Job Description

We’re hiring a Senior AI Platform Engineer (Knowledge & Data) to build and own the LLM knowledge and retrieval layer that powers AI features across MaintainX. You’ll build backend services and pipelines that transform raw documents, APIs, and semi-structured data into production-grade knowledge systems, with clear patterns for ingestion, retrieval, ranking, and caching. Your work enables product teams to ship AI features quickly without re-solving knowledge preparation, retrieval quality, or reliability problems.

Job Responsibility

  • Build scalable backend services and internal APIs for the AI platform
  • Integrate LLMs and retrieval into reliable, production-ready workflows
  • Build knowledge ingestion pipelines for LLMs (documents, APIs, semi-structured data)
  • Design chunking and embedding approaches together with vector DB data models and indexing strategies
  • Implement retrieval pipelines (semantic, keyword, hybrid) and caching
  • Contribute to shared infrastructure: CI/CD, observability, deployments

Requirements

  • 5+ years of experience in Python backend engineering and systems design experience
  • Experience shipping AI-powered or LLM-integrated backend systems
  • Experience with vector DBs (Qdrant/Pinecone/Chroma/etc.)
  • Understanding of embeddings, chunking, and retrieval strategies
  • Experience building search or retrieval systems over unstructured data
  • Comfort working across multiple layers (services, data, infra, AI tooling)

What we offer

  • Competitive salary and meaningful equity opportunities
  • Healthcare, dental, and vision coverage
  • 401(k) / RRSP enrollment program
  • Take what you need PTO
