Client Security Expert or Architect

You will identify and remediate client-side security risks, lead mobile offensive and defensive exercises, analyze attacker techniques, and build systematic defenses. You may also design client-security architecture, optimize security-data pipelines, and incorporate AI Agent capabilities into automated security strategies and countermeasures.

Responsibilities

• Identify client-side security risks, propose solutions, and drive implementation.
• Lead offensive and defensive exercises on mobile clients and remediate business-related risks.
• Analyze black- and gray-market attack techniques, reconstruct attack mechanisms, and produce countermeasure plans.
• Design and build systematic client-side defense solutions.
• Own the overall architecture design for client-side security.
• Design and optimize backend security-data collection, processing, and analysis pipelines.
• Incorporate AI Agent capabilities into intelligent security strategy operations and automated countermeasure architecture.

Requirements

• Bachelor's degree or above in Computer Science or a related field.
• Be familiar with low-level Android and iOS system architecture, security mechanisms, and reverse engineering.
• Be familiar with cheating and fraud techniques used by black- and gray-market actors.
• Be proficient in using AI Agents for security workflows, including reverse engineering, vulnerability discovery, attack reconstruction, and log and data analysis.
• Have 3+ years of experience in backend development or architecture design for the Architect role.
• Have strong backend architecture skills and expertise in high-concurrency, high-availability distributed system design.
• Be familiar with client security domains such as device fingerprinting, environment detection, and behavioral risk control.
• Be familiar with AI Agent technical principles and application paradigms.
