Why Harvey

At Harvey, we’re transforming how legal and professional services operate. 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 1500+ customers in 60+ 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 moves fast, takes ownership, and is deeply committed to the mission — operating with intensity, staying close to our customers, and pushing each other for excellence. We live by three values: Decisiveness, Simplicity, and Job's Not Finished. We act quickly on clear judgment over perfect information, we believe simplicity is what scales, and we're never satisfied with where we are. If you want to do the best work of your career alongside people who share that drive, we'd love to build with you.

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

Role Overview

As a Staff Full Stack Software Engineer at Harvey, you’ll play a pivotal role in shaping the foundation of our product platform while directly building user-facing features for some of the world’s leading law firms and enterprise customers. This team owns and operates the platform layer that enables secure, reliable, and flexible experiences for our customers including notifications, permissions and feature flag infrastructure. We also build enterprise-grade collaboration product experiences for law firms.

You will design and own 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.

This role is based in Toronto, Canada. We use a hybrid, 3+ days-per week in-person work model and offer relocation assistance to new employees.

What You'll Do

Design and build foundational infrastructure including authentication, permissions, feature flagging, notifications, and document management integrations
Build and evolve Harvey’s internal product platform, accelerating development across multiple product lines and engineering teams
Lead development of enterprise-facing features, such as secure multi-party collaboration, cross-organization workflows, and robust admin controls
Maintain high standards for security, privacy, and system reliability, particularly in handling sensitive legal data
Collaborate cross-functionally with product, AI, design, and GTM teams to deliver delightful, enterprise-ready experiences

What You Have

5+ YoE (post-BS/MS) in a product focused full-stack software engineering role.
Experience with React, Typescript, CSS (we use TailwindCSS), Python, or related.
Track record of building fast-growing SaaS products by leveraging PWA technologies.
Track record of shipping highly intuitive products, strong attention to detail.
Experience building backend platforms that can support multiple product lines.
Strong programming skills and general Computer Science knowledge.

What We Offer

Be part of building something special as a founding member of our Toronto team
Structured hybrid working arrangement: 3 days in our Toronto office, 2 days working from home

We are an AI company and we use AI to improve all of our processes, including in the recruitment process. Whilst we do use AI to help improve efficiency in our recruitment process, we do not rely on AI to make any automated decisions and ensure that a human reviews AI output.
