  • Establish and run an evidence-based mobile application security assessment and review program, including methodology, prioritization, acceptance criteria, escalation, automation, and measurement.
  • Identify recurring weaknesses and drive reusable platform-level security solutions rather than repeated application-specific fixes.

  • Ability to identify systemic issues across multiple applications and translate them into reusable platform controls, standards, or engineering frameworks.
  • Experience with product security architecture and threat modeling at significant scale.
  • Demonstrated ability to influence senior engineers and engineering leaders and drive changes in engineering practice.
