🚀 The Opportunity

Flywire is seeking an eager and skillful Application Security Engineer to join our elite Security Team. You will support our security efforts across our global development houses, ensuring the privacy and safety of our most confidential business and personal information.

At Flywire, we don’t just "check for bugs"—we build security into the heart of our products. If you have a "breaker" mentality and a passion for secure architecture, this journey is for you!

🎯 Your Impact & Key Responsibilities

Your mission is to ensure security is never an afterthought. You will be an active player in every aspect of the development lifecycle:

1. Security by Design & Architecture

• Define the Standard: Draft comprehensive security requirements for every new system, service, or integration needed by Flywire.

• Lead the Blueprint: Own the threat modeling and secure architecture initiatives to prevent vulnerabilities at the design stage.

• Technical Leadership: Perform lead tasks, providing guidance to other team members and setting technical standards.

2. Engineering Partnership & Collaboration

• Embed with Teams: Attend engineering syncs and collaborate frequently with different squads to identify and address security issues in real-time.

• Full-Stack Reviews: Perform deep-dive security reviews, from meticulous source code auditing to dynamic testing of live applications.

• Review & Integrate: Execute technical tasks on change and integration reviews to ensure "security-first" deployments.

3. S-SDLC Mastery

• End-to-End Ownership: Be an active part of the secure software development lifecycle (S-SDLC).

• Hands-on Remediation: Don’t just find flaws—provide expert guidance to developers on how to mitigate and fix them effectively.

🧠 Here’s What We’re Looking For

The Experience

• 4+ years in Application Security (AppSec).

• Proven experience performing web application penetration tests and vulnerability research.

• Strong skills in source code auditing and development of custom security tools.

The Tech Stack & Knowledge

• Languages: Proficiency in Ruby on Rails, Java, and modern web dev (JavaScript, Python, Node.js).

• The "Breaker" Mindset: Ability to think like an attacker to identify flaws while effectively crafting mitigating controls.

• Modern Standards: Deep understanding of OWASP Top 10 and the OWASP Top 10 for LLM Applications (AI-driven security).

• Authentication: Working experience with OAuth, SAML, and SSO.

• DevSecOps: Experience with SAST/DAST/SCA tools and integrating them into CI/CD pipelines.

• Compliance: Knowledge of security audit certifications such as PCI-DSS, SOC 1, and SOC 2.

Soft Skills

• Master Communicator: Ability to explain complex technical findings to both technical and non-technical audiences with empathy and clarity.
