• Implement efficient algorithms and data transformations to support analytical and operational needs
• Optimize performance, throughput, and reliability of distributed data workflows
• Collaborate closely with Data Scientists, Product Managers, and other engineering teams to translate requirements into scalable solutions
• Implement monitoring, alerting, and observability for data workloads
• Ensure code quality through best practices such as code reviews, testing, CI/CD, and documentation
• Contribute to architectural decisions and technical strategy for the data platform
• Troubleshoot production issues, perform root‑cause analysis, and optimize system stability
  
  
  

Qualifications

• 5+ years of backend software engineering experience, with a strong focus on Python
• Hands-on experience with Apache Spark, Databricks, or similar distributed-processing frameworks
• Proven ability to design and optimize high-scale data pipelines handling large datasets
• Strong understanding of distributed systems, parallel processing, and performance tuning
• Familiarity with cloud environments (Azure, AWS, or GCP)
• Experience with modern CI/CD processes, testing frameworks, and code-quality standards
• Strong understanding of data structures, algorithms, and system design
• Excellent problem-solving skills and ability to work independently
