Simulation Software & Security Engineer in Crawley

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 DevOps 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.
• Protect proprietary native libraries, sensitive data, and downloaded/runtime content from reverse engineering, tampering, or unauthorized extraction.
• 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.

Required Minimum Qualifications

• Bachelor's degree or higher in engineering, engineering technology, chemistry, physics, mathematics, data science, computer science, or another accredited relevant course of study.
• Very strong modern C/C++ and low-level programming skills, with the ability to produce clear, maintainable, and efficient code.
• Experience developing iOS application security architecture.
• Experience with secure cryptography usage and key management.
• Experience with secure storage on iOS.
