• Partner with the data engineer and backend teams to ship features that push our services forward.
• Contribute ideas to improve architecture and guide data best practices.

🔓 What You Bring:

• 3-5+ years of experience in Python for data engineering or ETL development.

• Collaborative communicator who enjoys working across teams.
• Bonus: experience with web scraping, APIs, or data ingestion at scale.
