AI / ML Engineer (Developer Tools & Agents)

AI / ML Engineer (Developer Tools & Agents)

Toronto, Canada | Up to $280k CAD

Join a highly technical team shaping how AI agents interact with the web by building the tools, frameworks, and developer experiences that power the next generation of browser-based AI systems. This is a role for engineers who care as much about developer experience and usability as they do about system design and performance.

What you’ll be working on

• Building developer tools that let engineers run and orchestrate browser agents on top of a API
• Running experiments to understand which models, prompts, and agent harnesses actually work in production-like conditions
• Designing eval sets to benchmark agent performance against realistic, messy web scenarios
• Creating open-source demos that showcase what’s possible with AI agents and browser automation
• Working directly with customers to help them integrate and deploy custom agent workflows
• Writing technical deep-dives sharing insights from real-world debugging and system behaviour

What we’re looking for

• 4+ years of experience writing high-quality production code
• Strong “AI-native” mindset and active use of AI tools and agents in daily workflows
• Experience shipping full-stack features end-to-end (frontend, backend, and systems integration)
• Interest in developer tooling, APIs, and developer experience design
• Strong communication skills, with ability to write clear technical content
• Strong product intuition and ability to turn ambiguous problems into usable tools
• Comfortable working in highly autonomous, fast-moving environments

What’s in it for you

• Define how developers build with AI agents on the web from the ground up
• Work across infrastructure, product, and applied AI in a single role
• Ship open-source tools and demos used by a growing developer community
• Influence real product direction through experiments and developer feedback loops
• Work closely with early customers and see your work used in production quickly
• High ownership, low process, and direct impact on a fast-growing platform
