Staff Software Engineer Mobile Platform, Rust
Employment Info
JOB DETAILS
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. 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 engineering when AI is a daily part of the workflow.
- Technical knowledge:Native interop: Bindings between system languages and the iOS, Android, and JavaScript runtimes that consume them
- Technical knowledge:Mobile fundamentals: Native iOS and Android depth, not just the JS side of the boundary
- Technical knowledge:Cross-platform architecture: Portable library design across multiple runtimes
- Technical knowledge:Library API design: Making system-language code feel native to the mobile and frontend engineers who consume it
- Technical knowledge:React Native runtime: Enough fluency to know how your libraries get consumed from the JS side
- Technical knowledge:Deep fundamentals: Engineering fundamentals from a CS background, including data structures, complexity, the hard parts
Responsibilities
- 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. 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.
Desired Qualifications
- Live migrations: Production experience evolving a mature mobile product onto a new architecture
- System languages: Rust or C for portable libraries that run across mobile platforms
- Open-source contributions: React Native, Expo, or the cross-platform mobile ecosystem
- Mobile CI/CD: Release trains and over-the-air updates at scale
