Join the team redefining how the world experiences design.
Hey, g'day, mabuhay, 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
Our flagship campus is in Sydney. We also have a campus in Melbourne and co-working spaces in Brisbane, Perth and Adelaide. But 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.

What You'd Be Doing In This Role
As Canva scales, change continues to be part of our DNA. But we like to think that's all part of the fun. So this will give you the flavour of the type of things you'll be working on when you start, but this will likely evolve.

At The Moment, This Role Is Focused On

• Designing and architecting Inference platform components that are composable and deliver value for a variety of use cases.
• Building and scaling Canva's Inference platform components to handle rapid growth.
• Working closely with other teams to understand how we can improve our existing services and platforms, or introduce new ones, in order to optimise their efficiency.
• Providing tooling and libraries for the MLEs to use LLM providers reliably and easily.
• Managing LLM provider platforms.
• Implementing changes that uplift ML Services to be on par with Backend Services.
• Working towards "platformizing" new capabilities or enhancing existing ones, such as model observability.
• Continuing to explore opportunities for our platform teams to better leverage each other in order to optimise for delivery of both product and R&D teams.

You're probably a match if

• You have a deep understanding of machine learning inference, including model serving, optimization, and scaling challenges.
• You have experience in building high-performance, large-scale ML systems.
• You possess deep expertise in Python and Java development, with experience in designing and building ML components as microservices being a plus.
• You have a deep understanding of ML Framework internals and inference frameworks such as vLLM and SGLang.
• You are passionate about engineering excellence, systems architecture, and meeting non-functional requirements.
• You understand Computer Science/Engineering fundamentals and first principles, covering system design, data structures, architecture, and design patterns.
• You have excellent collaboration, communication, and stakeholder management skills.

It would be preferable if

• You are familiar with LLM inference optimisation techniques such as prefill-decode disaggregation and KV cache management.
• You have exposure to the AWS ecosystem, including EKS and ECR.
