1. Connecting new data types and maintaining existing pipelines
2. Improving observability in data import pipelines
3. Working on business logic which is necessary for data to work in charting, scanning, backtesting, custom JS scripting etc.

1. Experience establishing cloud infrastructure via Terraform. AWS Lambda + SQS is a bare minimum.
2. Strong expertise in Node.js. At the very least, you need experience profiling, debugging a memory leak and an event loop jam in a Node.js service. Some services handle tens of thousands of messages per second, some pipelines handle gigabytes of data with limited RAM, that’s why.
3. Experience working with PostgreSQL and MongoDB with no ORMs.
4. Experience dealing with massive data (both “read a lot” and “write a lot”) in PostgreSQL.
5. Strong understanding of ideas of both OOP and functional programming. We use both, depending on a component and a goal.
6. Capability for testing your work well. Both writing automated tests (units, function, e2e) and running checks by doing what customers do.
7. Capability for figuring things out. All data vendors are different, all APIs are different and every kind of data has its own scale. 
8. Capability for building simple solutions for complex problems. Simplicity of solutions is the king here.
9. Hands-on experience trading or designing strategies will be a significant bonus.
