AI Data Systems
For roles like AI Data Engineer, Machine Learning Data Engineer, Retrieval Engineer
Build reliable data, feature, embedding, retrieval, evaluation, and observability pipelines for AI systems.
Is this route for you?
Do you want to make the data behind training, retrieval, evaluation, and production behavior trustworthy?
- You care about lineage, repeatability, and data quality more than demos.
- You enjoy tracing model behavior back to data and retrieval decisions.
- You want to connect data systems with measurable AI outcomes.
What you'll be able to do: Build on shared foundations to create traceable AI data systems that transform source data into measurable model and retrieval inputs.
Start with
- Complete the shared software engineering and AI foundations, or demonstrate equivalent working knowledge.
- Be comfortable with tabular data, features, train and test splits, and basic evaluation.
- Be able to inspect files, schemas, and pipeline output from code.

Portfolio project: Traceable AI Data Pipeline
Build a reproducible data and retrieval path whose inputs, transformations, quality checks, and downstream effects can be inspected.
- A reproducible ingestion and transformation pipeline
- Leakage, schema, and data quality checks
- Embedding and retrieval evaluation results
- Observability for data-dependent failures
- A provenance and rollback note
You're ready when you can
- Explain lineage from raw data to model or retrieval input.
- Prevent leakage and verify feature transformations.
- Measure retrieval quality separately from generation quality.
- Identify a data, embedding, retrieval, or model cause from evidence.
- Reproduce a pipeline result and document how to roll it back.
What this route covers, honestly
- Data and feature pipelines
- Embeddings and retrieval
- RAG evaluation
- AI observability
- Lineage and schema evolution
- Pipeline orchestration and backfills
- Data governance
- Enterprise warehouse or lake ownership
- Compliance authority
- Live data platform on-call experience
AI Data Systems career route certificate
Pass all 11 lesson checks on this route (0 done), then the 20-question route exam drawn from these lessons. The certificate lists every topic you covered and carries an ID anyone can verify.
Completing this route shows that you can build and evaluate a traceable AI data pipeline. It does not guarantee a role or establish experience operating an enterprise data platform. This is a specialist overlay after shared foundations. It samples training, feature, and retrieval data work, but does not claim mastery of every warehouse, lake, streaming, or governance platform. The estimate covers lesson time only. Portfolio work and practice take additional time.
