Software Engineer, AI Platform

Everflow • Montreal, QC

11h • CA$100,000 - CA$110,000 • Hybrid

About The Position

Everflow handles massive scale in the ad-tech space. We are looking for an AI Engineer who views LLMs as just one component in a complex, high-concurrency distributed system. You will lead the charge in evolving our platform from "data-rich" to "intelligence-driven." We are a GCP shop, but we don't just follow the documentation—we build ahead of it. You will be responsible for architecting how Gemini and the evolving Vertex AI suite integrate into our real-time attribution and analytics engine.

Requirements

• You understand the fundamentals of distributed systems, concurrency, and data integrity.
• Strong experience with the Google Cloud ecosystem (BigQuery, Pub/Sub, GKE) and Vertex AI.
• High proficiency in French and English is required.
• Ability to work from our Montreal office at least two days per week to foster high-bandwidth collaboration with our local engineering hub.
• You understand that in our world, latency is the enemy and accuracy is the product.

Responsibilities

• Design the "connective tissue" between our massive BigQuery datasets and agentic AI workflows.
• Evaluate and implement emerging GCP technologies (including those announced at Cloud Next) to keep Everflow at the cutting edge of Mar-Tech.
• Ensure that AI-driven features—like automated fraud detection or partner insights—are deterministic, cost-controlled, and sub-second.
• Design modular AI services that allow us to swap models or orchestration frameworks (e.g., moving from manual RAG to autonomous Vertex Agents) as the GCP ecosystem evolves.
• Build the secure API layers that allow Gemini to "act" on behalf of our users within the Everflow ecosystem.
• Engineer the middleware that handles model routing, semantic caching, and token-budgeting to maintain our margins.
• Work alongside our Data Scientists to move models from experimental notebooks to production-grade Cloud Run/GKE deployments.

Benefits

• Base Salary: $100,000 - $110,000 CAD
• Bonus Potential
• Employer Medical and Vision Insurance Group Plans
• Unlimited PTO and paid holidays
• Paid parental leave for putting your family first
• Startup-like environment, without the constant rush to raise the next round of funding
• A very collaborative team and culture
• Education, gym, and equipment stipend
