Senior AI Engineer

Job Title: Senior AI Engineer

Job Location: Toronto,Ontario-3days per week in office Required-Hybrid

Job Type:Long Term Contract

Mandatory Skills:

• JVM Engineering (Java/Kotlin)

• Knowledge Graphs (Neo4j, Cypher, GraphRAG)

• MCP (Model Context Protocol)

• Production Platform Engineering (CI/CD, Docker, Kubernetes, Observability)

• Document Generation & Rendering (Apache POI, PDFBox, pptxgenjs, Office Open XML, Word/PPT/PDF generation, template management).

Required Qualifications

These apply to everyone we will consider.

• 6-10 years building production software, including recent hands-on delivery of AI or large-language-model systems beyond prototypes.

• Strong JVM engineering (Java; Kotlin or Scala a plus) with solid practices: Git workflows, code review, automated testing, structured logging, and clean design.

• Hands-on experience with modern GenAI patterns: prompt engineering, structured or JSON outputs, tool and function calling, retrieval-augmented generation, and agentic workflows.

• Experience designing and querying a graph or document database (Neo4j and Cypher, or MongoDB Atlas) and using vector search and embeddings for semantic retrieval.

• A track record of owning your own delivery path: you have taken something you built through a pipeline into production and operated it, rather than handing it over.

• Practical experience evaluating non-deterministic systems: test design, quality scoring, regression suites, and translating evaluation into business-ready acceptance criteria.

• Demonstrated ability to design and explain solution architecture (data flow, runtime flow, interfaces, failure modes, and controls) and to explain model behaviour, limitations, and trade-offs in plain language.

And real strength in one of these two adjacent areas

• Platform and reliability: a major cloud (Azure preferred), containerized deployment with Docker and Kubernetes, CI/CD, observability, and automated quality gates on a service you ran in production.

• Deliverable generation and rendering: producing Word, PowerPoint, PDF, or Excel output programmatically with libraries such as Apache POI, PDFBox, or pptxgenjs, making that output deterministic and testable, and moving comfortably between a JVM service and a Node.js rendering toolchain.

Preferred Qualifications

• Experience with the Model Context Protocol (MCP), building tool or resource servers and clients, and with agent-to-agent (A2A) interoperability.

• Experience integrating with low-code agent platforms such as Microsoft Copilot Studio.

• Experience with event-sourced or workflow frameworks (for example, the Akka SDK, Temporal, or similar) for long-running, restart-safe processes.

• Experience with cloud AI services (for example, Azure OpenAI or Azure AI, or equivalent), GraphRAG, and document-intelligence or OCR pipelines.

• Experience building conformance, golden-output, or contract-test harnesses.

• Comfort across languages: Python and Bash for tooling, and the ability to read a Node.js codebase as readily as a JVM one.

• Familiarity with Office Open XML internals, or with rendering diagrams and charts programmatically (SVG, layout engines such as elkjs, or headless rendering).

• Experience implementing GenAI guardrails and delivering under formal AI or model-risk governance.
