Senior Mobile Security Engineer

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.
