We have an urgent job opening for our client Nineleaps Technology Solutions Private Limited.

Exp: Min 5 yrs

Location: Bangalore (Sarjapur Road)

Key skills:Data Engineer, Python, SQL, Systen Design Architecture, Financial Transaction Data etc.

About the Role: We're looking for a Senior Data Engineer with strong data architecture and system design skills to design, build, and own end-to-end production pipelines powering analytics and decision-making across the org. The role centers on deep Python + SQL expertise, robust transaction-level fact tables, and rigorous data quality and auditability, ideally within a finance, risk, or compliance data domain. Internal candidates familiar with Uber's data platform stack (Piper/uWorc, Databook, uSecret, DSW, SourceGraph, Query Builder, OneETL) will be prioritized.

Location: Bangalore

Experience: 6+ Years

What You'll Do

Own data architecture and system design decisions for pipelines and data models - grain, partitioning, schema evolution, and scalability tradeoffs.

Take end-to-end ownership of pipelines in production: design, build, deploy, monitor, and operate.

Design and build transaction tables (append-only, immutable event/transaction-grain fact tables) alongside standard fact/dimension models using medallion (bronze/silver/gold) architecture.

Build and support pipelines for finance, risk, or compliance use cases where accuracy, auditability, and data lineage are critical.

Implement data quality and auditability controls: validation checks, reconciliation logic, anomaly detection, and audit trails for every pipeline you own.

Write complex, cross-dialect SQL (MySQL + PostgreSQL): window functions, multi-layered CTEs, CASE-driven logic, COALESCE/NULLIF, type casting, and date/timestamp handling.

Build idempotent reload patterns (DELETE+INSERT), UNION ALL/set operations, and templated (Jinja-style) SQL including handling for late-arriving/corrected transaction records without double-counting.

Orchestrate Airflow-style DAGs (Pipeline/BaseTask,



ExternalTaskSensor for cross-pipeline deps) with secure credential handling via uSecret.

Build Python ETL tooling: pandas (CSV DB), SQLAlchemy + raw drivers (MySQLdb, psycopg2), type hints/dataclasses, class-based pipeline design.

Integrate with Google Drive/Sheets APIs; build YAML-driven pipeline configs; handle Piper staging/user_staging quirks.

Own CI/CD for pipelines via standard Git workflows.

Use Uber's internal stack day-to-day: OneETL for pipeline authoring, Piper/uWorc for scheduling, Databook for lineage, uSecret for credentials, DSW notebooks for CSV/table work, SourceGraph for code search, Query Builder for ad hoc SQL. Document data models and pipeline logic for maintainability, keeping compliance/audit needs in mind.

What We're Looking For

Must-Have:

6+ years in data engineering.

Robust data architecture and system design skills to make sound tradeoffs on modeling, partitioning, and scalability, not just write queries.

Demonstrated end-to-end production ownership of data pipelines from design through deployment, monitoring, and operational support.

Expert-level Python + SQL as the primary toolset.

Hive/Hadoop is a nice-to-have only.

Robust data quality and auditability practices - validation, reconciliation, anomaly detection, audit trails.

Experience working with finance, risk, or compliance data - comfort with the heightened accuracy, auditability, and data-lineage requirements typical of these domains.

Proven experience designing and building transaction/fact tables.

Expert SQL (window functions, CTEs, CASE logic, cross-dialect MySQL/PostgreSQL).

Strong Python (pandas, SQLAlchemy, type hints/dataclasses, class-based pipelines).

Airflow-like orchestration experience (Piper/uWorc a plus).

Solid data modeling fundamentals (fact/dim, normalization, medallion architecture).

YAML-based config experience; standard CI/CD and Git workflows. Strongly Preferred (Uber Internal Tooling): Piper/uWorc, Databook, uSecret, DSW, SourceGraph, Query Builder, OneETL.

Nice-to-Have: Hive/Hadoop or Spark experience.
