Job Description

About the Group

The Trust & Safety (T&S) Group vision is to empower everyone to feel safe in trusting Canva. To safeguard our community, our T&S engineering teams build technologies to protect user safety (including, but not limited to their account, content, data, and privacy) and to prevent, detect, and mitigate abuse and fraud that could compromise the trust people have in Canva, such as unacceptable content, bots, account takeovers, and other abuse vectors.

Within T&S, the Content Safety Platform team specializes in building safety systems for AI-generated content. As Canva rapidly expands its AI capabilities, our team ensures these powerful creative tools remain safe, trustworthy, and compliant. We develop sophisticated ML-based moderation systems, bias mitigation solutions, IP detection frameworks, and responsible AI safeguards that operate at scale. This team sits at the intersection of cutting-edge AI innovation and critical safety engineering.

About the Role

You'll build the foundational safety infrastructure that powers trust across all of Canva's AI features. We're a platform team—our mission is to provide product teams with the tools, models, and systems they need to safely launch AI-generated content features at scale. Whether it's Magic Media, conversational AI, or future capabilities, product teams rely on our platform to detect harmful content, prevent IP violations, mitigate bias, and ensure compliance across multiple modalities of content.

In this role, you'll own significant ML initiatives that directly enable other teams to move faster while staying safe. You'll build reusable safety models, create scalable evaluation frameworks, and develop infrastructure that serves multiple products. This is a high-impact position where your work becomes the safety foundation for Canva's AI innovation—balancing cutting-edge ML techniques with the operational rigor required to protect millions of users. You'll collaborate closely with AI product teams, Legal, and Product Policy to deliver solutions that meet both product and compliance needs.

What you’ll do (responsibilities):

Own end-to-end delivery of ML-based safety features, from technical design through production rollout and iteration
Build and maintain ML models that safeguard AI-generated content across multiple modalities (images, video, audio, text), detecting harmful content, IP violations, bias, and other safety concerns
Design and implement RAG (Retrieval-Augmented Generation) architectures and other advanced ML systems to enhance detection capabilities
Fine-tune and evaluate LLM-based models for content moderation and prompt filtering, making data-driven decisions about model selection and optimization
Collaborate with Legal, Product Policy, and AI product teams to define requirements, balance safety with user experience, and deliver compliant solutions
Create evaluation frameworks to measure model quality, safety coverage, false positive/negative rates, and policy alignment
Monitor production systems, respond to incidents, and maintain operational excellence through documentation and runbooks

What we're looking for:

You're a machine learning engineer with a proven track record of delivering ML-powered features in production. You bring technical expertise across the ML lifecycle—from data wrangling and model development to evaluation, deployment, and monitoring. You're comfortable operating independently while collaborating with cross-functional teams, and you're motivated by user impact and product outcomes.

Strong bias for action and product-minded approach to engineering
Hands-on engineer who loves working alongside software engineers, writing Python production code (Java/Kotlin backend experience is a plus), and solving complex problems
Experience building and deploying ML systems using modern architectures, including LLMs and RAG
Comfortable influencing roadmap decisions and navigating ambiguous problem spaces
Passionate about the rapidly evolving AI landscape and proactive about experimenting with emerging techniques
