About the role

Responsibilities

  • Build AI augmented code review to get involved in important systems at the right time.
  • Build a least-privilege and JIT system for cloud access that enables engineers and enforces least privileges.
  • Implement a safe environment for agents to engage with code.
  • Implement a framework for securely handling agent manipulation of user systems (e.g., MCP tool calls and command execution).
  • Implement a paved road for preventing inappropriate data from being logged.

Requirements

  • Strong software engineer first, with security as your superpower.
  • Think like both a builder and an attacker: anticipate vulnerabilities before they become issues.
  • Care about developer experience, building solutions that are secure and frictionless.
  • Comfortable moving quickly, owning problems end to end, and iterating with limited guidance.
  • Experience building or scaling secure systems in fast-moving environments.
  • Strong opinions on secure defaults, but can balance pragmatism with rigor.
  • Enjoy working on small, high-talent teams where impact is magnified.
  • Motivated by protecting developers and users, and see security as an enabler.
