The five stages

Design and run the data pipelines that power analytics and ML systems.

  1. Stage 1Months 0–2

    Foundations

    Data engineering is plumbing first, analytics second. Get SQL, Python and one warehouse engine into muscle memory before anything else.

    • SQL fluency: window functions, CTEs, query plans, indexes
    • Python daily with Pandas + Polars; one ETL script a week
    • Pick one warehouse (Snowflake / BigQuery / Redshift) and master its SQL dialect
    Salary range₹7L – ₹15L
  2. Stage 2Months 2–5

    First job-ready skills

    Pipelines + tests + lineage. Hiring panels look for whether you treat pipelines as software (PRs, tests, CI) — not as one-off scripts.

    • Airflow / Dagster / Prefect — three DAGs in production-shaped repos
    • dbt models with tests + docs + lineage on a real warehouse
    • Kafka or Kinesis basics: produce, consume, partition reasoning
    Salary range₹7L – ₹15L
  3. Stage 3Months 5–10

    Real projects

    Build a portfolio that proves you can hold a 24/7 data layer up. SLA, alerting and data quality are senior expectations — start practising them now.

    • One end-to-end pipeline with SLAs, alerting (PagerDuty/Opsgenie) + runbook
    • Implement a data-quality framework (Great Expectations / Soda / Monte Carlo-lite)
    • Ship one CDC (Debezium / Fivetran-style) pipeline from OLTP to warehouse
    Salary range₹15L – ₹19L
  4. Stage 4Year 2–3

    Specialisation

    Specialise. Streaming, lakehouse and reverse-ETL each pay differently — pick what your target employer cluster (GCC vs product) actually runs.

    • Choose: Streaming (Flink / Spark Streaming), Lakehouse (Iceberg / Delta), Real-time analytics
    • Lead one cost-optimisation review on the warehouse with ≥30% saving
    • Own a data-contract or schema-evolution policy for your team
    Salary range₹19L – ₹27L
  5. Stage 5Year 4+

    Senior trajectory

    Lead the data platform for a product line. The senior band converges with platform / backend at GCCs and steeper at product companies (Walmart / Razorpay / ThoughtSpot).

    • Architect multi-source ingest + governance for a regulated product
    • Mentor 2 ICs; review their DAGs + dbt models weekly
    • Set the data SLA framework for the org; defend it in planning
    Salary range₹27L – ₹38L
