BrainRocket is a global company creating end-to-end tech products for clients across Fintech, iGaming, and Marketing. Young, ambitious, and unstoppable, we've already taken Cyprus, Malta, Portugal, Poland, and Serbia by storm. Our BRO team consists of 1,300 bright minds creating innovative ideas and products. We don’t follow formats. We shape them. We build what works, launch it fast, and make sure it hits. We invite a Penetration Testing Team Lead to join our team. It's an office-based role. Core Mission To lead and grow the Offensive Security function while maintaining a strong hands-on role. Leverage an attacker mindset to identify critical business logic vulnerabilities and attack paths (kill chains), drive collaboration with Application Security and Security Operations teams, and lead purple team activities.
✔️ Build the Offensive security function from the ground up: define methodologies, reporting standards, and the hiring plan for future team expansion. ✔️ Recruit, mentor, and develop the team of offensive security engineers, ensuring technical excellence and consistent delivery quality once hired. ✔️ Perform deep-dive manual penetration testing for complex, high-risk, or business-critical assets, focusing on realistic attack scenarios rather than high-volume "bug-bounty style" findings. ✔️ Lead and coordinate purple team exercises with the SOC/Blue Team, simulating real-world attacks to validate detection capabilities and tune SIEM/EDR rules. ✔️ Collaborate closely with the Application Security Team to validate vulnerabilities and guide effective remediation strategies. ✔️ Translate offensive findings into actionable threat intelligence, TTPs, and recommendations to enhance detection and threat hunting. ✔️ Act as a subject matter expert in security architecture discussions, secure design reviews, and security code reviews. ✔️ Stay current with emerging attack techniques, tools, and security trends, and ensure knowledge is shared within the engineering teams.
✔️ Strong "playing coach" mindset: willingness to remain highly hands-on (70-80%) while setting up the function. ✔️ Deep understanding of penetration testing methodologies and frameworks (OWASP Top 10, SANS Top 25). ✔️ Demonstrated experience contributing to purple team exercises and working closely with SOC to improve detection logic. ✔️ Strong hands-on experience with industry-standard tools (Burp Suite Pro, Metasploit, Nmap, etc.) and ability to develop custom automation (Python, Go, PowerShell, Bash). ✔️ Solid knowledge of network protocols (TCP/IP, HTTP/S, DNS), operating systems (Linux, Windows), and cloud-native architectures (Docker, Kubernetes). ✔️ Excellent communication skills, with the ability to clearly present critical business risks to both technical and non-technical stakeholders.
