Staff Security Engineer – AI/Agent security

Job Description

Company: Colossus Technologies Group

Location: Baltimore, US

Staff Security Engineer – AI / Agent Security

Remote (US) | Mid-$200Ks + Early-Stage Equity

We’re partnering with a fast-growing, early-stage cybersecurity company building the security layer for enterprise AI agents, MCP servers, skills, and plugins.

We’re looking for a senior security engineer who has lived on both sides of the problem: someone who started as a strong software engineer, became a hands-on security practitioner, and has gone on to build security products, platforms, or tooling.

This is not a traditional AppSec or security operations position. We’re looking for a builder who understands vulnerabilities and attacks firsthand and can turn that knowledge into production security capabilities.

What you’ll work on

• Build security products for AI agents, MCP servers, skills, and emerging agentic infrastructure
• Develop scanning and detection capabilities, including parsers, rule engines, analysis pipelines, and automated security checks
• Identify and detect risky or unauthorized AI/agent activity across enterprise environments
• Work across application security, endpoint detection, API security, software supply chain, and AI/LLM threats
• Design security capabilities from initial threat research through production implementation
• Help define how enterprises secure a rapidly evolving AI attack surface
What we’re looking for:
• 8+ years of software/security engineering experience
• Strong software engineering background with hands-on Python
• Experience as a security practitioner in areas such as Product Security, Application Security, offensive security, detection engineering, or security research
• Demonstrated experience building security tooling or products—not simply implementing or operating third-party tools
• Experience building scanners, detection systems, parsers, rule engines, security automat
