Software Engineer, Full Stack
Gigi, Toronto
The role
We're hiring an AI Builder—a full stack software engineer—to join our engineering team in Toronto and own end-to-end feature development for Gigi, our AI agent.
This is still fundamentally a software engineering role. Much of the work will feel familiar: designing APIs, building interfaces, modelling data, integrating services, writing tests, debugging production issues, and making architectural decisions. The main difference is the product we're building: agentic software where LLMs reason, use tools, and take actions on behalf of customers.
You do not need to be an AI researcher or have years of professional LLM experience. Strong full stack engineers who are excited to learn how agentic systems work should apply. You'll use tools such as Codex, Claude Code, and Cursor as a core part of how you work, while building across agent logic, backend services, data, and the customer-facing product.
This is the 12th role at Gigi. As an early employee, you will have a meaningful role in shaping our product, engineering culture, and company.
