We have a preference for candidates located in Montreal and Toronto.

Key Responsibilities

Implement and improve agentic LLM workflows (planner–executor logic, tool calling, structured outputs, reliability).
Build and extend Python backend APIs for email processing, automation, and integrations.
Create and maintain evaluation + tests (small test suites, regression checks, basic metrics) to track quality over time.
Collaborate on product delivery for the Outlook/Gmail experience (not purely research).
Requirements

Currently enrolled in a university program in CS/ML/AI or related field (Master’s preferred).
Strong Python skills and ability to work in an existing codebase (APIs, data handling, debugging).
Familiarity with LLMs/NLP concepts and practical implementation (prompting, parsing, orchestration).
Comfortable working in a fast-moving startup codebase; can ship iteratively with a testing mindset.
Nice to Have

Experience with TypeScript/React or shipping frontend features.
Experience with cloud/devops (AWS), background workers/queues, monitoring.
Experience building evaluation frameworks or working with retrieval/RAG.
Experience with end-to-end UI test automation (e.g., Playwright/Selenium) for web/desktop flows.
