Staff Software Engineer – Security Products / AI Security

Remote (US) | Mid-$200

Ks + Early-Stage Equity

We’re partnering with a fast-growing, early-stage technology company building security products that protect enterprises as they adopt AI agents, MCP servers, skills, plugins, and other emerging AI infrastructure.

We’re looking for a Staff-level Software Engineer who builds security into products.

This person should come from a strong software engineering background and have experience building customer-facing security products, platforms, scanners, detection systems, or developer security tooling that users actually consume.

This is not a traditional cybersecurity operations, SOC, or internal security engineering role. You won’t be implementing someone else’s security platform or primarily protecting an internal corporate environment.

You’ll be building the security product itself.

• Build customer-facing security capabilities for AI agents, MCP servers, skills, plugins, and agentic infrastructure
• Design and develop scanning engines, detection systems, parsers, rule engines, and analysis pipelines
• Build technology that identifies vulnerabilities, risky behaviors, misconfigurations, and unauthorized AI activity
• Develop automated security checks that can operate at scale across customer environments
• Turn security research and emerging attack techniques into production software features
• Build APIs, services, and backend systems that power security products
• Work across application security, API security, software supply chain, endpoint/asset discovery, and emerging AI/LLM threats
• Own features from architecture and development through testing, deployment, and production
• Help define how security products need to evolve as AI agents become more deeply integrated into enterprise environments

• 8+ years of professional software engineering / security product engineering experience
• Strong software engineering fundamentals and experience building production systems
• Experience building commercial or customer-facing security technology
• Background building security products such as:
• Vulnerability scanners
• Security analysis platforms
• SAST / DAST / SCA products
• EDR / XDR technology
• API security products
• Security automation platforms
• Asset discovery or attack-surface technology
• Experience designing parsers, rules engines, detection logic, analysis pipelines, or scanning infrastructure
• Strong understanding of application and API security
• Ability to take an ambiguous technical/security problem and turn it into a scalable production product
