are accurately documented, including identified threats, assumptions, mitigations, and residual risks.
• Maintain high-quality records in designated tools and repositories, ensuring traceability from threats to corresponding controls or backlog items.
• Support audit-ready documentation and evidence requirements related to application and infrastructure security design.
• Produce regular reporting on volume, throughput, cycle times, and themes emerging from threat modeling activities.

Risk & Vulnerability Alignment

• Coordinate with vulnerability management and risk teams to align threat modeling outcomes with broader risk registers, remediation workflows, and standards.
• Ensure that critical threats and design weaknesses are properly logged, tracked, and dispositioned through established risk processes.
• Support remediation follow-up by partnering with technology owners to monitor progress on agreed mitigations.

Agile Ways of Working & Coordination

• Apply program and project management best practices to manage complex, multi workstream assessment activities.
• Maintain assessment roadmaps, intake queues, and execution plans aligned to business and technology priorities.
• Leverage Agile and Scrum style practices where appropriate, including backlog management, sprint planning, stand ups, retrospectives, and dependency tracking.
• Act as a servant-leader / facilitator for security-focused work, removing impediments and enabling smooth execution across teams.
• Contribute to the refinement of threat modeling playbooks, templates, and checklists to drive consistency and ease of use.

Education & Experience:

Bachelor's degree in Information Security, Information Technology, Risk Management, or a related field (or equivalent experience).

Experience (typically 5+ years) in application security, cybersecurity, IT risk management, software engineering, or technology program coordination.

Demonstrated experience coordinating or facilitating security activities such as threat modeling, security architecture reviews, or application/infrastructure security assessments in large, regulated, or complex environments.

Strong understanding of cybersecurity risk concepts (e.g., vulnerability, risk, threat, attack surface, mitigation)

Understanding of software development lifecycles (Agile, DevOps, CI/CD)

Preferred Qualifications:

Familiarity with structured threat modeling approaches and tools (e.g., STRIDE-style analysis, attack trees, or similar methodologies).

Familiarity with security and risk frameworks such as NIST CSF, NIST 800-53, ISO 27001, or CIS Controls.

Program or project management certifications (PMP, PgMP, PRINCE2) or Agile/Scrum certifications (CSM, SAFe, PMI ACP).

Familiarity with vulnerability management, remediation tracking, and risk acceptance processes.

Experience supporting metrics, dashboards, and SLA driven operational reporting.
