- Develop reusable frameworks and components to improve engineering productivity, data processing efficiency, and operational reliability.
- Analyze and optimize large-scale data workloads for performance, scalability, reliability, and cloud cost efficiency.
- Implement data quality, validation, monitoring, and observability across data pipelines and datasets.
- Troubleshoot complex data, pipeline, infrastructure, and production issues and drive root-cause resolution.
- Participate in architecture and design discussions and contribute to technical decisions involving data platforms and cloud technologies.
- Collaborate with Product, Analytics, Data Science, Architecture, and other engineering teams to deliver high-quality data products.
- Participate in code reviews, design reviews, testing, debugging, and production support activities.
- Follow engineering best practices around CI/CD, automation, security, reliability, and operational excellence.
- Evaluate and adopt emerging technologies that improve data engineering productivity and platform capabilities.
- Contribute to technical documentation, engineering standards, and knowledge-sharing across the team.
- Explore and adopt AI-assisted development tools such as GitHub Copilot, Claude, and similar solutions to improve developer productivity and engineering efficiency.
- Identify practical opportunities to leverage Generative AI for code development, code reviews, debugging, documentation, data analysis, and automation.
- Stay current with emerging AI and data engineering technologies and evaluate their applicability to Target's technology ecosystem.
- Bachelor's degree in Computer Science, Engineering, Information Technology, or equivalent practical experience.
- 5+ years of experience in software or data engineering, with significant experience building and supporting large-scale data platforms.
- Strong hands-on experience with:
- Apache Spark
