About the Project

We are looking for a Data Engineer to join the team responsible for the core data layer of our central system. At the foundation of our work lies a PostgreSQL database, which powers the organization’s main application. Our goal is to ensure that data is consistent, reliable, and efficiently processed — delivering both high performance and high-quality information. This role gives you the opportunity to work directly with the data that forms the heart of the organization and to contribute to shaping a critical part of the system’s architecture.


Responsibilities

  • Design, write, and optimize SQL queries for efficient data retrieval and storage

  • Develop Python-based data processing components and user-facing outputs

  • Ensure data consistency, accessibility, and performance across the system

  • Write and maintain automated tests in Python

  • Collaborate with other engineers to continuously improve system quality and reliability


Requirements

  • Strong knowledge of SQL and practical experience working with relational databases and PostgreSQL knowledge

  • Proficiency in Python for data processing and automation

  • Methodical and analytical approach — ability to fully understand problems before drawing conclusions

  • Motivation to grow and continuously learn

  • Ability to work effectively as part of a team, bringing positive energy and collaboration


Nice to Have

  • Experience with performance tuning and large-scale datasets

  • Familiarity with database design and data modeling principles

  • Knowledge of testing frameworks in Python


Why Join This Project?

  • Opportunity to work on the foundational data layer of a key organizational system

  • Direct impact on the quality and performance of data used across the company

  • No legacy maintenance — focus on clean, efficient, and scalable solutions

  • Collaborative and growth-oriented environment
