Machine Learning Engineer

About Us

Leonardo.Ai is building one of the world's most advanced generative-media platforms, empowering millions of people to turn ideas into high-quality images and videos in seconds.

Now part of the Canva family, we're scaling our global R&D team to make creativity faster, smarter, and more accessible for everyone.

The Role

We're looking for a Machine Learning Engineer who enjoys working hands-on across model development and ML systems, someone who wants to learn, ship real features, and grow in a high-context, collaborative environment.

You'll join the AI Engineering team inside the Platform Tribe, where we build the training pipelines, inference systems, and model-serving tooling that help teams across Leonardo deliver reliable AI-powered creative experiences at scale.

Your work will support features such as high-fidelity image generation, stylisation workflows, and emerging image-to-video capabilities, helping turn cutting-edge research into creative tools people use every day.

This role offers deep exposure to generative ML, including diffusion and transformer models, while developing your confidence in performance optimisation, GPU environments, and reproducible workflows. You'll work alongside senior ML engineers and research scientists, gaining context and stepping into more ownership as you grow.

If you're excited about generative media and want to sharpen both your modelling and engineering depth, you'll thrive here.

What You'll Do

Model Development and Evaluation

• Collaborate with research scientists to adapt and fine-tune diffusion and transformer-based models.

• Run experiments and evaluate model outputs to improve quality and consistency.

• Contribute to performance improvements such as batching, caching, or quantisation with guidance.

• Help identify bottlenecks and opportunities for generation improvements.

ML Engineering and Systems Development

• Build and maintain training and inference pipelines.

• Work with GPU environments on AWS and Kubernetes.

• Use Docker and internal tools to standardise training, experimentation, and deployment.

• Contribute to shared APIs and model-serving components.

MLOps and Reliability

• Support dataset handling, experiment tracking, and model versioning.

• Extend monitoring dashboards and alerts to maintain system performance.

• Maintain reproducibility across checkpoints, datasets, and experiments.

Cross-Team Collaboration

• Work with product teams to support integration of generative features.

• Share learnings and contribute to a supportive engineering culture.

Skills We Value

• Strong Python engineering skills and familiarity with ML workflows.

• Experience with PyTorch or TensorFlow in project, research, or production settings.

• Understanding of model training or fine-tuning.

• Interest in improving inference performance and efficiency over time.

• Clear, thoughtful communication and collaborative working style.

• Curious and comfortable learning in unfamiliar technical areas.

Nice to Have

• Exposure to diffusion, transformer, or video generation models.

• Familiarity with AWS, Docker, Kubernetes, or GPU orchestration.

• Experience with monitoring or observability tooling.

• Open-source, research, or personal ML project contributions.

• Background in creative-tech, ML tooling, or SaaS environments.

Why You'll Love Working Here

You'll be building technology that directly enables human creativity at scale, not just optimising models in isolation, but shaping how real people express ideas, tell stories, and create art. You'll join a team that values thoughtful engineering, shared context, and steady growth over ego or heroics. There is room to explore, room to ask questions, and room to develop depth in the areas that genuinely interest you. We work with curiosity, we build with care, and we learn from each other as we go.
