Agentic scanning systems: Build systems that autonomously explore applications, maintain context, and execute complex testing strategies.

• Security detection engine: Design and implement reliable, production-grade vulnerability detection logic (injection, auth issues, business logic flaws, etc.).
• AI-driven testing: Integrate LLMs and structured reasoning into scanning workflows to improve coverage and reduce false positives.
• Distributed infrastructure: Work on systems that orchestrate thousands of concurrent scans (Kubernetes, queues, resource management).
• Performance & reliability: Ensure scans are fast, deterministic, and cost-efficient despite high complexity and concurrency.
• Core platform design: Contribute to architecture decisions around memory systems, execution environments, and data models. Our Tech Stack & Focus
