Canva Jobs (NOW HIRING)

Join the team redefining how the world experiences design.

Hey, g'day, mabuhay, kia ora,, hallo, vitejte!

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 head office is in Sydney, Australia, but San Francisco is now home to our US operations.  The role is listed as hybrid, meaning we are incredibly flexible and empower you to work where you prefer - whether that's at home or at the office. 

About the role

Canva's generative models are judged by millions of people who will never read a benchmark. They just know whether the design looks right. Turning that judgement into something measurable is the hardest problem in our research stack, and it gates everything else. If we cannot measure design quality reliably, we cannot train against it, we cannot tell a real improvement from noise, and we cannot decide what ships.

We are looking for a Principal Research Scientist who defines what evaluation needs to become as the space gets harder, rather than running the playbook we already have. You will own how Canva evaluates generative quality across the whole of Canva Research, including problems we have not framed yet: new modalities, evaluation that reflects real differences between content types, user segments and markets, and a much tighter link between what our metrics say and what users and the business actually experience.

This is a Canva-wide craft leadership role, setting direction across our research groups in Australia, Europe, the US and China. You will be the person others come to when the numbers and the eyes disagree.

What you'll own

The evaluation strategy for Canva Research. Define what great evaluation looks like across design, image, video, audio and agentic workflows, and set the long-term direction for how Canva measures generative quality as the space evolves. You will shape the principles teams use to trade off evaluation compute, human data spend and signal fidelity, and you will defend them.

The science of measurement itself. Auto-raters and MLLM judges are only as good as their correlation with the thing they proxy for. You will treat that correlation as a research problem: validating metrics against human preference and downstream product outcomes, quantifying judge bias, and catching benchmark saturation and contamination before they quietly stop telling us anything.

The link between evaluation and what actually matters. Evaluation should reflect user experience and product impact, not just perform well in isolation. You own closing that gap, including the fact that a good evaluator is not automatically a good reward model for RL. That extends to the full experience rather than the artefact alone, editability included.

One standard across every region. Our teams in London, Vienna, San Francisco, Sydney and China all need to know they are measuring the same thing. You will build the shared evaluation layer that makes results comparable, and you will spot the collaboration opportunities nobody has been chartered to own yet. Taking that initiative is a core expectation of this role, not a bonus.

Focus areas

Human preference at scale. Rubric design, rater guidelines, inter-rater reliability, and calibration across markets and cultural contexts. Aesthetic judgement is not universal, and our evaluation systems need to hold that honestly rather than average it away.

Learned quality models and reward signals. Reward modelling and preference learning that feed post-training (RLHF, RLAIF) and inference-time selection, and being explicit about where a good judge does not translate into a good reward model.

Vision-Language Models for quality understanding. Novel architectures and training approaches for models that understand what makes a design effective, not just well-formed. These become the reward signal and feedback loop for our design generation models, so their failure modes are our failure modes.

Agentic and automated evaluation. MLLM-as-a-judge systems, model-based grading, and the infrastructure to run hundreds of evaluations against live training checkpoints without the results becoming noise.

Multimodal and segment-specific evaluation. Extending rigour into photo AI and video as they mature and start moving faster than traditional user research and marketing testing can cover, with evaluation that can be sliced meaningfully by doc type, user group and locale.

Evaluation in production. Offline evaluation suites and online monitoring, with regression detection that makes a quality drop impossible to miss before it reaches users.

External credibility. Benchmarking Canva's models against the frontier, and building evaluation work others in the industry look to. Publication and public reporting where it serves the mission.

Primary responsibilities

• Establish the evaluation gates that inform launch decisions, and be accountable for the judgement calls when the signal is ambiguous

• Diagnose anomalous evaluation results during production training runs, separate model regressions from infrastructure artefacts, and communicate the answer clearly and quickly

• Partner with Design Generation, Foundation Models and Agents teams so evaluation shapes their training and inference, rather than reporting on it after the fact

• Work directly with designers, creators and product teams to turn subjective creative judgement into measurable criteria

• Mentor senior research scientists and engineers, and raise the bar for evaluation craft across the group

• Represent Canva's evaluation vision and practice to senior leadership and, where valuable, to the broader industry community

You're probably a match if you have

• A track record of defining evaluation frameworks and standards from the ground up rather than operating inside someone else's, ideally at an organisation pushing the frontier of GenAI evaluation, and measurement systems that changed how a team made decisions rather than papers about metrics

• Experience linking evaluation metrics to downstream business or user outcomes, and diagnosing why they diverge

• Experience turning subjective human judgement into reliable, objective evaluation signal through rubric design, human data pipelines and model training

• Strong grounding in multimodal generative models (diffusion, transformers, VLMs and MLLMs) and their architectures, deep enough to know where evaluation will break

• Experience with reward modelling, preference learning, or alignment methods involving human feedback

• Experience setting technical direction across multiple teams or a wide specialty area in a globally distributed organisation, with the instinct to find the gap nobody owns and close it without waiting for a mandate

Nice to have

• Research background in human perception, psychophysics, aesthetics or HCI

• Experience evaluating for harm, bias and safety alongside quality

• Publication record in evaluation, alignment or generative modelling

• Background or genuine interest in visual arts and graphic design
