This involves writing clean, efficient code and ensuring that all data pipelines meet strict uptime and performance SLAs.

Beyond pure development, you will collaborate closely with cross-functional teams to understand business requirements and translate them into technical specifications. You will often act as a bridge between operational teams and data consumers, ensuring that the data provided is accurate, timely, and accessible. You are expected to take ownership of your projects, identifying opportunities for automation and process improvement to reduce technical debt and increase operational efficiency.

Q: Are there remote or hybrid options? Location requirements depend on the specific team and region. Always clarify the expected working model (e.g., hybrid, office-based) with your recruiter during the initial screen.

• Prepare your stories: Use the STAR method (Situation, Task, Action, Result) to structure your behavioral answers. This keeps your responses concise and focused on your specific impact.
• Focus on the 'Why': When discussing your past projects, don't just explain what you did. Explain why you chose a specific tool or architecture over an alternative.
• Ask meaningful questions: Use the end of the interview to ask about the team's current challenges or the technical roadmap. It shows you are thinking about the long-term success of the department.
