Data Engineer - Python, Data Processing & Acquisition

Job description

We are hiring a hands-on Data Engineer with 5+ years of experience to develop and maintain data acquisition, processing, and delivery workflows for our global clients. The role focuses on acquiring data from multiple sources — Excel files, APIs, databases, and websites — and transforming that data into reliable, high-quality datasets for business use. The ideal candidate is highly proficient in Python and Pandas, comfortable working with imperfect real-world data, and capable of building maintainable automation solutions that support ongoing business operations. This role emphasizes practical data processing, data quality, workflow automation, and troubleshooting over large-scale distributed data engineering technologies.

• Implement business rules, tagging, classification, and data standardization processes.

• Handle missing values, duplicate records, inconsistent formats, and other data quality challenges.

• Build reusable and maintainable data transformation components.

• Automate ingestion and processing of Excel, CSV, JSON, and other file-based data sources.

• Handle varying file structures, multiple worksheets, inconsistent schemas, and formatting issues.

• Generate standardized output datasets and reports.

• Integrate with internal and third-party APIs to extract and load data from external systems.

• Handle authentication, pagination, rate limiting, retries, and error recovery.

• Monitor and troubleshoot data acquisition workflows.

• Develop and maintain web scraping and data extraction solutions when required.

• Analyze website structures and network requests to identify efficient extraction methods.

• Support collection of external data from public and third-party sources, and maintain existing scraping workflows as source websites evolve.

• Debug and maintain existing Python-based data workflows; investigate production issues and data discrepancies.

• Improve reliability, performance, and maintainability of existing processes.

• Develop logging, monitoring, and operational support mechanisms.

• Support deployment and operation of data workflows within AWS — working with Amazon S3, AWS Lambda, Amazon RDS, Amazon SQS, and Amazon CloudWatch.

• Participate in automation and cloud-based operational improvements.

• Working time: Monday to Friday, 14:00-23:00 

• Start date: ASAP

• Engagement: Long-term

• Language: English professional mandatory
