About the Team
Navi’s Security Engineering team is responsible for safeguarding our financial ecosystem that powers millions of users across lending, payments, insurance, investments, and UPI. We work closely with product, engineering, fraud prevention, and infrastructure teams to ensure the integrity of mobile devices, applications, and transactions.
Given the critical nature of fintech platforms, our security engineers proactively simulate real-world attack scenarios, build advanced detection systems, and strengthen mobile runtime protections. The team focuses heavily on mobile runtime security, device integrity, anti-tampering systems, and adversarial threat modelling.
About the Role
As a SDE III , you will be responsible for strengthening the mobile security posture of our Android and iOS applications. This role requires a deep understanding of both offensive (red team) and defensive (blue team) mobile security techniques.
You will actively analyze how mobile applications and devices can be compromised — including rooted/jail broken devices, emulators, hooking frameworks, runtime manipulation, and reverse engineering — and design strong countermeasures using runtime protection, device intelligence, and behavioral detection.
You will collaborate closely with engineering, fraud prevention, and platform teams to continuously improve device risk detection and runtime security.
Key Responsibilities
Design and implement mobile runtime security controls to protect Android and iOS application
Identify and mitigate threats such as rooted and jail broken devices, emulators and virtual environments, hooking frameworks (Frida, Xposed, Substrate), runtime tampering, and code injection
Develop and improve device integrity detection mechanisms using system signals, kernel indicators, file system checks, hardware signals, and behavioral telemetry
Perform red-team style mobile attack simulations to identify weaknesses in application security
Build defensive systems to detect and prevent runtime tampering, binary modification, dynamic instrumentation, screen overlay attacks, and OTP/SMS interception techniques
Work closely with fraud prevention and backend risk systems to convert device signals into actionable risk controls
Conduct mobile application security assessments and penetration testing
Collaborate with mobile engineering teams to embed security best practices into the application lifecycle
Investigate production security incidents related to device compromise, reverse engineering, or mobile fraud
Continuously research new attack vectors and improve detection mechanisms against evolving threat
Must
Have 4+ years of experience designing and building mobile RASP (Runtime Application Self-Protection) capabilities for Android and/or iOS applicat
ions.
Deep understanding of device compromise techniques including rooting, jail breaking, emulator environments, hooking frameworks, and runtime instrumenta
tion.
Hands-on experience with tools such as Frida, Objection, Xposed/LSPosed, Burp Suite, JADX, Ghidra, IDA, MobSF or similar t
ools.
Experience implementing or working with mobile RASP or mobile threat defense solut
ions.
Strong understanding of mobile application reverse engineering techni
ques.
Ability to work across both offensive (red) and defensive (blue) security dom
ains.
Programming experience in Java/Kotlin, Swift/Objective-C, or similar langu
ages.
Experience in fintech, payments, or banking security environments, with prior experience working with or integrating mobile RASP / mobile threat defense platforms
