• *The Role**

We're a small, senior engineering team building a B2B SaaS platform at the intersection of data and marketing. The codebase is modern, the work spans the full stack, and there's real room to shape how the team builds — from architecture decisions to engineering standards.

We're looking for a developer who takes ownership seriously: someone who has shipped end-to-end features in a product team, thinks carefully about system design, and is comfortable operating with autonomy. You'll work across backend services, cloud infrastructure, and a Vue.js frontend, with regular exposure to a high-volume data layer.

We work lean — short cycles, close collaboration between product and engineering, and a strong bias toward shipping. If you thrive in a product engineer mindset — where you own problems, not just tasks — this is the right environment.

We're also building AI-powered features into the product, so hands-on experience or genuine curiosity there is a plus.

AI tooling is part of how this team works day-to-day — if you already reach for tools like Cursor or Claude Code, you'll fit right in.

• *What You'll Work On**

Own features across the full stack: backend services, APIs, and frontend interfaces

Build and maintain cloud infrastructure and serverless functions on Azure

Work with a high-volume data layer — consuming external APIs, processing and storing large datasets, and keeping it performant

Contribute to a Vue.js frontend used daily by marketing teams

Participate in architecture decisions, code reviews, and engineering standards (ADRs, documentation, runbooks)

Cover the full development lifecycle: design, implementation, testing, deployment, and support

• *Must-Haves
• 5–7 years of experience in a product-focused SaaS engineering team
• Strong proficiency in TypeScript / JavaScript, both frontend and backend
• Solid experience with PostgreSQL in production — schema design, indexing, query optimization
• Familiarity with containerization (Docker) and microservices patterns
• Comfort working with REST APIs — consuming external ones and designing your own
• Experience deploying to a major cloud provider (we use Azure and GCP)
• Agentic coding workflows — you actively use AI-assisted development tools (Cursor, Claude Code, or equivalent) as part of your daily process, not occasionally
• A degree in computer science or equivalent practical experience
• *Nice-to-Haves
• Experience with Vue.js and/or Azure Functions (serverless)
• Terraform or other IaC tooling
• Python and data pipeline experience (Airflow, Databricks, or similar)
• Familiarity with social platform APIs (Meta Graph API, TikTok, YouTube)
• Hands-on experience integrating ML/AI capabilities in a production system
• *Why Join**
• High-ownership culture — you'll have real say in technical direction, not just tickets to close
• Work directly with a senior tech lead and CTO
• 2 days on-site in Montreal, 3 days remote
