Role Overview We are looking for an experienced Senior Penetration Tester with 5+ years of hands-on experience in offensive security and penetration testing. The individual will work as a hands-on Individual Contributor, independently planning and executing complex assessments across web applications, APIs, networks, cloud environments, Active Directory, and enterprise infrastructure. The role requires strong business understanding: the candidate must understand the customer's business model, critical processes, architecture, data flows, crown-jewel assets, and threat landscape and use that context to design risk-driven penetration tests. The individual will also support the SOC through threat hunting, advanced investigations, incident advisory, attack-path analysis, and technical security guidance.
Key Responsibilities
1. Penetration Testing & Security Assessments
· Independently plan, scope, execute, document, and close penetration testing engagements from scoping through retesting.
· Perform advanced Web Application, API, Network, Mobile, Cloud, Active Directory, and Infrastructure penetration testing.
· Conduct authenticated and unauthenticated assessments and validate vulnerabilities through controlled exploitation.
· Identify attack chains by combining vulnerabilities, misconfigurations, weak controls, and identity risks.
· Develop exploit Proof-of-Concepts (PoCs), validate impact, and provide practical remediation guidance.
· Perform manual testing beyond automated scanner results and validate remediation through retesting. 2. Business & Risk-Based Penetration Testing
· Understand customer business models, critical workflows, applications, data flows, technology architecture, and critical assets before testing.
· Translate business requirements and threat scenarios into an appropriate penetration testing strategy.
· Prioritize findings using business criticality, exploitability, exposure, attack path, data sensitivity, and potential operational or financial impact.
· Design realistic attack scenarios relevant to the customer's industry and threat landscape.
· Translate technical weaknesses into business risk and provide practical recommendations aligned with operational constraints. 3. Advanced Offensive Security
· Conduct adversary simulation and advanced penetration testing activities where applicable.
· Perform attack-path analysis covering initial access, privilege escalation, credential compromise, lateral movement, persistence, defense evasion, and controlled data-access/exfiltration simulation.
· Perform Active Directory security assessments and identify privilege-escalation and identity attack paths.
· Conduct cloud attack-path assessments across AWS/Azure environments.
· Research emerging vulnerabilities, exploits, TTPs, and offensive security techniques. 4. Web & API Security
· Perform comprehensive manual Web and API testing aligned with OWASP Top 10, OWASP API Security Top 10, and OWASP WSTG.
· Test authentication, authorization, session management, access controls, business logic,
input validation, API security, and sensitive-data exposure.
· Assess and exploit vulnerabilities such as IDOR/BOLA, privilege escalation, SSRF, injection, authentication bypass, business-logic flaws, and insecure deserialization.
· Perform business-logic testing based on real application functionality and customer workflows. 5. Cloud & Infrastructure Security
· Assess AWS/Azure IAM, networking, storage, workloads, secrets, security groups/NSGs, logging, and configuration controls.
· Identify attack paths across cloud identities, workloads, storage, and network components.
· Perform internal and external network/infrastructure penetration testing and Active Directory/Windows security assessments. 6. SOC Support – Threat Hunting & Advanced Investigations
· Work closely with the SOC team to support proactive threat hunting across SIEM, XDR/EDR, network, endpoint, identity, and cloud telemetry.
· Develop and execute threat-hunting hypotheses based on emerging threats, MITRE ATT&CK; techniques, threat intelligence, observed attacker TTPs, and organizational risk.
· Support advanced investigations involving suspicious activity, compromised accounts, malware, lateral movement, privilege escalation, persistence, and potential data compromise.
· Correlate penetration-testing findings and attack paths with SOC detections to identify monitoring gaps and improve detection coverage.
· Provide technical advisory to SOC analysts during complex investigations and help validate attack techniques through controlled simulations.
· Recommend current detection use cases, telemetry requirements, investigation playbooks, and threat-hunting queries based on offensive-security findings.
· Participate in incident investigations as a subject-matter expert for exploitation, attacker behavior, and attack-path analysis.
· Conduct purple-team style validation where required to verify whether SOC controls can detect and respond to realistic attack techniques. 7. Security Advisory & Consulting
· Provide security advisory to application, infrastructure, cloud, DevOps, SOC, and security teams.
· Review architecture, security controls, and proposed remediation approaches from an attacker perspective.
· Advise on security improvements based on penetration-testing findings, threat intelligence, incident observations, and emerging attack techniques.
· Support security design reviews and provide practical recommendations that balance security and business requirements. 8. Automation, Scripting & Exploit Development
· Develop scripts and automation to improve penetration-testing and security-investigation efficiency.
· Create custom tools, payloads, PoCs, and exploit scripts where required.
· Use Python, PowerShell, and Bash for security automation, testing, and investigation support.
· Understand exploit code and modify publicly available PoCs safely for authorized assessment activities. 9. Reporting & Client Communication
· Prepare high-quality technical and executive-level penetration-testing reports.
· Document vulnerability details, evidence, business impact, risk, attack paths, PoCs, and remediation recommendations.
· Present findings to technical teams, security leadership, and business stakeholders.
· Conduct client walkthroughs, remediation discussions, and vulnerability-closure/retest sessions. 10. Individual Contributor Expectations
· Own penetration-testing engagements independently with minimal supervision.
· Define methodology, testing approach, effort estimates, dependencies, and timelines.
· Handle complex and ambiguous security problems and take ownership of deliverable quality.
· Mentor junior testers through technical guidance and knowledge sharing.
· Improve internal PT methodologies, checklists, tooling, automation, and reporting standards.
· Contribute to security research, labs, offensive-security capability development, and service improvement. Required Technical Skills Web & API Security
