Staff Software Engineer - Mobile Platform

Requirements

• Mobile depth: Built production mobile software on iOS and Android, not just one. You understand the platforms deeply enough to know where they diverge, where they don't, and how to write libraries that feel native on both.
• System languages: Shipped production code in Rust, C++, or another system language. The portable libraries are the centre of gravity for this role, and they live in this layer.
• Staff altitude: You've been operating where both the problem and the solution are unknown. You walk into ambiguous work saying "this is the shape of the problem, this is what I think we should do, here's where we'll experiment."
• Cross-platform fluency: You understand what it takes to write code that runs well across multiple runtimes. You've thought hard about ABI boundaries, memory safety across language barriers, and the ergonomics of foreign function interfaces.
• Technical communication: You write design docs that other engineers act on. The libraries you build need to be understood by the engineers consuming them, and clear writing is how that happens.
• AI fluency: Used agents in real work. Have a view on what changes for mobile and systems-level eng

Join the team redefining how the world experiences design. Hey, g'day, kia ora, 你好, hallo, vítejte! Thanks for stopping by. We know job hunting can be a little time consuming and you're probably keen to find out what's on offer, so we'll get straight to the point. Where and how you can work Collingwood is home to our Melbourne campus - a vibrant, creative hub for connection and impactful work. While Sydney is home to our HQ, Melbourne brings its own unique vibe, with local artwork, lush greenery, and thoughtfully designed spaces to help you collaborate, focus, and feel part of a welcoming community. This role is based in Melbourne, and we're looking for someone who calls it home. Our hybrid way of working gives you the flexibility to work remotely, and to come together on campus for meaningful in-person collaboration and connection when it matters most. What you'd be doing in this role Mobile Platform owns how Canva runs on iOS and Android, and the portable libraries layer is one of the most technically interesting pieces of the mobile bet. Every product team at Canva builds on top of what this group ships. Write the foundational libraries once, in a performant system language, and run them everywhere. Rust and C are on the table. The interface, the safety model, and the ergonomics for engineers consuming them across every runtime are the open problems. The strategic bet is a hybrid stack with React Native at its core, supported by a set of portable libraries that run across iOS, Android, and web from a single codebase. This role sits at the heart of the portable libraries work. Hundreds of millions of users open Canva on a phone or tablet, and the libraries you build will run underneath every one of them. There's a second reason this work matters now. This is where deep mobile expertise meets systems programming. Not many engineers operate at that intersection. The ones who do shape how products like Canva get built for the next decade. .At the moment, this role is focused on: Owning the portable libraries problem space: Define and build the libraries that run across iOS, Android, and web. The interface, the safety model, and the ergonomics for consumers in every runtime are yours to shape. Working in system languages: Rust and C++ are the tools for the foundational layer. Build production-grade libraries that need to be fast, safe, and reliable across every device Canva ships to. Joining a technical leadership group: This isn't a lone-Staff seat. You'll work alongside other Staff engineers shaping the mobile platform's technical direction, with room to flex into the problems where your strengths land hardest. Leading with code, not whiteboards: Canva doesn't have an architecture function - Staff engineers stay hands-on. This role is heavily hands-on. The work is the work. Communicating across the stack: The libraries you build will be consumed by frontend engineers who don't write Rust or C++. Strong technical communication isn't a nice-to-have for this role. It's how the work lands. Sparring with strong peers: The technical debate is hard, fast, and substantive. Bring strong opinions, change your mind when better evidence shows up. The bar is high. Influential Individual Contributor: No direct reports. But how you operate sets the standard others reach for. What success looks like. The portable libraries ship to production and run reliably across iOS, Android, and web. The interface feels native to the engineers consuming it from every runtime. The patterns set by this role become the foundation that other mobile work at Canva builds on. You're probably a match We'd love to hear from you if you fit one or more of these. You don't need to meet all of them, but the more the better and if you join the team, we're invested in helping you grow.
