About the Role

Level is looking for a Senior Client Platform Engineer to own how Level's Godot-based educational games ship and run on one or more target platforms. You will ensure each student's experience feels native and performs well across various devices, from school-issued Chromebooks to family iPads to browser tabs. You'll leverage deep knowledge of CPU, GPU, and platform-specific requirements, and mentor other engineers.

Responsibilities

Own delivery of Level's games on specialty platform(s) end to end, including build, packaging, signing, store or distribution requirements, release, and live updates
Design and maintain the shared layer that isolates game code from platform differences in windowing, input, file system access, and device services
Handle suspend and resume, backgrounding, orientation and window changes, permissions, interruptions, and memory pressure
Build device capability detection, automatic quality settings, scalability tiers, and graceful fallbacks
Use platform-native profiling tools to find CPU, GPU, memory, load-time, and battery bottlenecks, and work with graphics and gameplay engineers to fix them
Write and maintain native plugins and bindings, such as GDExtension, JNI, Swift or Objective-C, and JavaScript interop
Automate builds, packaging, and device testing for your platform, and maintain a representative device matrix
Influence technical decisions, flag platform risk early, and document platform constraints
Actively mentor mid-level and associate engineers on platform fundamentals and good engineering practice

Requirements

5+ years of professional software engineering experience, including shipped production software on at least one of iOS, Android or ChromeOS, Web, Windows, macOS, or Linux
Deep, demonstrated expertise in the CPU, GPU, memory, and thermal characteristics of your specialty platform and how they shape real-time application performance
Strong C++ or C# skills, plus fluency in the native languages of your specialty, such as Swift or Objective-C, Kotlin or Java, JavaScript or TypeScript, or Rust
Hands-on ownership of platform build, packaging, signing, and release, including store submission or distribution, for a shipped product
Experience with the application lifecycle and system services of your platform, including windowing, input, file system access, permissions, and interruptions
Proficiency with platform profiling and debugging tools, such as Xcode Instruments, Android Studio Profiler, Perfetto, browser DevTools, PIX, or RenderDoc
Familiarity with game engine or real-time application architecture, ideally Godot or a comparable engine
Track record of mentoring mid-level engineers and influencing technical decisions on your team
Clear written and verbal communication, with the ability to explain platform constraints to non-specialists
Experience with Godot, including custom builds, export templates, or GDExtension (Nice to Have)
Experience building platform abstraction layers or cross-platform runtime frameworks (Nice to Have)
Experience with device capability detection, automatic quality settings, or dynamic scalability systems (Nice to Have)
Experience targeting low-end or school-issued hardware, including Chromebooks (Nice to Have)
Experience with CI/CD for multi-platform builds and automated device testing (Nice to Have)
Shipped titles or apps on one or more app stores or web platforms (Nice to Have)
Interest in educational technology and in building products that students and teachers use every day (Nice to Have)
