About the role:

We're hiring a Senior Data Engineer who's done more than execute pipelines inside someone else's design. If you've independently architected a data model — Star Schema, Data Vault, or a Medallion (bronze/silver/gold) Lakehouse — and can walk through the trade-offs you made, not just the tools you used, keep reading.

What you'll actually own:

Design and own dimensional and Lakehouse data models from scratch — Star Schema, Snowflake Schema, Data Vault, or Medallion architecture, chosen for the problem, not defaulted to
Build ETL/ELT pipelines you'd trust without watching them — CDC, incremental loads, watermarking, real error handling, the stuff that doesn't page you at 2am
Go deep on Databricks (Delta Lake, Unity Catalog, cluster tuning, Z-Order) or Snowflake (multi-cluster warehouses, clustering keys, performance tuning) — architecture and platform ownership, not notebook execution
Use PySpark and Spark SQL for real distributed processing at scale
Write SQL that holds up under production load, not just queries that return the right answer once

What we need to see, not just hear about:

4–8 years of hands-on data engineering, with modeling you designed independently — able to explain why you chose the schema you chose
Real ownership of Databricks or Snowflake at the architecture level, not just usage
Strong Python and PySpark
Azure (ADF, ADLS, Synapse) and/or AWS (S3, Glue, EMR, Redshift) — production experience, not a course completion
Bachelor's in Computer Science, Data Engineering, or related field

Nice to have, not a gate:

Power BI or Tableau — genuinely valued, but we won't screen out a strong architecture-first engineer who partners with BI rather than builds dashboards themselves
Kafka or Kinesis, dbt, Microsoft Fabric
DP-203, Databricks Data Engineer Associate, SnowPro Core, or PL-300

We work with enterprise clients where the data problems are genuinely hard and the ownership is real. If that's the kind of work you're looking for, we should talk.

Benefits:

At Calfus, we value our employees and offer a strong benefits package. This includes medical, group, and parental insurance, coupled with gratuity and provident fund options. Further, we support employee wellness and provide birthday leave as a valued benefit.

Calfus is an Equal Opportunity Employer.

We believe diversity drives innovation. We're committed to creating an inclusive workplace where everyone—regardless of background, identity, or experience—has the opportunity to thrive. We welcome all applicants!
