About The Position

Level is a learning technology company that builds interactive, standards-aligned practice to support students, educators, and parents. The Senior Client Platform Engineer owns how Level’s Godot-based educational games are built, delivered, and run on one or more target platforms, ensuring they perform well and feel native across devices such as Chromebooks, iPads, and web browsers. The role requires deep hands-on knowledge of the CPU, GPU, and platform-specific requirements of at least one specialty platform, along with mentoring and technical leadership.

The engineer owns platform delivery end to end, from builds and packaging through signing, distribution or store requirements, release, and live updates. They design and maintain shared abstractions between game code and platform-specific windowing, input, file-system, and device services; manage lifecycle events and memory pressure; and develop capability detection, quality settings, scalability tiers, and graceful fallbacks. They profile and optimize performance, build native plugins and bindings, automate platform CI and device testing, document constraints, influence technical decisions, and mentor engineers.

Level is hiring across iOS, Android/Chromebook, Web, Desktop (Windows, macOS, Linux), Performance, and Generalist specializations. Candidates need depth in at least one area. The company will route applicants to the track that best fits their strengths.

Requirements

• At least 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 a specialty platform and their impact on real-time application performance.
• Strong C++ or C# skills and fluency in the native languages of the specialty platform, such as Swift or Objective-C, Kotlin or Java, JavaScript or TypeScript, or Rust.
• Hands-on ownership of platform build, packaging, signing, and release for a shipped product, including store submission or distribution.
• Experience with the application lifecycle and system services of the 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; Godot or a comparable engine is suitable.
• Track record of mentoring mid-level engineers and influencing technical decisions on a team.
• Clear written and verbal communication, including the ability to explain platform constraints to non-specialists.
• Deep expertise in at least one of the platform specializations listed in the posting.

Nice To Haves

• Experience with Godot, including custom builds, export templates, or GDExtension.
• Experience building platform abstraction layers or cross-platform runtime frameworks.
• Experience with device capability detection, automatic quality settings, or dynamic scalability systems.
• Experience targeting low-end or school-issued hardware, including Chromebooks.
• Experience with CI/CD for multi-platform builds and automated device testing.
• Shipped titles or apps on one or more app stores or web platforms.
• Interest in educational technology and building products used every day by students and teachers.

Responsibilities

• Own end-to-end delivery of Level’s games on one or more specialty platforms, including builds, packaging, signing, distribution or store requirements, releases, and live updates.
• Design and maintain a shared platform abstraction layer for windowing, input, file-system access, and device services.
• Handle application lifecycle events, including suspend and resume, backgrounding, orientation and window changes, permissions, interruptions, and memory pressure.
• Build device capability detection, automatic quality settings, scalability tiers, and fallback strategies for a broad range of hardware.
• Profile and optimize CPU, GPU, memory, load-time, and battery performance using platform-native tools, in collaboration with graphics and gameplay engineers.
• Write and maintain native plugins and bindings connecting Godot to platform services.
• Automate platform builds, packaging, and device testing, and maintain a representative device matrix to catch regressions.
• Influence technical decisions, identify platform risks early, and document platform constraints for gameplay, graphics, and product teams.
• Mentor mid-level and associate engineers in platform fundamentals and engineering practices.
