Android Security Engineer for IAM SDKs

Thales; Singapore; On-site; SGD 120,000 - 180,000; Full time

Job summary

Thales is seeking a Mobile Engineer (Android) to build IAM authentication apps and SDKs in Singapore. You will design secure authentication flows, own test strategies for SDKs, and ensure backward-compatible APIs while applying AI responsibly in a security-critical environment.

Join a small, high-impact team delivering secure solutions with a focus on AI-assisted delivery, privacy-conscious telemetry, and secure CI/CD workflows. The role offers a challenging, impact-driven engineering culture.

Qualifications

• Degree in Computer Engineering, Information Security, Electronics or related field.
• 5+ years of professional mobile development experience.
• Android (Java/Kotlin) expertise, including lifecycle, concurrency and memory management.
• AI-assisted development (e.g., Copilot/Claude/Cursor); able to prompt effectively and critically validate/rewrite output for security-sensitive code.
• Ability to apply AI across the SDLC (tests/docs/debug/review) with strong quality and security judgment.
• Experience building and distributing mobile SDKs (API design, versioning, binary distribution, backward compatibility).
• Familiar with mobile security practices/tools: static analysis, secure storage (Keychain/Keystore), certificate pinning and reverse-engineering countermeasures.
• Advantage: IAM and auth protocols (OAuth 2.0, OIDC, FIDO2, certificate-based authentication).
• Self-directed, collaborative engineer with strong trade-off judgment.

Responsibilities

• Design, build and validate mobile apps and SDKs; use AI-assisted tooling to accelerate delivery with mandatory human-led security review.
• Implement secure authentication and identity verification flows (protocol-driven); validate designs against platform threat models.
• Own test strategy for SDKs (unit/integration/UI); use AI to expand coverage while rigorously testing security-critical paths.
• Design clean, well-documented SDK APIs with backward compatibility and minimal binary-size impact.
• Improve the SDLC with pragmatic AI adoption (test generation, review support, debugging and release automation).
• Maintain CI/CD (e.g., Jenkins, GitLab CI) with SAST, dependency scanning and automated security checks; use AI to triage and accelerate remediation.
• Evaluate AI/ML tools and recommend adoption aligned to IAM security and data-handling standards; share best practices.
• Add privacy-conscious telemetry (crash/performance/diagnostics) to support customers without exposing sensitive identity data.
• Contribute to product innovation (prototypes/patents), including AI/ML opportunities that improve security and reduce user friction.
