Senior Engine Platform Engineer - Cross-Platform & AI-Driven

Level AI; Austin (TX); On-site; USD 140,000 - 200,000; Full time

Job summary

Level is seeking a systems-oriented engine engineer to help build and evolve its robust technology platform supporting web, desktop, Chromebooks, iPads, and mobile. The role focuses on engine internals, forked Godot work, and architectural decisions across the platform.

The ideal candidate has 7+ years in game engines or low-level systems, strong C++, and a track record of shipping real-time software. Autonomy and a high-bar engineering culture are expected.

Qualifications

• Strong professional C++ experience.
• 7+ years of experience working on game engines, real-time systems, runtime infrastructure, platform technology, or other low-level systems.
• Direct experience working with and modifying engine source code.
• Experience shipping games or other real-time software products.
• Strong debugging and profiling skills.
• Solid understanding of memory, CPU performance, threading, data layout, and systems-level constraints.
• Experience solving cross-platform issues.
• Demonstrated ability to reason about architecture, not just implement tickets.
• Experience building reusable systems rather than only isolated features.
• Senior or Staff-level technical caliber, with signals such as owning major systems, setting architecture, or leading technical decisions (formal people management not required).

Responsibilities

• Work across engine architecture, runtime systems, memory management, multithreading/concurrency, asset loading and streaming, serialization, and build systems.
• Modify and extend our forked Godot engine source to meet product and platform needs.
• Identify and resolve architectural and performance issues at the engine level.
• Build reusable engine systems and tooling, rather than one-off features, that improve the productivity of gameplay engineers and content creators.
• Solve cross-platform compatibility issues across web, desktop, Chromebooks, iPads, and mobile.
• Profile and optimize for CPU, memory, and general runtime performance.
• Navigate and improve a large, evolving, and sometimes unfamiliar codebase.
• Contribute to engineering practices, mentor other engineers, and act as a go-to resource for engine/platform systems.
• Actively experiment with and adopt AI-assisted development tools to improve engineering workflows.
