Job Overview

Movable Ink is hiring a Product Security Engineer to help secure our codebases, CI/CD pipelines, and development practices. To succeed in this role, you'll balance a security-first mindset with a practical understanding of how engineering teams ship software—finding ways to reduce risk without slowing down delivery. This is a hands-on opportunity to build and improve the automation that keeps our code and infrastructure safe, working closely with both the Security and Engineering teams. As AI coding tools and supply chain attacks increase risk across the industry, this role is critical to staying ahead of vulnerabilities before they reach production.

Responsibilities

• Implement and maintain static application security testing (SAST) using Semgrep across our repositories
• Configure and improve software composition analysis (SCA) tooling (Dependabot) to identify vulnerable dependencies
• Manage secrets detection scanning (Trufflehog) and respond to findings
• Integrate security scanning into CI/CD pipelines (GitHub Actions) to catch issues before code is merged
• Triage and prioritize vulnerability findings, working with engineering teams to drive remediation
• Support dynamic application security testing (DAST) efforts using tools like ZAP
• Contribute to our Application Security Posture Management (ASPM) platform to centralize findings and track remediation
• Set up and configure automation scripts to support our vulnerability management practices
• Document secure coding guidelines and help educate developers on security best practices
• Evaluate and recommend new security tools as the landscape evolves

Qualifications

• 2+ years of experience in application security, DevSecOps, or a security-focused software engineering role
• Hands-on experience with SAST, SCA, or secrets scanning tools (Semgrep, Dependabot, Snyk, or similar)
• Familiarity with CI/CD pipelines and GitHub Actions
• Understanding of common web application vulnerabilities (OWASP Top 10) and how to detect/prevent them
