At Flywire, security isn’t a checkbox—it’s a foundational pillar of how we build. We are looking for a high-impact Senior Security Engineer I, Application Security to act as a technical visionary, bridging the gap between robust defense and rapid innovation. We expect this role to be able to blend traditional security architecture with new technologies like AI-driven automation.
Key Responsibilities
- AI-Driven Security Automation: Design, prompt-engineer, and deploy automated security review workflows, using for example Claude or other LLM APIs to perform real-time code analysis and architectural reviews within our CI/CD setting.
- Security Design & Architecture: Lead secure design reviews and advanced threat modeling for our complex payment systems and AI integrated applications.
- Engineering Collaboration & Leadership:
Act as a technical bridge between Security and Engineering teams. Collaborate frequently with different engineering teams to identify and address security issues.
- Advanced Full-Stack Reviews: Oversee deep-dive technical reviews, moving beyond basic scans to perform source code audits and live application testing on high-risk features.
- Automation & SDLC: Contribute and take ownership for the automated security controls we are building and take an active part in every aspect of the secure software development lifecycle (S-SDLC).
- Mentorship & Guidance: Provide hands-on remediation guidance and mentor junior security or software engineers, also members of Product teams, on both traditional exploits and emerging AI-specific vulnerabilities.
