About The Position

We are seeking a Staff Software Engineer, based either in Montreal, Canada or working remotely within the US East Coast time zone, to join a newly established engineering team responsible for delivering Unity platform support for an Android-based ecosystem encompassing mobile, laptop, and hybrid form factors. We enable Unity developers to seamlessly deploy titles across these devices while fully leveraging their unique hardware and software capabilities, including optimized display utilization, native input integration, and platform-specific services. The team is also charged with researching and implementing runtime optimizations to improve startup performance and execution efficiency across both entry-level and high-performance devices. This will be accomplished by establishing performance benchmarks, collaborating with internal and external domain experts to conduct deep performance analyses of the Unity engine on the platform, and partnering with key stakeholders to deliver verified enhancements. This is a highly technical individual contributor role with substantial responsibility for guiding architectural decisions and engineering methodologies. The role involves close cross-functional collaboration with engineering groups across platforms, core engine development, editor workflows, and the graphics system. Candidates must possess extensive domain expertise in C++, C#, and Android systems programming, demonstrated technical leadership capabilities, and a proven ability to mentor engineering staff while leading strategic initiatives with cross-organizational impact.

Requirements

Extensive background in Android systems programming, supported by advanced proficiency in C++, C#, and Java/Kotlin.
Demonstrated success in architecting, building, and deploying large-scale platform or runtime systems.
Comprehensive understanding of computer architecture, memory hierarchies, cache mechanics, and CPU/GPU interaction models.
Proficiency in asynchronous execution and multithreaded software architecture.
Proven capacity to analyze, comprehend, and navigate large and complex software codebases.
Documented history of leading cross-functional technical initiatives and shaping engineering direction.
Advanced diagnostic, debugging, and performance profiling competencies.

Nice To Haves

Experience in game engine architecture and development (Unity, Unreal Engine, or proprietary engines).
In-depth understanding of C# and managed runtime environments.
Active contributions to open-source software initiatives or published technical literature.
Familiarity with real-time 3D rendering methodologies and modern graphics APIs, including Vulkan.
Sound engineering judgment regarding the integration and application of artificial intelligence tools within software development workflows.

Responsibilities

Lead cross-team technical initiatives, driving consensus on architectural designs and implementation strategies.
Profile, analyze, and identify optimization opportunities across the stack, partnering with stakeholder teams to develop and deploy performance improvements.
Provide technical mentorship and guidance to engineers across the organization, promoting rigorous software engineering standards and code quality.
Contribute to the strategic definition and roadmap planning of platform engineering initiatives.
Author comprehensive technical documentation and actively participate in design review processes.
Investigate and resolve complex, system-level issues spanning multiple software subsystems.
