Middle/Senior Unity Developer R&D

As a Middle/Senior Unity Developer R&D, you’ll help evolve a live mobile game by building new gameplay systems, LiveOps features, and scalable technical solutions.
You’ll work across the full development lifecycle, from implementing new mechanics to improving architecture, performance, stability, and maintainability.
A strong focus of the role is on modern AI-assisted development, with opportunities to integrate AI agents into real production workflows and automate recurring engineering tasks.
You’ll investigate real-world production issues using telemetry and profiling data, ensuring a smooth experience across a wide range of mobile devices.
The role also offers significant technical ownership, including participation in architectural decisions, code reviews, optimization initiatives, and development practices.
You’ll collaborate closely with other technical and product-focused team members while contributing ideas that can improve both engineering efficiency and the game itself.
This is an R&D-oriented opportunity for a developer who enjoys solving complex technical problems, experimenting with new tools, and seeing their work make a measurable product impact.

• 3+ years of commercial experience with Unity and C#, including experience working on released mobile games and supporting projects through LiveOps rather than only developing them prior to launch.
• Strong understanding of Unity project architecture, including design patterns, dependency injection with tools such as Zenject or VContainer, asynchronous programming with UniTask, Unity lifecycle, memory management, and garbage collection.
• Practical experience with AI development agents such as Cursor, Claude Code, or comparable tools, including the ability to decompose tasks, provide appropriate context from large codebases, and validate generated code.
• Experience with MCP, including Unity MCP or similar approaches, as well as skills, rules, and agent-instruction workflows.
• Ability to document team development practices in a way that allows AI agents to reproduce them consistently.
• Hands-on experience with Addressables, Asset Bundles, CDN delivery, Remote Configs, versioning, caching, and fallback scenarios.
• Strong profiling and optimization experience across Android and/or iOS, including investigation of ANRs, crashes, OOM issues, and production performance regressions.
• Understanding of low-end Android devices, device fragmentation, and mobile build-size optimization.
• Experience integrating third-party SDKs for advertising, analytics, and in-app purchases.
• Familiarity with Git workflows, code review practices, and CI/CD.
• Ability to take a complex technical problem from symptom identification through root-cause analysis, solution implementation, and verification of the outcome.
• Understanding of product metrics such as retention, CPI, and LTV.
• Strong analytical and problem-solving skills, with a proactive approach to technical challenges.
• Ability to work independently, take ownership of technical decisions, and communicate complex engineering topics clearly.
• Experience in an R&D-oriented environment is advantageous.
• Professional Ukrainian language proficiency is expected.
