Sr Systems Engineer

About the job

Smore Labs is a recently funded, VC-backed stealth startup building a mobile UGC game platform where kids use AI to create, learn, and share within one unified experience. We’re seeking a Senior Systems Engineer to build the glue that powers Unity on mobile—core systems, native integrations, tools, and AI—so the team can ship fast, safe, high-quality systems.

Responsibilities:

• Design, build, and maintain core Unity systems that support gameplay, UI, voice, and AI features across iOS and mobile devices.
• Own platform-facing integration work, including iOS-specific behavior, native SDKs, permissions, audio routing, lifecycle handling, and device constraints.
• Implement and evolve voice and AI runtime systems, including capture, playback, processing, and safe integration with LLM-driven features.
• Partner with gameplay, design, UI/UX, and backend to define system-level contracts and tooling that unblock rapid iteration and live ops.
• Lead performance and stability work: profile with Unity tools and Xcode Instruments, reduce memory and frame time, and fix device-specific issues.

Essential Skills and Experience:

• 5+ years in systems or engine-side game development with shipped Unity mobile titles; strong C# and C++ plus working knowledge of backend systems.
• Proven track record integrating native SDKs and OS features on iOS and Android via Unity plug-ins, with strong debugging of platform edge cases.
• Experience working with AI systems for development and production, connecting AI services into essential game and tool systems
• Deep mobile performance literacy: profiling, memory and allocation control, GPU/CPU analysis, and practical optimization for Unity on iOS.
• Clear communication and collaboration across disciplines; comfortable defining APIs, writing concise docs, and supporting build and release workflows.
