About the role

Join the ECI Group's Professional Technical Services Network as a Principal Data Engineer. This is a Houston based a six-month contract role with an anticipated March 30, 2006 start date and ending on September 30, 2026.

NOTE: You must be a US Citizen or Permanent US resident to qualify for the position.

Roles and Responsibilities:
The Principal Data Engineer is the one who conceptualizes and designs data foundations and end to end solutions including data platforms for the Shell Business to maximize value from data. The role helps create a data-driven thinking within the organization, not just within IT teams, but also in the wider business stakeholder community. A Principal Data Engineer is expected to be a subject matter expert, and an active thought partner in the organization's data strategy and the key driver to define the Vison and Data Strategy for robust and future ready IT solutions

Role Objective
This is not a standard data engineer role. We are looking for a deeply technical, hands-on individual contributor who can:

Diagnose performance, latency, and cost issues in a large-scale cloud data platform
Take a top-down, platform-level view across multiple projects
Improve architecture, efficiency, and cost optimization, not just write Spark code
Act as a technical problem-solver and mentor, guiding other data engineers

This person is expected to make the platform better, not just execute tasks.

Current Platform & Architecture
Data Flow:

On-premise systems → Cloud (Azure)
Streaming ingestion → Azure Data Lake Storage (ADLS)
Data processed into two separate containers:
- Crude trading
- Product trading

Technologies in Use:

Qlik Replicate (formerly Attunity)
- Streaming data from on-prem to Azure
Azure Data Lake Storage (ADLS)
Databricks
- Delta Live Tables (DLT)
- Spark / PySpark
Python
SQL (complex queries and procedures)

Key Challenges the Role Is Meant to Solve
1. Data Latency

High-volume streaming data
End-to-end latency issues that need root-cause analysis

2. Databricks / DLT Cost Spikes

DLT costs are far higher than expected
Known contributors:
- Very high data volume (expected)
- Inefficient lookup logic used to split data into separate containers
The current solution works but is not optimal

Note: This role exists because generic recommendations are not enough.
