Original job description

About Finix

Finix is building the global operating system for fintech, starting with payments. From startups to publicly traded companies, Finix processes tens of billions of dollars annually both in-store and online. Finix was founded in 2015 and is headquartered in San Francisco.

To date Finix has raised over $200M, including a $75M Series C led by Acrew Capital and Lightspeed Venture Partners and backed by American Express Ventures, Bain Capital Ventures, Homebrew, Inspired Capital, Visa, and others

About the Role:

The Engineering organization at Finix owns the delivery and stability of our product end to end. As an Offensive Security Engineer, you will find weaknesses in Finix’s applications, cloud infrastructure, and corporate environment before attackers do, and work with engineers to fix them. You will run our internal penetration testing program and work closely with Engineering, Information Security, Compliance, and IT.

This is an in-office position based in our San Francisco office.

You Will:

Plan and run red team tests across our web applications, APIs, AWS infrastructure, Kubernetes, and corporate environment
Perform PCI DSS penetration testing and segmentation testing for our cardholder data environment as a Level 1 service provider
Test new features and architecture changes, and partner with Engineering on threat modeling and secure design
Review source code, especially Java services, for security flaws, and help engineers understand and fix them
Run purple team exercises with detection and incident response to validate and improve our alerting
Validate and reproduce bug bounty and third-party pentest findings, and assess their real-world impact
Write clear reports with reproducible steps, business impact, and practical remediation guidance, and retest fixes
Build tooling and automation to scale offensive testing and catch regressions
Use frontier AI models to accelerate offensive testing, including building AI-assisted workflows and agents for recon, code review, vulnerability discovery, and exploit validation
Deploy and operate self-hosted AI models for security testing, so source code, findings, and sensitive data stay inside Finix’s environment
Test internal AI tooling and LLM integrations for prompt injection, data leakage, and abuse

You Have:

4+ years of hands-on offensive security experience, such as penetration testing, red teaming, or application security testing
Deep web application and API testing skills
Experience attacking cloud environments, especially AWS
Proficiency in Python or Go, the ability to read and review Java code, and mastery with tools like Burp Suite
Hands-on experience using frontier AI models in offensive security work, such as AI-assisted code review, fuzzing, or automated testing agents
Strong ability to explain findings and risk to engineers and non-technical stakeholders
Sound judgment and respect for scope and rules of engagement when testing production-adjacent systems

Nice to Have:

Published CVEs, security research, conference talks, or recognition in bug bounty programs
CTF experience
Kubernetes and container security testing (EKS)
Mobile or Android application testing
Active Directory, Okta, or identity provider attack techniques
Familiarity with payment systems, such as card networks, HSMs, or ISO 8583
LLM and AI application security testing
