About the role

AI Platform Engineer at LANDR designing collaborative ecosystems of AI agents for music creators. Responsibilities include data architecture, pipeline optimization, and product collaboration in a hybrid work setting.

Responsibilities

Design and implement interaction logic for a multi-agent ecosystem where distinct agents collaborate to create a single, verifiable source of truth
Design and build pipelines that allow AI systems to query user catalogs, publication metadata, mastering history, engagement statistics, and platform behavior instantly
Manage access to real-time data at large scale
Build clean, fast interfaces that allow our AI orchestrator to access user context without touching production databases directly
Balance the use of costly LLM calls with deterministic logic to optimize cost and latency at scale
Work with the AI Product Manager and full‑stack developers to translate complex backend logic into a conversational, seamless user experience
Implement strict validation layers to prevent hallucinations around critical compliance rules and external policies, and ensure user data is handled securely

Proven experience building production-grade agentive systems (LangChain, AutoGPT, or custom orchestrators)
Hands-on experience with contextual LLM systems – you’ve worked on RAG systems, context windows, or AI products that require custom access to data
Proficiency in Python, SQL, and ETL patterns for structuring data for AI retrieval
Experience with vector databases and semantic search – you understand integrations, similarity search, and how to structure data for AI retrieval (Pinecone, Weaviate, Qdrant, or similar)
Experience implementing “LLM-as-a-judge” workflows or human-in-the-loop processes to measure accuracy
Fundamental knowledge of machine learning (ML) – you understand supervised and unsupervised learning and can evaluate trade-offs when selecting models

Health insurance coverage, with access to virtual doctors via Maple and an employee assistance program (via Homewood)
Access to our RRSP program, including an employer contribution of up to 2% of your annual salary
Frequent office and social events (catered lunches on Mondays, bagel Tuesdays, 5@7 socials, etc.)
