Big Data Engineer, Part-Time AI Data Engineering - Remote (United States)

• $30–$80 per hour

• 100% remote

• Part-time

• Fully flexible schedule

Work on the cutting edge of AI data systems, on your own schedule, and get paid for the data engineering expertise you already have.

The AI systems everyone is talking about are trained and tested with the help of real data engineers. The teams building them need big data engineers who can create realistic pipeline and database tasks, judge how well the AI handles them, write the solution a professional would give, and explain exactly where the AI falls short. Your judgment becomes part of how the next generation of AI models works with data. This is that work, done remotely around your current job.

What you'll do

• Create realistic data engineering tasks involving large-scale pipelines and data integration

• Review AI-generated solutions for Python processing and distributed data systems

• Write the expert solution for database optimization and data warehousing

• Explain where and why the AI falls short on reliability and data quality

Why this is worth your time

• Get paid $30–$80 an hour to build real AI skills, on top of your current job

• Work directly with frontier AI tools and see how they are built, tested and improved, experience most data engineers will not have for years

• Build a career edge for what comes next: AI is reshaping data engineering, and the engineers who understand it from the inside will lead that change

• Fully remote and flexible, no fixed shifts, no commute

Who this is for

• Hands-on experience with large-scale data pipelines, including their development and upkeep

• Advanced proficiency in Python for automating and integrating data processing

• Professional fluency in English, plus strong knowledge of relational and NoSQL databases and frameworks for distributed processing, including Hadoop, Spark or Flink
