About The Role

We are seeking a highly skilled Senior Application Security Developer with a focus on Python development and AI/LLM security to join our dynamic team. This role is pivotal in enhancing our security posture by building, automating, and integrating advanced security capabilities into enterprise applications and CI/CD pipelines. The ideal candidate will possess a deep understanding of application security practices and have hands-on experience applying AI and large language models (LLMs) to security challenges.

Your expertise will help us develop innovative solutions for vulnerability detection, prioritization, analysis, and automated remediation, leveraging AI technologies to stay ahead of emerging threats. This position offers an exciting opportunity to work at the intersection of software development, security, and artificial intelligence, contributing to the development of secure, scalable, and intelligent security systems.

Qualifications The ideal candidate will have a strong background in Python development,



with proven experience in application security and AI/LLM security solutions. A solid understanding of secure software development practices and experience integrating security tools within CI/CD and DevSecOps pipelines are essential. Candidates should have hands-on knowledge of AI-assisted security techniques such as SAST, SCA, secrets scanning, vulnerability prioritization, and automated remediation.

Familiarity with LLMs, AI agents, RAG architectures, and AI model security—including prompt security, runtime protection, and model lifecycle management—is highly desirable. Additionally, a good understanding of cloud-native architectures and cloud security principles is required.

Experience with API integration for AI models (like OpenAI or Anthropic) and the ability to translate security requirements into automated AI workflows will be considered advantageous.

Responsibilities In this role, you will develop Python-based security applications, APIs, and automation tools to streamline security processes. You will build and enhance application security capabilities across the software development lifecycle, ensuring security is embedded from inception to deployment.

Your responsibilities include integrating SAST, SCA, secrets scanning, and vulnerability management tools into development workflows, as well as developing AI-assisted capabilities for vulnerability analysis, exploitability assessment, and automated remediation. You will design and implement security controls and guardrails for LLM and AI-enabled applications,



supporting AI Security Posture Management (AI-SPM) and asset inventory initiatives. Automating security processes and embedding security features into CI/CD pipelines will be central to your role.

Additionally, you will contribute to establishing AI security standards, ML SecOps practices, and secure AI development guidelines, ensuring best practices are followed across the organization.
