About the role

BrightMart Solutions is launching a security hardening initiative for its cloud‑hosted retail platform. We need a Flutter Mobile Developer to build and secure the new "VaultGuard" module, which will enforce end‑to‑end encryption for user data on iOS and Android devices. The work focuses on integrating security SDKs, performing code reviews, and delivering a hardened mobile client within a tight sprint.

Key responsibilities

• Implement the VaultGuard UI using Flutter 3.x, adhering to Material Design and platform‑specific accessibility guidelines.
• Integrate OWASP Mobile Security Project recommendations and the Firebase App Check SDK for runtime protection.
• Write unit and integration tests with Mockito and integration_test, achieving 80% coverage before each milestone.
• Collaborate with the cloud security team to consume hardened REST APIs secured by mutual TLS.
• Perform static analysis using SonarQube and address identified vulnerabilities in the codebase.
• Document security configurations and hand‑off notes for the release engineering team.

Must-have skills

• 3+ years of Flutter development experience on both Android and iOS.
• Proficiency with Dart, state‑management (Riverpod or Bloc), and RESTful API consumption.
• Hands‑on experience securing mobile apps (encryption, secure storage, token handling).
• Familiarity with CI/CD pipelines (GitHub Actions or Bitrise) for Flutter builds.
• Ability to write automated tests and conduct code reviews.

Nice to have

• Experience with Firebase App Check or similar security SDKs.
• Knowledge of cloud‑native security tooling (AWS KMS, GCP Secret Manager).
