Security Researcher

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

This is an opportunity to join a Product Security team focused on cutting-edge mobile cybersecurity research and advanced threat defense.

• Research emerging threats affecting mobile operating systems and applications, including rooting/jailbreaking, app tampering, runtime tampering, and techniques used to conceal malicious modifications.
• Conduct reverse engineering, vulnerability research, exploitation, and mitigation work to develop effective mobile security protections.
• Perform penetration testing and security assessments of mobile products and applications, identifying vulnerabilities and recommending practical defenses.
• Develop scripts, tooling, and attack/defense techniques for mobile devices and applications to accelerate security research and testing.
• Create customer-facing security demonstrations that clearly communicate attack scenarios, vulnerabilities, and corresponding defensive mechanisms.
• Contribute to security solution architectures spanning mobile devices, applications, and networked components, including authentication technologies such as OAuth2 and FIDO2.
• Research and assess cryptographic protocols and algorithms when required as part of broader security architecture and product development.
• Take ownership of selected research and development projects, driving them from investigation through implementation and delivery.
• Mentor and provide technical guidance to junior security researchers, while contributing to a culture of quality, creativity, and continuous improvement.
• Collaborate closely with the wider Product Security team to develop innovative approaches to emerging mobile security challenges.

• 5+ years of relevant experience in security research, application security, mobile security, vulnerability research, penetration testing, or a closely related field.
• Strong understanding of operating system internals across one or more platforms such as Android, iOS, HarmonyOS Next, Linux, or comparable systems.
• Solid knowledge of mobile application development and security, with practical familiarity with rooting/jailbreaking, runtime tampering, app tampering, and related evasion techniques.
• Hands-on experience with security research and reverse-engineering tools such as Frida, Theos, Ghidra, and IDA Pro.
• Familiarity with web application security and VAPT tools such as Burp Suite.
• Ability to understand how security tools and methodologies work internally and use that knowledge to develop creative, customized approaches rather than relying solely on standard workflows.
• Strong understanding of threat modeling and familiarity with at least one established threat-modeling framework.
• Experience with scripting or building custom tools to support security research, testing, attack simulation, or defensive development.
• Strong analytical and critical-thinking abilities, with a systematic and methodical approach to research and testing.
• Demonstrated ownership of technical projects, with the ability to work independently and make progress with minimal supervision.
• Excellent attention to detail and a strong commitment to quality, security, and technical rigor.
• Strong communication and interpersonal skills, with the ability to collaborate effectively and mentor less-experienced researchers.
• A proactive, adaptable, and highly driven mindset suited to a dynamic and rapidly evolving technical environment.
• A degree in Computer Science, Information Systems, Mathematics, or a related discipline is preferred, particularly with relevant cryptography coursework.
• Information security, ethical hacking, or security architecture certifications are a plus.

• Fully remote position based in India.
• Full-time opportunity within a specialized Product Security team.
• Opportunity to work on advanced mobile cybersecurity research across Android, iOS, and HarmonyOS Next.
• Exposure to reverse engineering, vulnerability research, exploitation, penetration testing, cryptography, and security architecture.
• High level of technical ownership and the opportunity to lead selected research initiatives.
• Opportunity to mentor junior researchers and contribute to the evolution of security practices.
• Fast-paced, innovative environment with opportunities to develop new security tools, techniques, and solutions.
• Opportunity to work on security technologies protecting large-scale digital ecosystems and users globally.
