Job Description & How to Apply Below

Your responsibilities:

Software engineering and product delivery
Own, modify, and extend a large existing C++ codebase; design, implement, review, and ship maintainable, efficient code.
Deliver feature development, defect fixes, refactoring, performance tuning, and ongoing maintenance across the full software life cycle.
Support platform-specific development and integration across Windows, Linux, and iOS environments.
Develop and maintain cross-platform tooling for code generation, packaging, and deployment.
Apply strong debugging, profiling, memory-management, Multithreading, and performance-optimization practices.

Build, CI/CD, and engineering effectiveness

Build and improve automated build systems and CI/CD pipelines to increase reliability, reproducibility, and developer productivity.
Troubleshoot build failures, reduce build times, and support build caching and distributed build approaches where appropriate.
Partner with Dev Ops and engineering teams to harden source-control, build, signing, packaging, and release processes.

iOS and native security engineering

Design and implement the security architecture for an iOS application containing native C++ components.
Implement runtime protections including integrity checks, jailbreak detection, anti-debugging, and tamper-response behavior.

Define secure, least-privilege interfaces between Unreal Engine and native libraries with robust input validation.

Additional Security Responsibilities

Evaluate security libraries, frameworks, and third-party protection tools using defined technical and operational criteria.
Implement secure cryptography usage, key management, iOS secure storage, cloud authentication, and token handling.
Define security logging and telemetry practices, including appropriate data controls for adversarial-actor detection.
Perform and support static analysis, dynamic analysis, fuzzing, reverse-engineering assessments, and adversarial validation.
Balance security controls with performance, maintainability, usability, and deployment constraints.
