This client is revolutionizing the $2 B threat modeling market with the first AI-native secure-by-design platform. Our AI agents automate security design reviews, threat modeling, and enforcement of security requirements—empowering development teams to build secure software without friction.

The Role

We’re looking for a Founding AI Engineer to design and develop autonomous agents capable of reasoning about software security, integrating with modern development workflows, and automating complex security processes.

What You’ll Do

• Develop AI Agents: Build and deploy intelligent systems that analyze security policies, threat models, and design documentation.
• Automate Security with AI: Implement models that extract business logic and generate structured security requirements pre-code.
• Reasoning & Decision Systems: Design multi-agent architectures to conduct security reviews and enforce compliance at scale.
• Workflow Integrations: Integrate with tools like Git Hub, Jira, Notion, AWS, and Terraform to surface security insights in real time.
• LLM & Model Engineering: Fine-tune and evaluate LLMs to improve the accuracy and contextual relevance of security recommendations.
• Compliance Intelligence: Build systems that validate security controls against frameworks like SOC 2, ISO 27001, and CISA’s Secure-by-Design.
• Scalability & Performance: Optimize for speed and efficiency when analyzing large-scale codebases and documentation.

What You Bring

• AI & ML Expertise: 3+ years of experience with LLMs, reinforcement learning, or autonomous agents.
• Security Know-How: Solid understanding of secure software design and threat modeling methodologies.
• Reasoning Systems: Familiarity with constraint-solving, symbolic reasoning, or decision-making AI.
• Tech Stack Proficiency: Python, plus AI/ML frameworks like Py Torch, Tensor Flow, Lang Chain, Open AI APIs.
• Dev Sec Ops Experience: Comfortable with version control, CI/CD, and secure development lifecycles.
• APIs & Integrations: Experience with APIs and connecting to developer ecosystems (Jira, Git Hub, AWS).
• Security Tooling: Knowledge of tools like SAST, DAST, CSPM, and compliance workflows.

Bonus Points

• Experience with Semgrep, Code QL, or Snyk
• Knowledge of graph reasoning, semantic analysis, or symbolic AI
• Familiarity with cloud security (AWS, GCP, Azure) and Terraform/Kubernetes
• Industry experience in fintech, healthtech , or other regulated environments
