This is a pivotal senior role placing you on the front lines of protecting millions of users from sophisticated mobile fraud and adversarial attacks. As a Mobile Security Engineer (Forensics), you will design, build, and operate systems that investigate and attribute malicious activity across Android and iOS.

You will work across the full forensic lifecycle—from secure on-device signal collection and evidence preservation to large-scale analysis, attacker behavior reconstruction, and incident response. Operating at the intersection of mobile engineering, security, and data, you will uncover emerging fraud and spoofing techniques, strengthen detection systems, and help protect users at scale.

Key Responsibilities

• Analyze large-scale datasets and fraud incidents to uncover attack patterns, fraud clusters, and evolving adversarial behavior, including reconstructing attacker techniques and execution paths.
• Partner with the mobile development team to design and implement mobile SDK components to securely collect forensic-grade signals, enabling attribution of location spoofing, emulator abuse, rooted/jailbroken environments, and other environment manipulation.
• Execute and lead deep technical research into emerging mobile fraud and evasion techniques, translating findings into actionable forensic indicators.
• Build and mature end-to-end incident response capabilities across the stack, partnering with Data Science and ML teams to translate forensic insights into technical features, rules, and detection logic.
• Provide technical guidance and mentorship to junior engineers on best practices in mobile security, forensics, and data analysis.

Who You Are

• Deep passion for investigating security incidents, hunting attackers, and uncovering sophisticated fraud, spoofing, and abuse patterns, with a strong curiosity for understanding how adversaries operate and evade defenses.
• 4+ years of progressive, hands-on experience in security, forensics, or offensive security, with a proven track record of delivering high-impact security solutions.
• Bachelor's degree in Security Engineering, Computer Science, or Computer Engineering is required; advanced technical degree is a plus.
• Demonstrated expertise and practical application of data analysis (SQL, data modeling, feature extraction) in security investigations.
• Familiarity with data science concepts and the role of ML in detection systems
• Strong English communication skills, with the ability to clearly document findings and explain technical investigations to both technical and non-technical audiences.

Plus point

• Experience with mobile development (Android, iOS, or cross-platform).
• Familiarity with mobile security and forensics, including: Root / jailbreak detection and evasion techniques
• Emulator and virtualized environment detection
• Location spoofing and geolocation integrity validation
• Device attestation, TEE, Secure Enclave, and hardware-backed security
• Interest in incident response, threat research, or adversarial analysis.
