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

Level; Austin (CO); On-site; USD 150,000 - 190,000; Full time

Job summary

Level is seeking a systems-oriented engine engineer to help build and evolve our robust technology platform supporting a broad range of devices, including web, desktop, Chromebooks, iPads, and mobile.

We are building our own technology stack below the gameplay layer, and we are looking for engineers who are comfortable working in engine internals, modifying engine source, and making architectural decisions that affect the entire platform.

Qualifications

• Strong professional C++ experience.
• 7+ years of experience on game engines, real-time systems, runtime infrastructure, platform technology, or other low-level systems.
• Direct experience 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.

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.
