- Highload systems management
- Performance analysis and optimisations
- Data streaming
- Search engines, recommendation systems, knowledge graphs or graph databases
- Resources management
- Engineering team management
- Interviewing candidates
### The most attractive project could look like:
Get in the project where everything is a mess with responsibilities with goal to set up processes to deliver high quality stable features in time and to make a team to work effective; work with people and their desires and motivation; a little of coding with a lot of code review; a huge amount of communication; direct responsibilities in architecture and codebase maintainability, making a decision in lack of context, technologies maintaining, features planning → decomposition → delegation. Great advantage is English is the only language for communication
