The Role
As our Software Engineer (Game Development), you will help shape the future of interactive physical gaming and realize Nex's very bold vision: "Create the best motion games for hundreds of millions of people to play on".
You will be a key contributor to our global content infrastructure, architecting the core systems, gameplay features, and presentation layers that allow our games to reach international audiences. You will work across the Unity stack—from implementing engaging gameplay mechanics to building scalable, performant, and "pixel-perfect" UI domains.
You will partner closely with Game Designers, UI Artists, and other engineers to deliver world-class experiences across our growing library of titles, such as GoKeeper, Tennis Smash: Racketville, HomeRun Heroes: StarStrikers, Bowling Strike, and Basketball Knockout.
What You'll Do
- Architect and implement foundational game systems, core gameplay mechanics, and robust UI infrastructures that power our expanding library of games.
- Partner with Game and UI Designers to translate concepts (from game design documents to Figma prototypes) into highly functional, polished Unity implementations.
- Draft technical strategies for modernizing our existing live titles, refactoring legacy systems to support new features and internationalization.
- Build and maintain shared component libraries and core frameworks, creating performant and responsive systems that work seamlessly across different games.
- Develop custom tools and workflows within the Unity Editor to streamline the process for designers, content creators, and translators, removing friction from the development loop.
- Drive performance optimization across the game client, managing memory usage, draw calls, and asset loading to ensure high performance on all target devices.
- Implement polished animations, micro-interactions, and game logic that make the experience feel alive, responsive, and delightful to the player.
- Participate in code reviews and technical discussions to raise the bar for code quality and maintainability across the team.
Must Have
- 3+ years of professional software development experience.
- Strong proficiency in C# and the Unity ecosystem.
- Solid understanding of Unity engine features, including gameplay scripting, UI systems (uGUI or UI Toolkit), and physics/rendering basics.
- Familiarity with asset management strategies (Addressables or Asset Bundles).
- Experience with asynchronous programming in Unity (UniTask, async/await, or coroutines).
- Ability to write clean, maintainable, and performant code.
Should Have
- A growth mindset and the energy to thrive in a fast-paced, high-growth environment.
- An obsession with code quality and a sense of personal ownership over the product's final polish.
- Experience implementing architectural patterns (MVVM, MVC, MVP, or ECS) to separate game logic from presentation.
- Passion for building scalable frameworks and tools that empower every discipline to deliver their best work efficiently.
- Genuine excitement for deep technical challenges, such as optimizing performance, managing complex state logic, or handling internationalization pipelines.
Nice to Have
- Experience with Localization pipelines (handling string keys, pluralization rules, or tools like Crowdin/I2).
- A love for staying active and healthy, with a passion for helping others do the same.
- An interest in playing games and excitement about game development.
We Offer
- Competitive compensation package.
- Flexible working hours and vacation policy.
- Product-driven culture that treasures talents and individual growth.
- Front-row seat and hands-on experience with cutting edge technologies in the evolving gaming field
