How to Apply for Senior Data Engineer – AI & Analytics

at EnPhase Energy

🏢 About EnPhase Energy

EnPhase Energy is a pioneer in advanced solar solutions, committed to a sustainable, solar-powered planet. Working here means contributing to cutting-edge renewable energy technology while enjoying the flexibility of a remote-first culture.

About This Role

As a Senior Data Engineer, you will design and optimize PySpark pipelines and SQL transformations that power AI-driven analytics for solar energy systems. Your work will directly enable smarter energy management and predictive maintenance, making a tangible impact on global sustainability.

💡 A Day in the Life

You'll start by reviewing pipeline performance metrics and tweaking PySpark jobs for efficiency. Mid-morning, you might collaborate with AI/ML engineers on a feature engineering pipeline for a predictive model. Afternoons involve building SQL transformations for a new data mart, followed by a sync with the team on streaming data quality issues.

🎯 Who EnPhase Energy Is Looking For

  • Experienced data engineer with 4-7 years of hands-on work in PySpark, Python, and advanced SQL (CTEs, window functions, query tuning).
  • Proven track record of implementing AI projects using models like Claude, GPT, or Gemini, and building feature engineering pipelines for ML teams.
  • Deep understanding of data warehousing (star/snowflake schemas, SCDs) and experience with streaming data via Kafka or Kinesis.
  • Passionate about renewable energy and excited to apply data engineering to solar analytics and sustainability.

📝 Tips for Applying to EnPhase Energy

1

Highlight specific PySpark projects where you optimized pipelines for batch and streaming data at scale.

2

Mention any experience with AI/ML collaboration, especially feature engineering for models like GPT or Claude.

3

Showcase your SQL expertise with examples of complex queries using CTEs and window functions for analytics.

4

Tailor your resume to emphasize dimensional modeling (fact/dimension tables, SCDs) and data mart design.

5

Include a brief note about your interest in renewable energy and how your skills align with EnPhase's mission.

✉️ What to Emphasize in Your Cover Letter

['Your experience with PySpark and streaming pipelines (Kafka/Kinesis) for real-time data processing.', "How you've collaborated with AI/ML teams to build curated datasets and feature engineering pipelines.", 'Your proficiency in dimensional modeling and data warehouse design for analytics and reporting.', 'Your passion for sustainability and how you see data engineering driving solar energy innovation.']
