Staff Application Security Engineer

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 exceptional Staff Application Security Engineer to help us build a "Secure Paved Road"—an automated, self-service ecosystem that enables our 80+ R&D squads to build securely by default. What you’ll do Build the Secure Paved Road (Pipeline and Code) Pipeline Automation: Deeply integrate GitHub Advanced Security into the CI/CD pipeline to act as automated checkpoints, providing fast feedback to engineers without manual intervention. Secure by Default Code: Collaborate with Engineering to develop and maintain secure microservice templates and libraries with embedded security controls. Secrets and Supply Chain: Lead hardcoded secrets mitigation efforts by automating detection and building workflows to validate compromised credentials via API. Secure SDLC Practices: Drive cross functional initiatives to establish and continuously improve secure software development lifecycle practices across the organization. Continuous Security Testing and Validation Penetration Testing: Lead onboarding and operation of continuous penetration testing capabilities across web applications and services. Security Assessments: Participate in and help scale internal security assessments, penetration testing, and bug bounty programs. Tooling Ownership: Evaluate, prototype, implement, and operate security tools including DAST, SAST, and SCA. Simulation and Validation: Run proactive simulations based on emerging threats to validate defenses and identify gaps. Architecture and Threat Modeling Security Design Reviews: Lead security design reviews and threat modeling for new and existing services. Secure Architecture: Develop and maintain secure architecture standards, frameworks, and reusable patterns across multiple layers of the stack. Emerging Threat Analysis: Continuously analyze evolving security threats, determine relevance, and implement centralized mitigations. Operational Support and Engineering Partnership Technical Leadership: Act as the AppSec technical expert for the Security Champions Program, guiding engineers on vulnerability remediation and secure coding practices. Contextual Training: Implement just in time training mechanisms that help engineers remediate vulnerabilities as they are introduced. Triage to Automate: Own initial triage of vulnerability findings, identify patterns, and drive automation and guardrails to reduce recurring issues. Incident Response: Participate in security incident response and support post incident analysis and remediation efforts. Continuous Improvement and Expertise: Maintain strong knowledge of current security threats, vulnerabilities, and operational best practices, applying that knowledge to continuously improve the organization’s security posture. What you’ll bring Experience: 7-10+ years of experience in Product/Application Security, with a strong background in software engineering. Coding Expertise: Proficiency in C#/.NET (preferred) or Go/Java. Ability to read code to find vulnerabilities and write code to fix them. Modern AppSec: Experience moving security "left" using tools like GitHub Advanced Security, dependency scanners, and secret detectors. Automation Mindset: Proven ability to script (Python, Go, PowerShell) and automate security tasks. AI Forward: Interest in the intersection of AI and Security, specifically in securing AI workloads, leveraging AI capabilities to embed security throughout the SDLC, and using AI agents for defense. Why this role? Own Outcomes, Not Activity: Your success will be measured by real risk reduction. You will directly influence vulnerability backlog reduction, remediation velocity, and the overall security posture of the organization. Operate at the Intersection of Engineering and Security: You will work side by side with engineering teams to shape how software is built, secured, and deployed. This role gives you the platform to influence architecture, development practices, and platform level controls. Lead the Next Evolution of AppSec by defining how modern security teams leverage automation and intelligent systems to scale.
