Web Developer jobs in Canada

At Harvey, we’re transforming how legal and professional services operate — not incrementally, but end-to-end. By combining frontier agentic AI, an enterprise-grade platform, and deep domain expertise, we’re reshaping how critical knowledge work gets done for decades to come.

This is a rare chance to help build a generational company at a true inflection point. With 1000+ customers in 58+ countries, strong product-market fit, and world-class investor support, we’re scaling fast and defining a new category in real time. The work is ambitious, the bar is high, and the opportunity for growth — personal, professional, and financial — is unmatched.

Our team is sharp, motivated, and deeply committed to the mission. We move fast, operate with intensity, and take real ownership of the problems we tackle — from early thinking to long-term outcomes. We stay close to our customers — from leadership to engineers — and work together to solve real problems with urgency and care. If you thrive in ambiguity, push for excellence, and want to help shape the future of work alongside others who raise the bar, we invite you to build with us.

At Harvey, the future of professional services is being written today — and we’re just getting started.

As a Full Stack Software Engineer at Harvey, you’ll play a pivotal role in constructing the foundation of our product platform while directly building user-facing features for some of the world’s leading law firms and enterprise customers.

We also build enterprise‑grade collaboration product experiences for law firms.

You will design systems that not only serve as critical infrastructure for the rest of the company, but also directly impact how our users engage with Harvey’s AI‑powered legal tools. This role is ideal for engineers who are excited by the opportunity to move between deep platform thinking and hands‑on product iteration.
