The experience we are looking for:

• Designing, implementing and debugging large-scale data infrastructure systems, and identifying their performance bottlenecks
• Understanding of long-term impacts of key design decisions and handling failure scenarios

We value ownership and innovation, and we build our teams with that in mind. We want each team to be responsible and accountable for what they ship. We also don't want to reinvent the wheel every time, so we try to get alignment in terms of practices and technologies. Our philosophy to achieve this is relying on excellent tooling and automation over policies and processes.
