Senior Application Security Engineer, AI

Introduction

Ready to be a Titan? At ServiceTitan, we are transforming product security into a core part of how engineering delivers software. We are looking for an AI-Focused Senior Application Security Engineer to help define and deliver a secure paved road, creating automated, developer friendly security patterns that enable our 80 plus R&D teams to build securely by default without slowing down innovation.

Responsibilities

• Secure-by-Design Engineering Pipeline Automation: Embed security directly into the development pipeline through intelligent prompting and AI driven agents.
• Secure-by-Default Code: Collaborate with Engineering to develop and maintain secure microservice templates and libraries that have security controls built in from the start.
• Supply Chain Protections: Implement controls to secure dependencies, build artifacts, and third party integrations. Partner with engineering to enforce integrity, provenance, and policy checks within build and release workflows.

AI-Driven Security

• AI-Driven Security Testing & Validation: Evaluate, configure, and implement AI agentic tooling to autonomously test our web applications for vulnerabilities.
• Simulation & Validation: Use agentic tooling to run proactive simulations based on emerging threats to validate our defenses in real time.
• Outcome Accountability: Drive adherence to vulnerability remediation SLAs by partnering with engineering teams to track, prioritize, and resolve security issues.

AI & Identity Security

• AI Guardrails: Design and implement technical guardrails for AI Coding Agents and Model Context Protocols (MCP) to ensure safe adoption of AI in the development lifecycle.
• AI-Driven Tooling: Help operationalize AI based tooling to act as a "GPS" for developers, tuning the system to provide accurate, on demand threat modeling, design, and development advice.
• Non-Human Identity Management: Partner with engineering to define and implement strategies for managing machine identities across AI systems.
