This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Offensive Security Engineer based in Bangalore, India.

Are you an experienced cybersecurity professional passionate about ethical hacking, adversarial security testing, and strengthening enterprise security? This role offers an exciting opportunity to proactively identify security weaknesses and improve the resilience of complex digital environments. You will lead penetration testing, red team engagements, and adversary simulation initiatives across applications, cloud infrastructure, networks, and enterprise systems. Working closely with Security Operations, Threat Intelligence, Vulnerability Management, Application Security, and Engineering teams, you will help transform security findings into actionable improvements. You will also contribute to the development of advanced testing methodologies, automation capabilities, and continuous security validation practices. This is an opportunity to influence enterprise-wide security strategy, mentor technical professionals, and make a measurable impact in a collaborative, technology-driven environment.

Penetration Testing and Security Assessments: Plan, coordinate, and conduct authorized internal and external security assessments across web and mobile applications, APIs, cloud environments, networks, and infrastructure. Evaluate application and infrastructure security to identify vulnerabilities, assess potential business impact, and recommend appropriate remediation measures. Red Team and Purple Team Operations: Design and coordinate authorized red team engagements and adversary simulation exercises to evaluate organizational security resilience. Collaborate with Security Operations Center (SOC), Threat Intelligence, Threat Hunting, and Detection Engineering teams to assess detection capabilities and strengthen incident response readiness. Security Research and Vulnerability Assessment: Identify, validate, and assess security weaknesses, including combinations of vulnerabilities that may create significant business risks. Evaluate findings in controlled and approved environments, documenting their potential impact and providing actionable recommendations. Adversary Simulation: Apply knowledge of real-world threat actor behaviors and the MITRE ATT&CK framework to assess organizational defenses and improve security monitoring and response capabilities. Findings Management and Remediation: Review and validate security findings, prioritize vulnerabilities according to exploitability and business risk, and coordinate remediation activities with engineering teams. Track remediation progress, facilitate follow-up assessments, and ensure agreed security improvements are completed within established service-level agreements. Security Tooling and Automation: Develop and maintain approved security testing scripts, tools, and automation solutions to improve assessment efficiency and scalability. Contribute to the implementation and evaluation of continuous security testing and automated security validation platforms. Reporting and Stakeholder Communication: Prepare comprehensive technical reports and executive-level summaries that translate security findings into understandable business risks and recommendations. Communicate assessment results to technical teams, Governance, Risk and Compliance (GRC), Audit, and senior leadership. Incident Response and Threat Hunting Support: Provide offensive security expertise to incident response and threat hunting activities, helping teams understand potential attack scenarios and strengthen defensive strategies. Continuous Improvement and Mentorship: Develop repeatable security assessment methodologies, operational playbooks, and performance metrics to improve the maturity of the offensive security program. Mentor junior security engineers and contribute to knowledge sharing, technical development, and continuous improvement across the security organization.
