About the role

  • Build and improve Watch products: static and dynamic scanning for MCP servers, skills, plugins, and agent behavior detection on endpoints.
  • Develop shadow detection: identify unregistered MCP servers, skills, plugins, and agents running outside governance across the enterprise.
  • Own AppSec for the platform: penetration testing, vulnerability management, dependency scanning, and security hardening of the control plane.
  • Build automated version scanning: CI/CD-integrated security checks that run on each new MCP server version, skill update, or plugin release.
  • Extend detection coverage to CLI agents (Codex, OpenCode) and browser-based agents.

Requirements

  • 8+ years in security engineering with deep experience in application security, security tooling development, or endpoint detection.
  • Builder, not operator. You've created scanning or detection systems: parsers, rule engines, analysis pipelines.
  • Experience with shadow IT detection, asset discovery, or endpoint monitoring in enterprise environments.
  • Strong Python skills (our scanning pipeline and platform backend are Python/FastAPI).
  • Understanding of API and gateway attack patterns: SSRF, token theft, injection, supply-chain attacks.
  • Awareness of emerging AI/LLM security threats: prompt injection, tool poisoning, jailbreaking, indirect prompt injection through tool responses.
Benefits
  • Competitive salary and equity — compensation that reflects your expertise and customer-facing responsibilities.
  • Paid time off — 4 weeks paid vacation, paid sick leave, and paid parental leave.
  • Professional development — budget for conferences, courses, and certifications in AI, enterprise software, and customer success.
  • Top-tier equipment — your choice of laptop and accessories to create your ideal work environment.
  • Health benefits — comprehensive health, dental, and vision coverage.
  • Customer interaction opportunities — work directly with innovative companies and see the immediate impact of your work.
