Operating at the forefront of aerospace and space, cybersecurity and digital identity, we're driven by a mission to build a future we can all trust.

In Singapore, Thales has been a trusted partner since 1973, originally focused on aerospace activities in the Asia-Pacific region. With 2,000 employees across three local sites, we deliver cutting-edge solutions across aerospace (including air traffic management), defence and security, and digital identity and cybersecurity sectors. Together, we're shaping the future by enabling customers to make pivotal decisions that safeguard communities and power progress.

Thales CDI (Cyber-Security Products) is hiring a Mobile Engineer (iOS) to build IAM (Identity & Access Management)mobile apps and SDKs. You will help deliver secure, easy-to-integrate authentication experiences where security is non-negotiable.

You will work in a small, high-impact team and use AI responsibly to accelerate delivery-while applying strong engineering judgment and human-led security review in a security-critical environment.

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.
• Owntest 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).
• MaintainCI/CD (e.g., Jenkins, GitLab CI) with SAST, dependency scanning and automated security checks use AI to triage and accelerate remediation.
• EvaluateAI/ML tools and recommend adoption aligned to IAM security and data-handling standards share best practices.
• Addprivacy-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.

Requirements:

• Degree in Computer Engineering, Information Security, Electronics or related field.
• 5+ years of professional mobile development experience.
• iOS (Swift, SwiftUI/UIKit) 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.

Other Information:

• Working Location: One North

• Working Hours: Monday - Friday, 9am - 6pm
