Data Platform Developer Trainee

Responsibilities: 

Help us build impactful data products!

• Build real stuff on a cloud data platform: contribute to features and improvements across ingestion, transformation, and serving layers
• Create & maintain ELT pipelines: bring new data in, transform it reliably, and keep it running as requirements evolve
• Turn business questions into dashboards: collaborate with business stakeholders to create and improve reports and visualizations
• Help keep these platforms healthy: support deployments, monitoring, and troubleshooting (you’ll learn how “production” really works)

Requirements: 

If you don’t tick every box, apply anyway - curiosity and willingness to learn matter more than buzzwords. You don’t need to be “done learning.” You do need to be ready to build and grow fast.

• SQL fundamentals: you can write queries with joins and aggregations
• Programming basics: experience with Python (preferred) or another modern language
• Git basics: you understand version control concepts (commits, branches, collaboration)
• Motivation: you’re genuinely interested in data engineering and how data powers analytics and business decisions
• Curiosity about applied AI: you’re interested in how data enables AI/ML
• AI-assisted development mindset: you use AI-powered IDE features and coding agents to accelerate learning and delivery while keeping quality and correctness in check.
• You’ve done something practical: you’re pursuing a STEM degree and have at least one of these:
  • relevant university courses, or
  • online courses (Udemy/Coursera), or
  • a data project (university or personal)
• Student status: active student with at least 1 full semester remaining
• Availability: at least 20 hours/week
• Language: conversational English

Nice to have — bonus points, not blockers (curiosity outweighs experience)

• Experience with relational databases and basic database design
• Familiarity with cloud data warehouses / lakehouses and analytics modeling concepts (e.g., star schema)
• Hands-on exposure to modern data platforms (Snowflake, BigQuery, Databricks)
• Familiarity with BI tools (Power BI, Tableau, Looker)
• Exposure to a major cloud platform (AWS/Azure/GCP)
• CI/CD principles and an interest in automation
