Specialist C++ Engineer

Magnopus is on a mission to bridge the physical & digital divide with our groundbreaking set of client applications powered by the Connected Spaces Platform: an open-source SDK that is paving the way for the future of the spatial internet. 

Through engine interop APIs, creators can build and publish spatial experiences that are as interconnected and accessible as the web pages of today. This innovative platform ensures seamless experiences across multiple technologies, allowing users to navigate through diverse digital and physical spaces without the barriers of switching identities, devices, or interfaces.

We are seeking an experienced Senior C++ Engineer to work on the core library of the Connected Spaces Platform. This role is for a systems engineer who is genuinely excited at the prospect of working across multiple domains and technologies, to deliver value to our internal teams and external clients. We’re looking for an independent thinker who can help define the work that needs to be done. 

The successful candidate will be able to navigate a technically broad system consisting of multiple language runtimes, and will find success managing this through a focus on quality and continual improvement. You’ll play a key role in shaping how the platform evolves - from planning and designing solutions to guiding best practices.

We collaborate asynchronously across distributed teams and value written, transparent communication and autonomy. You’ll be joining a team that values clarity, trust, and momentum - where everyone understands their dependencies and takes initiative to keep things moving in the right direction.

By joining Magnopus, you’ll not only work on enhancing the platform’s capabilities, but also contribute to our vision of building an open and accessible spatial internet for all.

We don’t expect anyone to tick every box below - if you bring a strong mix of skills, curiosity, and the drive to keep learning, we’d love to hear from you.

• High level of proficiency with modern C++ (17 or higher).
• Comprehensive knowledge of best practices, design patterns, and architectural principles essential for C++ library development.
• Proven, hands-on experience targeting multiple operating systems such as Windows, Linux, MacOS and iOS.
• Ability to independently plan and deliver solutions, including scoping and owning features.
• Ability to understand and respond to the needs of dependent clients and teams, including adapting C++ patterns to the idiomatic best practices of other languages such as C# and JS or TS.
• A self-critical approach to work quality and a drive to improve codebases and address technical debt.
• Practical experience integrating RESTful and or GraphQL APIs.
• Ability to design usable and maintainable API surfaces.
• Strong communication skills that support clear and effective collaboration across technical levels.
• Experience using and maintaining build systems for cross platform C++ projects and their dependencies.
• Familiarity with realtime networking.
• Experience using and maintaining CI and CD pipelines for complex multi platform build scenarios.
• A focus on delivering stability through code that is inherently testable.

• Experience with embedded scripting runtimes.
• Experience with web technologies (Emscripten/WASM).
• Experience with Unreal Engine and/or Unity.
