Limit Break is looking for an exceptional Game Developer to help build ambitious, high-quality mobile games with a team that moves fast and thinks deeply about the player experience.
As a strong individual contributor, you will own meaningful gameplay and technical systems, work through complex engineering challenges, and collaborate closely with talented developers, artists, designers, and product leaders.
This role is for someone who wants to grow through responsibility, challenge, and impact. At Limit Break, you’ll work on problems that demand sharp judgment, technical depth, and a high standard of execution.
Join a team where strong engineers are trusted, challenged, and given room to do the best work of their careers.
Responsibilities: What you’ll do
- Design, implement, and maintain robust Unity/C# gameplay, UI, and client systems for a live mobile game.
- Build modular, data-driven features that respond safely to live configuration, remote content, and backend-driven state.
- Own features from design through implementation, polish, release, telemetry, debugging, and post-launch iteration.
- Collaborate closely with design, art, backend, QA, and production to turn ambiguous feature goals into reliable player-facing experiences.
- Partner with backend engineers on API contracts, client-server flows, error handling, version compatibility, and production diagnostics.
- Improve client architecture, performance, tooling, and engineering quality through thoughtful code reviews and maintainable system design.
- Diagnose and fix production issues across devices, builds, content, networking, and Unity lifecycle edge cases.
Qualifications: Who you are and what you’ve done
- 7+ years professional game development experience, including 4+ years with Unity and C#.
- Shipped multiple games, including at least one Unity title.
- Deep understanding of Unity lifecycle, MonoBehaviours, ScriptableObjects, Prefabs, Addressables, serialization, and asset/content loading.
- Strong C# engineering fundamentals, including async programming, cancellation/cleanup patterns, memory/performance awareness, and maintainable architecture.
- Experience building data-driven or live-service systems that support remote config, content updates, events, or backend-driven behavior.
- Comfortable owning complex features end to end, from ambiguous requirements to polished production behavior.
- Strong debugging instincts for mobile client issues, including logs, crashes, performance, networking, and device-specific behavior. Able to work autonomously while communicating clearly with engineers, designers, artists, QA, and production.
- Has built or shipped at least one game in a small-team environment, taking ownership across multiple major facets of development.
- Proficiency in English.
