Senior Agentic Security Automation Engineer

Role Description

We're looking for a Senior Agentic Security Automation Engineer who thrives on technical challenges, enjoys building things from scratch, and has an insatiable curiosity for how software works, how it breaks, and how it can be analyzed autonomously.

In this role, your goal won't be to perform security assessments by hand. You'll:

• Design agentic workflows
• Build automation frameworks
• Integrate security tooling
• Develop evaluation systems
• Create infrastructure for autonomous analysis of applications

Success in this role means helping transform security testing from a human-limited activity into a technology-enabled capability that can:

• Analyze more applications
• Execute more test coverage
• Identify more meaningful security issues
• Continuously improve over time

Your first mission is to make our offensive security team faster and more effective in a repeatable way.

Qualifications

• Coding experience in Python, JavaScript, or TypeScript
• A solid security background
• Curiosity and aptitude for AI
• U.S. citizenship

Requirements

• Hands-on experience building with LLMs (Claude, GPT, Gemini, or similar)
• Experience with agentic frameworks or Retrieval-Augmented Generation (RAG)
• Demonstrable experience building agentic workflows with LangGraph, Semantic Kernel, AutoGen, or similar
• Experience integrating telemetry from multiple security tools into a unified analysis engine
• Production experience with tool/function calling, structured outputs, prompt engineering, context management, and evaluation frameworks
• Experience with Java, Go, or additional languages
• Production engineering and MLOps experience
• Mobile or desktop application security testing experience
• Reverse engineering experience
• Experience building MCP servers
• Experience training or fine-tuning machine learning models
• A track record of building custom security tools
• Contributions to open-source security or AI projects
• Experience supporting both commercial and U.S. government customers
• Published security research, presentations, or conference talks

Benefits

• Base salary range: $120,000 - $160,000 per year
• Eligibility for bonuses and equity grants
• Comprehensive benefits package including health insurance
• 401k with company match
• Paid parental leave
• Home Office Stipend
• Flexible PTO
• Remote-first work environment
