Senior Backend Engineer (Java) AI Media Transforms (mfx)

Join the team redefining how the world experiences design.

Servus hey gday mabuhay kia ora 你好 hallo vítejte!

Thanks for stopping by. We know job hunting can be a little time consuming and youre probably keen to find out whats on offer so well get straight to the point.

Where and how you can work

Our flagship campus is in Sydney Australia but Austria is home to part of our European operations. And you have choice in where and how you work we trust our Canvanauts to choose the balance that empowers them and their team to achieve their goals.

Fun fact a big part of our Austrian operations is developing the AI product within Canva to help reimagine how artificial intelligence can be used in design. Pretty cool ha!

What youd be doing in this role

As Canva scales change continues to be part of our DNA. But we like to think thats all part of the fun. So this will give you the flavour of the type of things youll be working on when you start but this will likely evolve.

At the moment this role is focused on:

• Build and operate the AI editing serving stack. Own the backend services that run inpainting outpainting upscaling background removal and the next generation of editing capabilities from API design and pipeline implementation through the async worker / ML-worker handoff and GPU-backed inference to production monitoring.

• Productionise model work from research. Partner with CORE and Photo AI to take research-grade editing models and turn them into well-tested observable cost-aware capabilities. Write the pipelines evals and rollout patterns that make this repeatable.

• Design the shared building blocks. Build the reusable libraries (upscaler outpainting depth estimation segmentation BG removal) that other Canva teams compose into their own AI features so we solve each problem once.

• Drive inference performance and cost. Identify bottlenecks across the editing stack GPU utilisation pre/post-processing around GPU steps batching streaming request routing and ship improvements that move both latency and $/request.

• Partner across teams. Work closely with Photo AI on product requirements CORE on model research Inference on GPU serving and consumer teams (Canva AI Design Agent graphics surfaces) on landing editing capabilities on IGS.

• Raise the bar on the team. Set technical direction together with the teams ML tech lead and act as the backend tech lead for the team contribute to architecture and design reviews mentor MLEs and BEs on backend craft and participate in the on-call rotation.

Youre probably a match if

• You have significant commercial experience designing building and operating high-performance high-throughput backend systems in production.

• You have high proficiency in Java or a similar JVM language (Kotlin Scala) with a solid grasp of the surrounding ecosystem.

• You have strong computer science fundamentals concurrency distributed systems performance engineering and the design patterns that come with running services at scale.

• Youre comfortable working alongside ML engineers and researchers. You dont need to train models but you should be able to read PyTorch reason about GPU memory and inference latency and have opinions about how models should be served.

• You have a track record of leading technical initiatives end-to-end driving architecture decisions partnering with senior engineers and raising the technical bar on a team.

• You communicate clearly in writing and verbally with the ability to make complex technical trade-offs understandable to product ML and infra audiences alike.

About the team

The Transforms team sits inside AI Media in the Generative Experience group. The teams mission is world-class AI editing as a platform capability the generative side of editing existing media rather than generating from scratch. We partner closely with the Photo AI group (who own product and model selection) CORE (model research) and Inference (GPU serving) and we land everything on a shared platform so other Canva teams can reuse what we build. Were a small senior team based in Vienna recently formed from Canvas Photo AI engineers.
