Job summary

Talent Corner Hr Services invites a talented mobile developer to join our team focused on building and extending native mobile SDKs for banking and fintech apps. You will implement device integrity checks, privacy-conscious telemetry and secure session signals to prevent tampering.

You will work across Android (Kotlin/Java) or iOS (Swift), collaborate with backend and identity teams, and ship versioned SDK releases with documentation and sample apps for developers.

Qualifications

• Strong Android development in Kotlin/Java or iOS development in Swift.
• Understand app lifecycle, permissions, background limits, threading and networking.
• Solid programming fundamentals, Git and interest in mobile security and reverse engineering.
• Freshers should demonstrate native mobile work through projects, internships or published apps.
• Proficiency with agentic AI coding tools, with the ability to review, test and take ownership of generated code.

Responsibilities

• Implement device and app integrity checks for rooted/jailbroken devices, emulators and tampering; add remote-access and screen-sharing indicators where OS permits; validate findings against legitimate devices to reduce noisy risk indicators.
• Build privacy-conscious telemetry for touch, typing cadence and navigation within the host app; define event schemas, batching and retry behaviour with backend engineers.
• Extend SIM binding and SIM-change signals; integrate platform attestation and secure request signing for backend risk assessment.
• Build reliable face/liveness and document capture flows with the identity team; manage permissions, camera errors and network failures; keep callbacks straightforward for client developers.
• Test across devices and OS versions; measure size, latency and battery impact; debug client integrations; ship versioned SDK releases with sample apps and documentation.

Job description

The role

Build and extend our native mobile SDKs for banking and fintech apps. Help turn device, SIM and behavioural signals into useful evidence for account takeover prevention, session trust and secure face/liveness onboarding.

Day-to-day work

• - Implement device and app integrity checks for rooted/jailbroken phones, emulators and tampering; add remote-access and screen-sharing indicators where the OS permits, with clear limitations. Validate findings against legitimate devices to reduce noisy risk indicators.
• - Build privacy-conscious telemetry for touch, typing cadence and navigation within the host app; capture interaction patterns without collecting passwords or typed content. Define event schemas, batching and retry behaviour with backend engineers.
• - Extend supported SIM binding and SIM-change signals; integrate platform attestation and secure request signing so backend teams can assess suspicious sessions.
• - Build reliable face/liveness and document capture flows with the identity team, adding injection-aware integration checks and handling permissions, camera errors and network failures. Keep capture and verification callbacks straightforward for client developers.
• - Test across devices and OS versions, measure size, latency and battery impact, debug client integrations, and ship versioned SDK releases with sample apps and documentation.

What you bring

• - Strong Android development in Kotlin/Java OR iOS development in Swift.
• - Understand app lifecycle, permissions, background limits, threading and networking.
• - Sound programming fundamentals, Git and interest in mobile security and reverse engineering.
• - Freshers should demonstrate native mobile work through projects, internships or published apps.
• - Proficiency with agentic AI coding tools, with the ability to review, test and take ownership of generated code.

Good to have

Experience with both platforms, Play Integrity/App Attest, CameraX/AVFoundation, SDK publishing, or React Native/Flutter bridges.
