Job Description

At Canva, our mission is to empower the world to design. To ensure our generative AI models are truly helpful, we are seeking a talented Research/Machine Learning Engineer to build our next-generation evaluation system by leveraging automatic evaluations.

About the role:

You will engineer sophisticated AI agents that can automatically assess the quality and human alignment of our generative design models. This high-impact role focuses on building the practical systems that make cutting-edge research effective, to provide a rapid feedback loop that guides the future of design generation at Canva, ultimately empowering millions of users to create.

At the moment, this role is focused on:

- Agentic Evaluation Systems: Engineering autonomous AI agents that use Multimodal Large Language Models (MLLMs) to evaluate the quality, relevance, and human alignment of generated designs.

- Inference-Time Alignment: Mastering techniques that improve model outputs without full retraining, but by inference-based methods including prompt engineering, in-context learning and Retrieval-Augmented Generation (RAG).

- Model Benchmarking & Analysis: Building a rigorous framework to systematically benchmark internal and external quality understanding models, delivering clear, data-driven insights on human alignment.

Primary Responsibilities:

- Design, build, and optimize the infrastructure for an "MLLM-as-a-Judge" evaluation system for scalable, automated feedback.

- Implement and experiment with inference-time alignment techniques (Prompt Engineering, RAG, ICL) to directly improve model output quality.

- Establish and manage a comprehensive benchmarking process to compare various foundation models on design-centric tasks.

- Analyze evaluation data to identify model failure modes and provide actionable recommendations to the research team.

- Collaborate with research scientists and ML engineers to integrate the agentic judge system into the model development lifecycle.

- Translate the latest research in LLM evaluation and agentic AI into practical, production-ready engineering solutions.

You’re probably a match if you:

- You have a strong understanding of generative AI models (e.g., Diffusion Models, GANs, Transformers) and their architectures, with practical experience that informs robust evaluation strategies

- Excel at creating data-driven evaluation methodologies, turning user analytics into clear, actionable insights.

- You’ve successfully managed or optimized large-scale distributed model training across hundreds of GPUs

- You have a solid understanding of machine learning, have worked with PyTorch and know how to optimize such codes for speed

- You have disciplined coding practices, and are experienced with code reviews and pull requests.

- You have experience working in cloud environments, ideally AWS

Nice to Have:

- Familiarity with evaluation libraries and frameworks.

- Experience building or working with agentic AI systems or multi-agent coordination.

- Knowledge of data visualization tools to communicate findings effectively.

- A background or interest in human-computer interaction, design principles, or AI ethics.
