I need an experienced engineer who can sit with me in Pune MH India and provide hands-on, offline technical support for daily data engineering tasks. The focus is strictly on Python and PySpark: reviewing code, untangling bugs, optimising Spark jobs, and guiding me through best practices as we build and maintain data-processing pipelines. This is not a remote, on-call role; I’m looking for someone who can be physically present in Kharadi/Viman Nagar/Magarpatta Area—pair programming, white-boarding solutions, and helping me push features all the way to a clean commit. If you have solid production experience with Python, strong command of PySpark’s RDD/DataFrame APIs, and the confidence to troubleshoot performance issues on the spot, let’s talk about a regular schedule that works for both of us.
