С++ Software Engineer

<h4><strong>About the Team</strong></h4> <div>The Canvas Development Kit team builds the foundational layer that enables internal&nbsp; developers to create powerful, flexible widgets and custom experiences on top of the canvas. Our mission is to improve the developer experience by providing reusable building blocks, clear and well-documented APIs, and tools that reduce the time-to-market and complexity of widget development. We partner closely with feature teams to understand their needs and evolve the platform accordingly.</div> <div>Our primary focus is the Surface engine and Surface framework — a React-like declarative system built in TypeScript and powered by a C++ engine via WebAssembly. Surface handles layout, animation, state management, and event propagation, providing a high-level model for describing interactive behavior on the canvas. It includes a custom reconciler, internal rendering system, and developer-facing APIs designed for composability, performance, and ergonomics. The team works on both the runtime and the authoring model, shaping how interactive content is built across the platform.</div> <h4><strong>About the Role</strong></h4> <div class="sc-ctNHPE jXvaGR"> <div class="sc-ijKRza jzgwkN"> <div>We’re looking for a systems-focused engineer to join the team behind our canvas engine — a modern C++ codebase compiled to WebAssembly and integrated with a TypeScript framework that follows a React-like declarative model. The engine handles layout, animation, interaction logic, and client-side data modeling, forming the core of how interactive content behaves on the canvas.<br><br></div> <div>You’ll contribute to internal systems and developer-facing APIs that power higher-level functionality, working across the C++/TypeScript boundary. This role involves solving deep technical problems, optimizing performance, and evolving architecture — not building UI or product-facing features.<br><br></div> <div>We’re opening this role to increase the team’s capacity for foundational improvements and to support long-term technical evolution. You’ll be part of a small, experienced team focused on performance, correctness, and developer experience at the lowest levels of the stack.</div> </div> </div> <h4><strong>What you’ll do</strong></h4> <ul> <li>Extend and maintain a C++ engine (compiled to WASM) that powers layout, animation, and interaction on a visual canvas used by millions</li> <li>Work across the C++ ↔ TypeScript boundary to optimize performance, memory usage, and integration ergonomics</li> <li>Design internal APIs and primitives that enable teams to build powerful behaviors in a React-like declarative model</li> <li>Solve deep technical challenges around structured content modeling, interaction logic, and engine architecture</li> <li>Investigate subtle bugs and performance issues in a complex, multi-language codebase at scale</li> <li>Collaborate with experienced engineers to evolve critical infrastructure used across the platform</li> <li>Contribute to a platform powering thousands of collaborative sessions daily — high product impact from deep, behind-the-scenes work</li> </ul> <h4><strong>What you’ll need</strong></h4> <ul> <li>Solid experience with C++ or similar low-level languages (e.g. Rust, C, Objective-C, Swift)</li> <li>Understanding of memory models, performance trade-offs, and debugging complex systems</li> <li>Experience with or exposure to declarative UI frameworks (e.g. React, React Native, Flutter, SwiftUI, Jetpack Compose)</li> <li>Basic familiarity with JavaScript and TypeScript</li> <li>Ability to work in a cross-language codebase and navigate C++ ↔ JS/WASM boundaries</li> <li>Comfort working independently on complex technical problems</li> <li>Strong communication skills and ability to collaborate in a remote, asynchronous environment</li> </ul> <h4><strong>What's in it for you</strong></h4> <ul> <li style="font-weight: 400;">Competitive equity package</li> <li style="font-weight: 400;">Health insurance for you and your family</li> <li style="font-weight: 400;">Breakfast, lunch, snacks, and drinks provided in the office</li> <li style="font-weight: 400;">Wellbeing benefit and WFH equipment allowance</li> <li style="font-weight: 400;">Annual learning and development allowance to grow your skills and career</li> <li style="font-weight: 400;">Opportunity to work for a globally diverse team</li> <li style="font-weight: 400;">Travel allowance for your commute</li> </ul><div class="content-conclusion"><h4><strong>About Miro</strong></h4> <p class="p1">Miro is a visual workspace for innovation that enables distributed teams of any size to build the next big thing.
