As part of your daily tasks, you will:

• Conduct penetration tests (network, social, physical, adjacent, and more) that target Organizations, Networks, Application and Cloud infrastructure and evaluate their security defenses in depth.
• Assess the security posture of applications (mobile, web / cloud, core networks, etc.) via functional testing, fuzz testing and other applicable methodologies.
• Review the security maturity of edge systems (IoT, kiosk terminals, operator terminals, etc.) that are interconnected via public or private networks.
• Conduct targeted research for the purposes of understanding a vendor‑specific technology, identify its security critical components, and prioritize impactful attack vectors.
• Document and present security risks & mitigation recommendations in both technical‑ and business‑oriented language.

Minimum Qualifications

• BSc or MSc in Electrical Engineering, Computer Science, Computer Engineering, or equivalent practical experience.
• 4+ years of experience in VAPT, IT security or application security (mobile, web front‑end, backend, etc.) related roles. Experience can be an assessment / consultancy role, an equivalent role in other engineering organizations, or a combination of them.
• Proven experience in vulnerability assessment, penetration testing or security testing at the network, application, or system level.
• Active Directory and Cloud Infrastructure Knowledge.

• Experience with Information Security fundamentals (risk management, security best practices, data protection, communication encryption, authentication, authorization, etc.) and cyber threats of modern systems & networks.
• Experience with the technologies and security controls present in application (web full‑stack, WAF, EDR, data encryption, transport protection, etc.), network (firewalls, segmentation, IDS/IPS, VPN, etc.) and Windows / Linux system (privileges, roles/groups, AV/Endpoints, secret storage, etc.) architectures.
• Experience in identifying, exploiting, and reporting vulnerabilities in the context of Red Team / VAPT tasks (OWASP Web / Mobile Top10 vulnerabilities, access control, insecure configurations, secrets management, etc.).
• Experience in Active Directory Attacks (Pass‑the‑Hash, Pass‑the‑Ticket, Kerberoasting, Golden Ticket, Silver Ticket, DCSync, Credential dumping, Abuse of ACLs, Lateral movement via SMB, etc.).
• Experience in using pentest and other security‑related tools for information gathering, vulnerability discovery, exploitation, evasion, persistence, and pivoting in Cloud environments.
• Experience with authentication, authorization, role‑based ACL, identity, and access management methods, such as OAuth, MFA, SSO, JWT, PKI, Cloud IAM, etc.
• Experience with basic cryptographic primitives, such as symmetric & asymmetric encryption, authenticated encryption, key derivation, and key exchange.
• Ability to monitor the current threat landscape, emerging threads and follow their technical analysis and published exploitation techniques.
