- Work with large-scale IoT data: ingestion, processing, storage, and optimization for performance and cost.
- Write and optimize advanced database queries in PostgreSQL and SQL Server
- Collaborate with other engineering teams to define technical direction, share best practices, and review designs.
- Contribute to engineering excellence via code reviews, testing strategies, documentation, and continuous improvement of standards.
