Artificial Intelligence Engineer

Salary CAD $200,000 per year (negotiable)

Job type Full‑time, Permanent

DATAHEAD is exclusively representing a senior AI Engineer position at a global supply chain tech firm trusted by Fortune 50 brands.

This is a high‑ownership, senior engineering role focused on building production‑grade AI systems - not maintaining someone else’s pipeline. You will be architecting and shipping LLM systems that directly impact how global logistics operates, reporting into the Head of R&D with real autonomy from day one.

If you thrive in environments where decisions matter, ambiguity is normal, and ownership is genuine - read on.

• Design and build production‑grade LLM systems — RAG pipelines, agents, and APIs
• Own end‑to‑end delivery of critical AI features
• Define and implement evaluation frameworks (golden sets, regression testing)
• Architect systems for cost, latency, and reliability at scale
• Drive architectural decisions with long‑term implications
• Provide technical guidance to engineers on adjacent teams

• Proven experience shipping LLM‑powered features to production — this is a hard requirement
• Deep expertise in RAG systems: advanced retrieval, chunking strategy, and evaluation
• Hands‑on prompt engineering at API level, not just wrapper libraries
• Experience with agent architectures:
  ReAct, tool calling, planning loops
• Ability to operate independently in fast‑moving, ambiguous environments
• Bachelor’s or Master’s degree in Computer Science or a related field

• Fine‑tuning experience — LoRA, SFT, DPO
• Observability tooling — Langfuse, Lang Smith
• Public work (Git Hub, writing, conference talks) that demonstrates genuine depth
• Prior experience on early‑stage or high‑ownership teams

Month 1 — Get deep into the existing architecture. Contribute to live systems, not just onboarding tasks. Identify gaps and risks early.

Month 2 — Own and deliver a critical feature or system component end‑to‑end. Improve at least one existing system across performance, evals, or architecture.

Month 3 — Trusted senior engineer on the team. Driving architectural decisions. Delivering measurable impact on reliability, quality, or efficiency. Operating with minimal oversight.

• Real ownership — not a supporting role in a large org
• Small, high‑calibre team with deep operational domain expertise
• Systems that directly power real‑world global commerce
• Competitive salary with room to negotiate
• Hybrid working from Toronto
• Full benefits, learning budget, flexible leave, and ESOP where applicable
