Principal AI Engineer, Distributed Systems & Intelligent Platforms

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Principal AI Engineer, Distributed Systems & Intelligent Platforms based in Canada.

This is a senior technical role focused on building and scaling intelligent, AI-native platforms operating at production-grade complexity. You will work on live, high-traffic distributed systems where reliability, performance, and architectural clarity are critical. The role blends AI engineering with distributed systems design, requiring deep expertise in backend development, cloud infrastructure, and event-driven architectures. You will contribute to building intelligent workflows, agentic systems, and scalable APIs that power next-generation learning and development platforms. The environment is highly collaborative, engineering-driven, and focused on solving complex real-world problems at scale. It is ideal for a hands-on principal-level engineer who thrives in deep technical ownership and production-critical systems.

Accountabilities

In this role, you will be responsible for designing, building, and scaling distributed AI-driven systems and backend platforms that support high-traffic, production-grade applications.

• Design, build, and maintain backend services using Python and Node.js within cloud-native architectures
• Develop and evolve APIs and integration layers connecting frontend applications with distributed backend systems
• Architect and implement event-driven systems, including workflows, state machines, and asynchronous processing pipelines
• Contribute to advanced NoSQL data modeling, including scalable schema design, transactional patterns, and performance optimization
• Build and support AI-driven systems including LLM workflows, RAG pipelines, embeddings, and multi-agent orchestration
• Own production systems, including monitoring, debugging, observability, and continuous reliability improvements
• Collaborate with cross-functional engineering teams to deliver end-to-end features and improve system architecture
• Participate in code reviews, technical design discussions, and contribute to engineering best practices across the team
  
  

Requirements

The ideal candidate brings deep experience in distributed systems, backend engineering, and production AI systems, with strong ownership of scalable architecture.

• 6+ years of professional software engineering experience building production-grade systems
• Strong expertise in Python and Node.js development
