Overview:

We re hiring a Senior Penetration Tester to help defend our fintech platform against large-scale payment fraud, carding attacks, and other financially motivated threats. You ll lead offensive security assessments targeting our transaction systems, authentication flows, and APIs with a heavy focus on automation and scalability. Your work will directly impact our fraud defenses, detection strategy, and customer trust.

This is a highly technical, hands-on role for someone who thrives in a fast-paced, high-stakes fintech environment.

Responsibilities:

Lead penetration testing engagements focused on payment abuse, transaction manipulation, and business logic exploitation.
Design and execute automated attack simulations to test our defenses against:

Carding and BIN attacks
Credential stuffing and account takeovers
Checkout and payment flow abuse
API-level enumeration and fraud

Build custom tooling and frameworks to mimic the behavior of real-world fraudsters and cybercriminals.
Partner with fraud engineering, product security, and risk teams to identify weak points in our controls, detection systems, and architecture.
Conduct threat modeling and red teaming exercises related to payments, authentication, and user account abuse.
Document findings in technical reports with clear risk impact, exploitability, and remediation guidance.
Mentor junior testers and contribute to a culture of security innovation and continuous improvement.

Qualifications:

7+ years of experience in offensive security, penetration testing, or red teaming.
Strong background in payment systems, financial fraud tactics, and transaction-level attack surfaces.
Fluency in scripting and automation (e.g., Python, JavaScript, Go, Bash) to simulate attacker workflows at scale.
Familiarity with tools like Burp Suite Pro, Selenium, Scapy, ffuf, SQLMap, Metasploit, and bot automation frameworks.
In-depth knowledge of fintech technologies (e.g., tokenized payments, card vaulting, 3DS, ACH, real-time payment APIs).
Solid grasp of common attacker techniques: carding, fake identity generation, bypassing rate limits, evading fraud filters, and abusing web/app logic.
Strong communication skills for explaining findings to both technical and non-technical audiences.

Nice to Haves

Certifications: OSCP, OSEP, GWAPT, GPEN, GCPN, GXPN, GX-PT, CPSA/CRSA by CREST, CHECK, or TIGER.
Prior experience in a fintech, digital banking, or payment gateway environment.
