Senior Mobile Software Engineer (iOS / Android), Identity & Security

As a Senior Mobile Software Engineer, you’ll build secure, high-performance mobile applications focused on identity, authentication, and enterprise security.
You’ll architect and deliver native iOS and Android features using Swift and Kotlin across authentication, password management, and identity verification products.
The role combines deep mobile engineering with security-sensitive integrations such as biometrics, secure storage, autofill, and modern authentication protocols.
You’ll work closely with backend and platform teams to build resilient experiences that protect enterprise identities at scale.
Quality is central to the role, with ownership of automated testing, release pipelines, telemetry, troubleshooting, and production reliability.
You’ll also help shape AI-assisted engineering practices while mentoring other engineers and contributing to technical design decisions.
Working remotely within India, you’ll join a distributed engineering environment focused on solving complex technical and security challenges.
