Optimize the Player Experience: Profile, troubleshoot, and optimize game performance, stability, memory usage, and responsiveness across a wide range of mobile devices, ensuring a smooth and high-quality player experience. Build for Mobile: Develop and optimize experiences for iOS and Android, balancing technical constraints, device fragmentation, performance, and platform-specific requirements to deliver a reliable mobile product. Solve & Improve: Identify technical bottlenecks, investigate complex problems, and implement practical solutions that continuously improve the quality, performance, and scalability of the game. Accelerate with AI: Leverage AI tools and emerging technologies to improve development velocity across coding, debugging, research, documentation, and problem-solving, while maintaining strong engineering judgment and quality standards. Partner Cross-Functionally: Work closely with the CTO, Product, and other disciplines to translate product goals and player needs into effective technical solutions and help shape decisions across the game. Elevate Engineering Quality: Establish and maintain clean, maintainable code and contribute to engineering practices, architecture, and processes that enable the team to move quickly without sacrificing quality or long-term scalability. Enable the Team: Share knowledge, contribute to code reviews, and mentor other engineers when appropriate, helping build strong technical practices and a collaborative engineering culture. Adapt & Deliver: Navigate evolving priorities and requirements while maintaining execution momentum and ensuring high-quality features and releases are delivered on time. What you’ll bring to the team: Experience: 6+ years of professional game development experience, including hands-on experience building and shipping mobile games. C# & Unity: Strong expertise in Unity3D and C#, with a deep understanding of game development patterns, architecture, and engineering best practices. Mobile Expertise: Proven experience developing and optimizing Unity games for iOS and Android, with a strong understanding of mobile-specific technical and performance considerations. Performance: Strong experience profiling and optimizing mobile game performance, with the ability to identify bottlenecks and make informed technical trade-offs. Ownership & Autonomy: A strong sense of ownership and the ability to take a problem from identification through solution and delivery without needing constant direction. Problem-Solving: A practical, analytical approach to technical challenges, with the curiosity and initiative to investigate problems, identify root causes, and find effective solutions. Adaptability: Comfortable working in a fast-changing environment where priorities and requirements evolve, and able to make progress even when not everything is perfectly defined upfront. AI Proficiency: Comfortable using AI tools such as Claude, ChatGPT, or similar technologies as part of your everyday development workflow. Communication & Collaboration: Strong communication skills and the ability to work effectively with technical and cross-functional partners in English.
