As a Senior Penetration Tester, you will play a central role in identifying, assessing, and mitigating security vulnerabilities across our digital ecosystem. You will lead complex technical evaluations spanning modern web applications, backend architectures, APIs, and cloud-native environments, helping engineering teams build resilient, secure-by-design solutions.

• Drive Offensive Security: Plan, scope, and execute comprehensive penetration tests on modern web applications, backend microservices, REST/GraphQL APIs, and cloud-native environments (AWS, Azure, or GCP).
• Threat Modeling & Architecture Review: Collaborate closely with development and DevOps teams early in the design phase to conduct threat modeling and review architectures, ensuring security is baked in from day one.
• Vulnerability Analysis & Exploitation: Perform deep-dive manual and automated vulnerability analyses, uncovering complex flaws like business logic bypasses, authorization failures, and server-side request forgeries.
• Technical Reporting & Remediation Guidance: Author high-quality, actionable technical reports that translate complex technical risks into clear business impacts, providing pragmatic remediation guidance to our engineering squads.
• Tooling & Innovation: Develop custom testing scripts and explore cutting-edge offensive workflows, including integrating AI-assisted security testing and LLM-augmented vulnerability analysis to maximize speed and coverage.

• Degree in Computer Science, Cybersecurity, IT, Software Engineering, or equivalent practical experience in offensive security.

• Hands-on experience (ideally 3+ years) conducting technical security assessments, with a strong focus on web applications, APIs, and cloud infrastructure.

• Offensive Security Expertise: In-depth knowledge of backend technologies, secure protocols, and security standards (e.g., OWASP Top 10, ASVS, WSTG, OAuth 2.0).
• Cloud & Modern Tech: Solid familiarity with assessing cloud environments (AWS, Azure, or GCP), IAM configurations, container security (Docker, Kubernetes), and microservices.
• Tools & Scripting: High proficiency with industry-standard offensive tools (e.g., Burp Suite Pro, OWASP ZAP, Postman) combined with scripting skills (e.g., Python, Bash) to automate testing workflows.

• An analytical and structured problem-solver who enjoys working collaboratively across cross-functional teams to build collective security resilience.

• A curious, continuous learner with a passion for offensive security, exploring new technologies, and a strong drive to mentor and share knowledge with others.
