Senior, AI & Agentic Engineer

Location: Montreal

Artefact is a next-generation data and AI consulting firm dedicated to accelerating the adoption of data and AI to create measurable business impact across the full enterprise value chain.

We sit at the intersection of consulting, data science, AI technologies, data engineering, and digital transformation. We do not just advise — we build, implement, and deliver results our clients can measure. Our teams bring together consultants, data scientists, data engineers, AI engineers, analysts, and digital experts to solve complex business challenges with pragmatic, production-ready solutions.

As Artefact continues to grow globally, we are building a team of entrepreneurial data and AI talent who can help clients move beyond experimentation and into scalable, governed, value-generating AI adoption.

The Role
Artefact is looking for a Senior AI & Agentic Engineer: a full-stack engineer who takes AI features from idea to production.

You will design and build the interfaces, services, and agentic systems at the heart of our client work, such as conversational applications over enterprise data, multi-step agents that automate business workflows, and the retrieval and data pipelines that support them. You will own your components end to end: the React front end, the Python or Node service behind it, the RAG pipeline feeding it, and the evaluations proving it works.

This role combines breadth and depth: the ability to take a feature from front end to cloud deployment, together with strong expertise in at least one major AI platform — Google (Gemini), Anthropic (Claude), or OpenAI.

You will work with direct client exposure, and you will support the professional development of the junior engineers around you.

What You'll Do
Build Full-Stack AI Applications, End to End
You will build AI products across the entire stack, from interface to infrastructure.

Develop user-facing interfaces in Type Script/React and the backend services and APIs behind them in Python or Node.

Implement agentic behavior: orchestration, tool and function calling, memory, and guardrails.

Build retrieval-augmented generation (RAG) pipelines: ingestion, chunking, embeddings, vector and hybrid search.

Connect AI systems to enterprise data and applications via APIs, semantic layers, and protocols such as MCP.

Make AI Systems Production-Grade
Our standard is production quality: systems that are reliable, monitored, and maintainable.

Write evaluation suites and regression tests for LLM-powered features, and monitor cost, latency, and quality in production.

Apply solid engineering practice: version control, code review, automated testing, CI/CD, and observability.

Deploy on cloud infrastructure (GCP, Azure, or AWS) using containers, serverless, and infrastructure-as-code.

Build and maintain the data pipelines that feed AI systems, across warehouses, lake houses, and vector stores.

Work AI-Natively and Client-Facing
Our engineers work AI-natively and represent Artefact directly with clients.

Use agentic coding tools (Claude Code, Gemini CLI, Codex, Cursor) daily, with good judgment about verification and review.

Communicate progress, trade-offs, and blockers clearly to clients and project leads.

Support pre-sales when needed: scope solutions, build demos, and estimate effort with our partnership and consulting teams.

Mentor junior engineers and contribute to internal accelerators, reusable components, and engineering standards.

What We're Looking For
Required Experience

3–5 years of experience in software engineering or data engineering, with extensive hands-on use of AI tools and LLM-based development over the past year (professional projects, internal initiatives, or substantial personal builds).

Professional English proficiency mandatory. You will work daily…
