Penetration Tester

We’re looking for a Penetration Tester who wants to do real security research across web, infrastructure, cloud, AI and mobile environments.

Our work spans web applications, infrastructure and networks, cloud and Kubernetes environments, AI systems, mobile applications, and source code. For us, penetration testing is not just about running tools, it’s about understanding how systems work, challenging assumptions, and conducting real security research.

You’ll report to the Team Lead and work alongside a small team of security researchers in an international, collaborative, and highly technical environment. You’ll work independently on complex problems and together with the team on live client engagements.

We’re looking for someone curious and hungry to learn, someone who goes deep without being told to, would rather understand the system than simply run the tool, and genuinely enjoys security research.

Responsibilites:

• Conduct penetration testing and security research across web applications, infrastructure and networks, cloud and Kubernetes environments, AI systems, mobile applications, and source code

• Take ownership of security reporting. We use AI tools to accelerate drafting, but you are accountable for the final output — including technical accuracy, root-cause analysis, and real-world business impact

• Present vulnerabilities, findings, and recommendations clearly to clients and their technical teams

• Build internal security tools, methodologies, automation, and agentic workflows that enable the team to work faster and go deeper

• Contribute to red team and adversary emulation engagements

• Independently investigate unfamiliar technologies, attack surfaces, and complex technical problems

Must Have Requirements:

• 3+ years of hands-on experience in penetration testing and/or security research-mandatory

• Deep expertise in at least two of the following areas:

• Web application penetration testing

• Infrastructure and network penetration testing, including Active Directory, with real fluency in Windows and Linux internals, the protocols underneath, and privilege escalation

• Manual source code review and vulnerability research

• OSCP or CREST CRT certification- mandatory

• Currently based in Singapore with valid work authorization- mandatory

• Strong research mindset, technical curiosity, and the ability to independently investigate unfamiliar technologies and attack surfaces

• Hands-on experience using AI tools to support security testing, research, automation, or tool development, with a strong interest in exploring new AI-driven security workflows
