Perform security assessments of banking hardware and connected/IoT technologies (limited but expected), including ATMs, POS devices, and other embedded endpoints.
Collect and validate pre-requisites for each engagement, ensuring access, documentation, and approvals are in place (including lab/onsite testing logistics and device access where applicable).
Perform manual and automated testing to identify vulnerabilities, misconfigurations, and security weaknesses, leveraging industry-standard tools and custom scripts.
Document and communicate findings through comprehensive reports with technical details, risk assessments, and actionable remediation recommendations.
Conduct peer reviews of penetration test reports to ensure accuracy, consistency, and quality of deliverables.
Collaborate with development, infrastructure, security, and device/product engineering teams to clarify findings, support remediation efforts, and provide subject matter expertise on offensive security.
Stay current with emerging threats, vulnerabilities, and attack techniques by leveraging threat intelligence, security research, and participation in relevant industry groups.
Contribute to the continuous improvement of penetration testing methodologies, tools, and frameworks to align with firm strategy and regulatory requirements.

Requirements

5+ years of hands-on penetration testing experience in offensive security, with a proven track record of scoping, executing, and reporting on complex engagements.
Expertise in manual penetration testing of web, API, cloud (AWS/Azure/GCP), infrastructure, thick-client, and/or mobile (Android/iOS) applications, including use of industry-standard tools (e.g., Burp Suite, Nmap, Metasploit, etc.).
Working knowledge of testing approaches for connected devices/IoT and purpose-built banking devices (e.g., ATMs, POS), including common attack surfaces such as exposed services, remote administration paths, authentication/authorization, hardening gaps, and insecure configurations.
Strong understanding of security assessment methodologies such as OWASP Top Ten, NIST Cybersecurity Framework, and other relevant standards.
Ability to identify and articulate systemic security issues related to threats, vulnerabilities, and risks, and provide clear, actionable remediation recommendations.
Exceptional organizational and communication skills, including the ability to write detailed technical reports and present findings to both technical and non-technical stakeholders.
